SAFETY INSTRUCTIONS

Please read these safety instructions carefully.

1. Keep this User Manual for future reference.

2. Power connectors should remain accessible for disconnection and be located

where no-one can step on or trip over them. Disconnect the equipment from the

alternating current (AC) output before cleaning.

3. The device must not be exposed to water or drips and no liquid-filled objects should

be placed on top of it. Do not use liquid or powdered detergent for cleaning. Do not

expose the device to moisture or damp areas.

4. No naked flame sources, such as lighted candles, should be placed on top of the

device.

5. The device must be installed on a safe surface. If the device is not placed on a

safe surface, it could fall and become damaged.

6. Never open the device. For safety reasons, the device should only be opened by

qualified personnel.

7. Pay attention to the connection polarity when operating equipment with a direct

current (DC) power supply. Reverse polarity connection may damage the

equipment or power supply.

8. If any of the following situations occurs, please get technical personnel to check

the device:

a) The power cord or plug is damaged.

b) Liquid has penetrated the inside of the device.

c) The device has been exposed to moisture.

1. TECHNICAL DESCRIPTION

The A-1 is an advanced paging microphone for professional PA installations.

The microphone can be controlled by logical digital signals, or RS-485 communications protocol

(optional).

The sound processor has been adapted to achieve high quality results, in terms of quality,

distortion, sensitivity, broadband and S/N ratio. That is why the A-1 includes a high quality

dynamic amplifier.

The A-1 has different modes of configuration, in order to be easily integrated in any type of

installation. Additionally, it features pre-amp to provide a balanced output and preserve the

audio quality over long distances.

As an option, it is possible to configure a chime tone before and after a paging.

3. FUNCTIONING DESCRIPTION

The A1 microphone functions as an “all-call”, press to talk, single button microphone. It features

LED indicators to signal the state of the line/zone where the page will be broadcasted.

Functioning modes:

Depending on the mode that has been selected internally, the microphone can perform different

actions.

i. PTT/LATCH Mode - When the microphone selector is set to OFF, the microphone will

work in PUSH TO TALK (PTT) mode and the button should be pressed in order to make

a page. When set to ON, the first push of the button will fix the microphone to the floor

“granted” to the user to begin. A second push, will then end the transmission.

ii. 0V/5V Mode - Using the operation selector, it is possible to configure the TTL output line

signal, to indicate the use of the audio line in the system. 0V is low level signal and 5V is

high level signal.

iii.

Chime ON/OFF - This position indicates if the chime tone is ON or OFF.

iv. TTL/RS-485 Mode – The default functioning mode is TTL. The A1 can also use the RS-

485 protocol to communicate with LDA compatible units. In that case, this option should

be active and the “jumpers” situated in the correct position. This will always be activated

by the technical team because an incorrect configuration could result in the A1 failing to

function correctly.

BUSY=LED Mode - This configures the operating mode when the line is busy. In the

OFF position, the microphone will not send audio or operation signals while the “BUSY

LINE” signal is active. In the ON position, the microphone will only operate over the

corresponding light indicator, sending signals of petition and audio. This mode normally

requires a microphone signal process.
