WIRING, CONNECTIONS & SETTINGS
It is important to read this manual thoroughly before starting your installation and always plan accordingly.
Before installing, disconnect the negative (ground) wire from the vehicle’s battery to avoid damage to the
vehicle or yourself. Following all guidelines will help provide years of enjoyment with your S amplifier.TEG
ŒPower Supply Terminal
Ground (GND): ground
Ÿ The terminal must be connected to a metal part of the vehicle with ground
plane back to the main battery ground attachment point (a.k.a. chassis ground). This wire should be as
short as possible, but no longer than 2ft (60cm), with 8minimum gauge of AWG. The ground wire
should be terminated ground specific or ring terminal and securely bolted to the vehicle with with a
star or lock washer and nut to prevent from coming loose. The chassis ground connection point
should be scuffed to the bare metal.
ŸPower (+12V): The constant +12V power connection must be made at the vehicle main battery,
securely connected with a ring terminal and protected with an in-line fuse within 18in (45cm) from the
positive battery terminal. The requires a 0A fuse while the requires A fuse, with SDSP6 3 SDSP8 a 50
minimum gauge of 8AWG. Do not install the fuse until all other system connections have been made.
Fuse(s):
 The built-in ATC fuse(s) are to protect the amplifier and must be inserted for operation. When
replacing fuse , first check for system wiring faults and always use the specified value for each fuse. The (s)
SDSP6 SDSP8 25 model requires one 30A fuse, while the requires two A fuses.
Power/Protect LEDs (POW/PRO): Green
ŽThese LEDs indicate the amplifier’s operating status. indicates
the amplifier is on and in normal operation. indicates the amplifier is in protection mode, due to Red
overheating, under/over-voltage output short circuit, etc.,
Turn-on Mode Select:
 This switch is for selecting which method is used for turning on the amplifier. The
default setting ACC ON is for a switched +12V wire connected to the REM IN wire in the REM + SPEAKER
OUT terminal. If a wired trigger is unavailable, select AUTO ON for detection from the high DC-offset
level inputs for automatic turn-on. If the high level inputs or the source does not contain are not used
DC-offset, a +12V switched trigger .connected to REM IN will be required
High-Level/AUX/Coax Input & Pre-out Terminal:
 This terminal/harness is for high level input signal
connections from the main source, as well as inputs for a 2-channel low level AUX source and a digital
coax source. If connecting to an additional amplifier, this harness also provides a 2-channel RCA pre-out
connection. Note that for SDSP6, the pre-outs are assigned to CH5/6 outputs in the DSP software, while
in the SDSP8 they are assigned to CH7/8 outputs. Use quality interconnects to ensure stable connections
and minimize the possibility for induced noise.
High-Level Input Gain Adjustments:
‘ These adjustments provide a 0dB (max) to -6dB (min) attenuation
range for the high-level inputs. Unlike traditional amplifier gains, these adjustments only provide
attenuation and do not affect S/N, so should be set at maximum unless attenuation is desired vs. other
input sources, or if level matching is required between input channels when summing signals from a
high-level source. Note that the maximum signal voltage the high-level inputs can accept without
clipping the A/D converters is 10Vrms, no matter the position of these adjustments. Also note that the
high-level source must contain DC-offset or the maximum input signal voltage will be reduced to 3Vrms.
Although the vast majority of OEM radios and factory amplified systems utilize BTL chipsets that provide
signals with DC-offset, Class-D or high voltage factory systems do not, and therefore will require external
attenuation such as with a voltage divider.
Bluetooth Port:
’ This USB terminal is for connecting the optional Bluetooth dongle (sold separately) as
an additional input source for SDSP6 and SDSP8.
Optical Input:
“ This optical port is for connecting an external source with an optical (Toslink) cable as an
additional input source for SDSP6 and SDSP8
Speaker Output & Remote In/Out Terminal: that channel of
” Each (+) and (-) wire pair is for connecting
the amplifier's output to speaker(s) or subwoofer(s). Make sure to observe correct polarity and total
impedance per channel. The minimum nominal impedance is 2 per channel. If the source unit has a Ω
remote output wire or if a switched ignition wire is available, connect it to the REM terminal for turning
on the amplifier and select ACC ON from the turn-on mode switch . ❹
Remote Control: J port
• This R 45 is for connecting the optional DRC digital remote controller (sold
separately), which remote control of the SDSP6 and SDSP8 provides for source select, master volume,
sub volume, mute and preset load.
USB PC Control: This USB Type-B port is for connecting to a Windows PC with the supplied cable to run
•
the DSP tuning software and make changes to the internal settings. Note that if the optional DRC
remote is also connected, it is recommended to not use it while connected to the PC software.
Note: If more than one source is connected, the optional DRC is required to change sources without the PC
software. If only one source is connected, select it from the PC software during initial setup.

SOFTWARE INSTALLATION
Once the DSP tuning software is open and is connected to the main unit, any adjustments will be made to
the DSP in real time. It is recommended to periodically save your settings to a preset (POS1-POS8) and save
the *.DSP6-8Set setup file to PC via the file menu as backup once all settings and presets have been written.
Please familiarize yourself with the available settings in the following section and carefully consider each
adjustment for your source and connected speakers. If your system is different than the factory default
settings, it is recommended to first select a speaker configuration or choose speaker OUTPUT type by ①
channel to automatically apply pre-set crossovers to ④
protect sensitive speakers such as tweeters. Next choose
the input CH SETTING ③ or the appropriate INPUT
routing by channel for your high level source All of ④ .
these settings can be manually changed later as needed.
Note that it is not recommended to make any adjustments
from the optional DRC remote (if also connected) while
making changes from the PC software.
DSP SOFTWARE & SETTINGS

