Connect Power (model dependent)
Connect the mains lead (supplied) to a 230Va.c. wall socket and the
amplifier‘s 230Va.c. connector.
Switch on power and the amplifier will be unlocked and show the
Line Input
menu display.
5
Set up the Amplifier’s Inputs
Note:
By default, all inputs to the amplifier are factory set to their lowest settings.
Activate all relevant audio input source(s), i.e. mic., line in, outreach, optical (model dependent).
Select the relevant display, e.g.
Line Input
, and use the
Up
4
control button to adjust
the signal level until the
Limit
indicator flashes occasionally, as shown below.
6
Set up the Loop Drives
Select the
Loop Drive 1
display and use the
Up
4
control button to increase the loop
field strength, as shown below. For dual loop amplifiers, select the
Loop Drive 2
display
and repeat this procedure.
7
Metal Compensation
For applications with high metal content in, or near, the hearing loop, select the
amplifier’s
Metal Comp
display. Increase the metal compensation by small increments
using the
Up
4
control button until a natural balance is achieved.
Note:
If high metal content is present, the amplifier’s area of coverage will be reduced,
and further reduced, as the
Metal Compensation
level is increased.
Repeat this procedure by selecting the relevant display and adjusting the signal level. If
a microphone is used, enable
Phantom
on the display. Also, enable
Phase Shift
(model
dependent) on the display for phased array systems.
