Description

The AtlasIED TSD-DA28 2x8 distribution amplier is designed to provide clean, isolated signal
distribution locally or to remote locations. The unit allows two independent balanced line level source
inputs to be distributed to eight isolated variable outputs making it a perfect solution for applications
including convention centers, houses of worship, restaurants/sports bars and industrial facilities.
Isolation between outputs prevents crosstalk, removes miss matched input impedance concerns
and allows for adjustable levels on each connected device. All I/O is via Phoenix style connectors for
installation convenience and inputs may be easily paralleled for 1 in / 8 out conguration.

The TSD-DA28 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 efcient 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 efcient and meet Energy Star™ standards as one
24V DC power supply (available separately) can power multiple Atlas Time Saving Devices.

Front Panel Description

1. Input Level Controls - Adjust the gain of the source audio signal that is applied to the DA28
circuitry. Turn clockwise to increase the signal level and counter-clockwise to decrease it.
Note: The Input Level Control knob can be removed and replaced with a supplied security cover to
prevent unauthorized adjustment.

2. Output Level Controls - Adjust the level of each of the eight outputs using these individual controls.
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. 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 ashing 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.

Rear Panel Description

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 TSD’s low power consumption,
a single external power supply may power more than one TSD. Please refer to the specications
on current requirements in milliamps to match with the appropriate power supply. Note: It is
acceptable to exceed the current requirements of the TSDs but NOT safe to use a power supply
that is below the current requirement of the device.

2. Balanced Line Input - Connects to a balanced line level source. Your connection must be mated
properly to the input connector or signal loss and/or noise may occur. Note: Unbalanced line level
inputs can be inserted with proper wire conguration by connecting the (G) and (-) terminals
together.

3. Balanced Line Output - Connections to provide output when an input signal is present for
connection to balanced line level devices. Your output connections must be connected properly to
the connectors or loss and/or noise may be introduced into the signal. Note: Unbalanced line level
devices can be used with proper wire conguration by connecting the (G) and (-) terminals
together.

4. 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.
