Description
The AtlasIED 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 amplifiers 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 amplifier (or other device) input sensitivity. The TSD-TXHL works perfectly in conjunction
with AtlasIED’s CP and PA series.
The TSD-TXHL is part of a full line of AtlasIED 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, 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.

Cable Management
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. Small pliers may
be required to remove the knobs. Align the security cover to the level control panel hole. Push the
cover into the hole until it snaps into place. Do not force or damage may occur to the potentiometer.

2. Multi Mount Plate - Each TSD includes a versatile multi-position mounting plate. This plate
allows the TSD to be mounted to any surface; but is ideal for use with rear rack rails or side rack
hat channels. Use the included M3 x 4mm screws to install the plate on the TSD. Note: Only use
the included M3 x 4mm screws as other screws may be too long and will cause internal damage
to the TSD. The multi-position mounting plate is a new addition being included with TSDs. If the
TSD being used did not include the mounting plate, contact AtlasIED customer service at
