THESIS

The Project

The roads travelled to reach “the Sound” have created a conceptual cross-road, where state of the art digital technology and traditional techniques have gone their separate ways.

They both have benefits of a different nature, yet are capable of merging together to achieve much higher Sound quality levels.

The Thesis amplifiers are born from these considerations. The parts related to signal amplification are manufactured using the highest level of analog technology while, at the same time, the input section along with the processing and monitoring functions of the amplifier are the result of the most advanced digital technology.

The TH due is a two-channel power amplifier, designed for use in car. It is technologically progressive, featuring original circuitry, with extraordinary sound, consistent with Audison tradition.

Sections:

This manual is divided into sections allowing the use of the TH amplifier in standard settings or using its specific features in “digital” settings. Each section is marked by its corresponding bookmark.

General Part:

The TH amplifiers need to be connected like any other amplifier, in compliance with safe working conditions. Installation as well as power supply and speaker connections have to be made properly, following the standard methods a specialty store normally follows.

Classic Domain:

Despite the endless settings and customising possibilities ASC (Amplifier Status Controller) offers, the TH amplifiers can also be used in a traditional way, taking advantage of the analog inputs and of the controls which provide the signal to the final stages.

The setting of the sensitivity, stereo or bridged mono configuration, the inputs sensitivity, the electronic crossovers on slide-through boards as well as the PRE bypass out, anyway let to include the TH within the traditional systems or to build amplifying chains with absolute audiophile quality.

Digital Domain:

The TH amplifiers feature ASC (Amplifier Status Controller) which provides several factory functions for the complete control of all the amplifier's functions.

Heart of the system is a digital power microprocessor. It manages the amplifier functions and communicates with the user through a control panel as well as the Display Monitor, featuring the DRC remote control or, in a more complete and direct way, through the ACNet Audison Controller Network software.

The ASC menu allows the amplifier set up, monitors the working conditions, viewable through a Status Monitor feature, also making the data available on the display intermittently. A USB connector enables the connection of the system to a computer, while the AC Link (Audison Control Link) allows the creation of communication network. The software will take care of the functional operations for all the amplifiers within the whole chain (system), providing a simple and complete interface. A revolutionary method for configuration which, up to know, were impossible to achieve with traditional designs.

Electronic Crossover

Representing a high-end solution, the simplicity and power of the analog system found in the HV venti is thrust forward again in the TH, making use of the amplifiers versatility.

The crossover ONLY acts on the amplifier power output, not on the PRE OUT output which is always a bypass.

The alignment is a Butterworth type as, when either of the TH amplifiers is set up in a mono configuration, the slope of the filter can be set for 24 dB Oct operation.

Each TH due is factory provided with:

• a TH-MXR.1 crossover board, containing the electronics required to set, through selectors, the operation mode as well as the Low-Pass filter slope.
• eight crossover modules, featuring high-precision resistor packs corresponding to 32 cut-off frequencies placed at equal distance from 18Hz thru 7.5kHz.
• two customisable crossover modules (to build them, see the "Custom Module" section in this manual).

Modules

In order to build a Standard System you have to:

1- Insert the TH-MXR.1 board with its relative filter module (if required);
2- Connect power supply;
3- Connect the speaker system;
4- Connect signal inputs and remote turn on;
5- Select stereo mode on the Input Controls Panel;
6- Adjust sensitivity on the Input Controls Panel "LEVEL";

In order to add DRC to the System you also need to:

7- Set ADRS on the Front Panel (in position 1 for instance);
8- Set Amp ID (on FRONT for instance) in the ASC Setup Amplifier; this way DRC will be enabled to adjust general Volume, Balance and Fader.

In order to adjust the system through the ACNet:

On this system the steps 1, 2, 3, 4, 5 and 7 need to be performed.

The Software will temporarily bypass the DRC functionality in order to manage in a more direct and easier way all of the amplifier functions during the adjustment and modifying phases, including input sensitivity adjustment along with peak detector.

