Vision TC3-AMP+SP-1800

TC3-AMP 50w Digital Amplifier


·         Extremely small 2 x 25 w (RMS) at 8 ohms Digital Amp

·         2 x Stereo inputs (Input 1 duplicated on front and rear)

·         IR Remote control included

By using latest low-impedance digital amplifier chip technology the new Techconnect Amp module outputs a massive 2 x 25 watts RMS (at 8 ohms) but fits into the space of a Techconnect module.

Front Panel Input
Two Inputs are wired into the rear with removable phoenix connectors, but Input 1 is also duplicated on the front panel with a minijack socket for convenience. This “half-normalled” input disconnects the rear terminal while in use.

D-Class Amplifier
Digital amplifiers use no power unless they are amplifying program, so even on at full volume; unless it is receiving input it is effectively off. Digital amplifiers also have the advantage of running cold so a bulky heatsink is not necessary

Power Four Speakers
Don’t let size deceive you: the Techconnect  Amp can drive into a 4 ohm load allowing you to power up to four 8 ohm speakers (or two 4 ohm speakers).

Preset Memory
By default when power is activated the Techconnect Amp turns on and resumes the most recent settings. For hospitality applications it can be set to return to a preset input and level whenever it is powered on – for example in hotel guest rooms.

Tactile Dial
A simple clear control interface makes the product easy to use long press on the dial to power on and off. Short press to change input.

Remote Control
A remote control is included and IR receivers are positioned on the front and rear for integration with a control system such as the Techconnect Control. Note: there is no tone control with this amplifier. Vision’s spare remote controls have tone buttons but they do not work with this product.

Easy to Install and Uninstall
A robust module that is easy to install or remove and disconnect from the front. Removable phoenix connectors allow non-technical end users to uninstall it very easily if required.

Cables Included
Speaker cable is included plus short input cables are included for connection to the rear of adjacent input modules on the Techconnect.

Ideal when you don’t have furniture to sit an amplifier on, and because it is mounted to the wall it is much less obvious as a target for theft.

Close at Hand
Can be positioned anywhere in the room making it perfect for training rooms, boardrooms, and classrooms.

Integrated Techconnect Family
Included is a single-gang backbox and surround, or alternatively you can mount it in a double-gang surround with other Techconnect modules.

SP-1800 Pair 3-Way Wall Loudspeakers

5.25″ Woofer 50w loudspeakers
Wall brackets included with 60º range of tilt adjustment
White, sold in pairs

Vision’s SP-1800 professional wall mounted loudspeakers are super-easy to install, look beautiful, and produce rich and powerful sound.

They are 240mm tall and use a 5.25 inch woofer – the most popular size for classroom, meeting room, and boardroom applications.

These loudspeakers use three drivers; a woofer, a squawker, and a tweeter. Asking a driver to produce a wide range of frequencies is always a compromise, so dividing the sonic range into three means each driver has a narrower range of frequencies to produce, resulting in less distortion and clearer sound.

Bass Reflex
A bass reflex port allows greater excursion of the woofer, allowing the woofer to produce lower frequencies, and the phase-delayed movement of air from behind the woofer to the front reinforces the bass even more.

Rugged Grille
A metal grille protects the drivers from physical interference.

Tough Finish
Constructed with tough ABS plastic, the finish withstands the rigors of the professional use.

Pro AV Applications
In small to medium presentation environments a wide dispersion is generally more important than microphone feedback management, so no horns are used.

Horizontal C bracket
The adjustable brackets allow the installer to easily angle up 30º or down 30º. Or leave the brackets off and use as shelf speakers.

Note: these are passive loudspeakers – there is no amplifier built in – so they need to be used with an external amplifier.
