Q SERIES USER MANUAL 2

1. Features and Specifications (Amplified Cabinet):

The Q12a is a 12” coaxial, full range loudspeaker cabinet which has been designed for
optimal performance and flexibility within its intended application as a compact musicians
backline and pa loudspeaker. This section covers the usage of the amplified cabinet modes,
providing the user with a self contained, compact, precise, light weight solution.

The design was conceived with considerable consultation with customers and we welcome
any comments and suggestions you may have in our continual quest to bring you the products
you want to use.

Loudspeaker features:

• Optimised for Guitar Sound Reproduction With Cabinet Simulation Pre-amps.

Also suitable for use for monitoring keyboards, vocals and other sources at the users

discretion.

.

• Coaxial 12” Driver – Providing a Large and Unchanging Sweet Spot of Sound.

This cabinet contains a coaxial loudspeaker – a single driver incorporating a tweeter
driver and paper cone driver designed specifically to work together into a single, constant
directivity, spherical point source. This offers the unique advantage of of a sound-field which
does not significantly change in tonal characteristic wherever the user chooses to listen to
the cabinet off axis by up to 40 degrees (a total sound-field span of 80 degrees) both
horizontally and vertically. The sound dispersion diagram below illustrates this behaviour.

Cabinet produces a wide sweet spot in both planes for faithful reproduction over a wide area.

• Multiple Orientation Cabinet Design - May be used horizontally or vertically.

• The cabinet also allows mounting on a speaker stand via built in 38mm pole

receptacle.

The design of the cabinet allows for use in Horizontal, Vertical and speaker stand
mounted Vertical configurations and also has interlocking feet for easy, secure stacking of
multiple cabinets.
The cabinet orientation diagram below illustrates some possible configurations.

2. Amplifier Feature Overview:

(1) Power Switch

This switch controls the power supply to the amplifier. There is a short delay on power-up;

this is to avoid the switch-on "thump" which could damage the loudspeakers.

.

(2) Gain Control

The level trim for the amplifier is set via this control.

Rotating the knob fully clockwise, results in no attenuation to the incoming audio signals.
