Operating Manual for AS-QUAD Series
**Please visit for the latest updates**www.galaxyaudio.com
Introduction
1
Thank you for purchasing the Galaxy Audio AS-QUAD
System. This manual covers the complete functions and
operation of the QUAD as well as the optional transmitters.
Please read this manual carefully to use the Quad to its
fullest potential. The Quad is a single space rack mount
receiver chassis, which may be loaded with up to 4 UHF
diversity wireless mic receivers. Each of the receivers
features an LCD display, 96 selectable channels, RF/AF
indicators, and volume control. The chassis has an
individual balanced XLR output for each receiver, and a
mix output (balanced XLR and unbalanced ¼” jacks) with a
Hi/Low level switch. The mix output provides a mixed
signal from all of the receivers, based on the individual
volume control settings. This mix output is very useful
when main mixer input channels are in short supply. The
internal antenna distribution system allows the 2
detachable antennas to serve all of the receivers. In
addition, the Quad chassis provides power to all 4
receivers while occupying only 1 AC outlet.
There are multiple transmitter options for the Quad
receivers. Choose between Dynamic or Condenser
Handheld Microphones or a Body Pack transmitter (with
multiple Headset & Lav options). Each transmitter features
an LCD display showing channel number, frequency, and
battery level. All transmitters feature a mute switch and run
off of 2AA batteries (can be rechargeable).

Operation
A. Power Supply and Main Power Switch
1. Starting with all power switches off, plug the included
DC Power Supply into the DC Input Jack (17) on the rear
panel. Plug the other end into an AC wall outlet. Switch on
the Main Power (8).
B. Output Jacks
The QUAD offers two different methods of connecting the
Mic Receiver Outputs to the Inputs of devices such as
mixers, amplifiers, or recording gear.
1. You may connect each Receiver Module Output (A
through D, 13-16) to separate input channels on a
mixer. This method is useful when independent signal
processing or routing of the Mic Receivers is required.
Note: The Module Ch. A Output jack (16) corresponds
to the module closest to the Main Power Switch (8) on
the front panel, and so on down the line.
2. Or, you may simply use one (or both) of the Mix
Outputs (10 or 12), which will supply a mix of all the
Receiver Modules based on the Volume settings of
each Module (7). Use the Hi / Lo Switch (11) to
choose the overall Output Level (Mic or Line Level).
This method is useful to conserve mixer input
channels, or when a simple setup is desired that does
not require independent signal processing or routing
of the Mic Receivers.
C. Wireless Mic Receiver Modules
This system may be configured with up to four wireless mic
receiver modules with selectable PLL 96 channel
operation. 3
1. Turn the power switch (7) clockwise to turn on the
receiver.
2. The LCD display (1) will show “On” and the channel that
was last in use when the unit was turned off.
3. To select a different channel, press the set button (5).
The channel number will flash in the in LCD display. Press
the up or down button (6) to select a channel to use, and
then press the set button. After a channel has been set,
press either the up or down button to display the frequency
of the selected channel.
4. Adjust the volume controls to the desired level. It is
important to set the gain structure properly to ensure the
best signal to noise ratio. Typically, you will want to set the
Output Volume controls of the Mic Receiver Modules as
high as possible without causing distortion to the Input of
the next device, and so on down the line.
5. When receiving signal, the A/B diversity indicator (2) will
light RED or Green to show the normal condition. The RF
indicator (3) will light to show RF received and the AF
indicator (4) will show audio received.
6. When multiple Transmitters (Mics) are used, each must
be set to a different channel to avoid interference. Set the
Mic Receiver to the same channel number that is set on
the Transmitter that you wish to receive.
Notice: Changes or modifications not expressly approved
by the party responsible for compliance could void the
user's authority to operate the equipment.
