AV-1700 2 x 30w Digital Amplifier & SP-1700 Pair 2-Way Wall Loudspeakers
AV-1700:
The Techaudio AV-1700 is compact, flexible, easy to use and is extremely efficient. Use as a standalone mixer and amp, or as a mixer which outputs to a bigger amp or powered loudspeakers.
4 x Stereo Inputs
4 stereo inputs accept input from a variety of sources such as computers (via the headphone jack), tablets or phones. 3 of the inputs are via 2-phono (RCA) connectors on the rear panel. Input 4 is via a 3.5mm minijack connector, and is duplicated on the front and rear panels for easy access.
Line Output
A line-level pre-output on the rear panel bypasses the internal amplifier. It would connect to a larger amplifier or powered loudspeakers. It is post-mix, which means any volume adjustment made on the AV-1700 affects the output level.
Microphone Input
It uses a professional XLR connector and the input is balanced to eliminate electro-magnetic noise induced on long cables. The microphone input has “Phantom Power” – a voltage which is required by condenser-type microphones such as lectern microphones.
Remote Control
The IR remote control gives the user bass and treble adjustment and direct input selection. The AV-1700 can be controlled by a control device such as Techconnect Control via IR or RS-232.
Simple Interface
The clear simple interface offers the user just two dials.
Auto-Standby
If the amplifier senses no input it will automatically go into standby mode. As soon as you press play on your source device it will automatically switch on again.
Mounting Options
Optional mounting hardware is available which allows attachment to a wall, projector ceiling pole, or rack.
SP-1700:
Vision’s SP-1700 wall mounted loudspeakers are easier to install than any other speaker in its class, with superb sound quality and a robust chassis. They are powerful, professional, and acoustically optimised for Vision’s range of digital amplifiers.
Lower Bass Response
A structurally rigid MDF chassis and a specially tuned bass reflex port have extended the bass response down, resulting in more natural music reproduction.
Rugged Grille
Refreshed industrial design makes the SP-1700 attractive and robust. The thick metal grille protects the drivers from physical interference.
Tough Finish
The finish withstands the rigors of the professional use.
AV Applications
The SP-1700 are designed for corporate meeting rooms and teaching environments. These presentation environments demand a wide dispersion so everyone in the audience can hear clearly, so ferro-fluid cooled dome tweeters are used.
4″ Woofer
Quality components are standard in any Vision product. The SP-1700 is no exception with powerful drivers which can be pushed hard.
Close-fit bracket
The adjustable brackets allows the loudspeakers to tilt vertically, ensuring the sound is projected in the right direction. Loosen the screws to slide the chassis out from the wall allowing easy access to the cable termination points.