REMARK:

Into the amplifier ASC, the Dual Power and Runtime Monitor functions will anyway stay active (by default) and ready to change it directly (see page 52 and following pages).

Example: Two Way + bi-amplified Sub, TH amplifier Analog Input

In order to build a Standard System: You have to follow same steps as per the above example. The only difference is for point 4, where TH (2) has to be set in Mono configuration; In order to add DRC to the System you also need to: 7-Give the Front Panel ADRS of each of the two amplifiers a different setting (Example: 1 and 2); 8- Configure the Amp ID on the ASC Setup Amplifier of the two amplifiers by setting TH (1) as Front and TH (2) as Sub; 9- Set the TH (1) ID Preout as TH Amp, to let DRC adjust general Volume, Balance, Fader as well as Sub Volume. In order to adjust the system through the ACNet: Once the steps 1, 2, 3, 4, 5 and 7 have been performed, the Software will temporarily bypass the DRC in order to manage in a more direct and easier way all of the system functions. REMARK: On ASC Dual Power and Runtime Monitor will anyway stay active (by default) and ready for changes (see page 52 and following pages).

In order to build a Standard System:

You have to follow same steps as per the above example. The only difference is that TH has to be set up in Mono configuration. Also, it becomes the audio chain first amplifier, thus being able to manage the whole system;

In order to add DRC:

7- Set ADRS on the Front Panel (in position 1 for instance);
8- Set the Amp ID in the ASC Setup Amplifier as Sub.
9- Set the ID Preout as Front, to let DRC adjust general Volume, Balance, Fader as well as Sub Volume.

In order to adjust the system through the ACNet:

Once the above listed steps have been performed, the Software will temporarily bypass the DRC in order to manage in a more direct and easier way all of the system functions.

REMARK: On ASC Dual Power and Runtime Monitor will anyway stay active (by default) and ready for changes (see page 52 and following pages).

THESIS

ASC (AMPLIFIER STATUS CONTROLLER)

The TH amplifiers ASC unit is the operational interface, programmed to control all of the amplifier's functions. The user can interact with the microprocessor which, without interfering with the sound, will provide control for any possible adjustments. This manual section is especially thought for those who want to get the most of these amplifiers exclusive features.

Some functions are automatic and transparent to the user, others require support during the installing, adjusting or modifying phase. By accessing the ASC a set of menus will show, offering specific entries which the user can operate on:

- Setup Amplifier:

Main Input: the user can decide what kind of source the amplifier has to drive;

Amp ID: the user can name the amplifier identifying the function the amplifier performs inside the system;

ID Preout: the user can name the pre-amplified section so it is possible to manage it inside the system;

X-Over Slope: the user can select the Low-bass filter slope (only in Mono mode);

Dual Power: the user can choose the sound quality and the power the amplifier has to work at;

- Status Monitor: the user can monitor the amplifier working status;

- Runtime Monitor: the user can select it on the Display to intermittently have information on the amplifier status shown.

Some of these functions need a remote control communicating with the microprocessor. Inside this manual, where necessary, the presence of the DRC (Digital Remote Control) is underlined. The DRC also adds some specific functions which you can read on their relative section from page 61 on.

INPUTS AND PRE-AMPLIFIER

The TH amplifiers combine an analog and digital section in one device; keeping the two sections on separate PCBs, although mounted within the same sub chassis.

Each amplifier features a state-of-the-art digital encoding section as well as a 24 bit 192 kHz converter. The S/PDIF optical input accepts PCM stereo signals; also, the innovation consists in the fact the TH amplifier can be driven in digital directly and, as a consequence, the whole system too, if a system in multi-amplification configuration with the re-launch of this digital signal to other Thesis TH amplifiers through the AD Link system (Audison Digital Link). Each amplifier independently takes care of the D/A conversion. While in the Digital Input mode the DRC needs to be connected, so it works as an actual general volume and source selector control, capable of repeating all the low frequency controls (Master Volume, Balance, Fader, Sub Volume).

