Description
The versatile Atlas Sound TSD-MIX31RL 3x1 mic/line mixer is ideal for applications where paging,
public address, and BGM music are required. Use alone or in conjunction with amplifiers in meeting
rooms, stadiums, gymnasiums, and other applications requiring versatile, multi source mix control.
The unit includes two mic/balanced line inputs via removable Phoenix style connectors and a stereo
summing dual RCA input. Switchable phantom power is provided for both mic inputs to facilitate
condenser microphones. The high quality, low noise internal mic preamps ensure clarity and quiet
operation without unwanted coloration. A 12dB/octave high pass filter @ 125Hz also is available on
each input to minimize bass rumble and low frequency feedback.
Priority paging can be accomplished via contact closure or VOX trigger on Input 1 (mutes input 3 only).
Remote level control feature allows use of the Atlas Sound AAVC-10K (or equivalent) decorative wall
plate control for convenient remote adjustment of either the entire mix bus or input 3 only (typical BGM
input). A variable output limiter provides system protection by reducing clipping and distortion - which
is especially useful when mixing multiple mics and/or line sources with varying volumes.
The TSD-MIX41 is part of a full line of Atlas Sound Time Saving Devices. These compact
(1.5" x 4" x 2.75") units are designed to solve some of the common audio system problems in the
easiest and in the most efficient and cost-effective way. All models are made from high quality
components and include removable individual I/O connectors for quick and precise wiring, separate
ground terminals for all I/Os assuring secured connections, and removable level controls that can be
replaced with tamper-proof security covers. The TSDs are highly efficient and meet Energy Star™
standards as one 24V DC power supply (available separately) can power multiple Time Saving Devices.
