Page 5: Introduction
NTRODUCTION Thank you for selecting the Mar tin M20.06 Controller. The M20.06 Controller is a one unit loudspeaker management system, capable of operating all speakers in the Mach product range. This digital circuitry is based on BSS OMNIDRIVE™ DSP technology and comes equipped with 24-bit A-D and D-A converters. -
Page 6: Compliance
Compliance The M20.06 has been tested and found to comply with the following European and international Standards for Electromagnetic Compatibility and Electrical Safety: EN55013 (1990)Associated Equipment Radiated Emissions (EU) EN50082/1 (1992)RF Immunity, Fast RF Immunity (EU) Transients ESD EN61000/3/2 (1995) -
Page 7: Quick Start
UICK START 1 - Connect AC po wer The M20.06 has a universal voltage AC Power input. Connect the unit to AC Power with the lead supplied. It will switch on automatically (there is no separate on/off switch). The display will show the default screen, with the name and program number of the current program. - Page 8 For optimizing the system with regard to gain and time alignment between subwoofers and top boxes, the SIA Smaart Live program is very useful. If you use SmaartLive, you can download some Smaart starting point set-ups from the following Internet address and save them on the M20.06: http://www.mach.dk/accessories/SmaartLive_M20.06_settings.zip Quick start...

Page 9: Installation
The incoming mains power is fused within the M20.06 by the fuse holder mounted on the rear panel. Always replace with an identical 20mm x 5mm 'T' fuse, rated at 1A for continued protection from equipment damage and fire. -
Page 10: Mains Power Connection
A vertical rack space of 1U (1¾" / 44.5 mm high) is required. Ventilation gaps are unnecessary. If the M20.06 is likely to undergo extreme vibration through extensive road trucking and touring, it is advisable to support the unit at the rear and/or sides to lessen the stress on the front mounting flange. -

PERATION The chapter describes: • “Moving about the screens” • “Utilities menu” • “Inputs menu” on page 17 • “Outputs menu” on page 17 • “EQ screens” on page 20 • “Store and recall” on page 21 After powering up, the unit performs internal checks and sets up the audio path before releasing the output mute relays. -
Page 15: Stereo Link
Dump to transfer data to another unit via MIDI ensure that both devices are set to the same MIDI channel, and connect either the MIDI OUT of the Tx device to the MIDI IN of the Rx device. Alternatively, the M20.06 can be linked via their RS232 ports. -
Page 16: Delete Program
Each unit must be set to the correct MIDI mode, from a choice of Multi, Master or PCPort on the MIDI mode screen in the Utilities menu. The MIDI mode setting for each device will depend on the protocol used and whether synchronization between the units is required. -
Page 17: Inputs Menu
I N P U T S M E N U There are two inputs available for routing to outputs plus an internal mono sum of inputs A and B, referred to as A+B. This gives the Input Channels: A, B, and A+B. The facilities described in this section are common to all inputs, except EQ, which is not possible on the mono sum A+B signal. -
Page 18: Source
stereo is NOT linked begins with L<space> or R<space>, then the L or R will not be displayed when stereo linking is on. Source To change the source input, use the Parameter UP/DOWN keys until the desired input source is selected. Ban d gai n Adjusts the output gain from -25dB to +4dB using the Parameter UP/DOWN keys. -
Page 19: Polarity
• 3-channel 2-way configuration, 1 will link to 4, 2 will link to 5 and 3 will link to Po larit y The polarity invert function allows the phase of an output to be rotated by 180 degrees. Default is un-inverted. Pushing the Parameter UP key will invert the polarity of the output. -
Page 20: Eq Screens
(See “EQ screens” on page 20 for more details). E Q S C R E E N S If the M20.06 is configured for MONO, all EQs will be mono. If configured for 2x2+1 ("stereo"), EQs will be marked as Stereo 'S' when STEREO LINK is ON, and the stereo marker will show an 'S' next to the EQ number. -

Storing and Recalling a program can be done at any time using the STORE and RECALL keys on the left hand side of the LCD. The M20.06 can hold 60 programs inter nally. To reset a unit to default values, use the configuration parameter in the Utilities screen. -

UNLOCKED?, asking whether the program should be stored with a Program lock on/off. Use the Parameter UP/DOWN keys to turn the Lock on/off, the default setting being ON. Once the Lock status is set, push the STORE key a final time to commit the program to memory. The display will now default back to the screen displayed before the STORE facility was accessed. -
Page 23: System Security
Any changes made to an audio system have the potential to be damaging, even if only accidentally made. For this reason several different security systems are built in to the M20.06 to protect the speakers. Each of the security levels locks different groups of variables away from accidental or malicious adjustment. -
