These jacks output the signal before or after the faders for the various buses. The PFL/AFL indicator (4) and the PFL and AFL indicators in each section indicate which signal is being output. NOTE · If both a PFL switch and AFL switch are on, the PFL switch will be enabled. If you want to monitor the signals after the faders, turn off all PFL switches. 2 PHONES Jack Connects a pair of headphones to this stereo phonetype output jack. These jacks output the signal before or after the faders for the various buses. 3 MONITOR Level Meter Indicates the level of the signal output to the MONITOR OUT and PHONES jacks. The “0” segment indicates the nominal output level. The PEAK segment lights red when the output approaches the clipping level. 4 PFL/AFL Indicator Indicates the signal sent to the MONITOR OUT and PHONES jacks. The PFL indicator will light when the signals before the faders (control) are being sent; the AFL indicator will light if the signals after the faders are being sent. 5 MONITOR Control Controls the level of the signal output to the MONITOR OUT jacks. 6 PHONES Control Controls the level of the signal output to the PHONES jack.

You can connect a graphic equalizer or other signal processor. This is a TRS (tip, ring, sleeve) phone jack that carries both the send and return signal (tip = send/out; ring = return/in; sleeve = ground). NOTE · Patching external devices via an INSERT jack requires a special insert cable such as illustrated below (insert cable sold separately).

The “-20” LED will light if the output signal level reaches -20 dB, and the “0” LED will light at nominal level. The PEAK LED will light red when the MONO OUT signal reaches 3 dB before clipping. 5AFL Switch/Indicator When the AFL switch is on, the indicator will light and the signal after the MONO fader is output to the MONITOR OUT and PHONES jacks for monitoring. NOTE · If you want to monitor the signal after the MONO fader, turn off all PFL switches. 6MONO Fader Controls the level of the signal output to the MONO jack. LAMP Connector This is an XLR-4-31 type connector that supplies power to a separately sold gooseneck lamp (e.g., Yamaha LA5000). The IM8-40 mixer has three of these connectors, and the IM8-32/24 mixers have two. Impedance balanced: Since the hot and cold terminals of impedance balanced output jacks have the same output impedance, these output jacks are less affected by induced noise. English Owner’s Manual 19 Troubleshooting Troubleshootingg English Power doesn’t come on. • Is the dedicated PW8 power supply properly plugged into an appropriate AC power outlet? • Is the dedicated PW8 power supply properly connected using the included power supply cable? The PW8 itself will not power-on unless it is correctly connected via the included power cable. • If the above checks do not identify the problem, call Yamaha for service. The sound of the bass drum will not move forward in the mix. • Could you be mixing a phase-reversed signal? Try turning on the switch to reverse the phase. If you are capturing the sound using multiple mics, phase reversal may be causing cancellation. How can I send the pre-EQ signal to an AUX bus for monitoring? • You can send the pre-EQ signal to an AUX bus by changing an internal jumper setting. Turn the AUX PRE switch on (pre-fader). In this case, the signal will be sent to the AUX bus even if the input channel’s ON switch is off. How can I monitor the signal of a GROUP bus before I send it to the ST L/R bus? • With the GROUP section ON switch turned off, turning the GROUP section AFL switch on will let you monitor the AFL signal of the GROUP bus without sending it to the ST L/R (and MONO) bus. How can I send a compressed signal to the ST L/R bus while sending the uncompressed signal to DIRECT OUT jacks for recording? • If you connect a compressor (external device) to the INSERT jacks and apply compression to the signal being sent to the ST L/R bus, the signal before the compressor will be sent to the DIRECT OUT jacks. In this case, turn off the IM8’s COMP control. How can I send the TALKBACK signal only to the intercom? • In the TALKBACK section, turn on only MATRIX 1-2 (or MATRIX 3-4) to send the output of MATRIX...
