1) Power switch: Here you can switch the power on and off.

2) Overload indicator: This red LED illuminates when one of the protections have been activated. No or

distorted sound will be heard. This will be in case of overheating, being the result of drawing too much

power from your amplier, or the impedance of the speaker lines connected are below the minimum load

impedance (see17).

3) Level indicators/clip-limit: A green LED will light after powering on. To work within normal conditions the vol-

ume indicator should be kept under 0dB (100%). At -2,5dB a limiter will be activated. This red LED indicates

that the “auto gain circuit” keeps the level below clipping. This is NOT a clip indicator, but an indication of

the “automatic gain control”.

4) Zone selectors: With these selectors you can activate the zone outputs. A green led at the left of the

switches will conrm that you have activated zone 1 to 3. For zone 4, two selectors are available. By means

of those two selectors you can decide to send background music only, spoken messages only, both or none

of them. Two yellow leds will conrm your selection. When you have selected the music only mode for zone

4, there will be silence during paging.

5) Master level control. Here you can adjust the desired volume of the overall signal.

6) Microphone 1 input: This balanced ¼” TRS phone jack has been wired in parallel with the other three input

options for microphone 1 at the back. For satisfying operation, use only one of these inputs at the time for

microphone 1. Microphone 1 can be given a priority over all other inputs by using the VOX priority (see 29).

7) Microphone 1 level control: Adjusts the volume of the microphone connected to one of the four input connec-

tors (1/4” jack, XLR3 combo jack, DIN5 or euro block).

8) Microphone 2 3 level control: By turning each control clockwise the desired level of that input in the total mix

is set. To decrease these levels, turn counter-clockwise. The volumes of the inputs not in use, should be set

fully counter-clockwise. If not, hiss might occur.

9) Microphone 4 / line 4 level control: Adjusts the input signal of the microphone connected to the XLR combo

jack at the back or the line source connected to stereo RCA input 4.

10) “Muted by priority” led: This red led will blink when any priority status has been activated.

11) Music level control: Here you can adjust the level of the line source selected.

12) Line source selector: Select the desired music source to be heard (AUX, CD or TUNER).

13) Bass control: Adjust as per your taste. In reverberant rooms intelligibility can be increased by decreasing

bass. The centre position gives you a at response.

14) Treble control: Adjust the level as per your taste or needs. Adding high frequencies gives brilliance to your

sound. High frequency feedback can be removed by decreasing treble. The centre position gives you a at

response.
