Application Notes
The ARX Multi Q 6 Channel parametric Equalizer is a powerful and flexible tool for all
audio equalization requirements, equally at home in Studio work, Broadcast, fixed
installations or touring sound systems. Careful attention to circuit layout and shielding
has resulted in noise figures that make the Multi Q ideal for Digital applications.
Each channel of the Multi Q can be accessed individually, and has effective control
over virtually the complete audio spectrum, from 40 Hz to 16KHz.
Its exclusive and unique internal patching system lets you access up to 6 channels of
parametric EQ, either individually or in multiples.
What exactly does this mean? Here’s an example.
If you insert a lead into the Input of Channel 1, the signal will automatically be routed
through Channels 2 to 5 and come out at the Channel 6 Output, giving you a single
channel, 6 band equalizer.
If you pull the lead out of the Channel 6 Output and plug it into the Channel 3 Output,
the signal will stop there, giving you a single channel 3 band EQ. You can plug
another lead into Channel 4 Input and another into Channel 6 Output, giving you
another single channel 3 band EQ.
In this way, the Multi Q can be whatever you like: a single 6 band EQ, two 3 band
EQs, a 2 and a 4 band EQ, six one band EQs, any combination you need. All this at
the same time and without the need for extra patch leads.
All this makes the Multi Q a unique creative tool, because unlike other parametric
Equalizers you are not stuck with having to use 4 or 5 bands of EQ when you may
only need one or two. The Multi Q frees up these extra bands for use by other
applications needing EQ.
Front Panel Controls
• EQ In/Out switch. A hardwire Bypass of the EQ circuitry.
• Frequency x10 switch.
• Frequency select control. When used in conjunction with the x10 switch, gives a
range of centre frequencies from 40 Hz through to 16 KHz.
• ‘Q’ (Bandwidth) control, variable from 3 octaves through to 1/20th octave.
• Cut and Boost control, va/- 18 dB.
• Clip LED, indicating the onset of circuit overload.
• Numbered marker panel, for labelling EQ assigns.
Rear Panel Controls
• Tip/Ring/Sleeve Balanced Jack Input connector for Channel 1. Tip + Hot, Ring -
Cold, Sleeve Ground
• Tip/Ring/Sleeve Balanced Jack Output connector for Channel 2. Tip + Hot, Ring -
