UNPACKING INSTRUCTION

CAUTION! Immediately upon receiving the product, carefully unpack the carton, check the contents to ensure that all parts are present, and have been received in good condition. Notify the shipper immediately and retain packing material for inspection if any parts appear damage from shipping or the package itself shows signs of mishandling. Save the package and all packing materials. In the event that the product must be returned to the factory, it is important that the product be returned in the original factory box and packing. If the device has been exposed to drastic temperature fluctuation (e.g. after transportation), do not switch it on immediately. The arising condensation water might damage your device. Leave the device switched off until it has reached room temperature

POWERSUPPLY

On the label on the backside of the product is indicated on this type of power supply must be connected. Check that the mains voltage corresponds to this, all other voltages than specified, the light effect can be irreparably damaged. The product must also be directly connected to the mains and may be used. No dimmer or adjustable power supply.

Always connect the device to a protected circuit (circuit breaker or fuse). Make sure the device has an appropriate electrical ground to avoid the risk of electrocution or fire.

For 100V line systems, connect the amplifier to the first speaker in the system using double-insulated speaker wire which has adequate current rating to handle the total output of the amplifier.

Connect the “100V” output terminal to the positive (+) connection of the speaker and “COM” output to the negative (-) connection of the speaker. Connect further speakers in parallel to the first speaker with all positive terminals and connected together and all negative terminals connected together as shown below.

Examples

LINE SYSTEM

A 100V line speaker system can comprise of many speakers connected together. The determining factor for how many speakers can be used on a single amplifier is the power rating. For most purposes, it is advised to connect as many speakers as needed with a combined wattage of no more than 90% of the amplifier’s output power rating. The terminals of a 100V speaker are connected to a transformer and in some cases, this transformer may be “tapped” for different power ratings. These tapings can be used to adjust the wattage (and output volume) of each speaker in the system to help achieve the ideal total power of the system for the amplifier.

SPEAKER TERMINALS
These terminals are offering a low voltage output of 8Ω. A 100V commercial output is also available.
Please note that one wire only should be connected to COM screw and one wire to the selected impedance or voltage.
ATTENTION : Multiple combinations cannot be done at the output level. Two different types of connections are provided. The low impedance section: 8Ω is designed for a small amount of speakers to be connected to your amplifier. The 100V section is especially designed for a multiple speaker distribution. When using the 100V output, speakers have to be equipped with a 100V transformer. The maximum amount of speakers to be placed on your distribution line is in relation to the power allocated to each speaker. The total wattage set on the secondary side of the transformers on your speaker line must not exceed the maximum RMS output power of the device. Failure to respect this may cause permanent damage to the amplifier.

OPERATION STEPS

When all connections to the amplifier are made, turn all rotary controls down and switch on the power and the power button LED will illuminate. Turn BASS and TREBLE controls to the 12 o’clock position (pointing straight up) and turn MASTER rotary control up part way for testing.
Ensure a signal is being fed to one of the line inputs and gradually increase the volume control for that channel until the output is heard through the speakers. Turn up the MASTER to the maximum required volume level and reduce the channel volume control if necessary.
Note: The initial test can be made using the built-in USB/SD audio player. The output of the amplifier is represented on the level meter LEDs and care should be taken that the Red “0” LED is only lit momentarily during use. Anything longer than a short flash of this LED may be indicating distortion or clipping of the output signal and the MASTER should be turned down.
If a microphone is connected to MIC1 input, make sure it is switched on and if it requires phantom power, make sure this feature is enabled. Gradually increase its volume control whilst speaking into the microphone until the required volume level is reached. The microphone should not be able to “hear” the speakers, which can cause feedback (squealing or howling noise). In addition to channel and MASTER volume controls, there are BASS and TREBLE EQ controls to adjust the tone of the overall output. At the 12 o’clock position, these controls are applying no effect to the signal (no boost or cut). Moving the BASS control clockwise boosts the low frequencies in the audio, whilst moving it anticlockwise will cut these low frequencies. Likewise, moving the TREBLE control clockwise boosts the high frequencies in the audio, whilst moving it anticlockwise will cut these high frequencies. Adjust these EQ controls to suit the type of audio signal or compensate for the room acoustics.

REPLACING THE FUSES

If a fuse is defective, replace the fuse with a fuse of the same type and value. Before replacing the fuse, unplug mains lead.
Procedure:

FUSES

Step 1: Open the fuse holder on the rear panel with a fitting screwdriver.
Step 2: Remove the old fuse from the fuse holder.
Step 3: Install the new fuse in the fuse holder.
Step 4: Replace the fuse holder in the housing.

After powering on, the buzzer inside will ring three times and then the output protection relay will be switched on (a click will be heard when this occurs), meaning the amplifier is ready

Rear Panel Overview:

Rear Panel Overview:

DC POWER INLET
The main DC power supply (24V) has to be applied to this connector. This is a standby power inlet to connect a 24V battery. A fuse holder with the main fuse is located on the top of the DC power inlet (for fuse replacement instructions, please see Replacing the fuses’).
AC POWER INLET
The main AC power supply (230~240V AC / 50~60 Hz) has to be applied to this AC power inlet. A fuse holder with the main fuse is located on the right of the AC power inlet (for fuse replacement instructions, please see ‘Replacing the fuses’).
FM ANTENNA
For using the FM radio function, pull out this antenna to ensure the best possible FM reception.
OUTPUT CONNECTIONS (RCA)
These connections can be used when expanding your system by adding a second amplifier. Connect LINE2 or LINE3 input of the second amplifier with this ‘OUT’ connection to do so.
UNBALANCED LINE INPUTS 2 & 3 (RCA)
RCA jack line inputs 2 & 3. Can be turned into a stereo line input by connecting right to red, left to white.
OUTPUT CONNECTIONS (TERMINAL BLOCK)
Output connections for both low impedance and constant voltage distributed audiosystems. The low impedance loudspeaker and 100V constant voltage output share a 4-PIN terminal block, left two can be used to connect low impedance speakers, the two on the right can be used to connect high impedance (100V constant voltage) speakers. Zone (1-4) outputs are represented by an 8-pin connector.
MIC3 / LINE1, MIC2 & MIC1 INPUTS
These channels use combination connectors, accepting both XLR and 6.3 mm jack plugs. Both inputs forms will mute all other channels when a signal is present on the connected microphones/inputs. Mic input 1 & 2 can be used for capacitive microphones. Phantom power switches enable 15 Volts phantom power when a capacitive microphone is connected. Switch 2 will feed phantom power to Mic input 1, while switch 1 feeds phantom power to Mic input 2.
EMERGENCY INPUT
The amplifier can be connected to any 100V constant voltage amplifier output with a DC 24V remote control used as the emergency input. When the DC 24V signals, the amplifier will switch to all connected speakers (constant voltage output) to send out the emergency signal.
TEL INPUT
The amplifier can be connected to any telecom system using the TEL input, allowing for announcements to be made from a handset. It is a line level input with priority. Unbalanced input connections should be made to the ‘CH’ (Hot or Signal) and ‘GND’ (Ground) terminals.
CHIME & FIRE INPUTS
Chime & Fire inputs allow for any external source such as call stations, a signal matrix- or fire alarm system to be connected to. These inputs have priority over other inputs.
BT ANTENNA
When connecting to- and using BT, make sure to adjust the BT antenna to a vertical position to ensure the best possible wireless signal.
