Frequently Asked Questions - Match UP 1FX Audiotec Fischer

How do I adjust the input voltage range on the Match UP 1FX?

You can adjust the input voltage range by opening the amplifier (remove side panel with remote input). Locate the jumper and move it to either Low Voltage Range (RCA: 0.5-3V, HLI: 3-16V) or High Voltage Range (RCA: 1-6V, HLI: 6-32V) depending on your signal source output voltage.

What is the DirectDSP function and how do I use it?

DirectDSP bypasses the internal crossover, passing the signal unfiltered to the output. Set the X-Over switch to DirectDSP if you are using an external DSP or DSP amplifier for crossover control. When set to Bandpass, the internal crossover is active with a 15 Hz subsonic filter and adjustable lowpass (50-250 Hz).

Can I use both RCA and highlevel inputs simultaneously?

No. It is strictly forbidden to use the Highlevel and lowlevel Line Input at the same time as this may cause severe damage to the signal source. Choose one input type.

How do I connect the highlevel speaker inputs without a remote turn-on wire?

The Match UP 1FX features ADEP.3 technology. When using the highlevel inputs, the amplifier automatically turns on when a speaker signal is detected, so the REM (remote) input does not need to be connected.

What does the Status LED indicate?

The Status LED shows: Green = amplifier is ready; Orange = short circuit or faulty connection at speaker output; Red = Protection Mode active (over/undervoltage, overheating, or malfunction). If red, check connections or let it cool down.

How do I properly set the gain (input sensitivity)?

Set your radio to 90% max volume with a test tone (e.g., pink noise). Turn the Gain Control clockwise until the Clipping LED lights up, then turn it back counterclockwise until the LED turns off. This ensures optimal signal quality without distortion.

What is the minimum speaker impedance the amplifier can handle?

The amplifier is stable down to 1 Ohm. At 1 Ohm it delivers 900 Watts RMS. Do not connect loads below 1 Ohm as it will trigger protection. For dual voice coil subwoofers, you can wire coils in series or parallel to achieve the desired impedance.

Can I use a remote control with the Match UP 1FX?

Yes, the amplifier has a Remote Control Input (3.5mm jack) for an optional remote control (sold separately). This allows you to adjust the subwoofer volume from the driver's seat.

What should I do if the Fuse LED lights up red?

If the Fuse LED is red, the internal fuses are blown. Replace them only with identically rated fuses (2 x 30 A LP-Mini-fuse (APS)). Using higher-rated fuses can cause dangerous damage.

Does the amplifier have a warranty and what does it cover?

The warranty is based on statutory regulations. It covers manufacturing defects but excludes damage from overload or improper handling. Returns require prior consultation, original packaging, a detailed error description, and proof of purchase.

General instructions

General installation instructions for MATCH components

To prevent damage to the unit and possible injury, read this manual carefully and follow all installation instructions. This product has been checked for proper function prior to shipping and is guaranteed against manufacturing defects.

Before starting your installation, disconnect the battery's negative terminal to prevent damage to the unit, fire and / or risk of injury. For a proper performance and to ensure full warranty coverage, we strongly recommend to get this product installed by an authorized MATCH dealer.

Install your UP 1FX in a dry location with sufficient air circulation for proper cooling of the equipment.

For safety reasons, the UP 1FX must be professionally installed. Therefore, use the two mounting plates which are included in delivery. These are attached to the bottom of the amplifier with two short screws which are included in delivery, too.

When screwing the amplifier to the vehicle chassis, carefully examine the area around and behind the proposed installation location to ensure that there are no electrical cables or components, hydraulic brake lines or any part of the fuel tank located behind the mounting surface. Failure to do so may result in unpredictable damage to these components and possible costly repairs to the vehicle.

General instruction for connecting the UP 1FX amplifier

The UP 1FX amplifier may only be installed in motor vehicles which have a 12 Volts negative terminal connected to the chassis ground. Any other system could cause damage to the amplifier and the electrical system of the vehicle.

The positive cable from the battery for the entire sound system should be provided with a main fuse at a distance of max. 30 cm from the battery. The value of the fuse is calculated from the maximum total current draw of the car audio system.

Use only suitable cables with sufficient cable cross-section for the connection of the UP 1FX. The fuses of the amplifier may only be replaced by identically rated fuses (2 x 30 A) to avoid damage of the amplifier.

Prior to installation, plan the wire routing to avoid any possible damage to the wire harness. All cabling should be protected against possible crushing or pinching hazards. Also avoid routing cables close to potential noise sources such as electric motors, high power accessories and other vehicle harnesses.

Configure the MATCH UP 1FX as follows

Caution: Carrying out the following steps will require special tools and technical knowledge. In order to avoid connection mistakes and / or damage, ask your dealer for assistance if you have any questions and follow all instructions in this manual (see page 11). It is recommended that this unit will be installed by an authorized MATCH dealer.

