Thank you for purchasing the Mach M20.04 digital system controller from Mach Speakers A/S. Every effort has been made to ensure that our products meet your requirements and we sincerely hope that we will live up to your expectations.
The Mach M20.04 has been designed for superior audio quality and flexible system configuration and is intended to optimize the performance of Mach loudspeaker systems.
The Mach M20.04 is a compact and powerful DSP-based audio-processing unit capable of operating the speakers in the Mach product range that require or benefit from the use of a system controller. It is ideal for fixed installations and live applications as it combines the functions of multiple conventional products in a compact 1 U of rack space.
The Mach M20.04 has two balanced XLR analog Inputs, a digital Input at 44.1 or 48 kHz, and four balanced XLR analogue outputs. It is supplied pre-loaded with the most common configurations of our product range. Furthermore, 100 "user presets" are available for other loudspeaker combinations, which may be required for certain applications.
This manual contains technical specifications and describes how to configure the Mach M20.04 to suit your specific application and achieve the best possible performance from the unit.
The MACH M20.04 incorporates the following fully configurable features:
• Each Input has gain control and 4 bands of Parametric EQ. Bands 1 & 4 can be set for LF & HF shelving response.
- Routing section - The signals present on Inputs A & B can be routed to any of the four Output channels
- Crossovers on each Output channel - Variable high and low pass filters for each output can be set with a choice of classic filters. Independent control over high pass and low pass functions allow asymmetric crossover functions to be used.
- Four band parametric EQ on each Output
- Four independent Delay lines (up to 200ms)
- Four high performance Limiters, featuring a wide range of control over Attack, Release & Threshold parameters.
- Output Gain adjustment
FRONT PANEL OVERVIEW
1 POWER On/Off
The MACH M20.04 uses a switchmode power-supply that accepts from 100-240V AC.
2 INPUT METERS
For optimal performance the Input level indication should be around -5dB and occasionally peak at 0dB. If the CLIP indicator is lit the Input signal is too hot. Input sensitivity can be set in the Level menus accessed via the INPUT A/B keys, or via the Setup menu.
3 DISPLAY
32 character LCD displaying various operating parameters.
4 DIGITAL IN select
Press the DIGITAL IN key and the MACH M20.04 will try to lock to the Digital Input. If a valid digital clock is present on the Input the unit will automatically use the digital signal as Input source. Press once more to release and switch to analog Inputs.
5 INPUT A/B
On/Off switches for the two channels. For the signal to pass further down the signal chain the key LEDs must be lit.
In Edit mode these switches give access to the Input Trim parameter for each channel.

Use the four switches in column A to send the signal from Input channel A to any of the four Outputs.
Use the four switches in column B to send the signal from Input channel B to any of the four Outputs.
8 X-OVER keys
On/Off switches for the X-Overs.
In Edit mode these keys give access to edit X-Over settings.

Recall
To recall a preset
- Press RECALL
- Select preset using the ADJUST encoder
- Press ENTER
Reduce volume before recalling presets. Recalling a new preset may cause radical changes to both gain and routing settings.
Store
100 locations are available for user presets.
To store a preset
1 Press STORE
2 If the currently recalled preset is a User preset the same user location is suggested.
- If the currently recalled preset is a factory preset, the first free user location is suggested.
- If you wish to store the preset at a different location - select the desired user location using the ADJUST encoder.
3 Press ENTER.
4 Now you may;
- either press ENTER again to confirm and end the store operation
- or dial in a preset name of your choice using the CURSOR keys and ADJUST encoder and then press ENTER.
5 The display indicates "Preset Stored" for a successful store operation.
The Setup menu
The Setup menu holds various overall setup parameters.
Output Range
Range: 2, 8 (consum), 14, 20(pro) dBu. The Output range should match the Input sensitivity of your downstream device/amplifier. Please refer to the manual of that device.
Input Sensitivity
Range: 0 to 24dBu
The Input range should match the Output range of your feeding device. Please refer to the manual of that device or adjust according to the Input meters.
Delay Unit
The Delay time can be displayed in milliseconds, meters or feet.
Lock Function - introduction
As a speaker management controller is a key component in speaker setups a lock function is provided to prevent unintended change of parameters via the frontpanel.
Setting up the LOCK function is done via the Setup menu.
There are two basic Lock modes
- one mode where the frontpanel is unlocked simply by pressing the LOCK key once.
- another mode where you need to press LOCK and then dial in the “security code” followed by ENTER in order to unlock the function keys. The code is set via the Setup menu.
Timing function
A timing function can be set for both Lock modes allowing the front panel keys to be unlocked for either: 10, 30 or 60 seconds.
Range: Off, 10 seconds, 30 seconds, 60 seconds
Lock Code
Range: 0000-9999
"0000" is "no lock code" and the front panel keys can be locked/unlocked simply by using the LOCK key.
The following section takes a look at the processing chain following the front panel layout from left to right. On the front panel this is called the "Schematic Section"
Digital In
The MACH M20.04 accepts digital Input at 44.1 or 48kHz. Per default the MACH M20.04 is set to analog Inputs.
To switch to the digital Inputs.
- Be sure that a valid digital Input signal is present in the DIGITAL IN connection.
- Press the DIGITAL IN key. Analog Inputs are muted and the key LED will flash until lock is achieved.
• To return to Analog Inputs - press once more.
Input Bypass A/B - Input Trim
Signal from the two Inputs A and B will be passed to the Routing section if the LEDs in the two INPUT keys are lit.
- Press to activate/deactivate.
Input Trim
In Edit mode you have access to individual Input trim parameters on channels A and B.
Parametric EQ (Input EQ)
The Controller holds two parametric EQ sections. The first is located on the Input side of the Routing matrix. One for channel A and one for channel B.
| Par EQ A, B Type: Gain Freq: Width/Slope: | |
| Band 1 Lo Shelve 20 Hz – 20 kHz 6dB/OctHi Pass 20 Hz – 20 kHz 12dB/OctPar EQ ±18 dB 20 Hz – 20 kHz 0,03 – 4 Oct | |

The Routing section is the "railway-station" in the signal chain. The signal present on Inputs A/B can via the 2x4 select switches be routed to none, any or all of the four Output channels.
From the Routing section out the four channels are individually processed with separate X-Over, EQ, Delay, Limiter and Output blocks.
Notice that the front panel layout is identical to the actual signal flow through the unit.
Example:
Input A distributed to Output 1 and 2 Input B distributed to Output 3 and 4
A typical example of a stereo setup with split in both sides.
More examples on pages 10 to 13.
X-Over
For optimal settings please refer to your speaker specifications.
The MACH M20.04 may hold presets that perfectly match your speaker configuration.

Delay for each speaker Line. Especially for compensating for speaker placement.
Range: 0 to 200ms
Limiter
A Limiter for each speaker line is available.
Correctly set the Limiter will prevent peaks from damaging your speakers.
Threshold
Range: -40 to 0 dB
Sets the Threshold/activation point for the Limiter.
Ratio
Range: Off to Infinity
Sets the amount of attenuation.
Attack
Range: 1 to 100ms
The Attack time is the time it takes for the Limiter to reach the gain-reduction specified by the Ratio parameter.
Release
Range: 100ms to 7 sec.
Sets the time it will take for the Limiter to release the attenuation of the signal.
Output
Range: 6; 12; 18; 22dBu
It is important that the Controller Outputs are correctly matched to the Input range of your amplifier. Please refer to your amplifiers manual for correct settings.
