If a plug is inserted into only the L/MONO jack, the same signal will be sent to both L and R buses. The AUX1 knobs control the level at which signals from effect units etc. connected to the L/MONO, R jacks of AUX RETURN 1, 2 are sent to the AUX SEND 1 (2) fader. After being adjusted at the fader, the signal is output from the rear panel AUX SEND 1 (2). This knob is a low frequency equalizer that provides 80Hz shelving equalization of the signal input at AUX RETURN. • The signals input to each input channel and processed This knob is a high frequency equalizer that provides through the 3-band EQ and the INPUT CH INSERT I/ 12kHz shelving equalization of the signal input at AUX O jack (Turn on a channel PFL switch.)

C METER SELECT switch and meter section The meters are dual-function LED meters that indicate signal levels as selected by the METER SELECT switch. • STEREO L,R ...... displays the output levels of the STEREO OUT jacks. 9 REC OUT control This knob adjusts the output level of the REC OUT jacks (connector 5) connected to a tape deck, etc. 0 TAPE IN control This knob adjusts the monitor volume of a tape deck etc. connected to the TAPE IN jacks. A PHONES control This knob adjusts the volume of a set of headphones connected to the headphone jack (PHONES). B PHONES jack Connect the headpones here. You can monitor the following signals: — Signals available for monitoring — • The main signal output to the ST OUT jacks (Turn off all PFL and AFL switches.) • MONO OUT level ...... displays the output level of the MONO OUT jack. • PFL/AFL level ...... displays the input level of the channel whose PFL switch is on, or the output level of the ST, MONO OUT, or AUX SEND jack whose AFL switch (master control section 4, 6) is on. • AUX SEND 1–4 ...... displays the level of the AUX signals output to the AUX SEND 1–4 jacks. D PHANTOM indicator This indicator will be lit when the PHANTOM switch (rear panel 2) is on. E PFL indicator This indicator will be lit when any of the channel PFL switches (channel control section 0) is on. At this time, the PFL/AFL meter in the meter section will indicate the level of the channel whose PFL switch is on.

(1: sleeve, 2: hot, 3: cold) Microphones of 50–600. or 600. line level devices can be connected here. When the PHANTOM switch (rear panel 2) is turned on, DC+48V will be supplied to pins 2 and 3 of these connectors. 2 INPUT B These are balanced phone connectors. (T: hot, R: cold, S: sleeve) Microphones of 50–600. or 600. line level devices can be connected here. Unbalanced phone plugs can also be connected, however, noise may occur with long cables, or cables subjected to strong electromagnetic fields caused by radio and TV broadcasts. 3 INPUT CH INSERT I/O 0dB These are input/output jacks located between the head amp and the equalizer of the input channel section. The nominal input level and impedance is 0dB/600., and the nominal output level and impedance is 0dB/10k.. These jacks allow you to insert your own graphic equalizers, compressors, noise filters, or other devices. INSERT OUT INSERT IN 4 TAPE IN Your DAT or cassette deck can be directly connected here for convenient monitoring.

In this case, the final output level is adjusted by the REC OUT control (master control section 9), and the STEREO L,R fader settings will have no affect. 6 STEREO OUT (L, R) This is the stereo output of the combined audio signals. Connect these jacks to the power amp that drives your main speakers. Alternatively, you...
