The VX-1100 Modular Amplifier Range

The VX-1100 Range is based on a series of Eurocard modules each capable of accepting a range of inputs, processing stages and outputs, the result being a comprehensive list of broadcast audio functions. We use these modules to build our own system products such as PPM audio monitors and, being Eurocards, you can use the modules to build products of your own. Here's a list of the basic functions, which can be assembled in any combination, followed by some examples of constructed modules.
 

We have assembled a group of audio converters based on the VX-1100 modules, providing popular functions in a 1U rackframe. Here are some examples:

The VX-2035 is a versatile dual-channel buffer amplifier offering convenient 4-wire interface to telecommunications equipment. It provides a low-cost, portable solution for talkback and other communications using PSTN, ISDN and cellular services, and can also serve as a stand-alone mic, headphone or buffer amplifier. Used in conjunction with a standard PSTN or ISDN telephone it offers similar capabilities to a hybrid, and is equipped with a handset socket and switching to select handset or 4-wire operation.

The VX-2086 is a dual channel balanced analogue audio distribution amplifier offering excellent performance exceeding current broadcast specifications. Eurocard-based, it has an on-board rectified and regulated power supply operating from low voltage AC or DC, making it ideal for incorporation in many existing rackframes.

There are two input buffers per card, and four output drivers each with 6 resistively distributed outputs. any output driver may be linked to either input, which means that the VX-2086 can be used as a 12 output dual channel (stereo) DA, a 24 output single channel DA, or as a dual channel DA with 18 outputs on one channel and 6 on the other. The signal path is balanced throughout, with properly filtered inputs and outputs. Jumpers provide phase reversal and a choice of earthing options.

The VX-2088 Eurocard module supports 8 channels of balanced audio input which are output as unbalanced audio, and 8 channels of unbalanced input which is electronically balanced and output. One or other half of the card can be used as a simple balancing or unbalancing amplifier, but a complete card is a cost-effective way of unbalancing audio prior to input to a switcher (such as the VX-8500 Series) and re-balancing it after switching, saving an entire switching level.
