Front & Rear Panels 7 SEND Jacks • AUX This is an impedance balanced phone-type output jack. This jack outputs the signals from AUX bus, respectively. You use this jack, for example, to connect to an effector or to a cue box or other such monitoring system. • EFFECT This is an impedance balanced phone-type output jack that outputs the signal from the EFFECT bus. You use this jack, for example, to connect to an external effector. 8 RETURN L (MONO), R Jacks These are unbalanced phone-type line input jacks. The signal received by these jacks is sent to the Stereo bus and the AUX bus. These jacks are typically used to receive a return signal from an external effector (reverb, delay, etc.). NOTE These jacks can also be used as an auxiliary stereo input. If you connect to the L (MONO) jack only, the mixer will recognize the signal as monaural and will propagate the identical signal on both L and R jacks 9 REC OUT (L, R) Jacks By connecting these jacks to an external DAT recorder or cassette recorder, you can record the same signal that is being output from the ST OUT jacks NOTE The mixer's ST Master Fader has no affect on the signal output from these jacks. Be sure to make appropriate level adjustments at the recording device side.

Use these jacks when you want to connect a CD or DAT directly to the mixer for monitoring NOTE You can adjust the signal level using the 2TR IN control in the Master Control section. A FOOT SWITCH Jack This phone input jack can connect to the (separately sold) YAMAHA FC5 foot switch. With the foot switch connected, you can use your foot to toggle the digital effects ON and OFF. B POWER Switch Use this switch to set mixer power to ON or STANDBY. Note that trace current continues to flow while the switch is in the STANDBY position. If you do not plan to use the mixer again for a long while, be sure to unplug the adaptor from the wall outlet. C AC ADAPTOR IN Connector Connects to the included PA-20 power adaptor (see page 5). Use only the PA-20 adaptor included with this mixer. Use of a different adaptor may result in fire or electric shock.
