Owner’s Manual
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.

1. Inputs Level Controls 1 and 2 - Independently adjust the gain of the input 1 and 2 input signals. Turn clockwise to increase the signal level and counter-clockwise to decrease it. Note: The Input
Level Control knobs can be removed and replaced with a supplied security cover to prevent unauthorized adjustment.
2. Input Level Conrol 3 - Adjusts the gain of the input level of the input 3 stereo RCA inputs. Turn clockwise to increase the signal level and counter-clockwise to decrease it. Note: The Input Level Control knobs can be removed and replaced with a supplied security cover to prevent unauthorized adjustment.
3. Power LED - Illuminates Blue when 24VDC is present.
4. Input Peak LED - Illuminates Red when the input signal reaches 3dBV below when signal clipping
will occur. Occasional flashing is normal but if this indicator is continuously On, then reduce the input level using the input level control on the front panel.
5. Signal LED - Illuminates Green when the input signal strength reaches 25mV to verify a signal path.
Note: The LED will not illuminate if the input level is turned Off.
6. Limiter LED - Adjustment of the Limiter feature should be done after the input gain(s) have been
properly set. Each Input should be adjusted so the Input Peak LED flashes on signal peaks and then the Output Limiter control can be set so this LED flashes to indicate that the limiter circuit is active.
7. Bracket Retainer Points - Each TSD includes two mounting brackets for securing the TSD to a
cabinet or wall. Remove screws and align the bracket with the panel hole before firmly tightening the screws.

TSD Input/Output connections are removable for easy system wiring. The connector has a 3.5mm
pitch between pins.
1. DC Power Input - Each TSD that requires DC power comes with a 2 position connector for
an external 24VDC power supply (sold separately). Because of the low power consumption, a single external power supply may power more than one TSD. Refer to the current requirements in milliamps to match with the appropriate power supply. Note: It is acceptable to exceed the current
of the TSDs but NOT safe to use a power supply that is below the current requirement of the device.
2. Balanced Inputs 1 and 2 - Connects to balanced line or mic level sources. For gain or source input
type selection, refer to the “Dip Switch Function Identification” chart. Note: Unbalanced line inputs can be inserted with proper wire configuration by connecting the (G) and (-) terminals together.
3. Unbalanced Input 3 - Electronically sums unbalanced audio signals through stereo RCA
connectors. Level control is on the front panel . Input 3 can be muted via contact closure or an
audio signal on Input 1 for priority paging applications.
4. Input 3 Remote Mute - Connect a dry contact closure across these two terminals to mute Input 3 when the switch is closed. Dip Switch 7 must be in the On position.
5. Remote Level - For remote gain control, connect the Atlas Sound AAVC-10K (or equal) wall plate to this terminals. Set Dip Switch 8 to control a mixed signal or Input 3 signal only.
6. Balanced Line Output - Provides output for connection to balanced mic/ line level devices. Note: Unbalanced line level devices can be used with proper wire configuration by connecting the (G) and (-) terminals together.
7. Output Limiter Control - Sets peak output levels by increasing or decreasing the sensitivity. The Limiter LED on the front panel indicates when limiter is in use. Note: The control knob can be replaced with a supplied security cover to prevent unauthorized adjustment.
8. Vox Sense - Adjusts the sensitivity of the Mute circuit for priority pages. Set Dip Switch 8 to control a mixed signal or Input 3 signal only.
9. Cable Management Retainer Points - Use rear panel screws to secure included cable management retainers.

DIP Phantom Power applies power for condenser mic operation to SW
corresponding input terminal. Down position is On.
DIP SW # 3 - Input Mic or Line Select for input gain selection for Input 1. Up position is Line, down position is Microphone.
DIP SW # 4 - Low Cut Filter engages at 125Hz with a roll off rate of 12dB per octave. This filter operates either in the Line or Mic mode and is available on Input 1. Ideal for vocal microphones to reduce low frequency energy and to increase intelligibility. Down position is On.
DIP SW # 5 - Input Mic or Line Select for input gain selection for Input 2. Up position is Line, down position is Microphone.
DIP SW # 6 - Low Cut Filter engages at 125Hz with a roll off rate of 12dB per octave. This filter operates either in the Line or Mic mode and is available on Input 2. Ideal for vocal microphones to reduce low frequency energy and to increase intelligibility. Down position is On.
DIP SW # 7 - Input 3 Mute Receive will mute audio present at Input 3 when audio is present at Input 1. Down position is On.
DIP SW # 8 - Remote Level sets whether the remote volume control adjusts all inputs mixed or Input 3 only. Up position is all inputs, down position is Input 3 only.
Knob and Security Cover
All front panel level controls feature a removable knob that can be replaced with an included security
cover. Follow these steps to prevent potentiometer damage or unwanted changes.
1. Knob Installation - Turn the potentiometer shaft fully counter-clockwise. Align the knob indicator to the lowest setting on the panel and the potentiometer shaft slot. Carefully press the knob onto
the potentiometer shaft. Do not force or damage may occur to the potentiometer.
2. Security Cover Installation – Remove the knob from the panel and insert the cover. Do not force or
damage may occur to the potentiometer. Small pliers may be required to remove the knobs.
Mounting
There are three ways to securely mount this TSD:
1.Velcro™ - Each unit includes industrial grade Velcro™ with adhesive to adhere to any flat surface.
2. Brackets - Each unit includes two mounting brackets to secure to a cabinet or wall.
3. Rack Mount Panel - The optional TSD-RMK panel supports up to four TSDs in a 1RU space.
