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
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).
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.