The AD Link connectors on the TH input panel can receive the digital signal from sources or multi-channel processors featuring the afore-mentioned outputs (Audison Bit One) and re-launching the digital signal to the amplifiers chain through a Cat.5 certified shielded cable equipped with an RJ45 connector (provided).

In the following pages of this manual we will explain how to perform the amplifier setup and how to connect it in all THESIS or mixed chains.

ASC - Amplifier Status Controller

Functions Description

TH due audison TH due (0) Default display 1 2 3 MENU ENTER DOWN UP 4

1 • TH due STATUS DISPLAY: it is the visual element of the ASC system, a back-lit two line 32 character LCD display; While working, it can relate all of the configuration parameters memorised by the amplifier during the installation, as well as the operational status of the amplifier.

The following pages address all the messages and information which from time to time the display can show. In case of protection intervention, the state of protection is permanently displayed, until the problem is resolved or until the amplifier is reset;

2 • MENU: this switch enables the ASC and shows the first available entry. Each time this switch is pushed while the amplifier is normally working, the ASC displays the first available entry, not the last you worked on. No matter which step of the management you are at, if you push the MENU button, you exit the ASC management and you are automatically taken back to the first display screen (Default display) without saving any changes.

Remark: No matter which step you are at of the management software, if you don't operate on the switches for 5 seconds, the ASC automatically goes back to the first display screen (Default display) without saving any changes.

3 • ENTER: this switch is to:

- confirm the selected entry, - store it in the memory, - move to the following menu entry. The ASC performs these three activities automatically. If you modify the menu entry you are working on and then you push "enter", the display will show:

then the display will show the next entry. The changes will only be made once ENTER is pushed.

4 • UP - DOWN: through these switches the user can browse through the entries available inside the different menus. According to the function you are checking, they allow you to modify your choice which, then, will have to be confirmed by pushing ENTER.

ASC - Amplifier Status Controller

Setup Amplifier: Main Input

The first step to set the amplifier up is to select the main input the TH will use to get the signal. As soon as you turn the amplifier on, the PRE analog input is selected by default. By changing this entry the user can also take advantage of the other operational modes. From next time you turn the TH on, it will use the last selected entry.

If another input is used, the DRC is required. In that case, if for any reasons it is disconnected, all the setup settings and low level controls will reset back to the default settings, unless the DRC is re-connected, in which case they restore. (See page 36)

In multi-amplified systems, in order to cascade other amplifiers when using the analog input, the Pre Out analog output MUST be used. In this case, the amplifier can use the IN OPTICAL digital input or the pre-amplified input. You can select either input only through the DRC. In multi-amplified systems, select this entry only on the first chain TH amplifier, which is the one physically receiving the signal from the digital source. In this case, the amplifier receives the input signal from another TH amplifier through the AD Link digital connection. In multi-amplified systems where both the analog and digital inputs are connected, when moving from a source to another through the DRC, each amplifier will automatically change input. Select this entry when the amplifier is connected through the AD Link to a system managed by an Audison external processor (such as the Bit One). This entry gets active and is displayed only when the processor is connected. If for any reason the processor is disconnected with the amplifier on, the ASC will go back to the default settings.

Digital Inputs

How to adjust the volume control and input selector using a digital source

In the following pages you will find examples of how to connect the TH to a system driven by sources using the digital input. In order to use the TH IN OPTICAL digital input and therefore its D/A internal converter the DRC Digital Remote Control MUST be connected to the TH amplifier.

The DRC will perform the function of selecting the source by selecting between Analog Input and Optical Input, thus allowing the control of Main Volume, Subwoofer Volume, Balance and Fader.

If the last setup working conditions are no more valid, that is if you disconnect the DRC and you had changed the default conditions, the ASC will automatically go back to use the PRE Analog Input. In this case Fader and Balance will go back to central position, while general Volume and Sub Volume will go back to 0 dB (maximum value). The TH display will show the following information:

DRC not found: defaults loaded

DRC Vol: 00.0dB = TH MAX Power Output audison Volume: -00.0dB L audison TH SSS

Warning:
When using the optical digital input you have to use the DRC as main volume control. If the DRC volume control is at 0 dB it equals to the amplifier undistorted maximum output power.

