3 Applications
This amplifier has specially been designed for setting up a PA system in which individual areas or rooms (zones) can be provided with sound in different ways. The signals of eight different audio sources (microphones, MP3/ CD player, radio, etc.) can be routed as desired to two zones (with the amplifier PA-M224) or to four zones (with the amplifier PA-M412). For each zone, the volume and the sound can be adjusted differently as required.
The wall module PA-M1WP (accessory) can be used to adjust the volume directly in a zone. It is possible to connect a microphone or an MP3 player, for example, to the wall module so that, instead of the signal source selected at the amplifier, the microphone/MP3 player is audible in the zone.
By means of the zone paging microphone PA-M4RC (accessory), announcements can be made in a specific zone or in all zones.
4 Setting up the Amplifier
The amplifier is designed for installation into a rack for units of a width of 482mm (19") but can also be used as a tabletop unit. In order to ensure sufficient cooling of the amplifier, air must always be able to flow freely through all air vents.
4.1 Rack installation
For rack installation, the amplifier requires 2 RS (2 rack spaces = 89mm .To prevent the rack from becoming top-heavy, insert the amplifier into the lower section of the rack. The front plate is not sufficient for fixing the amplifier safely; additionally use lateral rails or a bottom plate to secure the amplifier.
The hot air given off by the amplifier must be dissipated from the rack; otherwise heat will accumulate in the rack which may not only damage the amplifier but also other units in the rack. In case of insufficient heat dissipation, install a ventilation unit (e.g. DPVEN-04) into the rack.
5 Connecting the Amplifier
Connections should only be made by skilled personnel. Always switch off the amplifier before making any connection!
The amplifier is supplied with the corresponding screw terminal strips for the green plug-in connections (17, 19, 20).

6 Basic Settings
1) To avoid switching noise, first switch on all the other units of the PA system.
2) Before first-time operation of the amplifier, set the volume controls ZONE (8) to minimum to make sure that the volume will not be too high after switch-on. Then switch on the amplifier by means of the POWER switch (13). The LED indicator POWER will light up.
3) For basic setting of the input channels:
a) Turn all controls GAIN (21), HIGH, MID and LOW (1) to mid-position.
b) Turn all volume controls CH .. (2) to minimum.
c) Disengage all zone buttons Z... (4).
d) When a microphone for announcements in all zones has been connected to the input CH 1, set the switch TALKOVER (26) to the position ON. Thus, while an announcement is being made, all other inputs will be muted and the announcement will be routed to all zones; the zone buttons Z .. (4) in the input CH 1 will have no function. If the input CH 1 is not used for announcements in all zones, set the switch TALKOVER to the position OFF.
e) Activate or deactivate the phantom power supply for the microphone inputs MIC (24).
Caution! There may be loud switching noise while the phantom power supply is being activated or deactivated. Therefore, set the volume controls ZONE (8), for example, to minimum first.
Never connect a microphone with an unbalanced output to an input where the phantom power supply has been activated. The microphone may be damaged.
When a microphone that requires phantom power has been connected to the input CH 1, set the switch PHANTOM (27) to the position ON; in all other cases, set the switch to the position OFF.
When microphones that require phantom power have been connected to the inputs CH 2-4, set the switch PHANTOM 2-4 (25) to the position ON; in all other cases, set the switch to the position OFF.
4) Turn the volume control CH .. (2) of the input to be reproduced at the highest volume to approx. 13 of its maximum. Use the zone buttons Z .. (4) to switch the input signal to the zones in which it is to be audible.
5) Use the controls ZONE (8) to adjust the volume desired for each zone. The level indicators (6) will indicate the volume of the zones. The yellow LED indicator CLIP should only light up briefly for signal peaks. If it lights up more frequently, turn back the corresponding control ZONE accordingly.
If the volume of the input signal is too low or too high so that it is not possible to adjust the volume of the zone in an optimum manner, readjust the input level by means of the corresponding control GAIN (21) or CH ... (2). If the LED indicator CLIP (3) in an input channel lights up more frequently, the input is overloaded. In this case, turn back the control GAIN accordingly. The LED indicator CLIP may only light up briefly for signal peaks.
6) To route additional input signals to specific zones, press the corresponding zone buttons Z... (4).
7) Use the buttons CH .. (2) to adjust the volume of the other input signals. Turn the controls of the inputs not used to minimum.
8) Use the controls HIGH, MID and LOW (1) to adjust the sound of the input signals in the channels CH 1-4.
Use the controls HIGH and LOW (5) to match the sound in the individual zones to the respective room acoustics.
7 Operation
7.1 Adjusting volume and sound
To increase or reduce the volume for a zone, turn the corresponding control ZONE (8) up or down. To readjust the sound for a zone, use the corresponding controls (5): HIGH for the high frequencies, LOW for the low frequencies.
