INSTALLATION GUIDELINES
1. Please read this owner’s manual
carefully before installing this amplifier.
2. Disconnect the battery ground
terminal prior to making any electrical connections.
3. Check for any hazards or obstructions such as gas tanks, fuel or
brake lines, and wiring harnesses
before mounting the amplifier.
4. Pick a mounting location that will
provide adequate access and ventilation and protect the amplifier
from heat, moisture, and dirt.
5. Avoid sharp metal areas when
routing cables to the amplifier, and
run RCA cables away from the
power cables and other potentially
noisy car harnesses.
6. The amplifier should be grounded
with a short, heavy gauge wire
connected directly to the car at a
bare metal surface, preferably
scraped body sheet metal. Do not
use factory ground locations, seat
bolts, or brackets that are spot
welded.
7. Always fuse your power connection
within 8 to 10 inches of the battery
© 2005 Directed Electronics, Inc. all rights reserved
terminal. Use a fuse or circuit
breaker rated slightly more than the
on-board fuse(s) of the
amplifier(s). The gauge of power
wire used should take into account
the total current draw of the
system, and the length of wire
used. IASCA and other auto sound
competition organizations have
charts available for this; you can
also find a chart in the MECP study
guide. Minimum wire gauge recommendations for the individual amplifiers are listed on the specification
page. Always use the same gauge
wire for the amplifier ground that
you use for the power wire. Be sure
to examine the battery ground
cable of the vehicle, and if necessary, upgrade it by adding an additional ground wire that is the same
gauge as the amplifier’s power
wire. Remember, the amplifier can
only deliver its rated output when it
is not current limited by the power
and ground supply wires.
8. This amplifier is designed to drive a
speaker load that measures from 1
to 4 ohms (D600 2 to 4 ohms).
Keep in mind that heat is the longterm enemy of automotive elec-
5
tronics and the lower your speaker
load, the more heat is generated.
For low impedance speaker applications or restricted ventilation installations, an external cooling fan may
be advisable.
9. Battery and ground connections to
the vehicle should be made with
crimped ring terminals of the appropriate size (surface area is what
counts); soldering the terminals
after crimping is also recommended.
10. Due to the high-frequency MOSFET
switching power supply, filtering the
power cable is not generally
required (remember that the amp
can’t deliver full output if the power
supply is restricted). Proper
grounding of the signal source is
mandatory for the amplifier to
reach its performance peak. If the
RCA inputs are not grounded
adequately via the signal source,
electrical noise from the vehicle
may be picked up in the system.
FRONT PANEL CONNECTIONS/CONTROLS

REAR PANEL CONNECTIONS
1. Fuses - These fuses protect the
amplifier against internal electrical
damage and are meant to protect
the amplifier only. All other power
connections should be fused at the
source.
The D600 uses 1-40A fuse, the
D800 uses 2-25A fuses.
2. (+) 12 Volt Power - Connect this
terminal through a FUSE or CIRCUIT
BREAKER to the positive terminal of
the vehicle battery or the positive
terminal of an isolated audio
system battery.
WARNING: Always protect this power wire by installing a fuse
or circuit breaker of the appropriate size within
12 inches of the battery terminal connection.
2. Remote Turn On - This terminal turns
on the amplifier when (+) 12 volt is
applied to it. Connect it to the remote
turn on lead of the head unit or signal
source.
8
2. Ground - Connect this terminal
directly to the sheet metal chassis
of the vehicle, using the shortest
wire necessary to make this
connection. Always use wire of the
same gauge or larger than the (+)
12 volt power wire. The chassis
connection point should be scraped
free of paint and dirt. Use only
quality crimped and/or soldered
connectors at both ends of this
wire. DO NOT connect this terminal
directly to the vehicle battery
ground terminal or any other
factory ground points.
3. Speaker Terminals - Connect
subwoofers to these terminals.

PARALLEL SYNCED GAIN CONNECTIONS/SETTINGS
Refer to figure 5 for wiring details.
1. Input Signal - Connect these RCA
jacks as described in the Front Panel
Connection section of this guide.
2. Slave/Master Switch
Set the slave/master switch
on the master amplifier to the
MASTER position.
„
Set the slave/master switch
on the slave amplifier to the SLAVE
position.
„
Setting the slave/master
switch on both amplifiers will automatically set the I/O RCA jack
configuration according to each
amplifier’s slave or master designation.
„
NOTE:
One master amplifier can control up to three slave
amplifiers in this combination. Multiple identical
master/slave combinations can be added to any
given system.
3. Phase Switch - Set the phase
switches of all synced amps to the
same position (all at 0° or all at
180°).
© 2005 Directed Electronics, Inc. all rights reserved
4. In order to achieve safe, optimal performance, the LPF, Bass EQ, and Subsonic
Filter controls on all synced amps must
be set to the same position.
5. Signal Connection - Connect an RCA
cable between the OUT RCA jack of
the master amplifier and the SLAVE
IN RCA jack of the slave amplifier as
shown in the Figure 5.
6. Subwoofer Speaker Connection - In
this amplifier combination each
amplifiers must drive its own separate subwoofer(s). Connect the
speaker terminals of each amplifier
to any combination of one or more
subwoofers that results in nominal
impedance between one and four
ohms (D600—2 to 4 ohms).
Make sure that each amplifier sees
the same speaker impedance.
WARNING: The amplifier’s gain control is bypassed completely
in SLAVE mode. Do NOT move the MASTER/SLAVE
switch to SLAVE position when the amplifier is
connected and playing. Do NOT connect any signal
source to the amplifier in SLAVE mode that
exceeds 200mV.

CROSSOVER SETTINGS AND GAIN ADJUSTMENT
Your Directed Audio power amplifier
needs to be adjusted carefully to
achieve maximum performance. These
are some guidelines to follow when finetuning the amplifier.
„
Because this amplifier is only
designed for subwoofer applications, the low-pass crossover is
active at all times. The crossover
point is adjustable to allow more
precise system operation.
„
Try and keep the setting low
enough to prevent image smearing
(you should not be able to hear
male voices from the subwoofer)
but not so low as to create a gap
between the subwoofer and the
mid-bass/midrange speakers. It
will be to your advantage to spend
some extra time with this adjustment, listening to familiar music or
system set-up discs to achieve the
kind of musical reproduction that
you prefer.
„
12
The gain adjustment allows you to
set proper signal match for clean,
quiet amplifier operation. Start by
playing some music you are
familiar with. With the gain adjustment on the amplifier in the middle
of its rotation, bring up the volume
on your head unit to the 3/4
volume setting or until you start to
hear distortion or clipping. If you
hear distortion before you reach the
3/4 volume setting of your head
unit, reduce the gain setting on the
amplifier and start to raise the head
unit volume again. When you can
listen to the music at or slightly
above 3/4 on your head unit
without audible distortion, slowly
raise the gain of the amplifier until
distortion is heard, then back off
the gain until the distortion is not
audible. This setting will allow you
to reach full output with all but the
quietest of source material, while
avoiding excessive noise in the
system.
„
For systems using the Remote Sub
Level Adjustment, increase the
subwoofer gain on the amplifier by
25% and set the Remote Sub Level
knob to the center position after
making all system gain and filter
adjustments. This will give the
Remote Sub Level Control a wider
range of adjustment to the
subwoofer output.
„
You should take into consideration
the effect that gain adjustment has
on system frequency response and
staging. Again, plan on spending
some time with music that you
know getting the gain and
© 2005 Directed Electronics, Inc. all rights reserved
crossover settings the way you like.
Test discs and analyzers may help
with this process, but in the end it's
your ears that count --listen to the
music!