1. Adjusting input voltage range

Before proceeding to adjust the input voltage range, please take note of the following guidelines. This adjustment is only necessary when connecting devices from the following categories:

• Aftermarket radios with an output voltage exceeding 3 V RMS
• Premium sound system amplifiers with an output power of more than 50 W RMS
• Stand-alone DSPs with an output voltage exceeding 3 V RMS

For standard applications, such as connecting:

• Audiotec Fischer DSP amplifiers using RCA cables
• Factory radios
• Aftermarket radios with an output voltage of less than 3 V RMS

this adjustment is not required. In such cases, you can proceed directly to page 14, point 2.

To set the input voltage range, follow these steps:

a. Open the amplifier

Remove the side panel with the remote control input by loosening the three Allen screws and sliding out the bottom panel to the side.

b. Determine the output voltage of the signal source

We recommend measuring the maximum output voltage using an appropriate measuring device or contacting your authorized MATCH dealer. If you are unsure, we recommend setting the jumper to the „High Voltage Range“ (Cinch 1 - 6 V / Highlevel 5 - 32 V) to

avoid potential damage to the device. To do this, the jumper must be moved to the factory-unused multi-pin connector, as shown in figure 2.

c. Place the jumper in the corresponding voltage range

To change the position of the jumper, simply lift it upwards and insert it into the desired position. Ensure that the jumper is fully inserted and not offset.

Overview of jumper positions:

Low voltage range configuration ( by default / see fig. 1):

Value range: HLI (Highlevel) 3 - 16 Volts RCA /Cinch 0.5 - 3 Volts

High voltage range configuration (see fig.2):

Value range: HLI (Highlevel) 6 - 32 Volts RCA / Cinch 1 - 6 Volts

d. Reassemble the amplifier

2. Connecting the pre-amplifier input

The lowlevel line input can be connected to signal sources such as head units, radios, DSPs and DSP amplifiers using appropriate cables. The input sensitivity can be optimally adapted to the signal source using the gain control (see page 15, point 6).

Important: It is strictly forbidden to use the Highlevel and lowlevel Line Input at the same time as this may cause severe damage to the signal source.

3. Connecting the highlevel speaker inputs

The highlevel loudspeaker inputs A and B can be connected directly to the loudspeaker outputs of the signal source (e.g., head units, radios, DSPs, DSP amplifiers) using appropriate cables (loudspeaker cables with 1 mm^2 / AWG 18 max. ).

The Highlevel Input is equipped with our proprietary ADEP.3 circuit (Advanced Diagnostics Error Protection 3rd generation) which ensures that the car radio detects the amplifier as a speaker and thus neither any function of the radio (e.g. fader) will be deactivated nor any error log in the CPU of the car will be created. If this input is used, the remote input (REM) does not need to be connected, as the amplifier will automatically turn on once a loudspeaker signal is applied.

Attention: Solely use the pluggable screw-terminal for the highlevel connector included in the delivery!

Important: It is strictly forbidden to use the Highlevel and lowlevel Line Input at the same time as this may cause severe damage to the signal source.

4. Adjusting the filter mode of the internal crossover

The UP 1FX is equipped with a DirectDSP function, which allows you to bypass the internal crossover. You can activate or deactivate this function using the X-Over switch (see page 12, point 1).

DirectDSP: In this mode, the internal crossover is deactivated, and the input signal is passed unfiltered to the output stages of the amplifier.

Bandpass: When the switch is set to this position, the internal crossover is active, and a 15 Hz highpass filter (Subsonic) is always active. This means a bandpass is created. By using the lowpass filter control (LPF, page 12, point 2) the bandpass can be adjusted between 50 Hz and 250 Hz.

5. Connection to power supply & remote Make sure to disconnect the battery before installing the MATCH UP 1FX!

Ensure correct polarity.

+12 V: Connector for the positive cable.

Connect the +12 V power cable to the positive terminal of the battery. The positive wire from the battery to the amplifiers power terminal needs to have an inline fuse at a distance of no more than 12 inches (30 cm) from the battery. The value of the fuse is calculated from the maximum total current input of the whole car audio system (UP 1FX = max. 60 A RMS at 12 V RMS power supply). If your power wires are short (less than 1 m / 40") then a wire gauge of 16 mm² / AWG 6 will be sufficient. In all other cases we strongly recommend gauges of 25 - 35 mm² / AWG 4 - 2!

GND: Connector for the ground cable. The ground wire should be connected to a common ground reference point (this is located where the negative terminal of the battery is grounded to the metal body of the vehicle) or to a prepared metal location on the vehicle chassis, i.e., an area cleaned of all paint residues. The cable should have the same gauge as the +12 V wire. Inadequate grounding causes audible interference and malfunctions.