If the volume of an input signal is too high or low in relation to the volume of other input signals, readjust the volume by means of the corresponding control CH .. (2). The sound of an input signal in the channels CH 1 - 4 can be adjusted by means of the controls HIGH, MID and LOW (1).
Important: The settings for an input signal will apply to all zones to which the input signal has been switched.
7.2 Changing input signals for the zones
If other signals than the ones currently selected are to be audible in the zone:
1) In all input channels, disengage the corresponding zone button Z... (4) for the zone e.g. to change the selection for zone 2, disengage the buttons Z 2). Thus, all signals for the zone are deselected for the time being.
2) Press the zone buttons Z .. in the input channels whose signals are to be audible in the zone.
3) If required, readjust the volume for the zone by means of the corresponding control ZONE (8).
7.3 Muting zones
If a zone is not to be provided with sound (e.g. during intervals or at the end of an event), the sound can be muted by means of the corresponding button MUTE (7).
Muting the sound of a zone can also be useful when input signals are being selected: Even when the sound of a zone is muted, the sound can be monitored via the monitor speaker (12), see chapter 7.4. Thus it is possible to make tests by switching input signals to a zone without them being audible there.
7.4 Monitoring zone signals
A monitor speaker (12) is available so that zone signals can be directly monitored at the amplifier:
1) Use the switch PFL/AFL (9) to make the appropriate selection:
PFL = The zone signals will be audible via the monitor speaker even when the button MUTE (7) is pressed or when the volume control ZONE (8) is set to minimum.
AFL = The signals will be audible according to the zone volume adjusted.
2) Engage the zone button Z ... (10) of the zone to be monitored. Disengage the other zone buttons (10).
3) Use the control MONITOR (11) to adjust the volume for the monitor speaker.
7.5 Zone paging microphone PA-M4RC
Connect the microphone to the amplifier and then, to make the basic settings, turn the control (32) on the rear of the microphone to mid-position and set the sliding switch (34) to the position UNLOCK. As soon as the amplifier is switched on, the LED indicator POWER (36) will light up.
1) First use the zone buttons 1 ... 4 (39) to select the zones in which the announcement shall be audible. To select all zones, press the button ALL (38); to deselect a zone, press a button again.
Note: Please note the different lettering of the microphone for the zones: the digits 1 and 2 to the left of the buttons apply to the amplifier PA-M224, the digits 1 - 4 to the right of the buttons apply to the amplifier PA-M412.
2) Press the button CHIME (40) if the announcement is to be preceded by a chime tone.
3) To make an announcement, keep the button TALK (41) pressed, wait for the chime tone (if applicable) and then speak into the microphone. The LED indicator CLIP (35) should only light up briefly. If it lights up more frequently, turn the control (32) counter-clockwise accordingly, speak at a lower volume or increase the distance to the microphone.
If the volume of the announcement is too low, turn the control clockwise accordingly, speak at a higher volume or reduce the distance to the microphone.
4) After the announcement, release the button TALK; the zone selection will be deleted; the zones must be selected again for the next announcement.
Note: Announcements made via the zone paging microphone will take priority over other signals and will interrupt them.
7.5.1 Saving a zone selection for further announcements
1) Select the zones by means of the buttons (38, 39).
2) Set the sliding switch (34) to the position LOCK. It will not be possible to change the zone selection.
3) To make an announcement, keep the button TALK (41) pressed. When the button TALK is released, the zone selection will remain saved, the corresponding zone buttons will remain illuminated. The selection will also remain saved when the amplifier is switched off.
To change a zone selection saved:
1) Set the sliding switch (34) to the position UNLOCK.
2) Use the buttons (38, 39) to select and deselect zones.
3) To save a zone selection changed, set the sliding switch (34) to the position LOCK again.
7.6 Wall module PA-M1WP
As soon as the module is connected to the amplifier and the amplifier is switched on, the LED indicator ACTIVE of the module will light up.
1) Use the button (28) of the module to make the appropriate selection:
- The signals of a microphone or audio unit (CD player, radio, etc.) connected to the module are to be audible in the zone: Engage the button; the LED indicator ACTIVE will light up in yellow.
- The signals selected at the amplifier by means of the buttons Z .. (4) are to be audible in the zone: Disengage the button; the LED indicator ACTIVE will light up in green.
2) Use the control VOL (30) to adjust the volume for the zone. If it is not possible to adjust a sufficiently high volume, turn up the corresponding control ZONE (8) at the amplifier which defines the maximum volume possible.
7.7 Malfunctions
If the amplifier stage of a zone is overheated or overloaded, the protective circuit will interrupt the signal path to the speaker terminal SPEAKER (20) in this zone. In this case, no signal will be audible in the zone and the corresponding LED indicator PROT (6) will light up.
Use the corresponding control ZONE (8) to reduce the zone volume. If the LED indicator PROT fails to extinguish after the amplifier stage has cooled down, ask skilled personnel to find and eliminate the fault.
