wires inside the vehicle, hidden from passengers. An exposed wire can inadvertently be pulled out, and may cause disconnection or shorting.

location and Mounting

The DTAl is compact in size and it generates virtually no heat. It can be located almost anywhere within the passenger compartment, trunk, or storage area. However, do not install the DTAl in the engine compartment or in any outside location exposed to dirt and moisture.

Use the DTAl as a template to mark drill holes. Before mounting the DTAl to your vehicle’s chassis, inspect the site for any hidden brake or gas lines, wires, or cables.

After selecting a suitable location, mount the DTAl , and then per- form the following connection steps:

Connecting Audio Signal Cables

1.Make sure power to your audio system is off.

2.Locate the Digital Output connector on the back of your CD or DAT control head unit.

3.Connect an appropriate length of RCA coaxial cable from the source’s digital output to digital 75 R input 1 on the DTAl

NOTE: If you use an optical link, connect an appropriate length of fiber-optic cable from the source’s digital output to the Optical input

on the DTAl . However, if you are installing a second source, remem- ber that the DTAl uses automatic priority switching to select signals at Optical input over those present at the 75 ohm inputs, 1 or 2. Also, input 1 has priority over input 2. However, CD players not equipped with o Remote On/Off control will continue generating

7.Connect another (e.g., orange or aqua) wire from the Remote terminal to your control head unit’s remote turn-on connection.

NOTE: This connection enables the DTAl to follow a timed sequence for minimal turn-on and turn-off thumps and is required for circuit activation.

8.Connect a red wire (18 gauge) from the +12V terminal through a 0.75 A in-line (fast-blow) fuse, to a constant +12 Vdc source, so that it is “hot” even when the ignition is off. Try connecting it to the battery cable itself, or tapping into a power lead on the control head unit (see Figure 3).

DTA 1 Operation

9.Turn on your control head unit, selecting a source connected to the DTAl, and slowly increase the volume while listening to a familiar musical selection. With proper instollation, your DTAl should pro- vide you with an increased sense of transparency and music repro- duction. There are no adjustments or controls.

NOTE: If you experience problems at this point, review the installa- tion steps and check all your connections. If you are installing the DTAl as part of a new system, try leaving the DTAl out of the chain until you get your entire system operating properly first. Then repeat steps 1 through 8 to insert the DTAl once again into the audio system chain.

SERVICE Your DTAl is protected by a limited warranty. Please read the enclosed warranty information carefully. Should any problem occur, contact your local Soundstream dealer.

digital sync code which will be sensed by the DTAl. If this type of player is part of your installation, we suggest connecting the unit to a lower priority input via RCA cables.

4.Repeat steps 2 and 3 to connect an additional CD or DAT control head unit.

5.Connect an appropriate length of high-performance stereo RCA audio cable from the Left and Right analog audio outputs on the DTAl to the CD or Aux input of your head unit or preamp in your mobile system chain (see Figure 3).

Connecting Power Wires

6.With power still off, connect a black wire (18 gauge) from the Ground terminal to a good chassis ground (e.g., bare metal or bolt, not painted or coated).
