MicroVee User’s Manual
P l a c e m e n t o f Yo u r S u b w o o f e r
The first step in installing your new MicroVee is to determine where it will be placed in the room.
Unpack the system carefully and use the following guidelines in order to find the best room
placement option.
True subwoofers operate at extremely low frequencies which are primarily omni-directional.
Keep in mind that frequency response and output level can be drastically influenced by
placement, depending on the acoustic properties of the listening room. To obtain optimum
output from your subwoofer, place it within a foot of a corner. This location will offer the greatest
output levels and optimum low frequency extension. If at all possible, your subwoofer should be
placed along a wall. The worst location for a subwoofer is typically far away from any walls and
close to the center of your room. Avoid these locations when possible. When using a pair of
Velodyne subwoofers in stereo, it is preferable to place each subwoofer near the satellite of the
same channel.
Depending on the size and type of furnishings in the room, perfect placement may not be possible.
Finding the best location within your environment will likely require some experimentation. We
suggest you experiment with the location during setup to find what sounds best to you when seated
in your typical listening position.
Regardless of where you install your Velodyne subwoofer, it must remain in an upright position
(woofer facing forward). Using, shipping or storing the subwoofer in any other position for an
extended period of time may result in damage to the unit not covered by warranty.
Caution! This subwoofer has electronics built into the cabinet. Do not place the cabinet
next to sources of heat such as furnace registers, radiators, etc. Do not place the unit
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.
MicroVee User’s Manual
I n s ta l l a t i o n
Your new Velodyne subwoofer provides for a number of installation options. Read all the
installation information below in order to determine which installation option is best suited for
your system. Remember to perform all installation procedures with system power turned
off to prevent possible damage.
Figure 1. MicroVee Back Panel
Important!!! Insure that the subwoofer is only connected to the rated source voltage.
Do not connnect the 120-volt version to 230-volts or vice-versa. This will result in
damage to the subwoofer and possible injury to the user.
Your new subwoofer is equipped with speaker-level, line-level, and MINI-JACK inputs. Use the
LINE LEVEL jacks when connecting your subwoofer to a pre-amp, signal processor, line-level
crossover or receiver with pre-amp level outputs. The SPEAKER LEVEL jacks connect directly
to the speaker outputs of any amplifier, integrated amplifier or receiver. Your amplifier section
will notice no additional loading effects when you use these inputs due to their very high
impedance. Use the MINI-JACK inputs when connecting to a docking station or personal
audio system.
Important!!! Do not use any of the LINE LEVEL, SPEAKER LEVEL, and MINI-JACK
connections simultaneously!
MicroVee User’s Manual
This connection passes along the input signal from the MINI-JACK input unchanged.
Speaker Level Output
These speaker level connections connect to your main speakers. There is 120 Hz high-pass
crossover that removes the bass frequencies from your main speakers. This frees them of the
burden of playing bass, which makes the entire system perform better.
Volume Contr ol
This control allows you to balance the output from the subwoofer to the main speakers in your
system. This control should be set to achieve similar output level from both the main speakers
and subwoofer when listening to music. A good starting point for the volume control is three or
four dots from minimum.
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
Auto On/Off feature may not operate properly.
Low-pass Crossover - 50 to 200 Hz
All inputs sum the left and right channels together, with the resulting signal passing 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 50 to 200 Hz. The subwoofer’s
response will begin rolling off above the frequency you set this control to. 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 smaller 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. With larger speakers, you might start
with this control set lower, such as 80 Hz.
Phase Adjustment - 0°/180°
This control allows you to “reverse” the phase of the subwoofer’s output signal 180° to correct
for any possible mismatch and resulting cancellation between the subwoofer and your main
speakers. To adjust, simply listen to the system with music playing. Then move the switch from
one position to the other and listen for a change in low frequency output. The correct position
will have a greater amount of apparent low frequency output.
This switch allows the MicroVee’s internal crossover circuitry to be bypassed. This is required
in certain installations which route the signal through external processors with a crossover
circuit of their own. Simply move the switch to SUBWOOFER DIRECT to disengage the built-in
crossover. For all other installations which do not have a separate electronic crossover, we
recommend you leave the switch set to INTERNAL X-OVER to provide optimum performance.
NOTE: This is explained further in the section below entitled “A Word About Crossovers”.
MicroVee User’s Manual
A u t o Tu r n O n F u n c t i o n
With this function in the “active” position, your subwoofer can be safely left with the main power
switched on continuously. The subwoofer will turn itself on automatically when an audio signal
is present. If no signal is present for approximately 15 minutes, the unit will switch to standby
mode. While in standby mode, your subwoofer will draw very minimal power. This function can
be disabled by leaving the switch in the “inactive” position.
WARNING: If the Sub-Out channel signal level from your receiver is too weak, this feature will
not operate properly. See VOLUME CONTROL section on previous page.
Power Switch
The master power switch is located on the lower half of the unit. This rocker style switch is the
main on/off control for the unit. This switch should be set to position 1 (up) for on, and
0 (down) for off. If the unit is to be left unused for an extended period of time, the master power
switch should be turned off.
