Line Level Adapter

The TA1 Line Level Adapter is designed for connecting an

Audio/Video Teleconferencing Hybrid to Lectrosonics auto-

matic mixers. It can also be used to add a line level audio

input or interconnect a tape recorder to the mixer.

With the AUTO MIX switch in the “ON” position, the video

codec (or other audio source) will participate in the auto-

matic mixing algorithm applied by the mixer.

cases, this will eliminate the need for acoustic echo cancel-

lation within the hybrid in teleconferencing applications that

use a sound system with multiple microphones and loud-

speakers. In addition, an incoming signal from the far end of

the telephone or ISDN line will attenuate the gain on the

local microphones to eliminate acoustical coupling between

microphones and loudspeakers that could cause a feed-

back loop.

The TA1 picks up a “mix minus” output from the mixer

expansion bus. This output contains all inputs connected to

the mixer, but does not include the signal connected to the

INPUT jack on the TA1.This arrangement provides simulta-

neous send/receive for a teleconferencing hybrid and

prevents the output of a tape recorder in the “record” mode

from getting back to the input.

When used with the AM8 or AM16 mixer, TH3 telephone

hybrid, and a video codec, 3-site bridging can be accom-

plished without the need for any other routing device.

The TA1 comes with two 24” eight pin expansion cables,

part # 21592.
