both the main speakers and subwoofer. The default volume is 30.
Note: Volume can also be controlled by using the supplied remote.
WARNING: Some manufacturers preset their receivers with the Sub-Out (a.k.a. LFE)
channel signal at a minimum level. It is very important to verify that your receiver Sub-Out
channel is set to the same output level as your front right and left channels. Refer to your
receiver manual for the individual channel level adjustment procedure. If your receiver
Sub-Out channel is set too low, the subwoofer may appear to have a weak output, it may
sound noisy or distorted, and the Auto On/Off feature may not operate properly.

(14) Signal Sensing Auto On/Off Switch
With this switch in the “standby” position, your subwoofer can be safely left with the main
power switched on continuously. The subwoofer amplifier will turn itself on automatically when
an audio signal is present. If no signal is present for approximately 10 minutes, the unit will
switch to standby mode. While in standby mode, your subwoofer amplifier will draw very
minimal power. This function can be disabled by leaving the switch in the “always on” position.

These connections send a crossed-over speaker-level signal to the front speakers. When
connected in this fashion, your satellite speakers will be crossed over at 80 Hz. This removes
the task of reproducing frequencies below 80 Hz from your satellites, enabling them to do a
better job reproducing high frequencies.
You may also connect your satellites directly to your receiver or amplifier along with the
subwoofer if you wish to bypass this crossover.

Rear Panel Connections — Detailed Explanation
T
he SC-602 amplifier is equipped with both speaker-level and line-level inputs. Use the
RCA/Phono type “INPUT” jacks when connecting from a pre-amp, signal processor, or line-level
crossover. The “SPEAKER LEVEL INPUT” jacks connect directly to the speaker outputs of an
integrated amplifier or receiver. Your amplifier section will notice no additional loading effects
when you use these inputs because of their high impedance.
Note: Do not use both the RCA/Phono “INPUT” connections and “SPEAKER LEVEL INPUT”
connections simultaneously.
ABOUT LOW-PASS CROSSOVERS
All of the SC-602 amplifier inputs sum the left and right channels together and the resulting
signal is passed through an adjustable low-pass crossover before being amplified. The crossover
control allows you to adjust the upper limit of the subwoofer’s frequency response from 30 to
160 Hz. The subwoofer’s response will begin rolling off above the frequency you set this control
to. The slope is 24 dB/octave.
You should set the crossover frequency to obtain a smooth and seamless transition from the
subwoofer to the main speakers in your system. If your main speakers are small with limited
low frequency output, you may wish to choose a higher frequency (such as 100 -120 Hz) than
you would with larger speakers which have greater low frequency output. The SC-602 amp’s
crossover has a default of 80 Hz.
Most r
speakers as “lar
speakers. We recommend in most cases setting the main speakers to “small,” despite their
size and frequency response characteristics, allowing all multi-channel bass and LFE signals to
be passed to the SC-602. This is because the powerful 400 (x2) watt SC-602 amp combined
with the SC-600 subwoofer ar
main speakers. With the burden of low frequency reproduction relieved, your speakers will
exhibit better performance, and your overall system performance will improve.
Disabling the Low-Pass Crossover (Subwoofer Direct)
If your receiver/processors provides a crossed-over signal to the subwoofer you may want to
bypass the SC-602 amp’s low-pass crossover. To do this, depress both the Crossover UP and
Crossover DOWN buttons simultaneously. The numeric LED will show

A WORD ABOUT YOUR HOME THEATER RECEIVER’S
CROSSOVER AND THE SC-602 AMPLIFIER’S CROSSOVER
Your Velodyne SC-602 amplifier is designed to operate using the full range audio signal for
input when using the built-in crossover. Many home theater processors/receivers have a
“subwoofer out” jack that performs this same function and are designed to be used with
a powered subwoofer.

