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. Our explanation here will be based on stereo input channel 1, and any differences for stereo input channels 2–4 will be explained later. AGAIN A control This adjusts the input sensitivity of the signal that is input from the XLR connectors of the ST CH 1 INPUT A jacks (page 26). Levels of +10 dB to –30 dB are supported. If the A/B select switch (3) is in the B ( ) position, this control will have no effect. B GAIN B control This adjusts the input sensitivity of the signal that is input from the RCA phono connectors of the ST CH 1 INPUT B jacks (page 26). Levels of +10 dB to –20 dB are supported. If the A/B select switch (3) is in the A ( ) position, this control will have no effect. C A/B switch This selects the input jacks that will be used for stereo input channel 1. When the switch is in the upward position ( ), the ST CH 1 INPUT A jacks can be used. When the switch is in the downward position 8 ( ), the ST CH 1 INPUT B jacks can be used. Note: Since stereo input channels 2–4 have only one set of inputs, only one GAIN control is pro vided. (Nor is there an A/B select switch.) This control will adjust the input sensitivity of the signal that is input from the TRS phone connectors for the ST CH 2–4 INPUT jacks (page 26). Levels of +10 dB to –30 dB are supported. 9 J GAIN K +10 –30 D EQ controls This is a two-band equalizer. The equalizer type, center frequency, and gain range of each band is shown below. M Band Type Center frequency Gain HIGH 10 kHz ±15 dB LOW Shelving 100 Hz 6 M2500—Owner’s Manual 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. For AUX buses 3–14, the PRE switch (7) can be used to switch the signal pre or post fader. G PRE switches If these switches are turned on ( ), the pre-fader signal will be sent to the corresponding AUX buses. If these switches are turned off ( ), the post-fader signal will be sent. Switches are provided to independently switch three groups of AUX buses: 3–6, 7–10, and 11–14. H BAL control This adjusts the level balance of the signal that is sent to the STEREO or GROUP buses. If the ST switch is on The BAL control will adjust the L/R balance at which the signal of the stereo input channel is sent to the STEREO bus. If a 1-2/3-4/5-6/7-8 switch is on The BAL control will adjust the balance of the stereo input channel that is sent to the odd-numbered channels (1/3/5/7) and even-numbered channels (2/ 4/6/8) of the corresponding GROUP bus (1-2/3-4/56/ 7-8). The L ch of the input signal will be sent to the odd-numbered channel of the group bus, and the R channel of the input signal will be sent to the even- numbered channel of the group bus. I Channel assign switches These switches assign the signal that has passed through the fader and BAL control to the desired bus(es). Any or all of the channel assign switches can be used simultaneously. • 1-2/3-4/5-6/7-8 switches When these switches are on ( ), the signal of the stereo input channel will be sent to the corresponding GROUP bus (1-2/3-4/5-6/7-8). • ST (stereo) switch When this switch is on ( ), the signal of the stereo input channel will be sent to the STEREO bus. • MONO (monaural) switch When this switch is on ( ), the L and R channels of the input signal will be mixed to monaural, and sent to the MONO/C bus. The signal that is sent to the MONO/C bus is not affected by the BAL control. J ON/EDIT switch / ON, CHECK indicators The function of this switch and these indicators will change depending on the mode of the M2500. In normal mode You can use the ON/EDIT switch to turn the stereo input channel on/off. When t...
