It is possible to connect microphones (CH 1 to 3) or units with line level output (CH 1 to 5) to the five inputs. All inputs may be assigned to four PA zones independent of each other. A headphone output and a speaker output are provided to monitor the zone output signals. An additional line level input is provided for emergency announcements or other important announcements. A separate switch allows to switch to this input.8 English MONITORPHONESZ1 Z2Z3 Z4Z1 Z2Z3 Z4Z1 Z2Z3 Z4Z1 Z2Z3 Z4Z1 Z2Z3 Z4ZONE 1 ZONE 2ZONE 3 ZONE 4 MON 0 10ZONE SELECTOR0 10ZONE SELECTOR ZONE SELECTOR ZONE SELECTOR ZONE SELECTOR CH 2

4 Placing and Connecting theMixer The mixer is provided for installation into a rack for units with a width of 482 mm (19”) but it can also be used as a tabletop unit. For instal- lation into a rack, 3 RS (rack spaces) = 133 mm are required. Prior to connecting units or changing exist- ing connections, switch off the mixer and the units to be connected.

Up to three microphones with XLR plug or

6.3 mm plug may be connected to the inputs

CH 1 to CH 3 (25). Set the input level switches (24) to the corresponding position. Only actuate the switches when the amplifier is switched off or when the corresponding control LEVEL (3) is set to zero (switching noise). MIC for microphones which do not require phantom power PHANTOM for phantom-powered microphones Caution! Do not connect any microphones with unbalanced output when the phantom power has been activated. These microphones may be damaged.

4.2 Units with line output

Up to five units with a line output (e. g. CD player, cassette recorder, radio) may be con- nected to the inputs CH 1 to CH 5 (23 and 25). For background music, it is best to use the inputs CH 4 and CH 5. These inputs may be muted with a separate switch when e. g. an announcement is made via the input CH 1 (see chapter 4.4). The stereo signals fed to the jacks “L” and “R” of the inputs CH 4 and CH 5 are internally mixed to a mono signal. When connecting to the inputs CH 1 to CH 3, set the corresponding input level switch (24) to the position LINE. Only actuate the switch with the amplifier switched off (switch- ing noise). For connecting a stereo unit to the inputs CH 1 to CH 3, use one input each for the right stereo channel and the left stereo channel or use a stereo mono adapter (e. g. SMC-1 from MONACOR); otherwise, the signals of the ste- reo centre will cancel each other out.

4.3 Connection for emergency announce-

ments or a telephone systeme For emergency announcements or for con- nection to a telephone system, the amplifier is provided with the input TEL PAGING (20). T R G TEL. PAGING Signal Input and switch for emergency announcements Feed the signal (line level, 40 mV – 1.5 V) via a shielded audio cable to the terminal “R”. Connect the ground and the shield to the ter- minal “G”. Connect a switch to the terminals “T” and “G”. The switch is used to release the announcement, i. e. the announcement signal may always be available at the terminal “R”, but it can only be heard when the switch is closed. When the switch is closed, the signals of the inputs CH 2 – 5 can be muted at the same time, see chapter 5.1 Set the DIP switches ZONE (21) for the zones where the emergency announcements are to be heard to the lower position ON. The volume for these announcements is separately adjusted with the control VOLUME (22) on the rear side.

4.4 Switch for muting

the inputsCH 2 to CH 5 The inputs CH 2 to CH 5 can be muted together with a single switch, e. g. for making an im- portant announcement via the input CH 1. For this purpose, connect a switch to the terminals PRIORITY (19). Note: When an announcement is made via the input CH 1, the inputs CH 2 to CH 5 will be automatically muted if priority is given to the input CH 1, see chap- ter 5.1.

4.5 Power amplifiers for the speakers

Connect the power amplifiers for the speakers in the different PA zones to the balanced out- puts LINE OUT (26). If the input of the amplifier to be connected is unbalanced, only connect the input to the terminals “+” (signal) and “G” (ground). When connecting, the terminals can be removed from their plug-in connections for easier handling.

4.6 Monitor speaker and headphones

To be able to monitor the signals of the PA zones, it is possible to connect an 8 Ω speaker to the terminals MONITOR (18) and headphones to the jack PHONES (7).

4.7 Line output for another amplifier

orarecorder The line output MIX OUT (17) can be used to connect another amplifier or a recorder. At this output, the signal of the PA zone is available whose button MON (10) is pressed. If multiple zones are selected at the same time, the corre- sponding zone controls LEVEL (11) define the mixing ratio of the zone signals. Use this output:

2. To connect a recorder for recording the sig-

nals of a single zone or multiple zones.

