FUNCTIONS

STATUS -

These lights indicate when the ampliﬁer is powered up normally and when there is a protection fault. The Protect

LED is illuminated when there is a problem with your ampliﬁer. Please contact your authorize DAT dealer or call DAT's technical support.

GAIN -

This control matches the preamp stage of the Diamond Audio ampliﬁer to your source unit. This is NOT a volume control.

The range is between approx. 0.15mV to 12V. Use a speaker to RCA adapter (NOT an LOC!).

INPUT CONFIG -

or from an auxiliary device (like a Smartphone, etc). The 5 channel model (DES1000.5D) is set up to accept 2/4/and 5 channels of input.

TURN-ON MODE -

REM, DC and VOX. 1 - (REM) is the standard 12V trigger wire, 2 - (DC) or DC offset, when connected high level in, will sense differences in

ground in your wiring through the speaker leads and turn on ampliﬁer, 3 - VOX (signal sensing) which will sense any signal input into the

ampliﬁer RCA input - turning on the ampliﬁer.

INPUT LEVEL -

This switch allow you to select HI or LO depending on the signal used. HI is used when you use speaker level

input. LO is when you use RCA input from an aftermarket headunit.

XOVER -

This switch allows you to select the crossover function. HPF (High Pass Filter) LPF (Low Pass Filter) or FLAT(no ﬁlter),

HPF is for ﬁltering out bass for midrange/mid bass drivers. LPF is for ﬁltering out hIgh frequencies for subwoofers.

FREQ -

Use this adjustment to select the crossover point LPF/FLAT/ or HPF. Remember that you must select the crossover function

FIRST to get any adjustment. The range of adjustment is limited between 35-350Hz @12dB per octave .

BASS BOOST -

may not be able to handle the additional low frequency boost.

RCA INPUT (PRE INPUT) -

(RCA's). Simply connect to the source unit using RCA type audio cables (twisted pair is recommended), or use speaker to RCA adapters.

Make sure to keep them away from power wiring wherever possible to reduce risk of noise.

RCA OUTPUT (PRE OUTPUT) -

This is available on the following DES ampliﬁers - DES400.2D/400.4D/1000.1D. It is NOT processed, and is full range/Unity Gain.

PHASE-

This control gives the installer a unique feature that allows the variable adjusment of phase 0-180 degrees to compensate for

subwoofer placement. Allowing the subwoofer to sound like it's placed in the front of the vehicle instead of the trunk.

BASS REMOTE -

user to control the level of gain up to the maximum adjustment level set on the ampliﬁer for the subwoofer output. The control does not

add additional boost, it only attenuates the setting that is ﬁxed at the ampliﬁer's control panel.

BASS REMOTE "Slave" -

ONE (1)remote level contrrol!

SPEAKER OUTPUT -

the LEFT + and RIGHT - as the two connections. The 2 and 4 channel ampliﬁers will perform into 4 and 2 Ohm stereo loads or 4 Ohm

bridged loads. DO NOT run 2 Ohm bridged loads on these ampliﬁers! The mono blocks will run 1 ohm mono.

POWER INPUT -

power and ground connections. 4 Guage is recommended for the mono block. The terminals will handle up to 4 gauge wiring

with no problem whatsoever. Be sure any wiring that passes through metal has a grommet! DO NOT USE CCA power/ground wire!!

FUSES -

Fuses are installed on ALL DES amplifers to protect ...the VEHICLE! They do NOT protect the ampliﬁer. This is true of every ampliﬁer

built today. IF you "blow" fuses, then check your electrical system. AGAIN - make sure you DO NOT use CCA wire power kits!!!

This switch parallels the input circuit if you are using a single stereo pair of outputs from your headunit

This switch allows you to conﬁgure the "Turn-On Mode" switch for desired turn-on trigger. There are 3 modes available:

This control adds 0 to +12dB of Bass boost at 45Hz. Be cautious when adding boost to subwoofer systems as they

The RCA jacks allow for a normal Left and Right channel signal input. Both HI (speaker level) or LO

These RCA output jacks allow for Left and Right channel signal pass thru to a secondary ampliﬁer.

All DES amplifers have this port for the remote level control (included). The control is intended to allow the

Connect your speakers to these terminals. Stereo connections are connected as labeled. Bridged connections use

These connections are for input power, chassis ground, and remote turn-on. Use a minimum of 8 gauge wiring for
