10. SPEAKER OUTPUT TERMINAL
These terminals connect up to five speakers in 4
Ω, 8Ω or High Impedance mode.
NOTE:
Only speakers connected to the High-Impedance terminals are controlled by the front-panel Speaker
Selector switches.
11. LINK OUT
This line-level output connects the unit with an external mixdown deck or other recording source.
12. PREAMP OUTPUT
This output connects the unit with an external power amplifier. Inserting a plug into the Preamp Out jack will
disconnect signal to the unit’s power amp, sending the output of the internal mixer to the external amplifier.
13. LINK IN
This line-level input connects the unit with an external mixer for expanded input channels.
14. AMP IN
This input connects an external mixer or preamp with the unit’s power amp. Inserting a plug into the Amp In
jack will disconnect all input signal from the unit’s internal mixer. Only signal from the external source will be heard.
15. GND TERMINAL
This grounding terminal is provided for connecting with the chassis of a turntable or other input device to
reduce hum and other ground loop noise. It may also be connected to a true earth ground, such as an AC
third-pin ground or water pipe, to further reduce ground loop noise.
16. CH6/PHONO SELECTOR SWITCH
This switch is used to select the input level for Channel 6. When set to Mic/Aux position, CH6 input is set to
Mic/Aux level. When set to PHONO, CH6 input is at Phono level (The product is set to Mic/Aux position,
when is assembled).
NOTE:
When the CH6 Input selector is set to PHONO, the input gain of CH6 is unaffected by that channel’s
Input Gain Control.
USA/CANADA & Associated Version is used CH6/CD SELECTOR SWITCH
17. INPUT GAIN CONTROLS
These knobs provide continuous control of the input levels for each of the six input channels. When adjusting
the input gain, make certain that the levels are not set too high, or distortion will result.
