Using your Audibox
The EarDriver is a compact
Headphone Amplifier. It is a self-
contained, stand alone unit capable
of running one stereo signal to 4 out-
puts, or two stereo signals to 2 out-
puts. Each Output is a standard Tip
Ring Sleeve headphone jack with its
own Level control.
Inserting Left and Right Jacks into
Channels 1 and 2 will automatically
link them to inputs 3 and 4, unless
you insert other jacks into inputs 3
and 4.
There is also a Minijack Input for
Channels 1 and 2, and another for
Channels 3 and 4.
The EarDriver has many applications
for Live Sound, Studio or Broadcast
use.
Typical input types are:
• Any line level signal - mixing con-
soles, MP3 players, laptop compu-
ter sound cards, CD players, audio
from DVD players, cassette decks,
tape decks, VCR audio and more
Operating instructions
Input Connections
A stereo line
level source plugs into the Left and
Right Inputs for Channels 1 and 2.
Alternatively the Minijack input can
be used.

You can connect another 2 sets of
headphones into Outputs 3 and 4 to
run from the same Input signal as 1
and 2. If you want to use a different
signal, insert jacks carrying that signal
into the Left and Right Inputs (or the
Minijack Input) for 3 and 4.
Power Requirements
The EarDriver is an active device,
ie.
it needs power to run. This power
needs to be supplied by an External
12 - 15 V DC Power Supply
The EarDriver has a DC input con-
nector for connecting an external 12
- 15 V DC power supply. Any 12V DC
wall connector capable of supplying
200 mAmps will work, although for
greatest headroom we recommend
the Audibox PSU which can supply 15
V DC to multiple Audibox devices.
Note the wiring of the connector: the
outer sleeve is –, the inner is +.