To check all the functions and the DRC connection, see pages 61 ÷ 63

Front Panel

How to achieve same output volume level using an analog source (with its own volume control) and a digital source

Once you have adjusted the system, therefore once the amplifiers input sensitivity has been adjusted, you can adjust the digital source volume level so that when selecting the analog or the digital source no difference in sound is perceptible while listening. Once performed this adjustment, we would recommend that you use the DRC volume control as general volume control.

1) On the DRC select the source: Optical Input
2) On the DRC adjust volume until you can read -30.0 dB
3) Insert the Test CD provided with the amplifier into the source connected to the digital input
4) Select track # 05 (sinusoidal signal 1 kHz / 0 dB)
5) Using a multimeter (True RMS) measure the voltage on the speaker terminals
6) On the DRC select the source: Analog Input
7) Do not change the set volume (-30.0 dB)
8) Insert the Test CD provided with the amplifier into the source connected to the digital input
9) Select track # 05 (sinusoidal signal 1 kHz / 0 dB)
10) Adjust the volume of the source connected to the analog input until, using a multimeter (True RMS),
11) you measure the same voltage on the speaker terminals
12) Use the DRC as main volume control

ASC - Amplifier Status Controller

Setup Amplifier: Amp ID

TH in Stereo mode

AMP ID stands for Amplifier IDentification. The AMP ID is a way to identify the task the amplifier performs inside the system. The AMP ID does not affect the electric functioning and does not act on the amplifier electronic crossover. The AMP ID is fundamental to adjust Volume, Balance, Fader as well as Sub Volume when the DRC is connected. The ASC recognises the function the amplifier has been given through the ID. By acting on the DRC and adjusting Volume, Balance, Fader as well as Sub Volume, as a consequence also the signal to the amplifiers will be managed.

Example:

If the AMP ID-Front is assigned to the TH amplifier, by operating on the DRC its general volume, as well as the right/left balance, will change. Also, by setting the Fader on Rear you will hear the volume diminishing; however, no change will be perceived if you operate on the DRC Sub volume.

Vice versa, if the AMP ID – Subwoofer is assigned to the TH amplifier, by operating on the DRC its general volume, more specifically the Sub volume, will change; however, no change will be perceived if you operate on the right/left balance or moving the Fader.

In order to avoid errors, you should assign the ID according to the speakers connected to the amplifier.

The AMP ID can also be assigned to the PRE OUT output. This function is extremely useful in case the TH amplifier is added to a pre-existing system featuring not only TH amplifiers or if you want to add to the TH system a non-TH amplifier. This way you can anyway know the non-TH amplifier function as well as adjust its volume. The AMP ID - Preout provides the ability to expand the system endlessly, keeping the low level parameters management functions through the DRC.

As the AMP ID – Preout does not operate on the electronic crossover, it does not put in any filters on the output signal! The signal on the PRE OUT output will always be exactly the same as the one on the selected input.

By selecting an AMP ID entry which takes advantage of the amplifier for the left channel, you can assign one single entry dedicated to the left channel to the ID Preout. Vice versa, by selecting an AMP ID entry which takes advantage of the amplifier for the right channel, you can assign one single entry dedicated to the right channel to the ID Preout.

This dedicated setting is only valid using the analog input.

How to adjust the PRE OUT analog output

As already said, the AMP ID can also be assigned to the PRE OUT output, but not only to it. Through the AC Net software also the PRE OUT sensitivity can be adjusted to align the gain of the amplifier connected to that output, thus adapting sensitivity according to the system general volume increase and decrease.

The procedure to perform this operation is the following:

1- Connect the (non-TH) amplifier to the PRE output.
2- Assign the ID - Preout.
3- Set the non-TH amplifier sensitivity to the minimum.
4- Through the AC Net slider, increase the output sensitivity until you get the desired volume.
5- Should it not be enough, increase the non-TH amplifier input sensitivity

Setup Amplifier : X-Over Slope with TH in Mono mode

When the amplifier is set Mono configuration, you can choose the crossover filter slope.

