No guarantee claims for the unit and no li- ability for any resulting personal damage or material damage will be accepted if the unit is used for other purposes than originally intended, if it is not correctly connected or operated, or if it is not repaired in an expert way. If the unit is to be put out of opera- tion definitively, dispose of the unit in accordance with local regulations. 3 Applications This amplifier has specially been designed for setting up a PA system in which individ- ual 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 482 mm (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 = 89 mm). 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 dissipa- tion, install a ventilation unit (e. g. DPVEN-04) into the rack.11 English 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 correspond- ing screw terminal strips for the green plug-in connections (17, 19, 20).

To avoid switching noise, first switch on all the other units of the PA system.

Before first-time operation of the amplifier, set the volume controls ZONE (8) to mini- mum 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.

When a microphone for announce- ments in all zones has been connected to the input CH 1, set the switch TALK- OVER (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 an- nouncements in all zones, set the switch TALKOVER to the position OFF.

Activate or deactivate the phantom power supply for the microphone in- puts MIC (24). Caution! There may be loud switch- ing noise while the phantom power supply is being activated or deacti- vated. 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 phan- tom 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 phan- tom power have been connected to the inputs CH 2 – 4, set the switch PHAN- TOM 2-4 (25) to the position ON; in all other cases, set the switch to the position OFF.

Turn the volume control CH .. (2) of the input to be reproduced at the highest vol- ume to approx. ²∕3 of its maximum. Use the zone buttons Z .. (4) to switch the input signal to the zones in which it is to be audible.

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 sig- nal 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 accord- ingly. The LED indicator CLIP may only light up briefly for signal peaks.

To route additional input signals to spe

ume of the other input signals. Turn the controls of the inputs not used to mini- mum.

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.12 English 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 fre- quencies. 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

thezones If other signals than the ones currently se- lected are to be audible in the zone:

1) In all input channels, disengage the corre-

sponding zone button Z .. (4) for the zone (e. g. to change the selection for zone 2, disengage the buttons Z 2). Thus, all sig- nals for the zone are deselected for the time being.

Press the zone buttons Z .. in the input channels whose signals are to be audible in the zone.

If required, readjust the volume for the zone by means of the corresponding con- trol ZONE (8).

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 pos- sible 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:

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.

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 ampli- fier 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 announce- ment 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.

Press the button CHIME (40) if the an- nouncement is to be preceded by a chime tone.

To make an announcement, keep the but- ton 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 accord

ingly, speak at a higher volume or reduce the distance to the microphone.

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

furtherannouncements

1) Select the zones by means of the buttons

2) Set the sliding switch (34) to the position

LOCK. It will not be possible to change the zone selection.

To make an announcement, keep the but- ton TALK (41) pressed. When the button TALK is released, the zone selection will remain saved, the corresponding zone but- tons 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

2) Use the buttons (38, 39) to select and de-

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.

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 in- dicator 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 but- ton; the LED indicator ACTIVE will light up in green.

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.

If the amplifier stage of a zone is overheated or overloaded, the protective circuit will inter- rupt 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 indica- tor PROT fails to extinguish after the amplifier stage has cooled down, ask skilled personnel to find and eliminate the fault.13 English 8 Specifications Amplifier PA-M224 PA-M412 Number of input channels 8 8 Number of zones 2 4 Rated output power 2 × 240 W 4 × 120 W THD < 1 % < 1 % Zone outputs Connection 2 × speaker 100 V 2 × line signal Screw terminals 4 × speaker 100 V 4 × line signal Screw terminals Phantom power supply for Mic CH 1 – 4 24 V 24 V Inputs Mic CH 1 – 4 Line CH 1 – 4 Line CH 5 – 8 Input sensitivity/ Impedance; connection
