MAIN SECTION:
1 DIRECT IN
You can use this socket to feed and additional stereo signal into your HPA6. This
socket is in "priority". It means that when you insert the jack, the signal fed into
the MAIN input on the rear panel will be disconnected.
2 INPUT GAIN
This knob controls the level of the signal applied to the MAIN or DIRECT IN inputs.
3 INPUT LEVEL
This Led Meter informs you about the level of the input signal. The range goes
from
24 dBu to +18 dBu. For the best quality of input signal the operating
leds should be those from +6 to +18 dBu. The CLIP led should light up only
occasionally. If CLIP led is always on, you must reduce the input level through the
input gain control. If only -18 and -12 dBu leds are operating, you will experience
a bad S/N ratio and increase the input level.
CHANNEL SECTION
There are 6 identical channels on your HPA6 with identical functions and
performance.
4 AUX IN
This stereo input is useful when you want to feed an additional signal with the signals
applied to MAIN or DIRECT IN inputs. If you have a stereo signal depress the MONO
switch. If you have a mono signal, press the MONO switch if you want such signal
to appear on both ears.
5 L&R MUTE SWITCHES
Through these switches you can mute the respective input signals one at a time
or both at the same time.