Select 1-12 dB/oct: in this case, the Low-pass slope switch on the TH-MXR module will not be active.

Select 2-24 dB/oct: when this option is selected, the Low-pass slope switch on the TH-MXR module will anyway be active, thus providing the ability to mechanically choosing between 12 and 24 dB/oct.

ASC - Amplifier Status Controller DUAL POWER & BIAS CONTROL

A revolutionary function called Dual Power was introduced for the first time in the HV venti.

Controlling the amplifier's output power configuration, this function allowed the predetermination of the amplifiers output power and of the grade of the outputs operational class. The digital interface enables expedient intervention by the user, setting up the amplifier's operational modes by operating on the power and bias current settings, all in real-time. In any case the result is a clear "sound customisation".

In this Setup section you can set the amplifier operational mode.

There are four possible presets:

Class A: to intensify the musical performance; you can not expect the amplifier to drive loads under 4 Ω under these conditions;

Hi-AB Class: it is the default mode, combining the characteristics of high class functioning, great capability of driving difficult loads and high power.

Hi-Current: Pure power, on any loads

Energy Saving: it sets the power emission to the minimum, allowing musical enjoyment for extended periods of time with the vehicles engine off.

When changing mode, you have to wait a few seconds to perceive the acoustic variations. The Dual Power is absolutely independent from the other settings selections. It will work both in Mono and in Stereo configurations, both with and without the crossover, both connecting a subwoofer and a tweeter to it. So we recommend you pay attention to select a functioning mode accepting the impedance load you applied to the amplifier. Check the following page for comparative charts with reference values.

How to change presets on the Memory (DRC required)

The TH uno can be set with only one operational mode at a time, while the DRC can manage four customisable memories.

1- Default: In standard configuration, without making any changes, if memory 1 is recalled from the DRC, all the TH amplifiers connected to the system will be working in Hi-AB Class mode (as it is the default setting), while selecting memory 2 they will be workin in Hi-Current mode and so on.
2- Customizing: by acting on both the DRC memories and the ASC control panel of the amplifier, you can create custom setups. For instance, if you want the TH amplifiers to anyway work in A-Class mode, you will have to act on the setup as follows:

• Select memory 1 on the DRC by pressing first SEL and then 1
• Select the A-Class preset on the ASC by accessing to its corresponding setup
• Repeat this operation for each DRC memory
• Repeat this operation for each TH present in the system

Example: In a three-way + Sub system, multi-amplified with TH quattro on TW and MID, TH due on WF and TH uno on SUB, in default setting if you recall memory 1 all of the TH's would work in Hi-AB Class mode. It is possible to create custom memories, see for instance the example below, to store in memory 1 a system especially designed to ensure top quality for each way or to store in memory 2 a system especially designed for the best power/quality ratio, to store in memory 3 a system set to obtain maximum quality and in memory 4 a system best optimizing the current consumption.

ASC - Amplifier Status Controller

Runtime Monitor

This function of the ASC provides the ability to alternately show on the amplifier display the information on its operational status. Through this setup you can select the fields you want to be visible when the amplifier is on. For each field you can select YES to have the entry show on the display. If all NO are selected, the display will always show the default display screen. You will only have to select even just one entry to see it appear alternately on the display while the amplifier is working. By default all the fields are pre-set on NO.

6 / 7 • AMPLIFIER STATUS: This section is the real monitor of the amplifier's vital functions.
8 • SYSTEM AMPLITUDE SETUP: This function enables the input sensitivity of the amplifiers in the system.
9 • SYSTEM DUAL POWER SETUP: This function enables the function setting of all the amplifiers in the system.
10 • SYSTEM SETUP LOAD/SAVE: It guarantees the saving of the whole system setup or the loading of setups previously saved.

