The AV-1900 is a highly capable mixer-amplier 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 ecient Digital-class amplier 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 amplier. It would connect to a larger
amplier or powered loudspeakers. It is post-mix; volume adjustments made on the front
panel affects the output level.
