7. OPERATION
1
Prior to switching on, turn down the master controls MAIN and MONITOR for the overall level to the left
stop position to avoid a possible switching-on noise.
2
First switch on the connected audio sources, then the
PAM-500 MK2
PA system. The power
indicator lights green. After operation switch off the PA system first.
3
Select the operating mode with the selector switch MODE:
• MAIN STEREO: Operation with both speakers. The stereo master signal is available at the speaker
outputs.
• MAIN/MONITOR: Operation with a separate monitor speaker. At the speaker output MAIN LEFT/MAIN,
the mono master signal is available; at the output MAIN RIGHT/MONITOR, the monitor signal mixed via
the controls AUX.
4
First set all level controls, effect controls and tone controls of all input channels, the VIP control and the
total effect control DSP/AUX to 0.
5
Adjust the master controls MAIN and MONITOR for the overall volume to a level that the subsequent
adjustments can be heard well via the speakers.
6
Adjust the desired volume ratio of the input channels with the LEVEL controls. Turn the controls of the
inputs not used to 0.
Do not direct any microphones to the speakers. This can result in dangerous and unpleasant acoustic
feedback which will generate a loud whistling sound.
7
Adjust the desired sound for each input channel with the tone controls. By adjusting the tone controls,
the high frequencies (control HIGH), the mid frequencies (control MID) and the low frequencies (control
LO)W can be boosted or attenuated. With the controls in mid-position, the frequency response is not
affected.
7
Use the panorama control PAN for the mono channels, to place the mono signals in the stereo sound of
the master signal and for the stereo channels to adjust the balance of the stereo signals.
8
With the 10-band equalizer, adjust the sound for the master signal as desired.
9
Determine the definite level for the master volume of the PA system with the master controls MAIN and
MONITOR. In case of overload the red LEDs CLIP light up.
7.1 Adding Effects
An echo effect created via the integrated effect processor can be added to the signal of each input channel.
The signal of an effect unit connected to the jacks REV/AUX SEND and STEREO AUX RETURN is added in
parallel.
1
With the controls AUX, adjust the signal part for each channel which is to be fed to the internal effect
processor and to an external effect unit. The further the control is advanced, the more powerful is the
effect for the channel. The effect level is also dependent on the channel volume adjusted with the
control LEVEL.
2
With the control AUX in the effect section, adjust the total volume of the internal effect.
3
With the control PAN in the effect section, adjust the position of the internal effect in the stereo
panorama of the master signal.
4
For the internal echo effect, adjust the delay time with the control DELAY and the number of repeats
with the control REPEAT.
5
With a foot switch connected, it can be used to switch on and off the internal effect.
6
In the operating mode MAIN/MONITOR, the signal part of the corresponding channel in the monitor is
adjusted at the same time as the effect part by means of the control AUX. However, the effect is only
fed to the mono master signal, not to the monitor signal.
7.2 Priority
Function
To improve the audibility of an announcement input channel 1 is equipped with an adjustable priority function
which automatically attenuates the volume of all other signals. Adjust the degree of the level attenuation with
the control VIP. With the control set to 0, the function is deactivated.