ACNet - Audison Control Network System Display

When installing a system composed by TH amplifiers it's possible to create a network between them by using ACLink series connection.

It is fundamental that a different ADRS starting from zero is assigned to each amplifier (see page 18).

In this way, when the software is turned on, the system will be able to automatically recognize which amplifier is present in the network.

This display will show all the "linked" amplifiers creating an icon corresponding to the model, the model name and the ADRS set during the installation.

The ACNet software allows the user to work either on one single amplifier or on the whole system.

In order to understand the use of the software we will work on a three way system + sub, multi-amplified, using a TH quattro on Tweeter and Midrange, TH due on Woofer and TH uno on Subwoofer.

For example, to work on a TH due double click on its dedicated icon. The name will be highlighted and its corresponding data will be displayed in the specific fields.

As for the ASC Setup Amplifier, it is necessary to set the system whenever wanting to use the digital input. In this area it is necessary to select the Main Signal Input for each amplifier connected to the system Example:

• If the amplifier being set is the first of the network to receive the signal from an external source, it is necessary to specify if it is an analog or digital one, by selecting Analog or Optical Master.
• If it is connected to both an analog and a digital source, select Optical Master and manage the sources switch through the DRC.
• If the amplifier being set receives the signal from another TH amp, connected in analog and digital AD Link, select Optical Slave.
• If the amplifier being set receives the signal from an external audio processor (Ex: Audison Bit One) select AD Link.

From this section featuring drop down menus, it is possible to regulate each amplifier's input sensitivity, acting also on the High/Low Level.

There are sliders for each channel which can work singularly or together if "linked". The software enables the fine tuning between right and left, acting on the corresponding slider. The software will show the level measured in V.

The LED Clip flashes when the max level is reached during tuning or playing.

When using a non-TH amplifier to be controlled by DRC, an ID must be assigned to the Pre Out where it is connected. In this way it is still possible to manage the TH Preout sensitivity.

The specific sliders will come into view only when a name which is not TH Amp is given to the active field.

In this section the TH amps operating modes memories can be selected.

The available preset are: Hi-AB Class (default), Hi-Current, A-Class, Energy Saving. They can be assigned to each single memory by using the drop down menus.

The memories can be recalled through the Memory keys 1 / 2 / 3 / 4 but when ACNet software is switched off, if the DRC is not connected to the system, the function selected on Memory 1 will be operating.

TH uno and TH due can only work with one preset, while TH quattro can work with one preset on A Channels and one on B Channels.

Note: When the preset A-Class or Energy Saving is assigned to A Channels, this will be automatically applied to B Channels. Please refer to the following table:

ACNet - Audison Control Network System Audio Control

System Audio Control System Volume Sub Volume Balance -28.5 dB +3.0 dB R +0 Note: Without DRC, these controls will not operate.

These controls act on the whole system:

• System Volume: it's the main volume control of the system, the slider on Min position switches on the muting and shows "MUTE" in the specific box. The adjustment starts from -60 dB (muting) up to 0 dB Max, 0,5 dB steps.
• Sub Volume: it's the specific volume control for the subwoofer, the slider on Min position switches on the muting and shows "MUTE" in the specific box. The adjustment starts from -12 dB (muting) up to +6 dB Max, 0,5 dB steps.
• Balance: it's the control that allows the left and right balancing. When in central position (+0) the output volume between left and right it's identical. It's possible to unbalance the output volume of one channel compared to the other.
• Fader: t's the control that allows the Front and Rear balancing. When in central position (+0) the output volume between Front and Rear it's identical. It's possible to unbalance the output volume of one zone compared to the other.

The Amp ID of each single amplifier inside the system must be set correctly in order to operate the audio controls. The Sub Volume control, for example, will only operate on the amplifiers identified on the Amp ID as Subwoofer. The Balance control will operate on all the amplifiers characterized by the presence of a right and left channel (it will not operate on Central and Subwoofer).

The note warns that if the DRC is not connected to the system, when ACNet software is switched off, these controls will not operate.
