ARCHITECTS’ AND ENGINEERS’ SPECIFICATIONS
The signal processor shall be mounted in a steel chassis six inches (150mm) deep and one rack unit
high. The unit shall be a Zoner/Mixer, i.e, it shall accept inputs from four separate stereo sources as
well as a microphone, and send them to two separate zones.
The microphone input shall have a level control and three way Equalisation controls. The micro-
phone connector shall be a balanced XLR input with an Input impedance of 4 K Ohms. There shall
also be an input for a ducker control to attenuate line inputs by 20 dB, and LEDs to indicate micro-
phone status. The microphone shall be able to be routed to either or both output zones.
Each Line source shall have High Z Left and Right phono (RCA type) connectors, with associated
Gain trim controls –10dB to +10 dB on the rear panel. A switch and status LED on the front panel
shall indicate which source is active in each zone. These switches shall be interlocking so that only
one of the four input sources per zone can be selected at one time.
• Microphone Zone assign switches and LEDs
• Microphone Level control
• 3 way EQ controls for the microphone
• Zone A program source switches, with label panels and LED
indicators to show active source
• Zone A 2 way EQ controls
• Zone A Remote control status LED
• Zone A Master Level control
• Zone A and B Output Level LED metering
(
Zone B functions identical to Zone A)
• IEC 3 pin AC connector and integral fuseholder. Replace fuse with correct
value only: 100 - 120 V AC 1 amp, 220-240 V AC 0.5 amp. Please also
refer to voltage details on Page 2
• Zone A and B Balanced XLR Outputs wired Pin 1 Ground, Pin 2+ (Hot), Pin
3 – (Cold)
• Remote Master Zone Output connectors
• Sources 1, 2, 3 and 4 Input Gain trim controls
• Sources 1, 2, 3 and 4 Phono (RCA type) input connectors
• Balanced XLR microphone connector
• Microphone Gain trim control
• TRS jack connector for Mic override (Press-to-talk ducker) to attenuate line inputs by
20 dB. Wired so shorting Tip and Ring enables ducker
Each Zone shall have two-way Equalisation and the option of fitting a VCA controlled Remote
Master output level control. Each Master output shall have a dedicated 5 LED metering display
Input source impedance shall be 100K Ohms, and the input headroom shall be +21dB. The fre-
quency response (all channels and masters) shall be 20 Hz to 20 KHz, ±0.4dB. The Output imped-
ance shall be 300 ohms balanced, and the maximum Output level shall be +21dB, with a Signal to
Noise ratio at unity of -90 dB ‘A’ weighted. Output connectors shall be Balanced XLR type. THD
shall be below .005%, 100Hz to 10 KHZ, and the unit shall have a dynamic range of 111dB.
Power shall be supplied via a removable mains cable, connecting to an IEC connector with an inte-
gral fuse and voltage change switch on the unit’s rear panel.
The Zoner/Mixer shall be the ARX BarMIX.
