PRODUCT DESCRIPTION
The Concourse Q6A and Q8A are Active two-way high
performance speaker systems designed for sound reinforcement,
audio-visual and music delivery applications. They combine
quality transducers with high efficiency dedicated power amplifiers
to deliver the highest possible performance in lightweight and
durable ABS enclosures. Each model comes complete with
mounting brackets and hardware, facilitating easy installation.
Concourse Q6A
The Concourse Q6A is an active, two-way speaker system
consisting of a 6.5" low-frequency driver and a 1" dome tweeter
combined with a 50 watt, high-efficiency power amplifier. Be
aware of the position of the voltage selection switch before
connecting the power cord and be sure that the correct voltage
is selected before powering up the unit. Each unit is supplied with
a wall mounting bracket. There are two versions available:
• Concourse Q6AW – White color
• Concourse Q6AG – Gray color
Concourse Q8A
The Concourse Q6A is an active two-way speaker system consist-
ing of an 8" low frequency driver and a 1" dome tweeter com-
bined with a 50 watt high-efficiency power amplifier. Each unit
is supplied with a wall mounting bracket. There are two versions
available:
• Concourse Q8AW – White color
• Concourse Q8AG – Gray color
NOTE: Power cords supplied with Q6A and Q8A models vary
by country of sale. Be aware of the position of the voltage selec-
tion switch before connecting the power cord and be sure that the
correct voltage is selected before powering up this unit. Please
check with your QUAD Industrial sales office or local distributor to
ensure you have the correct version.
PRODUCT FEATURES (Q8A shown)
The Q6A and Q8A are fitted with a removable metal grille
finished with an opaque cloth backing. Two LEDs in the lower
right front of the cabinet indicate power status (Green) and
Amplifier Clip (Yellow).

Q6A and Q8A models include a switchable voltage power sup-
ply that accepts either 110-120VAC or 220-240VAC line power.
Selection is made through the two-position Voltage Select Switch
on the rear panel. In addition there is an IEC AC Input socket and
two position rocker Power Switch.
Both models are fitted with a 50 watt high efficiency power
amplifier with external heatsink. Ensure that the heatsink is not
obstructed and that adequate airflow can circulate around it to
ensure safe and reliable operation.
The amplifier accepts either balanced or unbalanced signals,
through a detachable Phoenix-style connector or a single RCA
connector. Nominal sensitivity of the Balanced input is +4dBu
and -10dBu for the unbalanced input. A rotary Gain Control is
provided to attenuate the volume.
Both models are fitted with 4 threaded inserts on the rear for
attaching the supplied mounting bracket. Access to the mounting
points is gained by removing the four screws and the blank cover
plate. There is also a threaded insert for attachment of a seismic
restraint tether.

INSTALLATION
Step 1 – Install bracket A to wall using suitable fasteners.
Step 1a – Remove four screws holding cover plate (2) on rear
of speaker.
Step 1b – Mount the bracket with the threaded bolt to the
cabinet using the four screws removed in step 1 (4).
Step 2 – Place the rubber friction washer over the bolt.
Step 3 – When the speaker is ready for installation, insert the
bolt in the wall plate bracket from below.
Step 4 – Place the dome cover over the bolt.
Step 5 – Place the lock washer and hex nut on the bolt. Tighten
gently, aim the speaker as needed and tighten firmly.
Step 6 – Ensure that seismic restraint cable is firmly attached
to both the loudspeaker and an anchor point on the mounting
surface.

CONNECTIONS & OPERATION
CAUTION: Before connecting this unit to the AC power supply
please ensure that the Voltage Selector Switch is set correctly for
the voltage in your region and that you are using a suitable
power cable.
The Q6A and Q8A may be connected to either a balanced audio
system or an unbalanced source. Typically, balanced connections
are preferred. Balanced connections are less likely to respond to
radio frequency interference or cross-talk from other sources, and
allow for longer cable runs. Unbalanced connections are accept-
able only where the mixer does not offer balanced outputs and
where the cable runs are less than 5m/15’.
Determine where the speakers will be placed and ensure that there
is AC power available nearby. In instances where there is no local
power outlet you may need to provide an extension cable. Ensure
that all local and national electrical codes are observed and that
the power cable used is properly rated. If in doubt consult with a
certified electrician or electrical engineer.
BALANCED CONNECTIONS
Balanced connections require a quality, two-conductor shielded
cable. Balanced connections require one conductor for the positive
(+) signal and one conductor for the negative (-) signal, a third
conductor (shield) to create a direct connection to ground (Earth).
Remove the detachable connector plug supplied with the speaker.
Prepare the cable by stripping each conductors’ insulation 6mm
(¼"). Insert each conductor into the appropriate position, noting
polarity and tighten the corresponding screw firmly. Once all wires
have been terminated inspect the connector plug to ensure that
there are no stray wire strands that could cause a short-circuit.
Balanced lines may be extended in parallel between speakers,
allowing several speakers to be driven from one mixer output.
However this configuration will present the signal source with a
lower impedance than it would typically drive and may cause
added distortion or even damage to the source outputs. The
recommended method for connection of multiple Q6A and Q8A
active loudspeakers to one source output is through use of a
suitable active distribution amplifier or passive splitter.
UNBALANCED CONNECTIONS
For unbalanced operation connect the mixer or preamplifier
directly to the RCA input by means of a standard unbalanced
RCA cable. Unbalanced connections employ one conductor to
pass the audio signal and a second conductor to act as both au-
dio common and shield. Unbalanced connections are susceptible
to radio frequency interference and electromagnetic interference
which may cause the speaker to hum, buzz or even rebroadcast
audio signals. For this reason, observe the following guidelines
when making unbalanced connections:
• Don’t use cables longer than 5m (15')
• Avoid running cables near electric motors, appliances,
television sets or other sources of electromagnetic
interference
• Ensure that the speakers and mixer, or preamplifier, are
all connected to the same AC power circuit to prevent
possible ground loops
OPERATION
Ensure that the power switch is in the OFF position before
connecting the power cable to the AC Input socket. Connect the
cable to a nearby AC Mains outlet and the then plug in the audio
input cable. Rotate the volume control counter-clockwise to the
minimum setting before switching the power on. Start the program
source and set the preamplifier or mixer gain to a nominal level.

Then, slowly increase the speaker’s level by turning the Volume
control counter-clockwise until the sound level is adequate for
the application.
TROUBLESHOOTING
NOTE: The Concourse Q6A and Q8A are not user-serviceable,
and no attempt should be made to repair or modify the electronics
in the field. Refer all service and repair to the nearest authorized
QUAD Industrial service center or directly to the QUAD Industrial
distributors sales office in your region.
In the event that the speaker does not power up, first check the
power outlet and the power cable. If power is present at the outlet,
REMOVE THE POWER CABLE FROM THE SPEAKER and check
the internal fuse that is mounted inside of the IEC receptacle on
the rear panel of the speaker. Use a small screwdriver to gently
remove the fuse holder and test the continuity of the fuse. Replace
the fuse with only the exact model and value printed on the rear
panel based on the voltage at which the speaker is set. Connect
the AC supply and switch on the speaker.
COMPLIANCE
This product is in compliance with CE directives and bears the CE
mark. For detailed information on specific directives please contact
your local QUAD Industrial sales office or distributor.
