페이지 인쇄1.1.1 Description of the indicators, controls and connectors at the front panel
(1)
Power supply indicator: The green LED goes on if the induction loop amplifier is switched on.
(2)
VU indicator: It shows the master VU level. 0 dB (red LED), -6 and -12 dB (yellow LED)
(3)
Level indicator for induction loop power: It shows the electrical current throught the loop.
(4)
Fault indicator: Shows a failed supervised function of the loop amplifier.
(5)
ON/OFF Switch: The loop amplifier is switched on and off with this switch.
(6)
Regulator to set the corresponding input sensitivity: Sets the input sensitivity of input IN1 and input IN2.
(7)
Bass control: Controls the low tones of the audio signal.
(8)
Treble control: Controls the high tones of the audio signal.
(9)
Loop integrity indicator: The LED is on if the connected loop is not broken.
(10)
Limiter indicator: The LED is on if the limiter is active.
(11)
AGC indicator: The LED is on if the automatic gain control (AGC) is active.
(12)
Power control: With this control you set the maximum electrical current of the induction loop.
(13)
Earphone jack: You can connect headphones to the amplifier.
1.2.1 Description of the indicators, controls and connectors at the rear panel
(14)
Fan outlet: Please do not cover it so that any heat generated by the device can be dissipated.
(15)
Fault output: Gives the status of the loop amplifier to other equipment.
(16)
Supervision switch: Switchs the supervision of the priority input on and off.
(17)
Line out: Connection for a external recording unit.
(18)
Metal loss compensation: Sets the metal loss compensation.
(19)
Master/Slave connection sockets: Connect master and slave amplifiers to this amplifier.
(20)

(21)
Power supply (110/230V / 50/60Hz): Connection for mains power supply.
(22)
Priority input: Connection for systems which can override the audio signal on the induction loop.
For example a alarm system or a PA-system.
(23)
10k/5k selection switch: You can select the frequency range of the audio signal on the amplifier.
(24)
AGC/LIMITER Switch: You can select the automatic gain control (AGC) or the limiter.
(25)
AGC control regulator: Regulats the range of the automatic gain control.
(26)
MIX/VOX Switch: Select if an audio signal of input 2 should override an audio signal of input 1 or if both
audio signals are mixed.
(27)
Audio inputs: Connection for external audio sources.
(28)
Screw terminal for the connection of the loop: The both ends of the loop cable will be connected here.
(29)
Screw for earth connection: Connects the loop amplifier to earth.
