Rear Panel Overview

AUDIBAX Zone 120BT fig 16 Rear panel description
The rear panel for amplifiers is identical and contains all connection and configuration controls (the model without “+BT” has no bluetooth antenna). Configuration controls include the settings which should be made once when setting up the system and doesn’t have to be changed by the user afterwards.

AC Power inlet
The main AC power supply (230~240VAC/50~60 Hz) has to be applied to this AC power inlet. The connection is made by an IEC C14 power connector A fuse holder with main fuse is located on the right of the AC power inlet. When replace the fuse make sure the replacement matches the specifications of the original fuse.

FM antenna
When using an FM radio, pull out the FM antenna to ensure a good FM reception.

Bluetooth antenna
When connecting the bluetooth adjust the bluetooth antenna to a vertical position to ensure a good wireless signals and longer distance.
Only the model with ‘+BT has a bluetooth antenna.

DC Power inlet
The main DC power supply (24V) has to be applied to the connector on the left of the AC power inlet. This is a standby power inlet to connect a24V battery. A fuse holder with main fuse is located on the top of the DC power inlet. When replace the fuse make sure the replacement matches the specifications of the original fuse.

Loudspeaker output connections (Terminal block connectors)
Output connections for both low impedance and constant voltage distributed audio systems are provided The low impedance loudspeaker and 100Vconstant voltage output share a 4-PIN terminal block, the two on the left are used to connect low impedance speakers the two on the right are used to connect high impedance (iust100V constant voltage) speakers. While different zone (1-4) outputs are provided on a8-pin terminal block connector More information about loudspeaker output connections is described in a further chapter of this instruction manual.

Link out connections (RCA jack connectors)
These connections can be used when expanding your system by adding a second amplifier in your system. Connect LINE2 or LINE3 input of the second amplifier with the OUT of the master amplifier in your setup.

Balanced line1/mic inputs12 &3(combination63mmjack&XLR)
Channels1, 2 & 3areimplemented using combination connectors accepting both XLR and 6.3 mm jack plugs. Both inputs 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 24Vots phantom power supply for 12V-48V capacitive microphone. Switch 2 will enable phantom power to Mic input 1while switch 1 enables phantom power to Mic input 2.

Unbalanced line inputs 2 & 3 (RCA jack)
Line inputs 2 and 3 are implemented using RCA jack connections it can be made a stereo line input red for right channel white for left channel. Chime &Fire inputs (Terminal block)
Chime &Fire inputs can be connected to any external source, such as call station, signal matrix, fire alarm system. These channels have priority over other inputs. Tel input (Terminal block)
The amplifier can be connected to any business telecom system using the tel input, allowing announcements to be made from any handset. It is a line level input with priority to be connected to the line output of the telecom system. Unalanced input connections should be made to the ‘CH’ (Hot or Signal) and GND (Ground) terminals. Emergency input (Terminal block)
The amplifier can be connected to any100Vconstantvoltage amplifier output of alarm system with DC 24V remote control using the emergency input. When the DC 24V is input the amplifier will switch the all connected speakers (just constant voltage output) to the alarm input.

Setting up the system

ATTENTION
Make sure the power of the device is turned OFF before any connections or wiring adjustments are made. Disregarding this rule can lead to permanent
damage of the equipment.

Connecting the loudspeakers
The loudspeakers should be connected to the euro terminal block connectors on the back panel of the device. First the decision should be made which kind of loudspeakers will be used between low impedance (4 Ohm) or constant voltage(100V/70V/) depending on the project requirements. It is only possible to use one (either constant voltage or low impedance) of both options at a time.
For operating using the low impedance (4 ohm) output any loudspeaker with a minimum impedance load of 4 ohms (that is 4 ohms or greater) can be used.

For operating using constant voltage (100V/70V/…) audio distribution systems, the positive output should be connected to the positive terminal of the loudspeakers, while the negative terminal of the speaker should be connected to the COM (ground) terminal of the amplifier.

Connecting the audio sources
The next step is making the signal input connections. Depending of the type connection and output level of the available audio sources they should be plugged into the matching channel/connection.
Before connecting, turn all the channel input and master volume controls on the front panel of the amplifier fully counter clockwise (to their minimum setting) and put the gain control trimmers on the rear panel in a central position. Then connect all the available sources to their corresponding channels and switch on the power of the amplifier and al the connected audio sources the green light around the power button will illuminate 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) that mean the amplifier is ready.
Apply a signal to the inputs as it will be used in normal operation circumstances and turn the channel input level control up about 50%Slowlyraise the master volume control till a certain level until the desired sound level is achieved Depending of the output level of the connected music sources the input gain might need adjustment Adjust these trimmers on the rear panel until the desired level is achieved.
For the best signal to noise ratio, the amplifier should run in normal circumstan-ces with the master level control near maximum position and the peak indicator (0 dB) of the VU meter on front should light occasionally (but not frequently during peak levels. If the signal is too loud or distorted use the input level controls to attenuate as necessary to achieve the desired speaker level.

Phantom power
MlC input 1&2contain the possibility for supplying 15Volts phantom power for powering condenser microphones. Enabling of the phantom power can be done by the switches located between MIC 1&2 connections. Switch 2 will enable phantom power to Mic input 1while switch 1 enables phantom power to Mic input 2.

To start playing music form MP3
Insert a USB storage device or SD/MMC memory card to the slots on front of the device. The MP3 player can play such as MP3WMAWAVFLAC. AAC audio formats When the media is inserted the device will detect automatically and will start playing You can select the playing tracks using the control buttons on front of the device. For switching to settings of another media source, press the M button on front (The variable audio output will switch automatically to this media source)

To start playing music via Bluetooth
Adjust the bluetooth antenna to a vertical position then press the M button on front to switch the operation mode to Bluetooth. Turn on the bluetooth on your device(phone computer, Ipad, mace or other music playback devices with bluetooth) and search for bluetooth device, you’ll find a device named” “,” ” and “ ” Bluetooth” in the list, select and connect it. Then you can play music on your device. pressing the to control the music track previous, next or pause.

Update the player’s firmware
New firmware that provides additional features or product improvements will be released as needed. You can download the type MVA of firmware from our website.
Format the USB storage device or SD card for upgrade firs. Insert a USB storage device or SD card with firmware on the front if the player detects firmware, it will automatically extinguish the LCD screen and start to upgrade the firmware, it will restart about 10 seconds later.

ATTENTION

Do not operate the amplifier or disconnect power cable during firmwave update Firmware update takes about10seconds
No files other than firmware in USB storage device or SD card.
