1. INTRODUCTION
The Headphone Distribution Amplifier 0700-001 features three audio inputs, a pilot mic input, and
eight controllable audio outputs. The pilot mic input will override the other inputs when active. The
unit is designed to integrate into any entertainment system with analog audio capability and
controllers that allow you to select different audio sources in the aircraft.
This guide describes general configuration information for the Rosen Headphone Distribution
Amplifier with any audio source equipment to supplement the Outline and Installation Drawing (P/N
0700-001-CD).
Note: Only trained and qualified personnel should perform installation and service.

2. DEFINITIONS
Independent
channels
All eight outputs, or channels, operate independently.
Source select
A switch that enables you to select between three different audio input
sources independently.
Output channel
An audio output from the Headphone Distribution Amplifier (outputs 1-8).
Input channel
Refers to the line-level audio source (inputs channels A, B, and C. For
example, a DVD player, iPod, and RosenView VX.

2.1. Operating Modes
Each output channel may be configured to one of two modes of operation by setting the DIP
switches according to the ON indicators on the audio distribution amplifier.
Fixed output
Keeps the output channel set to a specific input channel: either A, B, or C.
Switched output
Allows the user to select input channels independently of the other output
channels. Requires a source select switch wired to the unit.
3. CONFIGURATION DIP SWITCHES
Use the configuration DIP switches to set the audio control for all seats. Each output channel uses
two switches. Figure 1 shows the pairs of switches that control each channel.
Figure 1 The factory default DIP switch settings are OFF (up)
3.1. Auxiliary Configuration Switches
The Headphone Distribution Amplifier features an optional 5V power supply that will handle up
to 0.5 A.
The Channel C Control is an optional switch that enables the third audio input. Leave these
and any other unused switches OFF (up) unless you need to configure them.

4. CONFIGURING A SINGLE OUTPUT CHANNEL
Configuring a single output channel depends on several variables.
Number of audio inputs
Use of a source select switch (such as a controller, IR remote, or at the seat)
Choice of fixed inputs: channel A, B, or C
4.1. Fixed Mode Example
If you are using only one input, you do not need a source select switch or need to enable
channel C.
If you do not need a source select switch for the output channel, see Table 1. This example
shows that using DIP switches 1 and 2 (SW1 and SW2) will set the output to receive a desired
input: either A, B, or C for seat 1.

*Channel C control, SW6 (small bank), does not have to be ON to listen to Channel C in fixed
mode.
Note: Do not set all DIP switches to ON. Doing so will cause the PA to override the audio all
the time.
4.2. Switched Mode Examples
If you use a source select switch, see Table 2. This example shows that channels A and B for
seat 1 are enabled using a source select switch. The Channel C enable switch (SW6) is OFF.

For independent switching, configure desired seats to input Channel A.
The audio is constantly on pilot
mic with this configuration
The DIP switch settings are
identical to the fixed mode
Channel A in Table 1; the
difference is that a source select
switch is used to toggle between
inputs A and B.

To configure the remaining output channels (2-8), copy the appropriate switch settings from
Tables 1-3. Fixed modes will use either an ON/OFF, OFF/ON, or OFF/OFF combination and
switched modes will always use the OFF/OFF combination.
If you use three audio sources and a source select switch, configure the DIP switches as
shown in Table 3. The Channel C Enable switch must be ON to use the third audio input.

4.3. Installation Example
You can mix the audio control and configure each seat differently, as shown in Figure 3.
Channels 5 and 6 are set to Input A, and these seats have a choice. Either they may have a
source select switch to allow them to change their channel, or they can remain without a
source select switch and stay on input A.

The N/A outputs do
not switch the audio
properly
Channels 1, 2, and 7are set to Input C.
Channels 3, 4, and 8are set to Input B.
The seats for these six channels do not
have source select switches.
Only channels 5 and 6, which are set to
Input A, can use a source select switch.
This is because the DIP switches
controlling these channels are turned
OFF.

5. MOUNTING
Mount the Headphone Distribution Amplifier in any orientation using the four mounting slots in the
flange brackets on the exterior housing. Refer to Note 3 on the Outline and Installation Drawing
0700-001-CD.
6. ADJUSTING THE MAXIMUM AUDIO LEVEL
The factory defaults for the potentiometers, as shown in Figure 4, are set to line level. This means
that the signal coming out of the amplifier is equal to the signal going in. Adjust each knob
individually to set the maximum audio level for each input.
After establishing the maximum audio level, use the potentiometers to match the line levels for the
audio sources to provide a consistent volume when switching input sources. To lower the audio
level, turn the knob counter-clockwise; to raise it, turn the knob clockwise.

Note: To avoid popping when you power the system on and off, do not reverse or interconnect the
ground and return lines.
