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.
2.1 Front panel
This section describes how to use the front panel of the AMP800, illustrated as follows:
Fig. 2.1: AMP800 front panel
In the previous illustration, each control element is associated with a callout, for example . 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 and . To
manage the signal in each of these Input Channels, use these control elements:
LEVEL control: To adjust the input level of a signal, turn this control toward 0 (minimum level)
or, alternatively 6(maximum level).
2. CONTROL ELEMENTS

7
MINIAMP AMP800
DEUTSCH
2. CONTROL ELEMENTS
BALANCE control: To adjust the stereo image of a signal, turn this control toward L (left) or,
alternatively R(right).
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 through
. To manage each Headphone Channel, use these control elements:
(headphone) connector:To connect a headphone, use this stereo, ¼" TRS connector. For
details about TRS plugs, see 4. AUDIO CONNECTIONS.
INPUT button: To select an Input Channel, push this button. When you listen to:
VInput Channel A, this button is not pushed in and not lit
VInput Channel B, this button is pushed in and lit
PHONES LEVEL control: To adjust the level of a headphone signal, turn this control toward 0
(minimum volume) or, alternatively 6 (maximum volume).
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).
(power)button:To turn theAMP800 onand off,push this button.When youturn the AMP800:
Von, this button is pushed in and lit
Voff, 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.
2.2 Rear panel
This section describes how to use the rear panel to set up the AMP800.
The following illustrates the rear panel of the AMP800:
Fig. 2.2: AMP800 rear panel
In the previous illustration, each control element is associated with a callout, for example . In
this section, use these callouts to identify details about each control element:
POWER connector: To power the AMP800, connect the power supply unit to this connector.
This power supply unit is delivered with the AMP800.
PHONES OUT connectors: For each Headphone Channel (1, 2, 3, and 4), the rear panel
includes an additional headphone connector, which is a stereo, ¼" TRS connector.

MINIAMP AMP800
3.SETUPEXAMPLE
LINK OUT A connectors: If you need more than the 4 Headphone Channels that a single
AMP800 provides, connect these balanced, ¼" TRS connectors (Left and Right) to the inputs
of another AMP800. The LINK OUT A connectors send only the signal of Input Channel A,
without any LEVEL or BALANCE settings.
INPUT connectors: For each Input Channel (A and B), the rear panel includes 2 balanced,
¼" TRS connectors (Left and Right). Connect them to the outputs of a mixer, a CD player, or
a soundcard. For mono signals, use only the Lconnector.
If the output is balanced and you insert unbalanced, ¼" TS plugs in the INPUT connectors,
the signal level will decrease 6 dB. To raise the signal level, use the relevant LEVEL
control ( ).
SERIAL NUMBER: To register the AMP800, use this unique serial number.
For details about TS and TRS plugs, see 4. AUDIO CONNECTIONS.