Finally connect the supplied mains cable to the mains jack (14) first and then to a socket (230 V/ 50 Hz). To ensure continued operation of the mixer after a mains failure, connect a 24 V emer- gency power supply unit (e. g. PA-24ESP from MONACOR) to the screw terminals 24 V ⎓ (16). Note: When the 24 V voltage of the emergency power supply is available at the screw terminals 24 V ⎓, it will not be possible to switch off the mixer by means of the POWER switch (13). The mixer will automatically switch to emergency power supply in case of a mains failure or when it is switched off. 5 Setting into Operation

5.1 Giving priority to the inputs CH1

andTEL PAGING In the factory, the inputs CH 1 and TEL PAGING (20) are adjusted in such a way that their signals will be mixed with the other input channels. When the jumper S701 inside the amplifier is rearranged, the inputs CH 1 and TEL PAGING will take priority over the inputs CH 2 – 5. When an announcement is made via the input CH 1 or TEL PAGING, the signals of CH 2 – 5 will be automatically muted during the announcement. WARNING For rearranging the jumper S 701, the unit must be opened. Only skilled personnel may do this; inexpert handling may result in electric shock.

1) Disconnect the mains plug from the socket.

2) Unscrew the housing cover.

Rearrange the jumper S701 from OFF toON (figure at the bottom of page 9).

4) Fasten the housing cover again.9

5.2 Adjusting the volume and the sound,

switching the input signals tothezones

1) Prior to switching on the mixer for the first

time, set the four zone controls LEVEL (11) to zero to prevent an excessive volume at the beginning. Then switch on the unit with the POWER switch (13). The POWER indica- tor(12) lights up.

2) For basic setting of the input channels

set all controls GAIN (1), TREBLE and BASS (2) to mid-position, b) set all controls LEVEL (3, 11) to zero,

which is to be heard at highest volume (e. g. for an nounce ments) to approx.

∕3 of the maximum value. With the buttons ZONE SELECTOR (4), switch the input signal to the zones where it should be heard.

Switch on the power amplifiers for the speakers and adjust the desired volume for each zone with the zone controls LEVEL (11). The level indicators (9) show the volume of the zones. The top red LED should light up with passages of highest volume for a short time only. If it lights up for a longer time, turn back the corresponding zone control LEVEL. If the volume of the zones cannot be adjusted in an optimum way because the input signal is too low or too high, readjust the input level with the corresponding con- trol GAIN (1) or LEVEL (3).

Adjust the sound with the corresponding controls TREBLE and BASS (2). If required, re- adjust the volume with the control LEVEL(3).

6) For feeding further input signals to certain

zones, press the corresponding buttons ZONE SELECTOR (10). With these buttons the zones may be configured differently. Example: – The announcements of input CH 1 are to be heard in all zones. Press the buttons Z 1 to Z 4 of CH 1. – The announcements of input CH 2 are to be heard in zones 1 and 4 only. Press the buttons Z 1 and Z 4 of CH 2. – The background music of CH 4 is to be heard in zones 1 and 2. Press the buttons Z 1 and Z 2 of CH 4. – The background music of CH 5 is to be heard in zones 3 and 4. Press the buttons Z 3 and Z 4 of CH 5.

7) Adjust the volume and the sound of further

input signals with the controls LEVEL(3), TREBLE and BASS (2). Turn the controls LEVEL of the inputs not used to zero.

5.3 Muting the inputs CH 2 to CH 5

foranannouncement If a switch is connected to the terminals PRIOR- ITY (19), the inputs CH 2 to CH 5 can be muted at the same time by closing the switch. Thus, e. g. an important announcement can be heard via the input CH 1 without interference by other input signals.

5.4 Monitoring the zone signals

Press down the buttons MON (10) of the PA zones whose signals are to be monitored. Ad- just the volume for the monitor speaker con- nected to the terminals MONITOR (18) with the control MONITOR (8) and the volume for the headphones with the control PHONES (6). The signal for the monitor speaker is shown by the level indicator (5). Notes:

1. The volume for the headphones and the monitoring

speaker also depends on the zone controls LEVEL (11). When a control is set to zero, the signal of the corresponding zone cannot be monitored even if the button MON is pressed.

2. The buttons MON are also used to switch the
