M2500 Mixing ConsoleWhen discerning sound-reinforcement professionals think, "console" they also think "Yamaha." And with good reason. Yamaha sound-reinforcement consoles have, for many years been standards by which others are judged. Yamaha's new M2500 consoles up the ante once more, defining new levels of performance, control, versatility, and reliability for an industry that never stands still. Innovative features such as the group/aux flip function and LCR panning offer unprecedented control, while no-compromise circuit design, layout, and component selection from the critical head amplifiers right through to the output connectors ensure that you get the cleanest, most accurate signal possible. The most important and in-demand features have all been implemented as well: 4-band EQ with two sweepable mid-bands on all mono inputs, a matrix submix of the group auxiliary, stereo and mono/center busses as well as the sub inputs, 128-scene memory, 100 millimeter faders, and more.Group/Aux Flip FunctionThis innovative feature makes it possible to flip the functions of the group master 1 through 8 controls (including pan pots, assign switches, and insert I/O jacks) with aux send controls 7 through 14 via a single switch. When the GROUP/AUX FLIP switch is set to GROUP, the 100-mm group master faders and related controls function in the normal way, affecting the signal fed to the console's group outputs - the ideal configuration for most house mixing applications. When the GROUP/AUX FLIP switch is set to AUX, however, the group master faders are flipped with rotary aux sends 7 through 14, so that all of the console's master aux sends are controlled via full-length faders for unmatched monitor mixing convenience.Switchable LR and LCR Panning ModesAll of the mono inputs and group master controls feature LCR switches which, when engaged, assign the related panpot to the left right, and center busses for LCR panning rather than just to the left and right busses as for standard LR stereo panning. When a channel's LCR switch is not engaged, the corresponding PAN control functions normally, panning the signal from left to right on the stereo buss. When an LCR switch is engaged, the center panpot position directly feeds the channel signal to the MONO/C buss which can feed a center amp/speaker system while intermediate pan positions feed both the L or R and C buss proportionately. The centered signals are heard precisely in the center of the sound field, regardless of listening position - an ideal situation for vocals, speech, etc. (while intermediate pan positions feed both the L or R and C buss proportionately.) Intermediate pan pot positions pan between L and C when left of center and C and R when positioned right of center.INPUT CHANNELSInputsThe mono input channels feature balanced XLR-type microphone/line inputs. +48V Phantom power is independently switchable for all mono inputs, providing direct compatibility with high-performance phantom-powered condenser microphones and DI boxes. Stereo line sources can be directly connected to either of 4 stereo input channels (a total of eight inputs). Stereo channel 1 has switchable "A" or "B" inputs: the "A" inputs are balanced XLR type connectors, and the "B" inputs are standard RCA pin jacks type for compatibility with the widest possible range of line sources. Stereo channels 2 through 4 have balanced TRS inputs.Channel InsertionInsert send/return patch points are included on all mono channels for convenient insertion of compressor/limiters (a must for top-quality vocal sound), equalizers, or any other outboard equipment you might need to apply to individual channels.Input Controls and Level MatchingGain trim controls with a 44-dB range on all mono inputs, independent 40-dB gain controls for the A input on stereo channel 1 and stereo channels 2 through 4, and a 30-dB gain controls for the B input on stereo channel, facilitate optimum level matching with a wide range of sources. The mono inputs additionally feature 26-dB pad switches and phase switches for easy input phase correction.Filters and Flexible 4-band Channel EQAll mono channels features switchable high-pass filters to effectively eliminate rumble and other low-frequency noise. The mono channels also feature a very flexible 4-band equalizer which provides sweepable frequencies for the HI MID and LO MID bands. The stereo channels offer 2-band shelving EQ. EQ bypass switches are provided on all channels so equalization can be punched in or out as required without having to change settings.14 Aux SendsThe AUX 1 through AUX 14 controls are mono auxiliary sends, feeding the corresponding auxiliary busses. The AUX 7 through AUX 14 signals can be re-routed to the group master controls, as described in the "25 Output Busses with Flippable Group/Aux Controls" section, above. AUX 1 and AUX 2 are hard-wired pre-fader, while the remaining 12 sends can be switched to receive the pre- or post-fader signal in groups of four.Buss Assign and Pan/Balance ControlsAll mono and stereo channels have odd/even assign switches for the 8 group busses, as well as stereo and mono buss assign switches. The mono channels have PAN controls switchable for LR or LCR operation (LCR panning mode switches and indicators - described in more detail above - are provided on all mono input channels), and the stereo channels have balance controls.3-point Level IndicatorsAll mono and stereo channels feature 3-point level indicators for accurate monitoring of pre-fader signal levels. SIGNAL, NOM (nominal), and PEAK LEDs provide a broader "view" of channel signal levels than the usual one- or two-LED indicators.Channel Faders, Pre-fader Listen, and Channel ON SwitchesSmooth, noise-free 100-mm linear faders make it easy to set up the optimum balance between channels, while PFL (Pre-Fader Listen) switches allow convenient solo monitoring of the channel's pre-fader signal. All channels additionally feature ON/EDIT switches and indicators that can be used to switch the channel signal into or out of the mix - allowing editing of mute scenes, for example - without changing any other settings.MASTER CONTROLS:Master Auxiliary SendsMaster auxiliary sends 1 through 6 feature full-length 100-millimeter faders with ON and AFL switches, and these directly feed the corresponding AUX outputs. Master auxiliary sends 7 -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 ControlsAll 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 SwitchFlips the functions of the master group controls (1 through 8) with aux send masters 7 through 14. This makes it possible to instantaneously optimize the master control section for main or monitor mixing applications.All Balance Outputs with Insert PatchingAll 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 InputsSub 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 and 8 Mute GroupsUp to 128 mute "scenes" can be stored in memory and recalled either via the panel controls or an external MIDI device. 8 DIRECT RECALL switches can be used for instant recall of the most often-used scenes, while others can be recalled via the numeric keys. Also 8 DIRECT RECALL switches can alternatively be used as 8 Mute Group switches. The memory contents can be checked and edited at any time without actually affecting the mix.In addition to recalling complete scenes, the external MIDI control can be used to individually turn the applicable channels and busses off or on as required. A MIDI sequencer or computer 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 processors so that appropriate effects are recalled automatically. Furthermore, scene data can be dumped to a MIDI data record or other storage device for long-term storage.Submix MatrixThe 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 and MeteringIn 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 ModuleFor 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 100zm 1kHz, 10kHz and pink noise output.Lamp ConnectorsConnectors for up to three Yamaha LA1800 (option) console lamps are provided on the rear panel.Power SupplyA newly developed, high-performance PW3000MA power supply includes full power monitoring, and for extra reliability 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.
