Description
The Atlas Sound TSD-TXHL is a high to low level converter designed to interface with
4Ω/25V/70V/100V distributed speaker lines. An unbalanced line level output is provided to drive
remote ampliers or other devices.
The TSD-TXHL allows easy expansion of zones without the need for dedicated wiring to remote
locations. The high to low-level converter features an isolated transformer, which will not add
measurable load to the speaker line. An output level control allows for trim adjustment to best match
the remote amplier (or other device) input sensitivity. The TSD-TXHL works perfectly in conjunction
with Atlas Sound’s CP and PA series.
The TSD-TXHL 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 ecient and cost-eective way. All models are made from high quality
components and include removable individual I/O connectors for quick, precise wiring and separate
ground terminals for all I/Os assuring secured connections.

Rear Panel Description
TSD Input/Output connections are removable for easy system wiring. The connector has a 3.5mm
pitch between pins.
1. Speaker Level Input - Connect the loudspeaker line to the (G) and (+) terminals. The loudspeaker
line can be 4/8 ohm system or 25/70/100V signal levels.
2. Output Level Control - Adjust the signal level of the unbalanced line output. Turn clockwise to
increase the signal level and counter-clockwise to decrease it. Note: The output level control
knobs can be removed and replaced with supplied security covers to prevent unauthorized
adjustment.
3. Input Gain Adjustment Switch - Set this switch to match the signal level present on the
loudspeaker line. Use the 4 - 25V ohm position for 4/8 ohm and 25V systems, 70V or 100V for 70V
and 100V loudspeaker systems, respectively.
4. Unbalanced Line Output - Provides an unbalanced line output when an speaker level input signal
is present. Output is variable with adjustments made with the Output Level Control. Note the
polarity of the connector, reversing the polarity can cause sound quality issues.
5. Cable Management Retainer Points - Each TSD includes two cable retainer straps for securing
the included cable management retainers. Remove one of the rear panel screws, align the
 panelholewitharetainerandrmlytightenthescrews.

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 backing 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 rack mount panel supports up to four TSDs in a
1RU space.
