AudioSource Preamp 5.1 Owner's Manual

Basic Guidelines

The preamplifier is the control unit of your audio system. The Preamp 5.1 is a dual channel preamplifier. In the
modular chassis, the Preamp 5.1 links the modular amplifiers and/or equalizers to your source component, such
as a CD or DVD player.

Using The Controls

Power

1
Press this switch to turn the unit on or off. The red LED in the switch will light to show power is on.
2

Level

Turn this knob clockwise to increase the overall system volume. Be careful not to set the level so high as to
cause distortion, which could damage the speakers.
Bass & Treble
3
Turn these knobs clockwise to increase the amount of bass (low frequencies) or treble (high frequencies).
The 12:00 position indicates a flat response, equal levels of bass, treble and midrange.

Balance

4
Turn this knob clockwise or counterclockwise to change the proportion of the signal output to either channel.
The 12:00 position indicates equal output to each channel.

Line

5
This button refers to the inputs on the back of the Preamp 5.1. If you are using XLR or balanced inputs (line 2),
depress this button. If you are using RCA or unbalanced inputs (line 1), leave this button in the out position.

Tone

6
This button corresponds to the bass and treble knobs. To engage the bass and treble knobs, depress this button. To bypass the bass and treble knobs, so
that they do not affect your sound, leave this button in the out position.

Hooking It Up

DVD Player,
CD Player or
Other Source
When connecting the Preamp
5.1, turn off or unplug your
components. This prevents
loud "pops" that might
damage your speakers
while you connect the cables.
The diagram at right shows
the Preamp 5.1 in conjunction
with other components from
AudioSource' s modular separates
line. The equalizer is optional, and
you can substitute any amplifier
or equalizer; the setup is the same.
Also, XLR/balanced connections
follow the same paths as the
RCA/unbalanced connections
described below.
1. Connect the source component
(e.g. DVD player, CD player, cassette deck, microphone) to the Preamp 5.1 input.
2. If you are using a graphic equalizer, connect the two output channels of the Preamp 5.1 to the equalizer inputs. In this diagram, Channel 1 is left and
Channel 2 is right. Connect the Channel 1 and 2 outputs from the equalizer to the amplifier inputs. Please note that the Amp 5.1 is a single-channel
monoblock amplifier, so two are shown here. Rather than two monoblocks, you could use a single stereo amplifier, such as an Amp 6.2 or 6.3.
3. If you are not using a graphic equalizer, connect the two output channels of the Preamp 5.1 to the amplifier inputs.
