Grey II 8
Analog mixer - 8 Mic/line inputs + 1 stereo channel
Grey II 8 is the second generation of Grey mixers,
that features 8 Mic/line inputs with balanced XLR/
TRS connectors, 1 stereo input, 4-band equalization per channel and a mp3 player with USB port.
The mixer also sports 1 auxiliary input/output, 16
types of adjustable delays, phantom power for all
its inputs and a general 7-band stereo equalization.
Grey II 8 stands out due to the quality of its low
noise preampliers that deliver exceptional sound
clarity with strong anti-interference ability, the
quality of its sliding faders and its solid construc-
tion, providing a quality alternative for small scale
applications.

2. INPUT CHANNEL SECTION
1. Balance Input
Electronically Balanced inputs acceptable a stand-
ard 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 a unbalanced mic and is designed to accept a
unbalanced high impedance input signal (This use
for connection Deck, Turntable, Keyboard ect.).
3. Gain Control
Adjusts input sensitivity from -60dB to -20dB with
the -20dB pad switch in the out position, and -40dB
to 0dB when the -20 dB pad switch is pushed.
4. Low Cut
The LOW CUT switch, 75Hz at a rate of 18dB per
octave.
5/6/7.4-Band Fixed - Frequency EQ
The stereo channels (9-16) have a 4-bandxed frequency equalization: LOW shelving at 80Hz, LOW
MlD peaking at 400Hz, HIMID peaking at 2.5kl-lz,
and Hl shelvingat 12kHz.Each of these lters provides up to 15dB of boost or cut. As with the mono
channels the circuit is at (no boost or cut)at the
center detent positions.
8. Aux Send
Use this control to set the level of signal from external stereo source and the main signal control is
recontrolled by STEREO or MONO section.
9. EFF
Use this control when you want to get eect sound
by adjustment of input signal. When you dont use
external source, digital delay will be working which
installed inside.

10. Pan
The pan control sends comtinuosly variable
amounts of the post fader signal to either the le
or right main busses. In the center position equal
amounts of signal are sent to the le and right
busses.
11. Mute
All output from the channel are enabled when the
MUTE switch released and muted when the switch
is down.
12. Channel Fader
This is function to adjust the volume of signal connection in to each channel and adjust the volume of
output, together with master fader. Normal oper-
ation is at the O mark, providing 4dB of gain above
that point, if required.
13. OL (peak level indicator)
A red LED indicates a signal level at the insert return
point, pre master fader, It illuminates at approximately 5dB below clipping.
14. Solo
This lovable switch allows you to hear signals
through your head phones or control room without
having to route them to the main mix. You dont
even have to have the channels fader turned up.
Folks use solo in live work to preview channels
before they are letin to the mix, or to just check out
what a particular channel is up to any time during a
session. You can solo as many channels at a time as
you like.

3. MASTER SECTION
15. Stereo Graphic Equalizer
2X7-band equalizer is provided for tone control over
each frequency, and for precise high quality sound
by nal tone control.
16. Phantom Power Switch/LED
Depressing this switch applies 48VDC across all
microphone input channels connectors for remote
powering of condenser microphones. The LED will
be runed on when phantom power start working.
17. Outputs Level Indicator
Condition on the way of operation. Therefore, you
can see output condition thru this master level
indication.
18. Power LED
The POWER LED will be turned on when start
working.
19. FX Level
Using by this control, you can adjust signal level of
echo repeat & exterior eect.
20. Output Main Fader
This is a master fader for adjustment for volume of
le/right output. Unity gain is the top their travel.
21. 9/10 VOLUME
Using by this control, you can adjust signal level of
9/10(mp3).
22. HI(high)
You can adjust of 9/10 channel. See the "6.HIGH".
23. Low
You can adjust of 9/10 channel. See the "8.LOW".

This is used of adjusting volume of echo AUX sound.
When return AUX singal to used jack.
25. Aux send
When this button is up, Post signal work as send
signal. When this button is down, post signal work
as eect singal.
26. FX Send
This is used for adjusting volume of echo fx sound,
when sending echo sound to send jack in eect
panel.
27. Phone
This is a single volume control sends the level to the
headphones and main monitors.

(SEE NO.20) will be turned on when working.
36. Power Jack
This is out of connect the power suplly jack.
Repaining a sound mixing console requires special-
ist, but basic fault nding is whitin the scope of any
user if a few badic rules followed.
• Get to know the block Diagram of your console.
• Get to know what each component in the system is supposed to do.
• Learn where to look for common trouble spots.
The Block diagram is a representative sketch o fall
the components of the console; showing how they
connect together and how the signal ows through
the system. Once you have become familiar with
the various component have gained a valuable
understand of the internal structure of the console
and tracking down the problem by elimination.
• Swap input connections to check that the
source is really present. Check both Mic and
Line inputs.
• Eliminate sections of the channel by using
the insert point to re-route the signal to other
inputs that are konbs to be working.
• Route channels to dierent outputs or to aux
sends to identify problems on the master section.
• Compare a suspect channel with an adjacent
channel which had been set up identically. Use
PFL to monitor the signal in each section.
