Overview

Our take on the Atlas TSD-ZDC

Atlas has been doing commercial audio installations long enough that they've created devices to solve problems you didn't even know existed. The TSD-ZDC is a versatile signal adapter that can be used in a number of ways. For instance, you can sum a line-level stereo source for playback on a mono commercial audio system, or divide a single mic-level signal into three different outputs, allwithout causing impedance problems. It's the sort of handy little gadget that'll make you wonder how you ever got along without it.

Features

Overview: The Atlas Sound TSD-ZDC is an ultra-compact 4 x 4 Impedance Divider/Combiner, designed for passively summing or splitting microphone or line level signals. The TSD-ZDC requires no separate power supply.

Time Saving Devices (TSDs): The TSD-ZDC is part of Atlas Sound's Time Saving Devices, or TSDs, for short. TSDs utilize high quality internal components, and were designed to provide efficient and cost-effective solutions to "real world" installation problems. Atlas Sound's TSD line includes mixers, amplifiers, preamps, distribution, and control devices. All of the TSDs are housed in a compact 4" x 1.5" x 2.5" (or deeper) black aluminum chassis.

Audio Applications: The TSD-ZDC solves some common problems found in audio distribution. When integrating a stereo signal with a mono, single channel background music/paging system, it was necessary to either choose only one channel from the source or short the two channels together. With the TSD-ZDC, you can passively sum the two channels without shorting them. Other audio applications include:

  • Combine up to 3 microphones to one output
  • Divide a single microphone to 3 mic outputs
  • Combine stereo signals into a mono signal
  • Divide a mono line level signal into a simulated stereo signal
  • Add a zone

Inputs/Outputs: The TSD-ZDC features two sets of balanced inputs/outputs--one for low impedance (150Ω) devices and one for high impedance (10KΩ) devices, used to split or combine any signal. Each set of connections can be configured as 1 In x 3 Out, 2 In x 2 Out, or 3 In x 1 Out.

Mounting Options: There are several ways of mounting the TSD-ZDC. In addition, two cable retainer straps are included to help make a clean installation. Mounting methods include:

  • Velcro: Self-adhesive, industrial-grade Velcro strips are included in the box for attaching the amp to virtually any flat surface.
  • Brackets: Two mounting brackets are included in the box to secure the amp to a cabinet or wall.
  • Rack Mount: The optional TSD-RMK rack mount panel allows you to mount up to four TSDs in a single 1U rack space.

Specifications:

  • Frequency Response: 20Hz - 20kHz (-1dB)
  • Inputs/Outputs:
    • 150Ω Network: Quantity 4 passive balanced networks; removable 3-position Captive Screw connectors
    • 10KΩ Network: Quantity 4 passive balanced networks; removable 3-position Captive Screw connectors
  • Dimensions: Width: 4" Height: 1.5" Depth: 2.5"
  • Weight: 6 ounces
