Introduction
Model WTSD-MIX31 is a 3x1 Mic / Line / Aux / Bluetooth analog mixer that features a
balanced microphone / line input and an auxiliary 3.5mm and Bluetooth summed input
with a balanced line output. The WTSD-MIX31 utilizes commercial grade Bluetooth
technology featuring ultra low noise levels, long range connectivity, no auto connect and
quick disconnect bump feature. Selection between mic or line level for the XLR input is
done via front panel switch. The high gain mic inputs incorporate user enabled Phantom
Power for condenser microphones and a 125Hz low cut filter to eliminate unwanted low
frequency interferences. A local mute button mutes output to the bus and a system
priority button can mute building wide BGM systems to isolate the room. An adjustable
VOX feature allows for AUX input background audio to be muted when announcing is
present. The AUX input is a stereo 3.5mm jack and is electronically summed to achieve
the best audio performance. Separate level controls for each input provide control for the
audio mix needed.
A basic WTSD system consists of four elements; a WTSD mixer, Cat5/6 cable, inline 24V
DC power supply and an end point break out board / hub. All four are included with the
purchase of a WTSD mixer except for the Cat5/6 cable. A 2-gang box is all that is needed
to complete an installation. There are two versions of the WTSD end points offered. The
WTSD-PWBOB comes with each unit and features a balanced audio output with signal,
mute, system priority and power LEDs and 12V DC logic output for remote system muting
or power sequencing. The WTSD-PWHUB is sold separately and features level control
at the system head end, input limiting, isolated relay outputs to trigger system priority
muting or system power activation, and an emergency mute port. The WTSD features an
energy saving auto sleep function that can shut off the audio system when not in use
after approximately 1 hour. As soon as the WTSD mixer senses an audio signal, the WTSD
sends a command down the bus to wake the system up.
The WTSD-MIX31 analog audio BUS can easily be converted to an Audinate Dante®digital
signal by interfacing with the optional AtlasIED TSD-DAC2i converter. The WTSDs are
uniquely designed to fit into most 2-gang electrical boxes and utilize industry standard
Cat5/6 cable for power, control, and audio. The WTSDs deliver high quality audio hundreds
of feet by the use of a low noise / high gain preamp design and balanced audio bus. The
proprietary low voltage bus is designed so that up to 3 WTSD mixers can be daisy chained
on the same bus cable run while allowing for independent mixer operation. Each WTSD
incorporates separate level controls for each input, a local mute, system priority override
and an auto sleep function.
The optional WTSD-COVER stainless steel weather resistant locking security cover with
gaskets is available for tamper proof indoor or outdoor applications. The PCBs are weather
treated to reduce corrosion in damp environments. With the PCB treatment and the
WTSD-COVER accessory, the installation will have protection against the environment and
tamper protection for years of continuous operation.