n these installations, you may want to bypass the crossover in either the processor or the
Velodyne SC-602 amplifier as described above. However, in some cases you may want to use
B
OTH crossovers. If you choose to do this you should stagger the frequencies, (i.e., 120 Hz
subwoofer, 80 Hz processor) for best results.
Note: If not using an external crossover, you should use the subwoofer’s built-in crossover for
optimal performance. When using a single RCA sub out from the processor, it does not matter
which line level input (L/R) is used.
A WORD ABOUT INTERCONNECT CABLES
When connecting the Velodyne SC-602 amplifier to your subwoofer using the speaker level
connections, use a high quality speaker cable. It is recommended that you keep the length of
cable as short as possible to avoid any potential external interference problems.
When connecting the SC-602 amplifier to your subwoofer, use a quality speaker cable that is
at least 14-gauge. Be very careful to avoid any loose or frayed strands that could result in a
short, causing a dangerous condition and possible damage to your unit. Cables of extremely
large size are typically not required. Extremely large gauge wire may not properly fit in the
binding posts, resulting in a poor connection and possible short circuits.
A WORD ABOUT SUBWOOFER PLACEMENT
Subwoofers operate at extremely low frequencies, which are primarily omni-directional. Keep in
mind that fr
depending on the acoustic properties of the listening room. Typically, the optimum
location for a subwoofer is in a front corner of your listening room where the greatest output
levels and optimum low frequency extension can be found. Typically, a minimum distance of one
to two feet from your TV to the subwoofer will be adequate to avoid any magnetic interference.
equency response and output level can be drastically influenced by r
oom placement,
Remember that the built-in 5-band EQ will help to get the most performance out of your
subwoofer no matter where it is placed.
Caution!
This amplifier is an electronic device. Do not place the amplifier next to sources of heat such
as furnace registers, radiators, etc. Likewise, do not place the amplifier near sources of
excessive moisture such as evaporative coolers, humidifiers, etc. The power cord should be
routed in such a way that it will not be walked on, pinched or compressed in any way that could
result in damaging the insulation or wire.

Selecting the Subwoofer to be Controlled
Y
our SC-602 amplifier can control the Velodyne SC-600 Series subwoofers as well as generic
passive subwoofers. Special internal software settings are designed to maximize performance
and reliability depending on the model of subwoofer being controlled, so it is important to match
the SC-602 amplifier with the subwoofer it is controlling. The SC-602 amplifier comes with a
default setting for the SC-600 IW subwoofer. When the unit is first powered up, the model
setting is displayed for two seconds on the numeric LED before the display reverts to the volume
setting. The subwoofer to be controlled is shown as follows:

the output of the main speakers in your system. This control should be set to achieve similar
volume level of both the main speakers and subwoofer. When pressing volume up or down,
the volume level change is shown on the numeric LED on the front panel.
WARNING: Some manufacturers preset their receivers with the Sub-Out channel signal at a
minimum level. It is very important to verify that your receiver Sub-Out channel is set to the
same output level as your front right and left channels. Refer to your receiver manual for the
individual channel level adjustment procedure. If your receiver Sub-Out channel is set too low,
the subwoofer may appear to have a weak output, it may sound noisy or distorted, and the

Preset 2: R&B – Rock

When you press the presets in the above order, the numeric LED will display “P3” indicating that
you have restored defaults. The unit’s volume is reset to level 30 on a scale of 1 to 80.
Care of your Amplifier
Do not use any harsh detergents or chemicals to clean the SC-602 chassis. Abrasives,
detergents, or cleaning solutions will damage the finish on the SC-602 chassis. We recommend
using a damp cloth to clean the front, back and sides. Do not allow any liquids to enter the
SC-602 chassis.
During normal conditions, the amplifier may be left on continuously without any problems. If you
plan to leave the unit unused for an extended period of time, we r
the unit by the master power switch on the r
ear panel.

Troubleshooting and Service
B
efore seeking service for your amplifier or subwoofer, please re-check all systems. Following
is a simple troubleshooting guide to assist you.
1. Verify that the unit is plugged in and power outlet used is active.
2. Is the power switch on?
3. Is the unit receiving an input signal from your receiver or processor?
4. Have all controls on the amplifier (volume, crossover, phase, etc.) been properly set?
5. If the unit has been running at high levels, one of the protection circuits may be engaged.
Has the amplifier overheated?
6. Has the power button been depressed on the remote?
7. Is the remote non-responsive? We recommend replacing the batteries in the remote.
If the protection circuitry is active, the unit may cycle on and off until operating parameters
return to normal. Under more serious conditions, the unit may shut off completely. Normal
operation should return upon cooling, but you may be required to turn the power off and then
on again to reset the unit.
The following conditions require service by a qualified technician:
1. The power cord has become damaged
2. The unit does not appear to operate normally or exhibits a marked
change in performance
3. The unit has been exposed to water
4. Some par
t of the chassis or circuitry is physically damaged
