iv M2500—Owner’s Manual
Introduction Thank you for purchasing the Yamaha M2500 mixing console. The M2500 is a highly costeffective mixing console that features functionality such as scene memory, PAN control that is switchable between LR/LCR, and GROUP/AUX FADER FLIP switches. In order to take full advantage of the M2500’s functionality and ensure trouble-free use, please read this manual carefully. Note: • This manual assumes that you have an understanding of basic mixing console operation and terminology.
Features of the system • The M2500-24 {32/40C/48C/56C} provides 24 {32/40/48/56} monaural input modules and four stereo input modules. It also provides 14 AUX outputs, eight group outputs, stereo output, and monaural output, for a generous total of 25 output buses. The M2500 is ideal for a wide range of applications from use as a main PA mixer to use in installed systems.
Control panel A +48 V (phantom power) switch Input channel section This switches the +48 V phantom power supply on/ off for the corresponding channel. When the switch is pressed in ( ), phantom power is on. At this time the indicator above the switch will light. Monaural input channels The M2500-24 {32/40C/48C/56C} provides 24 {32/ 40/48/56} input channels. The specifications of each input channel are the same for all models of the series.
Control panel If these switches are turned on ( ), the post-EQ prefader signal will be sent to the corresponding AUX buses. If these switches are turned off ( ), the postfader signal will be sent. Switches are provided to independently switch three groups of AUX buses: 3– 6, 7–10, and 11–14. J PAN control This adjusts the pan or balance of the signal that is sent from the monaural input channel to the STEREO, MONO/C, or GROUP buses.
Control panel L ON/EDIT switch / ON, CHECK indicators M PEAK/NOM/SIGNAL indicators The function of this switch and these indicators will change depending on the mode of the M2500. These three indicators allow you to check the prefader signal level of the monaural input channel. ● In normal mode You can use the ON/EDIT switch to turn the monaural input channel on/off. When the channel is switched on/off, the ON indicator will be lit/dark to indicate the status.
Control panel Stereo input channels The M2500 provides four stereo input channels, allowing line-level stereo sources such as sub-mixers, effect processors, and CD players to be input. Of the stereo input channels 1–4, channel 1 provides both XLR and RCA phono input jacks, and you can select and use one of these. Channels 2–4 provide a pair of TRS phone input jacks. For this reason, there are slight differences between the controllers of channel 1 and channels 2–4.
Control panel E EQ switch This turns the equalizer on/off. When the switch is pressed in ( ), the equalizer is on. F AUX 1–AUX 14 controls These adjust the level at which the signal of the stereo input channel (the L/R input signals mixed to a monaural signal) is sent to the AUX buses 1–14. Placing the control at the “▲” position will produce nominal level (0 dB). For AUX buses 1/2, the pre-fader signal will be output.

Nominal output level of each jack is +4 dB. The pin wiring is as follows. These are TRS phone jacks for inserting an external effect processor into each output channel of the G1/ A7–G8/A14 section. Nominal input level is 0 dB. The pin wiring is as follows.
Rear panel L MIDI connectors These are standard five-pin MIDI connectors. By connecting these to a sequencer or to the MIDI interface of a computer, scenes can be selected from an external device, or scene memories can be backed up. ● MIDI IN connector MIDI data is received at this connector. Use a MIDI cable to connect this to the MIDI OUT connector of your external MIDI device. By connecting two PW3000MA units to the M2500 as shown in the following diagram, you can ensure a stable supply of power.
The Scene Memory function What is scene memory? Scene memory is a function that stores the on/off status of the monaural/stereo input channels, the G1/ A7–G8/14 section, the STEREO section, and the MONO/C section as one of 128 “scenes.” A scene that has been stored can be easily recalled at any time. Program change messages received at the MIDI IN connector can also recall scenes, and when a scene is recalled, a corresponding program change message can be transmitted from the MIDI OUT connector.
The Scene Memory function Operation in Normal mode Recalling a scene 1. Use the ▲/▼ switches or the 0–9/ENTER switches of the control section to make the MEMORY display show the scene memory number that you wish to recall. Using Direct Recall to recall a scene With the factory settings, you can use the DIRECT RECALL of the control section to directly recall scene memory numbers 1–8. (This is called the Direct Recall function.
The Scene Memory function 2. Use the ▲/▼ switches or the 0–9/EDIT switches to make the MEMORY display indicate the scene memory number into which you wish to store the scene. (Scene memory numbers 129 and 130 are recall-only, and cannot be selected.) 1 2 3 4 5 6 7 8 9 0 ENTER Check mode operation In Check mode, you can check the settings of a scene before recalling it, or edit the on/off settings of a scene without affecting the current on/off statuses.
The Scene Memory function 3. If you wish to actually recall the selected scene, press the RECALL switch. RECALL The scene whose on/off settings you checked will be recalled, and the M2500 will automatically return to Normal mode. If you wish to return to Normal mode without recalling the scene, press the CHECK switch once again. Note: If you press a DIRECT RECALL 1–8 switch while in Check mode, the corresponding scene memory number 1–8 will be forcibly recalled, and Check mode will also be cancelled.
The Scene Memory function Utility mode procedures In Utility mode you can make various settings related to scene memory and MIDI. In this mode you can also transmit a bulk dump to backup the entire contents of scene memory on your sequencer or computer. Basic procedure in Utility mode 1. From Normal mode, press the UTILITY switch in the control section and immediately release it. (If you press and hold the UTILITY UTILITY switch for one second or more, you will exit Utility mode and return to Normal mode.
The Scene Memory function (MIDI channel) ....................................... 1–16 (factory setting: “ ”) Select the MIDI channel that will be used when MIDI data is transmitted/received via the MIDI IN/OUT connectors. (program change transmission/reception) ... ....oFF/on/LoC (factory setting: “ ”) This specifies whether or not program change messages will be transmitted/received via the MIDI IN/ OUT connectors. • If “ ” is selected Program changes will not be transmitted or received.
The Scene Memory function Control change table The M2500 is able to receive control change messages from the MIDI IN connector to switch on/off the ON/EDIT switches of the input channels, G1/A7–G8/ A14 section, and stereo/monaural master section. When a control change number with a value in the range of “0–63” is received, the ON/EDIT switch of the corresponding channel will be turned “off,” and when a value in the range of “64–127” is received the switch will be turned “on.
The Scene Memory function Mute groups By setting the Utility mode item oP (recall operation) to “ ,” you can use the on/off settings of scene memory numbers 1–8 as “mute groups.” In this case, the DIRECT RECALL 1–8 switches will function as “mute group switches” that control mute groups. The differences in operation between the “ ” (direct recall) and “ ” (mute group) settings of the oP (recall operation) item are explained below.
The Scene Memory function Using mute groups 1. In a scene memory number 1–8, store the mute (off) settings of the channels that you wish to use as a mute group. 2. Press the UTILITY switch to move to Utility mode, select the oP (recall operation) item, and set its value to “ .” (For details on procedure in Utility mode, refer to page 34.) Now scene memory numbers 1–8 can be used as mute groups, and the DIRECT RECALL 1–8 switches will function as mute group switches. 3.
Error messages While the M2500 is being operated or when the power is turned on, the MEMORY display may show one of the following error messages. If this occurs, refer to the corresponding explanation and take appropriate action. An error occurred while receiving MIDI data. If an error occurs while receiving MIDI data, this error message will be displayed for several seconds. The voltage of the internal battery has fallen below the nominal level (2.5 V), or has become abnormal.
