Making sure that neither core is connected to the earth terminal of the three pin plug. * This applies only to products distributed by YAMAHA KEMBLE MUSIC (U.K.) LTD. 2 Control panel Channel control section 1 Input selector This button selects the input connector for the channel. When A ( ) is selected, the input signal will be taken from the rear panel INPUT A connector (balanced XLR type). When B ( ) is selected, the input signal will be taken from the rear panel INPUT B connector (balanced phone jack). 2 PAD switch This pad switch provides 20dB of level reduction. If the input signal level is too high and the 3 GAIN control will not reduce it sufficiently, use this pad switch. 3 GAIN control According to the level of the input signal, use this knob to adjust the input to an appropriate level. The best balance of S/N and dynamic range will be achieved if you adjust the GAIN control so that the 4 peak indicator lights occasionally. If you wish to further reduce the input level, use the 2 PAD switch. 4 PEAK indicator This indicator detects peak levels after the EQ. It will light red at 3dB before clipping to warn that clipping level has nearly been reached. 5 80Hz high-pass filter switch This switch turns on/off a high-pass filter that cuts the signal below 80Hz at 12dB/octave. 6 Equalizer The equalizer section provides ±15dB of control over the high, mid and low ranges at the following frequencies. HIGH: 12kHz MID: 2.5kHz LOW: 80Hz Frequency response will be flat when the knob is at the “” position. 20 50..............100.. 200............500....1k......2k...... 5k....10k........20k FREQUENCY (Hz) +20 +15 +10 +5 0 –5 –10 –15 –20 RESPONSE (dB) 1 2 3 4 5 6 7 8 9 0 A B A 20dB PEAK –16GAIN –60 80 –15 HIGH +15 –15 +15 MID –15 LOW +15 0 10 AUX 1 0 10 AUX 2 0 AUX 310 0 10 AUX 4 L R PAN PFL POST PRE 10 5 0 5 10 15 20 30 40 00 ON 7 7 • The AUX1 and AUX2 controls are pre-fader, and the signal levels sent to the AUX 1 and 2 buses will be unaffected by the channel fader setting. • The AUX3 and AUX 4 controls are post-fader, and the signal levels sent to the AUX 3 and 3 buses will be affected by the channel fader setting. 8 PAN (panpot) control This knob assigns the signal of each channel to the STEREO L, R bus, determining the stereo position of the sound. 9 Channel ON switch When this switch is on, the signal of each channel will be sent to the STEREO L, R bus and the AUX1–4 buses. When this switch is off, the output signal to each bus will be muted completely. This switch should be turned off for unused channels. PHANTOM OFF (+48V) INPUT A 1-* INPUT B 1-* *=8,12,16,24 0 Channel PFL switch This switch allows you to monitor the pre-fader channel input signal through headphones. It is convenient to use PFL when you wish to check the sound of the input signal, or when troubleshooting a specific channel. A Channel fader This fader controls the output level of the input channel signal, determining the volume balance between channels. The channel fader should be lowered for unused channels.

When this switch is off, levels will not be displayed in the ST meters. The MONO OUT signal will be sent regardless of this switch. 2 STEREO L, R master faders These faders adjust the final level of the combined signals from all channels, and send them from the STEREO OUT connectors. The ST meters allow you to monitor the L and R outputs. 3 MONO ON switch This switch turns the MONO OUT on/off. 4 MONO AFL switch When this switch is on, the signal being output to MONO OUT can be monitored in the headphones. C 5 MONO fader D This fader adjusts the output level of the MONO OUT con- E nector. 6 AUX SEND 1–4 AFL switches 9 When you wish to monitor the output signals being sent to AUX SEND 1–4, press the appropriate switch. 0 The level of the AUX SEND whose switch is on will be indicated by the PFL/AFL meter. 7 AUX SEND faders A These faders adjust the level of the output signals sent from AUX SEND 1–4. The 8 METER SELECT switch can be set so that these AUX SEND signals are monitored in the level meters. 8 AUX RETURN 1, 2 controls