Speaker Configuration & Channel Selection Image: This section with speaker images and vehicle

positions represents the settings made in its pull-down menu that provides pre-set speaker
configurations as well as any manual changes made to speaker output type made in section ④. The
currently selected output channel in section ④ will highlight the associated speaker image/location.
Source Select:
‚ This section provides for direct selection of the input source. The currently selected
source name will be highlighted. The default source selection is high level input (MAIN). To change
source without the PC software connected, the optional DRC is required.
Input channel settings: This section provides a quick method for setting the input channel routing as
ƒ
2CH, 4CH, 6CH or MIX (3-way sum). To make further changes to input signal routing to individual
channels, use the adjustments in section ④.
Input Channel Routing, Output Channel Assignment and Pink Noise Generator:
„ In this section, all
signal routing and channel assignments can be made for each individual channel, or if channel pairs
linked, as well as generate pink noise to the selected outputs for the purpose of tuning the vehicle
acoustically with an RTA or audio spectrum analyzer.
cont
ŸFor input signal routing, the drop down tabs under the INPUT column ain selections for FL, FR, RL,
RR, Sub L, Sub R channels connected to the high-level input . input channel harness Any can be
assigned to from any output channel, or mixed (summed) for the purpose of creating full-range signals
2-way or 3-way factory signals, a mono signal for center or sub, or creating a non-faded generating
output by summing front and rear signals.
For output channel assignment, use the drop down tabs under the OUTPUT column. Selecting a
Ÿ
particular channel output assignment is for the purpose of master volume and sub volume control
from the PC software or optional DRC. Assignments can be made in any order except for CH7/8, which
are the only channels assignable as subwoofer and controlled by the sub volume adjustment.
Therefore, while the SDSP6 has 6-channels of powered outputs (CH1/2, CH3/4, CH7/8), its preouts
(CH5/6) are not assignable as subwoofer channels. See pg.9 for an example of using the SDSP6 with an
external mono amplifier. For the SDSP8 with 8-channel of powered outputs, where CH7/8 may be
assigned as the subwoofer channels, any sub level adjustment will also affect the CH7/8 preouts.
ŸFor speaker type, each available choice provides a pre-set crossover that will be applied for the
purpose of initial protection until full system adjustment is made. Any crossover can be adjusted
manually afterward in section ⑤ or from the graph in section ⑨.
ŸFor convenience in making acoustic measurements, a pink noise generator is available for each output
channel under the TEST column. When activated, the input signal is temporarily bypassed to provide
pink noise from the selected output channels.
Crossover Type and Frequency: This section is for selecting crossover type and frequency for the
…
currently selected channel in section ⑦. Crossover type is selectable as OFF, HP, LP or BP, which activates
both HP and LP crossovers simultaneously as a bandpass. Cut-off frequency can be entered manually in
the numerical boxes or the sliders in this section, as well as via the graph in section ⑨.
Filter Model and Crossover Slope: In combination with the crossover type and frequency adjustments
†
in section ⑤, this section allows selection of filter model (Linkwitz, Bessel or Butterworth) for the
currently selected channel in section ⑦, each of which provides a different filter Q, slope options and
associated phase response. Note that slopes not available for the currently selected filter model are
highlighted in light gray, while available slope choices are in dark gray.
Master Volume, Sub Volume and Channel Trim Levels: When the GAIN button is selected, volume and
‡
trim levels will appear in this section. The master volume slider is for adjusting output volume of all
channels together, while the sub volume will only affect CH7/8 relative to the master volume up to
+12dB (if assigned as such in section ④. Volume adjustments may also be made via the optional DRC
when not connected to the PC software. The individual channel trims are for adjusting each channel’s
output level relative to the other channels for the purpose of tuning the system with the connected
speakers in the vehicle.
Time Delay and Phase: When DELAY is selected in section ⑦, this section will replace it on the screen
ˆ
for adjusting time delay and phase for each channel. Delay increments can be chosen as time in
milliseconds (MS) or as distance in centimeters (CM) or inches (INCH). After adjusting for imaging with
individual channels, note that channels can be linked for adjusting together while keeping their
individual delay settings, simplifying tasks such as delaying main speakers relative to subwoofer(s) in
order to achieve up-front bass and better staging. Phase allows polarity of individual channels to be
flipped without affecting delay settings.
Parametric EQ and Frequency Response Graph: This section contains 31 bands of parametric EQ
‰
adjustments for each output channel, as well as providing a visual representation of all crossover and
PEQ settings. The boost/cut, frequency and Q (width) of each PEQ band can be set by the sliders, while
boost/cut and frequency can also be dragged by mouse on the graph for adjustment. Channel select
buttons on the right side can show individual channels or multiple channels overlaid simultaneously.
Preset Read/Write: Up to 8 presets can be saved (WRITE) to the POS1-POS8 buttons, where they can be
Š
loaded from memory (READ) to override current DSP and PC software settings. Note that master volume
and sub volume are not saved to presets and will be overridden if remote control from the DRC is used.
Also note that all presets will be saved in the *.DSP6-8Set program file if saved to the PC under the file
menu at the top left corner of the screen.

SDSP6 SYSTEM EXAMPLE: 4-IN/8-OUT
Note: In this system example, all 6-channels of the SDSP6’s powered outputs are used for front 2-way
components and rear full-range speakers. For adding a subwoofer amplifier, the CH5/6 preouts may be
used. Depending on the available input channels, the signal feeding CH5/6 may be derived as a sum of the
front and rear input signals from a 4-channel source as shown. However, since the SDSP6’s CH5/6 preouts
are not assignable as subwoofer channels for the purpose of sub volume control from the optional DRC
remote, a separate RLC for the subwoofer amplifier is needed if remote sub level control is desired.