REM: The remote input is used to switch on and off the UP 1FX. It is mandatory to connect this in put to the remote output of the preconnected device that provides the input signal to the UP 1FX.

This input does not need to be assigned if the highlevel input is used.

We do not recommend controlling the remote input via the ignition switch to avoid pop noise during turn on / off.

6. Adjustment of the input sensitivity

ATTENTION: It is mandatory to properly adapt the input sensitivity of the UP 1FX to the signal source to achieve the best possible signal quality and avoid damage to the amplifier. It is also mandatory to adjust the "Voltage Range" to the output voltage of your signal source (see page 13, point 1).

The input sensitivity can be optimally adapted to the signal source using the gain control (page 12, point 5).

This is not a volume control; it's only for adjusting the amplifier gain. The setting of the control affects both the Highlevel and lowlevel Line Input.

Input sensitivity is factory set to 16 Volts (high-level) and 3 Volts (RCA / Cinch). This is definitely the best setting in most applications.

The Gain control ranges are:

Low Voltage Range configuration:

Highlevel: 3 - 16 Volts

RCA / Cinch: 0.5 - 3 Volts

High Voltage Range configuration:

Highlevel: 6 - 32 Volts

RCA / Cinch: 1 - 6 Volts

If the signal source provides a lower output voltage, the input sensitivity can be smoothly increased via the Gain Control.

If your signal source delivers a higher output voltage – for example, if a factory-installed amplifier serves as a signal source – the input sensitivity must be lowered via the control, and

the correct configuration of the "Voltage Range" jumper must be checked.

If you are not sure regarding the signal source's output voltage, please contact your MATCH specialist dealer.

The Clipping LED (see page 12, point 4) serves as monitoring tool.

Note: Don't connect any loudspeakers to the outputs of the amplifier during this setup.

For adjustment please proceed as follows:

1. Turn on the amplifier.

2. Adjust the volume of your radio to approx. 90 % of the max. volume and playback an appropriate test tone, e.g., pink noise (0 dB).

3. If the Clipping LED already lights up, you have to reduce the input sensitivity via the Gain Control until the LED turns off.

4. Increase the input sensitivity by turning the Gain Control clockwise until the Clipping LED lights up. Now turn the control counterclockwise until the Clipping LED turns off again.

7. Connecting the loudspeaker outputs

The loudspeaker outputs can be connected directly to the wires of the loudspeakers. Never connect any of the loudspeaker cables with the chassis ground as this will damage your amplifier and your speakers. Ensure that the loudspeakers are correctly connected (in phase), i.e., plus to plus and minus to minus.

Exchanging plus and minus causes a total loss of bass reproduction. The plus pole is indicated on most speakers. The impedance must not be lower than 1 Ohm, otherwise, the amplifier protection will be activated. Examples for speaker configurations can be found on page 17 et sqq.

8. Filter settings

When using the DirectDSP function (see page 14, point 4), adjust crossover frequencies in the preconnected DSP or DSP amplifier. For bandpass function, use the lowpass filter control (LPF) on the device. In this case, a 15 Hz high-pass filter (subsonic) is always active.

1. Lowpass filter control (LPF)

This control allows you to adjust the lowpass filter of the bandpass between 50 Hz and 250 Hz. The control is activated when the X-Over switch is set to "Bandpass" (see page 14, point 4).

2. Remote control input

This input is used for connecting an optionally available remote control. The remote control can be used to adjust the volume of the subwoofer.

3. Clipping LED

Normally, the Clipping LED is off and only lights up if the lowlevel Line Input or one of the High-level Inputs is overdriven.

On (red): One of the analog signal inputs is overdriven. Reduce the input sensitivity using the Gain Control until the LED goes out. Instructions on how to reduce the input sensitivity are described on page 15, point 6.

4. Fuse LED

The LED indicates the status of the internal fuses.

Off: Fuses are intact.

On (red): The internal fuses are blown. They may only be replaced by identically rated fuses (2 x 30 A) to avoid damage of the amplifier.

Using higher-rated fuses can lead to dangerous consequential damage!

5. Status LED

The Status LED indicates the operating mode of the amplifier.

Green: The amplifier is ready for operation.

Orange: There is a short circuit at the speaker output or a faulty connection. In this case, check all connections for errors.

Red: Protection Mode active. A malfunction has occurred that may have different root causes. The amplifier is equipped with protection circuits against over- and undervoltage as well as overheating. Please check for connecting failures such as short-circuits or other incorrect connections. If the amplifier is overheated, the internal temperature protection will turn off the signal output until it reaches a safe temperature level again. If the amplifier does not turn on, it is defective and needs to be sent to your local authorized dealer for repair service.

Note: If you have activated the DirectDSP function, the crossover frequencies for the subsonic or lowpass must be set in the preconnected DSP / DSP amplifier.
