3. Output Level Meter
These 8-segment meters, located on each of the eight
output section, will allow you to see your channel's
output signal level between -0 and 0 dB. The red clip
LED lights up a few dB before overload occurs, therefore
users are advised to turn the output level control down
slightly to help keep the integrity of their audio.
4. In 1 / In 2 Buttons
These buttons will allow you to select the corresponding
output channel's signal between Main Input 1 (released)
and Main Input 2 (pushed-in).
5. Mono Button
This button will swap that particular channel's incoming
signal between a stereo (released) signal and a mono
(pushed-in) signal. When mono is selected, the left and
right channels of the signal will be combined into a mono
signal.
6. Headphone Outputs
This output, located on every headphone amp channel,
is used to connect to headphones to monitor that
particular channel's audio signal.
7. Output Level Control
This control adjusts the outgoing left and right signal
level from each channel, which is sent to the headphone
outputs.

9. Headphone Outputs
These outputs are used to connect
to headphones with a loading
of 100 ohms or greater. The
signal sent through these outputs
will be from the corresponding
headphone amp channels.
10. Direct Inputs
Connecting any device's output
to these 1/" TRS inputs will allow
you to feed in an external stereo
device to the corresponding output
channel. When a connection is made to the direct input,
it will have priority over the main input signal.
11. Main Inputs
These balanced 1/" inputs accept
signals from external devices,
the signal of which can be used
for monitoring using the PHA
headphone distribution amp.
Plugging a mono device into the
left input jack while leaving the
right jack free will allow the mono
signal to be doubled over to the
right input also.
12. AC Power Inlet
This inlet is used to connect the provided AC power
cable, the other end of which is connected to a suitable
power source. Check local voltage levels are compatible
before attempting to use this device. The power supply'
s fuse is imbedded in this socket. If for some reason the
