The AV-1900 is a highly capable mixer-amplier packed with useful features to make it as easy as possible to operate. It

is designed for use in demanding applications like meeting spaces, small auditoriums, lecture theatres, school halls, and

small churches. It has professional audio features normally only found in much more expensive mixer amps.

1 x Line-level Pre-Output

Balanced Mic inputs with Phantom Power

RS-232 control

Bluetooth

For ease of connectivity it has a Bluetooth input. The device name and pin are xed and

cannot be changed. It can only pair with one device at a time. A device can be manually

unpaired by pressing the INPUT 3 dial. If you do not want Bluetooth active just set input 3 to

mic input with the switch on the rear.

Mixer Amp

This amp has four inputs, each of which can either be used for a microphone

or

a line-level

input. It is a true mixer amp, so it can bring together multiple sources and play them at the

same time.

Mic Pre-Amp Trim

The input gain for each mic input can be "trimmed" - adjusted on the rear panel. This allows the

installer to "turn up" less sensitive mics, and "turn down" hot inputs.

Four Microphone Inputs

All mic inputs are “balanced” to eliminate electro-magnetic noise induced on long cables. Input

1 uses a professional XLR connector - more convenient for rental and portable use, and the

other inputs use phoenix connectors - more suited to permanent installations.

Switchable Phantom Power

Each mic input has Phantom power which is a voltage required to make professional

condenser mics work. Phantom can be turned off on each input discretely.

RS-232

Designed for integration with a bigger system, it can be controlled by a control system such as

Techconnect Control via RS-232.

D-Class

An ecient Digital-class amplier chip dramatically reduces power consumption especially at

rest, and makes this amp super-small.

3 x Stereo Inputs

Three line-level stereo inputs accept input from a variety of sources such as computers (via

the headphone jack), tablets or phones. Inputs 1 and 2 use 2-phono (RCA) connectors. Input 4

is via a Minijack connector, and is duplicated on the front panel for adhoc access.

Line Output

A line-level pre-output on the rear bypasses the internal amplier. It would connect to a larger

amplier or powered loudspeakers. It is post-mix; volume adjustments made on the front

panel affects the output level.
