Figure 1: Front Panel Controls FRONT PANEL CONTROLS: 1. MIC/LINE LEVEL: A. PUSH-TO-TALK (P.T.T) 1 VOLUME / EQ: This knob lets you adjust the volume of the source at input 1 level, including for the P.T.T remote (PTT-100 – see diagram). Bass and treble controls let you adjust the sound output to suit your surroundings. B. REMOTE (R.M) 2 VOLUME /EQ: This knob (R.M 2) lets you adjust the level of input 2 and the A 4353 paging console. Bass and treble controls let you adjust the sound output to suit your surroundings. C. VOLUME 3 / EQ: This lets you adjust level for input 3, while the bass and treble controls let you adjust the sound output to suit your surroundings. IMPORTANT: If the priority function is activated and you supply a signal to mic or line input 1, then ALL other signals will be muted, including the auxiliary signal at inputs 4 & 5, paging ringer, and the modules in the front panel slot (CD Player / Radio Tuner). Note: It is preferred to keep the volume output level at or below ‘0’ on the LED indicator, while setting the MASTER volume to the two o’clock position.
5. TELEPHONE: A. TEL NIGHT RINGER: Allows you to hear the telephone ring via the speaker. Push the button in to activate the feature. Turn ringer volume anticlockwise to decrease the ringer volume. (-20dB attenuation from maximum volume.) B. PAGING: You can adjust the broadcasting of the pager using the knob under ‘TEL’. IMPORTANT: In case paging is activated, priority will stop all signals. Set the jumper shunt MS1 on the front PCB to SLAVE. If priority is not activated against mic input 1, 2 or 3 (see DIP switch on rear panel) all mic signals will be muted. 6. SIREN: This is for emergency situations. Two sounds are offered depending on which button is pressed: Alert siren curve (repeat) Alert siren flat (continuously). The knob controls the volume level. 7. MASTER: All signal volumes from Mics, Aux, slot devices etc are governed finally by the MASTER volume control knob. The two LED lights signal problems with the device when lit.
2. LINE LEVEL: This volume control lets you adjust the input of the line level. Bass and treble controls let you adjust the sound output to suit your surroundings. 3. PACK EQUALIZER: BASS and TREBLE control for pack series. 4. CHIME: Pushing the CHIME button once will activate the two/four tone chime; this can also adjust the signal level. This is for pre-signal or an alert signal. To set the chime tone an internal jumper may be adjusted. It is labeled MS1 on the front PCB of the amplifier.

Figure 2: Rear Panel Controls REAR PANEL CONTROLS: 1. MIC PRIORITY SWITCH: These are the priority-setting switches for microphone inputs 1, 2 and 3. To change priority ranking from No.3 to No.2 turn switch lever to the right. 2. P.T.T REMOTE JACK (DIN 7 PIN): Currently unused.This feature is currently unsupported. 3. MIC/LINE INPUT: Inputs 1-3 allow you to connect balanced microphone (XLR) or line (TRS) sound sources. The gain knob varies the input signal from -10dB to -50dB, depending on the type of source plugged in. If the main output LED level clip indicator flashes red, adjust the gain control to a level so that clipping ceases. The XLR and 6.35mm phone combo socket suits mic or line input, and can supply phantom power to a condenser mic connected via the XLR connection. Pin 1 on the XLR and the sleeve on the phone jack are grounded (see block diagram). IMPORTANT: Turn the volume control on the front panel anticlockwise to decrease the level when you are using phantom power, so as to avoid damaging the speakers. 4. LINE IN 4-5: Inputs 4 and 5 are used for the connection of line-level equipment such as a cassette deck or a CD-player. The stereo signal of the connected source is internally converted into a mono signal. 5. RECORDING: Recording output has been installed using two L-R unbalanced RCA jacks. The stereo signal of the connected sound sources is internally converted into a mono signal. All signals can be recorded but recording output level (0 dB gain) can not be adjusted by master volume, since it is wired to be pre-fader. (See Block diagram). This output could be connected to a logger recorder of some type. 6. AMP IN / PRE OUT: A. AMP IN: This unbalanced input is for a direct signal input from external equipment (+4dB level). It is controlled by the master volume control on the front panel. A signal processor receiving a signal from the pre-out can ‘return’ the processed signal to the amp input. B. PRE OUT: This 6.35mm jack is for connecting an unbalanced line level output signals to and external amplifier or a signal processor such as an equalizer. The signal is PRE-fader for the Master Volume. 4
IMPORTANT NOTE: The output impedance should be 600Ω for pre-amp operation. 7. SPEAKER ZONES & ATT. OUTPUT: Pushing a speaker zone selector button (front panel no.8) will assign the master volume output signal to the selected zone. If the all call button is pressed, the zone selector of paging console (A 4353) are activated, and the selected zone output is reset to 100V/70V output. 8. LOW/HIGH IMPEDANCE OUTPUT: Direct out jack has been designed for low impedance output (4 Ω/100V) in conjunction with attenuator control. 9. TELEPHONE: NIGHT RINGER: Connect night ringer terminal to telephone line. You can hear the telephone ring via speakers in other zones. PAGING IN: These terminals are for connection to a telephone system for paging. Use an Austel approved line isolation unit with this input. 10. MESSAGE FIRST PRIORITY: Currently unused.This feature is currently unsupported. 11. DC POWER: This terminal is for connecting the 24V battery for battery operation. WARNING Ensure the correct battery polarity to prevent damage to the amplifier. The battery connection cable has to be 3.0mm in diameter and should not be any longer than 7m. POWER REMOTE: you can turn on/off amplifier by remote by wiring up these terminals 12. AC POWER INPUT OPTIONAL ACCESSORIES: 13. ANTENNA TERMINAL (OPTION): (Supplied with A 4344A or A 4346 modules) FM: You can connect 75 ohm coaxial cable or 300 ohm feeder cable. AM: Connect it to an AM antenna. GND: Earth terminal required for AM reception. 14. PAGING CONSOLE CONTROL MODULE (A 4352): LINK/INPUT RJ45: Connects to remote zone paging consoles (A 4353). Power, data and control signals are all transmitted along a single length of Cat5e UTP cable. The combined total length of cable pairs from the amplifier to the last A 4353 pag-

The combined total length of cable pairs from the amplifier to the last A 4353 paging console is 1000m. See Figure 3. 8. AUX INPUT: AUX input is for a local audio source or pre-recorded message. 9. AUDIO OUT GAIN: This knob controls the audio output volume.
1. POWER: Turn on the power, LED indicator lights. 2. SEND: LED flashes to show that data is being sent to amplifier. 3. BUSY: BUSY means under operation of TALK. If slave has been selected on the rear panel, this LED will no longer illuminate. 4. TALK: Pressing this switch will let you talk via the built in paging microphone, preceded by the programmed chime signal. 5. ZONES SELECTOR: Pressing one of the zone buttons (1 to 6) sends the signal to the desired zone. The attenuation on the main amplifier is reset and the zone output power is converted to HI impedance. The corresponding LED indicator lights up. Select your preferred speaker zone before pushing the talk button, otherwise none of the other switches will operate. See Figure 4. 6. SLAVE/PRIORITY: When operating two or more paging consoles simultaneously in a daisy chain connection, one of the paging consoles can be given priority while the other is set to slave. In the event that the paging console is set to slave, and the talk button is pressed, it will operate only after the master paging console has finished operating. 5
