The Multiuser Amplifier 219

Unlimited possiblities

Each room in the system needs its own Multiuser Amplifier that is connected to the Multiuser Server over a high-quality Ethernet network. The Multiuser Amplifier has an impressive 2 x 50 watt RMS making it powerful enough for most rooms. The outstanding output works excellently together with practically any speaker. Revox uses the integrated digital signal processor for its own speakers, in order to extract the best possible result from the combination of a Revox amplifier and Revox speakers.

Using a trigger input, an event can be started as a result of external influences. In the bathroom for example, a signal from a motion detector to indicate that someone is in the room can cause the light to be turned on automatically and the music to start playing.

Based on defined states of the Multiuser Amplifier, an additional trigger output can generate a control voltage. This could be used for example, to open up a screen for a home cinema system or to activate a TV lift. The amplifier also offers options for connecting a Multiuser wall-mounted unit, which as a concept, has proved itself for more than 30 years in the Revox world. Just a single press of a button and your favourite music starts to play, without having to search through your Smartphone for the right App and the right connection.

The optional Multiuser I/O Module

The Multiuser Amplifier has a module slot, in order to offer additional functions depending on the user requirements. The Multiuser I/O Module acts as an interface for many traditional audio products. Whether it is a television, a CD player or even Apple TV, you can connect almost all sources to a Multiuser Amplifier without any problem.

Each I/O Module has three audio inputs: one analogue input, one digital-coax and one digital-optical input. The sensitivity level of all three inputs is such that when an audio signal is detected, the amplifier switches automatically to the corresponding audio input. This results in a high level of operator comfort and offers the maximum flexibility when selecting which source is to be played. Additionally, the module has an audio output that can be set to match your requirements within the Multiuser Server. It can be configured as a traditional pre-amp output, as a Line Out or as an output for a subwoofer.

FAQ - Häufig gestellte Fragen

The Revox wall control provides only two users, however, several persons require access. Are there any approaches of Voxnet beyond the Apps?

On demand, the wall control units can be printed individually for a small additional charge. The flexibility of the Voxnet System allows the allocation of buttons with individual commands in the Voxnet Configurator. If required, the buttons can also distinguish between short and long keystrokes.



Is it possible to operate my Voxnet System with a classic infrared remote control?

Beside the Apps, Revox offers for Voxnet also a classic infrared concept - easy, across all systems and extremely reliable.

Based on RC5 infrared commands the Revox remote control can send RCM100 or M208 commands, also for third party devices, to the Voxnet System transmitting them to the required device.

How can I integrate an external product like a TV or Apple TV into the Voxnet System?

Revox offers the possibility to integrate the operation of external products into the Voxnet protocol via a Voxnet Proxy Service. Those proxies can be downloaded from a Revox database or created by a Voxnet installer.
