Stereo Audio Switching

Lattis LE-800A and LE-1600A are stereo audio switchers that accept line-level analog audio sources. The units provide each output zone with independent control of source-selection (routing) and volume levels -- essentially a multi-zone preamplifier. The Lattis LE-800AV is a combination stereo audio and composite video switcher.

These high-fidelity matrix switchers have adjustable bass, treble, balance, min, max, and mute levels for each zone. Volume may be controlled using commands for absolute, relative, or ramp-up/down-start/stop. Group commands allow source-selection and volume control of multiple zones together, in addition to independent zone control. Each zone also has adjustable initial turn-on volume levels and volume taper rates for smooth switching. Any zone may be set to Mono mode, with independent control over left and right volumes. Source-Leveling trims the input sources to the same level.

Any of our switchers may be daisy-chained together for up to 16 sources by 255 zones of audio/video distribution. With our stereo audio switchers, there is no need for a distribution amp to split sources -- a ribbon-cable option connects audio sources to multiple units, for minimal cabling.

Lattis Stereo Audio Switchers:

• High-Fidelity Stereo Audio
• 8x8 and 16x16 Source-by-Zone sizes
• Independent Source-Selection, Volume, Bass, Treble, Balance, Mono/Stereo and Mute for each zone
• Group Zones for concurrent routing/volume adjust, in addition to independent zone control
• Programmable initial turn-on volumes for each zone (or use previous levels)
• Source-Leveling for trimming input volumes to same level
• Audio daisy-chains using ribbon cables -- clean cabling and no distrubution amp


• Control via RS-232, Ethernet, and/or Infrared (IR)
• Daisy-chain any of our switchers together for up to 255 zones of audio/video
• Breakaway routing commands for audio-only, video-only, or audio/video together
• RS-232 and IR daisy-chain using modular cords -- control multiple switchers from a single port
• Powered by 12VDC, 1A adaptor

Distributing zoned audio throughout the home or building requires a stereo (2-channel) power amplifier for each zone. Since the Lattis Matrix Switcher provides Volume/Bass/Treble control internally, the zone amplifiers are generally fixed-gain (no volume control) power amps. Zone amplifiers are typically located near the Lattis system in the media center.

Our audio switchers allow flexibility and choice as to the type and quality of amp to suit each zone. Instead of using a separate stereo amp for each zone, a multi-channel amp may be used -- 2 channels (left and right) are needed for each zone (for example, an 8-channel amp will service 4 stereo zones).

Lattis Stereo Audio switchers units may be combined with any of our other switchers for various signal routing needs. When combined with our component- or composite-video switchers, RS-232/Ethernet control provides commands for switching audio/video sources together, or breakaway control for audio-only or video-only switching. In addition to RS-232 or Ethernet ascii commands, all Lattis switchers may be controlled using infrared commands from a Vaux remote control or IR-learning remote or keypad.
