There are no user serviceable parts inside the unit. Do not open the
unit. Do not attempt to service the unit yourself. Refer all servicing to
qualified personnel. Opening the chassis for any reason will void the
manufacturer's warranty. Do not get the unit wet. If liquid is spilled on
the unit, shut it off immediately and take it to a dealer for service.
Disconnect the equipment during storms to prevent damage.

A. INPUT CHANNEL SECTION
1. BALANCED INPUT (MIC)
Mic balanced inputs accept a standard XLR male connector.
+48V Phantom Power is available on XLR inputs.
2. LINE INPUT
The 1/4”TRS jack socket is designed to accept a high impedance input
signal.(eg. CD player, Guitar preamp, Keyboard etc.)
3. INSERT JACK
Channel insert to send the channel signal through outboard audio processors such as
limiters, EQ etc. This will require a splitter cable that has a TRS 6.3mm jack to connect
to the Insert and 2 x mono unbalanced connectors to connect send and return to the
processor
4. PEAK LEVEL INDICATOR
Gives a visual indication of when the signal is within 10dB of clipping

5. PAD (-20dB)
Attenuates the signal by 20dB when pushed in
6. GAIN
Adjusts the input sensitivity. Too high a value can cause distortion, too low a value can
increase background noise
7. HIGH
Provides ±l5dB of fixed frequency equalization that shelves at 10kHz
8. MID
Provides ±l5dB of fixed frequency equalization that centres at 2kHz
9. LOW
Provides ±l5dB of fixed frequency equalization that shelves at 120Hz
10. MONITOR
Adjusts the level of the signal sent to the monitor section and output
11. EFFECT
Adjusts the level of the signal routed to the internal digital delay (or external effects if the
effect send and return are connected)
12. PAN
The PAN control varies the balance of the left and right feed of the signal to the master
output. This has the effect of positioning the signal at a particular point within the stereo field
13. MUTE
Mutes the channel signal feed to the main mix
14. PFL
Pre-Fader Listen switch. Feeds the signal through to the headphones and level meters for
monitoring and isolated signal adjustment
15. CHANNEL FADER
Adjusts the level of channel signal routed to the main mix. Normal full volume is 0dB although
up to +4dB gain above this is available
B. MASTER SECTION
16. EFFECT SEND
Adjusts the overall level of the combined effect sends from each channel to help avoid
overloading the effects unit
17. TONE
Adjusts the high frequency component of the internal delay by ±10dB shelving @12kHz
18. EFFECT LEVEL
Adjusts the level of the effects unit routed to the main mix
19. EFFECT PAN
Adjusts the L + R balance of the internal or external effects fed to the main mix