A Wor d About Cr ossovers
The MicroVee is designed to operate using the full range audio signal as input. Some
processors/receivers have a “subwoofer out” (or LFE) jack, which is the ouput of the receiver’s
crosssover, that is, signal that has already had the upper frequencies removed. Consult your
receiver’s owner’s manual on adjusting this setting. In some rare cases, combining both the
receiver’s crossover and the one internal to the subwoofer may result in low output and
increased noise. In these installations you may need to bypass the crossover in either the
processor or the MicroVee. In some installations, simply setting one crossover to a higher
frequency (such as 120 Hz) will restore maximum performance. To bypass the subwoofer’s
internal crossover when the unit is being fed a low pass signal from another crossover, simply
locate the switch marked INTERNAL X-OVER/SUBWOOFER DIRECT on the rear panel of the
subwoofer and set to the SUBWOOFER DIRECT position. This will eliminate the MicroVee’s
crossover from the signal path.
MicroVee User’s Manual
LFE Connection - Option A
Figure 2 shows connection from your home theater receiver to the LFE input on the back of
your subwoofer. When the subwoofer is installed in this fashion, all of the low frequency
information from your “LFE Out” or “Subwoofer Out” on the back of your receiver will pass into
your Velodyne subwoofer. This connection is the most common connection method when using
your subwoofer with a 5.1 receiver. (Cable needed: 1 mono RCA cable.)
Figure 2. Installation Using LFE Line-Level Inputs
MicroVee User’s Manual
A Wor d About The Auto On/Off Featur e
When using a single channel input (such as a surround sound processor’s subwoofer out or
LFE), the auto on/off circuit sensitivity will be affected. When one input channel is used instead
of two, the unit will see lower signal levels present at the inputs. This may cause the unit to
turn off inadvertantly when listening at low volume levels and/or not “wake up” even when signal
is present. If this occurs, simply use a “Y” adapter (available from most dealers) to allow your
processor’s single sub line to be fed into both L&R inputs. This will make the unit turn on at
lower signal levels.
MicroVee User’s Manual
Mini-Jack Connection - Option B
Figure 3 shows connection from your audio player or gaming console output to the MINI-JACK
of your Velodyne subwoofer. Use the supplied cable to connect from the output of your dock,
computer or gaming console to the input jack of the MicroVee. Connect the satellite speakers
into the thru-jack on the back of the MicroVee subwoofer. (Cable supplied by Velodyne: 6 foot,
1/8” (male) to 1/8” (male) stereo cable.)
Figure 3. Installation Using Mini-Jack Line-Level Inputs
MicroVee User’s Manual
Speaker-Level Connection - OPTION C
Figure 4 shows an easy way to connect your Velodyne subwoofer directly to your receiver or
integrated amplifier if it lacks line-level outputs. You may also connect your satellites directly to
your receiver or amplifier along with the subwoofer. Your receiver or amplifier will not notice the
additional load of the subwoofer due to the high input impedance.
When the subwoofer is installed in this fashion, your satellite speakers will be crossed over at
120 Hz which removes the lower bass frequencies from your speakers, enabling them to do a
better job reproducing the higher frequencies.
Figure 4. Installation Using Speaker-Level Inputs
MicroVee User’s Manual
Caution!!! To avoid damage to your main amplifier, be sure to maintain correct polarity
when making all connections. Red (positive) to red, and black (negative) to black. Be
sure that all connections are tight, and that there are no loose strands or frayed wires.
Interconnect Cables
When installing your new Velodyne subwoofer using the line level connections, you should always
use shielded phono cables. There are many quality cables available. We recommend that you
keep the length of cable as short as possible to avoid any potential noise problems.
When using speaker level connections, use a quality speaker wire that mates well with the
connectors. Be very careful to avoid any loose strands or frayed wires which may result in a
short which may in turn, damage your equipment. Extremely large gauge wire may not properly
fit in the binding posts, resulting in a poor connection and possible short circuits.
C a r e o f Yo u r S u b w o o f e r
Your Velodyne subwoofer does not require any regular maintenance. Normal dusting or cleaning
of the surface for appearance purposes are all that is required. We suggest you avoid any harsh
detergents or chemicals when cleaning the cabinet. Abrasives, detergents, or cleaning
solutions may damage the finish on the cabinet. We recommend using only a damp cloth to
clean the cabinet.
During normal conditions, your new subwoofer may be left on continuously without any
problems. The unit is equipped with a signal-sensing turn on/off that will automatically turn on
the unit when a signal is present at the inputs and turn off the unit after several minutes when
there is no longer any signal at the inputs. If you plan to leave the subwoofer unused for
an extended period of time, we recommend that you turn off the master power switch on the
rear panel.
Protection Circuitry
Your new subwoofer is equipped with special protection circuitry to provide maximum
performance with greatest reliability.
The unit is protected against:
1) Overdriving the speaker or amplifier
2) Overheating the amplifier
3) Excessive drop in power line voltage
The first type of protection circuitry which prevents overdriving of the speaker or amplifier
operates constantly without being audible under most situations. In some extreme situations
(sustained high output levels such as pro sound usage), the unit may shut down momentarily.
This indicates the thermal or under-voltage protection circuitry has engaged. If this should
happen, you should reduce the volume setting or shut the unit off until normal operating
conditions return. You may also want to plug the unit into a different wall outlet, as dropping
power line voltage will be most noticeable under strenuous conditions and may result in the unit
shutting down intermittently.
MicroVee User’s Manual
T roubleshooting and Service
Before seeking service for your amplifier or subwoofer, please re-check all systems. Following
is a simple troubleshooting guide to assist you.
Verify that the unit is plugged in and power outlet used is active.
Is the power switch on?
Is the unit receiving an input signal from your source?
Have all controls (volume, crossover, phase, etc.) been properly set?
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. Make sure binding posts are tightened.
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 part of the chassis or circuitry is physically damaged
