Fig. 2.1: AMP800 front panel
In the previous illustration, each control element is associated with a 
callout, for example  
(1)
. In this section, use these callouts to identify 
details about each control element. For each Input Channel (A and B), 
the front panel includes control elements  
(1)
  and  
(2)
. To manage the 
signal in each of these Input Channels, use these control elements:
(1) 
LEVEL control: To adjust the input level of a signal, 
turn this control toward 0 (minimum level) or, 
alternatively 6 (maximum level).
(2) 
BALANCE control: To adjust the stereo image of a signal, 
turn this control toward L (left) or, alternatively R (right).
(3) 
A + B meter: To monitor the combined level of both signals 
(A and B), use this meter. An LED glows next to the value that 
identifies the combined level (-24 dB to 0 dB). If the signal is too 
strong, the CLIP LED glows. Most of the time, the optimal level 
is 0 dB (a full signal).
For each Headphone Channel (1, 2, 3, and 4), the front panel includes 
control elements  
(4)
  through  
(7)
. To manage each Headphone 
Channel, use these control elements:
(4) 
 (headphone) connector: To connect a headphone, 
use this stereo, ¼" TRS connector. For details about TRS plugs, 
see 4. Audio Connections.
(5) 
INPUT button: To select an Input Channel, push this button. 
When you listen to:
Input Channel A, this button is not pushed in and not lit
Input Channel B, this button is pushed in and lit
(6) 
PHONES LEVEL control: To adjust the level of a headphone 
signal, turn this control toward 0 (minimum volume) or, 
alternatively 6 (maximum volume).
(7) 
CH meter: To monitor the level of a headphone signal, use this 
meter. An LED glows next to the value that identifies the 
headphone volume (-24 dB to 0 dB). If the signal is too strong, 
the CLIP LED glows. Most of the time, the optimal volume is 
0 dB (a full signal).
(8) 
 (power) button: To turn the AMP800 on and off, push this 
button. When you turn the AMP800:
on, this button is pushed in and lit
off, this button is not pushed in and not lit
◊ 
When you finish using the AMP800, unplug the power supply 
unit from the power source. As long as the power supply 
unit is connected to a power source, the power supply unit 
consumes energy.
2.  Control Elements
The AMP800 is a headphone amplifier that includes 4 Headphone 
Channels, so you can share the
AMP800 with other musicians. In addition, each musician can choose 
between 2 audio channels: Input Channel A and Input Channel B.
◊ 
Ensure that only qualified personnel set up and operate 
the AMP800.
