SAFETY INSTRUCTIONS

CAUTION:

WARNING:

To reduce the risk of electrical shock, do not remove
the cover (or back). No user serviceable parts inside;
refer servicing to qualified personnel.

To reduce the risk of fire or electrical shock, do not
expose this appliance to rain or moisture.

This symbol, wherever it appears, alerts
you to the presence of uninsulated
dangerous voltage inside the enclosure

- voltage that may be sufficient to con­stitute a risk of shock.

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

This symbol, wherever it appears, alerts
you to important operating and mainte­nance instructions in the accompanying
literature. Read the manual.

A. INPUT CHANNEL SECTION

1. BALANCE INPUT (MIC)

Electronially Balanced inputs acceptable a standard XLR male connector.
+ 48V Phantom Power available on each input Mic socket.
and this switch is on Rear Phantom Power.

2. LINE INPUT

The unbalanced Mic input is provided for the use of an unbalance mic and is
designed to accept an unbalanced high impedance input signal.
(This use for connection Deck, Turntable, Keyboard etc..)

3. TRIM

This has a function which adjusts the input sensitivity of each channel in order
to input the constant level of the signal.

4. HI EQ

This control gives you up to 15 dB of boost or cut at 12KHz and above, and it is
also flat at the detent. Use it to add sizzle to cymbals, and an overall sense of
transparency or edge to key-boards, vocals, guitar, and bacon frying. Turn it
down a little to reduce sibilance, or to hide tape hiss.

5. LOW EQ

This control gives you up to 15 dB boost or cut at 80Hz and below. This circuit
is flat (no boost or cut) at the center detent position.
This frequency reptesents the punch in bass drums, bass guitar, fat synth
patches, and some really serious male singers.

6. SEND /EFF

This is normally derived after the EQ and channel fader (POST FADE, POST
EQ), and is therefore follow any changers in fader level. They are normally
used to drive effects processing units which are fed back into the mixer and
which must fade out with the input channel.

7. PAN

The pan control sends continuously variable amounts of the post fader signal to
either the left and right main busses. In the center position equal amounts of
signal are sent to the left and right.

8. CHANNEL FADER

This is function to adjust the volume of signal connection into each channel and
adjust the volume of output, together with master fader. Normal operating
position is at the “O” mark, providing 4dB of gain adove that point, if required.

9. PEAK

A red LED indicates a signal level at the insert return point, premaster fader, It
illuminates at approximately 5dB below clipping.

11. EFFECT RETURN

This is used for adjusting frequency of
echo repeat, since too echo repeat may
cause a nowl, please adjust frequency
properly.

12. AUX RETURN

This is used for adjusting frequency of
echo repeat, since too echo repeat may
cause a nowl, please adjust frequency
properly.

13. EFFECT PROGRAMS

When adjust switch 19,20,21,22 ,ore
effects are displayed.

14. UP TAPE SWITCH

One push, one program up, push with
more than 5 swconds.

15. DOWN TAPE SWITCH

One push, one program down, push with
more than 5 swconds, hi-speed program
down.

16. EFFECT LEVEL

Using by this control, you can adjust
