Unika AR3600I, User Instructions

REMOTE/DELAYED OPERATION

It is possible to control one or a group of remotely located AR3600Is using wiring 
carrying only a low control voltage. This can be very convenient in certain situations; 
for example, turning on amplifiers on a stage from a sound booth in the rear of a hall. 
The control signal can be safely routed through wiring no heavier than an unused 
microphone line. The control signal is DC, so it will not cause noise in adjacent audio 
lines. The necessary voltages are generated internally in the AR3600I; all that is 
needed is wiring and a SPST switch. 

All connections for remote operation are made through the screw terminal strip on 
the rear panel. 

There are three recommended configurations:

Single AR3600I, local turn-on only: Turn-on/off is with the Power switch on the front 
panel. No wires or jumpers should be connected to the terminal strip.

Single AR3600I, remote turn-on: Connect a switch between the Remote Out and 
Remote In terminals. Leave the front panel Power switch in the ON position. When 
the switch is open, the AR3600I is on; when closed, the AR3600I, is off.

Multiple AR3600Is, remote turn-on in delayed sequence: A built-in delay of 
approximately a quarter second is automatically provided to stagger the potentially 
large inrush currents that occur when certain types of equipment are powered up 
simultaneously. Using such a delayed sequence can avoid blowing a house breaker 
when all the AR3600Is are powered from the same circuit.

To create a remote delayed sequence, all front panel Power switches must be left in 
the ON position. All Ground terminals must be connected together. The Delay Out of 
the first AR3600I (the one that will turn on first) is connected to the Remote Out of 
the second unit. The Delay Out of the second AR3600I is connected to the Remote 
Out of the third unit, and so forth for additional units.

The master on-off switch must be connected to the Remote In and Remote Out 
terminals of the first unit. See the following illustration.

The diagram above illustrates a set of three AR3600Is 
connected for remote turn-on in delayed sequence. When 
the switch is opened, unit 1 turns on after 3 seconds. Unit 
2 turns on a quarter second later, and unit 3 turns on a 
quarter second after unit 2.
