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 +15 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) Pin 1: ground Pin 2: hot (+) Pin 3: cold (-) Hi-Z jacks (TRS phone jacks) 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 the Lo-Z jacks of channels 1-4 and the MIC jacks of channels 5-6. For this reason, any devices other than condenser microphones must be connected to the Hi-Z or LINE jacks if the PHANTOM switch (control panel L) is on. 2 MIC, LINE, INST input jacks 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 1 & 2 jacks are unbalanced, and are compatible with line level devices of 600Ω output impedance. These two input jacks can be used simultaneously. Nominal input level is -50 dB for the MIC jacks and -10 dB for the LINE jacks. INST 1 & 2 jacks are unbalanced, can be used simultaneously, and their high input impedance makes them ideal for use with instruments such as electric-acoustic guitar and electric bass. They can also be used with line-level sources, such as synthesizers and drum machines. Nominal input level is -30 dB. Note: It is possible to simultaneously use both the MIC and LINE inputs for channel 5, and the MIC and INST inputs for channel 6. 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, 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. EMX660-Owner's Manual
