Logitek’s Audio Engine is a full-featured TDM (Time Division Multiplexing) audio router. It efficiently manages all the audio in your facility: analogue and/or digital I/O, balanced or unbalanced, intercoms, mix-minus feeds and more.

Connection to Logitek consoles (control surfaces), router controllers and other devices is simple. Any Logitek console works with the Audio Engine, and up to eight devices, including up to three consoles, may be attached to a single Audio Engine.

The functionality of patch bays, audio switchers, interface amplifiers, sample rate converters, D/A and A/D converters is provided in even the most basic Audio Engine configuration. Audio processing functions including profanity delays, dynamics and EQ are also possible, as is networking of multiple Audio Engines to provide more I/O and console connection capacity.

The Audio Engine is designed to hold two load sharing, universal voltage audio supplies, a communications controller card, up to two DSP cards, and up to

eight I/O cards which can be a combination of analogue and digital cards. All cards are hot-swappable for easy service.

A minimum Audio Engine configuration consists of the frame, one power supply, one Communications Controller card, one DSP card and at least one audio card. A second power supply can be stacked in the frame for redundancy. A fully loaded frame will accommodate two DSP cards and up to eight audio cards (seven if a networking card is used).

DSP cards utilize the powerful processing technology of the Analog Devices SHARC™ DSP. These DSPs enable “real-time” audio mixing, processing and distribution with very low latency from all inputs to all outputs. Two DSP cards are available, the LoneSHARC and the multi-DSP SHARC Attack. The LoneSHARC will provide basic functions for the Audio Engine and one control surface. For more advanced capabilities such as dynamics, delays or multiple control surfaces, at least one SHARC Attack card is required.

Audio Card options include:

IO24A - This is the analogue audio I/O card providing

12 single channel inputs and 12 single outputs. Any pair of input or output channels can be linked for stereo operation. Signals are line level, with independent gain and output trim controls. Analog signals are converted to and from the digital domain using 24 bit converters for maximum audio quality.

IO8D - This is the digital audio I/O card providing

8 digital inputs and outputs. Each input has an on board sample rate converter, and can accept either AES or S/PDIF digital formats.

When both analogue and digital I/O cards are used, the Audio Engine can route an analogue source to a digital destination and vice versa. This gives you the ultimate flexibility in determining your audio distribution requirements.

If you need to link multiple Audio Engines, order the NET-A card for each Engine that allows you to link as many as 32 Audio Engines together for sharing of up to 500 audio sources.

This gives you the power and control of a large house router, in smaller easy to manage units. Audio on one engine can be mixed with audio on any other engine, and all can be routed out any combination of outputs.
