Thank you for purchasing a Clockaudio product. We are confident that this product
will give you many years of trouble free operation.
As part of Clockaudio’s continual ongoing programme of product development,
improvements to the existing ARM microphone range including the ARM-C controller
have been made to further increase the already excellent reliability.

IMPORTANT INFORMATION
It is important not to connect the ARM V2 microphone to an existing ARM-C controller or an
existing ARM microphone to an ARM-C MK2 controller. It will not work.
The ARM V2 microphones can only be connected with ARM-C MK2 controllers.

ARM-C Control Unit Overview
The ARM-C controller allows a DSP to instruct up to 4 ARM microphones to be
raised or lowered. Up to four units can be daisy chained (using the Link to DSP input
connection). Thus allowing a DSP using a single control line to raise/lower up to 16
ARM microphones.
Supports 2 x RJ12 ports; one for DSP Input and one for Link which can be
used to connect to another ARM-
C’s DSP Input. A single command from a
DSP will simultaneously activate all connected ARM motorised microphones.
Supports 4 x RJ45 ports (M1
– M4) that allow for fast and easy connection of
4 x ARM motorized microphones. M1 and M2 on the front of the unit while M3
and M4 are on the rear of the unit.
A positive (+2.5V to +12V) signal applied at the DSP Input port will
simultaneously activate all ARM motorised microphones connected to the
control unit
’s M1 – M4 motor outlet ports.
Logic input to the DSP Input port shall be on pin 2 (Live); pin 1 is Gnd.
Removable Phoenix connector provides connection to an external 12V DC 2A
supply (ARM-PSU 1).
LED power indicator.
Flanges on the unit provide a simple screw fixing of ARM-C controller.
Warning
: Under no circumstances must any equipment
other than ARM V2 microphones be connected
to any of the M1
– M4 sockets of the ARM-C
MK2 controller unit. Serious damage will occur
to equipment and/or controller unit which is not
covered under warranty.

Installation
1. Install the ARM motorised microphone as per separate instructions given with
the product.
2. Ensure that the Control unit power supply is
NOT
switched on until all wiring
and connections have been completed.
3. Connect the ARM motorised microphone(s) to any of the M1
– M4 motor outlet
ports on the Control unit. It does not matter which port is used as they are all
connected in parallel.
4. Connect the DSP logic signal output terminals to the DSP input socket on the
ARM-C controller. Use the Link port for daisy chaining the connection to another
ARM-C controllers.
5. Connect the microphone audio output cable to the mixer / DSP.
6. Power up the DSP and check that it has been programmed to supply +2.5V to
12C logic high to ARM-C to raise the microphone.
7. The DSP should be programmed to mute the microphones whilst in the upward
or downward transition to prevent unwanted motor noise pickup. Typical
transition time is approximately 3 second.
8.
Connect the 12V DC power supply to the DC +/- input terminals of the Controller
unit observing the correct polarity
9. Switching on the DC supply to the ARM-C controller will illuminate the coloured
LED on the ARM-C. The motorised microphone may initially very slowly fully
extend and then retract. This is normal as it will be auto-calibrating.
10. When a logic high is received from a DSP, the microphone will raise and remain
raised until a logic low is received.
Warning
: Warning under no circumstances connect or
disconnect an ARM microphone with the
ARM C unit powered up. Failure to do so
may cause erratic operation.

Rear Panel
While the front of the unit provides DSP, Link, M1, M2 and power connections, the
rear panel provides connection for M3 and M4. The four ARM microphones can be
connected to any of the four connectors.
5.
Pinouts for RJ12 DSP/Cable
Off the shelf, readymade cables are freely available on the high street electrical retail
outlets. However if a cables are required to be handmade, then on the DSP input for
the ARM-C, pin 2 shall be used to provide the active signal (Live) while pin 1
provides the ground connection. None of the other pins are used.

Troubleshooting Guide
Microphone does not move
up or down
Check that the DSP control signal is present logic
+2.5 to 12 Volts is required.
Is the microphone motor cable connected?
Is the DC supply to the Controller unit switched on
blue power light should be illuminating?
Check logic input cable connections between DSP
and DSP control ports on the controller unit.
Disconnect and reconnect the power supply to the
controller unit.
Microphone is picking up
noise as it is being raised
or lowered.
This is normal. The microphone must be muted by
the DSP during the raising / lowering transitions.
Note it takes 3 seconds for the microphone to raise /
lower.
