Yamaha mixing consoles manual PW3000MA Power Supply

■Master Auxiliary Sends

Master auxiliary sends 1 through 6 feature full-length 100-millimeter faders with ON and AFL switches, and theses directly feed the corresponding AUX outputs. Master auxiliary sends 7 through 14 are normally rotary controls with ON and AFL switches, feeding the corresponding AUX outputs, but these can be flipped with the 100-millimeter faders and related controls normally assigned to the 8 group busses.

■Group Master Controls

All 8 group master faders are full-length 100-mm types with ON/EDIT switches and indicators, AFL switches, PAN controls, MATRIX assign, STEREO assign, MONO assign, and LCR panning mode switches. These group controls, in conjunction with the flippable aux master controls, lets you configure the console to meet your group/auxiliary requirements while retaining full use of all 25 output busses.

■Group/Aux Flip Switch

Flips the functions of the master group controls (1 through 8) with aux send masters 7 through 14. This makes it possible to to instantaneously optimize the master control section for main or monitor mixing applica- tions.

■All Balance Outputs with Insert Patching

All outputs from the M2500 console — stereo, mono/center, group, aux, monitor, and matrix out — are electronically balanced for full compatibility with professional equipment and optimum performance with long signal runs. The group/aux, aux, stereo, and mono outputs also feature insert patch points for external signal processing.

■Sub Inputs

Sub inputs to the stereo L and R busses, the mono/center buss, and the submix matrix allow external line-level signals to be added to the mix as required.

■128 MIDI Scene Memory & 8 Mute Groups

In the M2500 console the channel, group/ aux, stereo, and mono/center buss mute functions are electronically controlled by a microcomputer and MIDI interface. Up to 128 mute “scenes” can be stored in memory and recalled either via the panel controls or an external MIDI device. Eight DIRECT RECALL switches can be used for instant recall of the most often-used scenes, while others can be recalled via the numeric keys. The memory contents can be checked and edited at any time without actually affecting the mix.

In addition to recalling complete scenes, external MIDI control can be used to individu- ally turn the applicable channels and busses off or on as required. A MIDI sequencer or computer, for example, could be used for complete mute automation. And since the M2500 also transmits MIDI program change messages whenever a scene is recalled, it can be linked to MIDI-controllable signal proces- sors so that appropriate effects are recalled automatically. Furthermore, scene data can be dumped to a MIDI data recorder or other storage device for long-term storage.

■Submix Matrix

The matrix mix concept was a Yamaha innovation which has virtually become an industry standard in professional audio consoles. The M2500 features a 13 x 8 matrix mix which allows the 8 group/aux buss signals,

the stereo signals, the mono buss signal, and the L and R sub input signals to be mixed to eight balanced outputs for extra stage monitor mixes, zoned speaker mixes, or just about any type of mix the job requires. All eight matrix mixes include mix on/off switches and AFL switches.

■Flexible Monitoring & Metering

In addition to balanced stereo monitor outputs, the M2500 consoles feature a balanced mono/center monitor output for an extra margin of monitoring versatility. There’s also a separate headphone output with its own level control. A L+R switch sums the left- and right-channel signals when you want to monitor in mono via the stereo monitor outputs.

A total of 11 large illuminated VU meters with built-in peak-reading LEDs provide accurate visual level monitoring. Eight of the meters can be switched to display levels on the group busses, aux busses, or the matrix outputs. The remaining three meters show levels on the stereo and mono/center busses.

■Oscillator/Talkback Module

For talkback the M2500 features a panel- mounted microphone jack with level control and on/off switch. For convenient system calibration and testing there’s even a built in oscillator with 100Hzm 1kHz, 10kHz and pink noise output.

■Lamp Connectors

Connectors for up to three Yamaha LA1800 (option) console lamps are provided on the rear panel.

PW3000MA Power Supply

A newly developed, high-performance PW3000MA power supply unit is available as an optional accessory for the M2500 mixing console. Two PW3000MA units can be parallel connected so that if one fails the other will automatically take over — with no need for any extra automatic switchover equipment.
