Rear Panel Connections — Detailed Explanation

T

he SC-600 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-600 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-600 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-600. This is because the powerful 400 watt SC-600 amp combined with
the SC-600 subwoofer ar
speaker. 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/processor provides a crossed-over signal to the subwoofer, you may want to
bypass the SC-600 amp’s low-pass crossover. To do this, depress BOTH the Crossover UP and
Crossover DOWN buttons simultaneously. The numeric LED will show
low-pass crossover has been defeated. To reactivate the low-pass crossover, simply push the

A WORD ABOUT YOUR HOME THEATER RECEIVER’S
CROSSOVER AND THE SC-600 AMPLIFIER’S CROSSOVER

Your Velodyne SC-600 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

I

n these installations, you may want to bypass the crossover in either the processor or the
Velodyne SC-600 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 installing your Velodyne SC-600 amplifier using the line-level connections, you should
always use high quality shielded interconnect cables. 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-600 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. This location will usually
offer the greatest output levels and optimum low frequency extension. Typically, a minimum
distance of one to two feet from your TV to the subwoofer will be adequate to avoid any
magnetic inter

equency response and output level can be drastically influenced by r

ference.

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-600 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-600 amplifier with the subwoofer it is controlling. The SC-600 amplifier comes with a
default setting for the SC-600 IW subwoofer. When the unit is first powered up, the model
being controlled 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:

Remote Control

The features of the SC-600 remote control are listed below.

• POWER — This button forces your SC-600 amplifier unit into

standby mode. The power LED turns amber, the numeric LED
shuts off, and the amplifier puts out no power. The unit will
remain in this mode until the POWER button is pressed again.
To fully deactivate (i.e. power down) the unit, use the main
power switch on the back panel.

Note: The master power switch on rear panel must be on in
order for the front power button to function.

• MUTE — This button mutes the subwoofer’s output. The LED

on the amplifier will show 00 if the unit is muted. To unmute
the subwoofer, press the MUTE button again and the original
volume setting shows on the LED.

• EQ — This button automatically EQs the subwoofer using a 5-band internal graphic equalizer.

To use this feature, first plug the supplied micr
of the amplifier and place the mic in your preferred listening position. Then press EQ on the
remote for about 2-3 seconds. The subwoofer emits 12 “sweep tones” that cover the
frequencies between 20 and 150 Hz. The LED displays “AU” during the Auto-EQ process.

Care of your Amplifier and Subwoofer

Do not use any harsh detergents or chemicals to clean the SC-600 chassis or the subwoofer
cabinet. Abrasives, detergents, or cleaning solutions will damage the finish on the SC-600
chassis or the subwoofer cabinet. We recommend using a damp cloth to clean the front, back
and sides.

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 source?

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

Thank You for Purchasing an SC-600 Amplifier!
