2.6 Voice activation

The voice activation (VOX) of audio input 2 can be switched on and off with the MIX/VOX switch (26).

MIX

VOX

If the switch is set to VOX, audio signals of input 2 override the audio signals of input 1. The audio signals of input 1

and input 2 are mixed if the switch is set to MIX.

2.7 Using the priority input (22)

You can use the priority input to connect the induction loop amplifier with a alarm system or a PA-system. The

priority of the priority input is higher than the one of the audio inputs. The signal on the connected induction loop

is replaced with the signal of the priority input if a signal is received at the priority input. Please use the volume

control to set the volume of the audio signal which the priority input sends to the connected induction loop.

PRIORITY

100V

INPUT

10k

Important note

Put the safety bracket on the priority input to make sure that it is not possible

to touch the priority input.

2.8 Fault output

You can send the condition of the loop amplifier to an external devices (e.g. siren) with the voltage-free fault out-

put (15). The fault output is an internal relay. Normally closed "NC" is connected to "COM" by default. The relay

connects normally open "NO" to "COM" if a supervised function of the amplifer has failed.

2.9 Line output

You can connect a recording device (e.g., a tape deck) to the line output (17) of the loop amplifier.

LINE OUT

2.10 Power supply (21)

The PROLOOP DCCplus induction loop amplifier can be used in countries with 110 V or 230 V mains power

supply.

To connect the amplifier with the mains power supply please do the following steps:

1. Set the voltage selector (20) to the correct position.

Position "115" for countries with 100 to 120 V (AC) or Position "230" for countries with 220 to 240 V (AC).

Note

The voltage selector is set on "230" position when the PROLOOP DCCplus induction loop amplifier is

delivered.
