By using the PAD switches (control panel 5) you can connect any of the jacks to a wide range of sources from mics to line level devices (synthesizers or rhythm boxes etc.). The Lo-Z jacks can provide +48 V phantom power, allowing you to use condenser microphones. Both Hi-Z and Lo-Z are balanced, and are compatible with microphones of output impedance 50~600Ω or line level devices of 600Ω. The nominal input level is -40 dB~-10 dB for the Hi-Z jacks, and -50 dB~-20 dB for the Lo-Z jacks. Pin connections for the Hi-Z and Lo-Z jacks are as follows. Lo-Z jacks (XLR type) Hi-Z jacks (TRS phone jacks) Pin 1: ground Pin 2: hot (+) Pin 3: cold (-) Sleeve: ground Tip: hot (+) Ring: cold (-) S RT + - GND GND - + Note: It is not possible to simultaneously use both the Hi-Z and Lo-Z inputs of a given channel. For each channel, use only one of the inputs as appropriate for the input source. Phantom power is switched on/off in simultaneously for channels 1~6. For this reason, devices which do not require phantom power must be connected to the Hi-Z or LINE jacks if the PHANTOM +48 V switch (control panel L) is on. 2 Channel input jacks (MIC/LINE) 5~6 These are the input jacks for channels 5~6. Microphones can be connected to the MIC jacks, and stereo line level devices (such as synthesizers or rhythm boxes) can be connected to the LINE jacks. The MIC jacks are balanced, and are compatible with microphones of output impedance 50~600Ω. The LINE jacks are unbalanced, and are compatible with line level devices of 600Ω output impedance. Nominal input level is -50 dB for the MIC jacks and -20 dB for the LINE jacks. Note: It is possible to simultaneously use both the MIC and LINE inputs for a given channel. 3 Effect output jack (EFFECT OUT) The input of an external effect such as a delay or echo can be connected to this jack. The signal adjusted by the EFFECT control of each channel will be sent to the EFFECT bus, its level adjusted by the EFFECT OUT control, and output from this jack. The nominal output level and impedance are +4 dB/10 kΩ. 4 Foot switch jack (FOOT SW) A separately sold Yamaha FC5 foot switch can be connected to this jack. If a foot switch is connected to this jack, you can use your foot to switch the built-in digital effect on/off. The Digital Effect ON switch on the front panel must be set to ON in order to use a foot switch. 5 External input jacks (AUX IN/TAPE IN) These are input jacks that allow the signal from an external device to be added to the MAIN output. Monaural output devices such as external effects can be connected to the AUX IN jack, and stereo output devices such as cassette recorder or CD players can be connected to the TAPE IN jacks.
