6.3 mm jacks MIC 1 and MIC 2 for micro-

phones 2 Safety Notes This unit corresponds to all relevant directives of the EU and is therefore marked with . WARNING The unit is supplied with hazardous mains voltage. Leave servic ing to skilled personnel only. Never insert anything into the air vents. Inex- pert handling may result in electric shock. During operation, there is a hazard of contact with a dangerous voltage of up to 100 V at the speaker terminals (10). Never operate the ampli- fier without the protective cover (11).

The unit is suitable for indoor use only. Protect it against dripping water, splash water and high air humidity. The admissible ambient tempera- ture range is 0 – 40 °C.

Do not place any vessel filled with liquid on the unit, e. g. a drinking glass.

The heat generated within the unit must be dissipated by air circulation. Never cover the air vents.

Do not operate the unit or immediately discon- nect it from the power supply:

if there is visible damage to the unit or to the mains cable,

if a defect might have occurred after the unit was dropped or suffered a similar accident,

3. if malfunctions occur.

In any case the unit must be repaired by skilled personnel.

A damaged mains cable must only be replaced by skilled personnel.

Never pull the mains cable when disconnecting the mains plug from the socket, always seize the plug.

For cleaning only use a dry, soft cloth; never use chemicals or water.

No guarantee claims for the unit or liability 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.

Important for UK Customers! The wires in this mains lead are coloured in accord ance with the following code:8 English green / yellow = earth blue = neutral brown = live As the colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the ter minals in your plug, proceed as follows:

The wire which is coloured green and yellow must be connected to the terminal in the plug which is marked with the letter E or by the earth symbol ⏚ or coloured green or green and yellow.

The wire which is coloured blue must be con- nected to the terminal which is marked with the letter N or coloured black.

3. The wire which is coloured brown must be

con nected to the terminal which is marked with the letter L or coloured red. Warning – This appliance must be earthed. If the unit is to be put out of operation definitively, take it to a local recycling plant for a disposal which is not harmful to the environment. 3 Applications The amplifier PA-704 provides a maximum out- put power of 70 W and is specially designed for small PA systems. 100 V speakers, 70 V speakers or low-impedance speakers can be used (please refer to the examples on page 3). For the connection of audio sources, 4inputs are available: 2 microphone inputs 1 input for audio units, such as CD / MP3 player, radio or tape deck 1 input for turntables with magnetic system 4 Setup Options When setting up the amplifier, make sure that the cooling fins are not covered and that air will be able to flow freely to ensure sufficient cooling. 5 Connecting the Amplifier The inputs and speakers may only be connected when the unit is switched off!

AUX (13) Connection for a unit with line output, e. g. CD / MP3 player, tape deck or turntable with ceramic system PHONO (14) Connection for a turntable with magnetic system MIC 1 and 2 (15) Connections for low-imped- ance microphones

Numerous connections, e. g. those for the speak- ers, are underneath the protective cover (11). For connection, unscrew the cover. WARNING Do not operate the amplifier with- out the protective cover (11). During operation, there is a hazard of con- tact with a dangerous voltage of up to 100 V at the speaker terminals (10). After con- necting, screw on the cover again so that the terminals are protected against any accidental contact. The speakers can be connected as shown in figs.3 and 4. Connect them to the screw terminals(10) accordingly. When connecting, observe the cor- rect individual or total impedance of the speakers and their correct polarity (positive and negative connections as shown in figs. 3 and 4). The pos- itive connection of the speaker cable is always specially marked. Attention! When PA speakers with 70 V or 100 V audio transformers (fig. 3) are used, the total load of all speakers must not exceed 35 W RMS; otherwise, the amplifier will be overloaded and may be damaged.9 English

A priority switch (NO contact) can be connected to the screw terminals PRIORITY (9). Channels MIC 2, PHONO and AUX are faded out while this priority switch is pressed so that only an nounce- ments via MIC 1 can be heard. After releasing the priority switch, channels MIC 2, PHONO and AUX are faded in again.

1) Finally, connect the amplifier by means of the

mains cable(8) to a mains socket (230 V/50 Hz).

2) To ensure continued operation of the amplifier

in case of a mains failure, connect an emer- gency power supply unit (e. g. PA-24ESP from MONACOR) to the terminals 12 – 24 V⎓ (12). Note: If the voltage from the emergency power sup-ply unit is present at the terminals 12 – 24 V⎓, the amplifier cannot be switched off with the switch POWER (6). In case of a mains failure or if it is switched off, the amplifier will switch automatically to the emergency power supply. 6 Operation

Turn the control for the total volume (5) to zero before switching on. Switch on the amplifier via the POWER switch (6).

Slightly turn up the control for the total vol- ume(5). Adjust the desired volume in relation to each other via the controls MIC 1, MIC 2 (1), PHONO (2) and AUX (3). Set all controls which are not connected to a source to zero.

3) Adjust the tone with the controls (4) BASS and

TREBLE and the volume with the control for the total volume (5).

If desired, fade the microphones in and out with the controls MIC 1 and MIC 2 (1) as well as the music sources with the controls PHONO (2) and AUX (3).
