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. 3Effect 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 k.. 4Foot 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 Input/output panel Input/output panel put. 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. The nominal input level and impedance are –10 dB/ 600. for the AUX IN jack, and –10 dBV/600. for the TAPE IN jacks. 6External output jacks (REC OUT/MONITOR/ MAIN) These are output jacks which send line level signals from the EMX660 to external devices. A stereo recording device such as a cassette deck, DAT or MD recorder can be connected to the REC OUT jacks, and a playback device such a power amp can be connected to the MONITOR and MAIN jacks. The signals sent from each jack are as follows. • REC OUT jacks: The MAIN bus signal before it has passed through the MASTER control and graphic equalizer • MONITOR jack: The MONITOR bus signal which has passed through the Monitor MASTER control and graphic equalizer • MAIN jack: The MAIN bus signal which has passed through the Main MASTER control and graphic equalizer The nominal output level and impedance are –10 dBV/10 k. for the REC OUT jacks, and +4 dB/10 k. for the MONITOR/MAIN jacks. EMX660—Owner’s Manual 10 Front and rear panel 10 Front and rear panel l 1Speaker output jacks (POWER AMP 1 A/B, POWER AMP 2 A/B, BRIDGE) Speakers can be connected to these jacks. The EMX660 contains a two-channel power amp, and there are three ways in which the speakers can be connected to the EMX660. At this time, use the power amp select switch J on the control panel to select a signal sent to the correct jacks. When the power amp select switch is set to MAIN-MONITOR or MAIN-MAIN: • Two-channel connection Two 4–8. speakers can be connected to the A jack or B jack of the POWER AMP 1/2 (maximum output 300W+300W). • Two-channel parallel connection Two 8–16. speakers can be connected to the POWER AMP 1 A/B jacks and two more to the POWER AMP 2 A/B jacks, for a total of four speakers (maximum output 300 W+300 W). When the power amp select switch is set to MAIN-BRIDGE (Bridge connection) • One 8–16. speaker can be connected to the BRIDGE jack (maximum output 600 W). 2Power switch This switch turns the power of the EMX660 on/ off.

Caution: When using a bridge connection, do not connect anything to the POWER AMP 1 and POWER AMP 2 jacks. Likewise, when using the POWER AMP 1 and/or POWER AMP 2 jacks, do not connect anything to the BRIDGE jack. EMX660—Owner’s Manual Installation/Connection 11 EMX660—Owner’s Manual Installation/Connection Installation The EMX660 uses a forced cooling system with intake on the bottom of the rear panel and exhaust on the top of the rear panel to avoid blocking the heated air flow. Connection When connecting various devices, be sure to use cables and plugs of the appropriate standard. Speaker connection There are three ways in which speakers can be connected to the EMX660. 1Two-channel connection — A single speaker each can be connected to either the A or the B jack of POWER AMP 1 and of POWER AMP 2. 2Two-channel parallel connection — Two speakers can be connected in parallel to both the A and B jacks of POWER AMP 1 and of POWER AMP 2. 3Bridge connection — A single speaker can be connected to the BRIDGE jack. For each of these, the required speaker impedance will differ. Refer to the following diagram, and make sure that the speaker impedance is not less than the specified value.
