Vision AV-1900 50W Amplifier and Pair of CS-1900 Ceiling Speakers Kit

CS-1900 FEATURES:
The simple attenuation switch on the front allows the user to fine-tune the EQ for the environment.
 
Titanium dome
The large tweeter is made from premium material and pivots to help installers setup the soundscape. Titanium ensures long, stable performance and reduces distortion.
 
Magnetic grill
The grill clips into place magnetically once the speakers are secured.
 
Invisible
The grill extends all the way to the edge of the speaker resulting in virtually no visible edge. This ultra-thin grille allows the technology to visually disappear.
 
Crossover
Gold plated terminals and a quality crossover circuit is included which splits the work between the woofer and tweeter.
 
High sensitivity
Ceiling speakers often lack the power of wall speakers, but these have a higher sensitivity of 90dB to cut through high-noise presentation environments.
 
AV-1900 FEATURES:
For ease of connectivity it has a Bluetooth input. The device name and pin are fixed and cannot be changed. It can only pair with one device at a time.
 

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 discreetly.
 
RS-232
Designed for integration with a bigger system, it can be controlled by a control system such as Techconnect Control via RS-232.
 
Line output
A line-level pre-output on the rear bypasses the internal amplifier. It would connect to a larger amplifier or powered loudspeakers. It is post-mix; volume adjustments made on the front panel affects the output level.
 
Auto-standby
If the amplifier senses no input it will automatically go into standby mode. When it senses input it will reactivate. Auto-standby can be disabled via RS-232.
