				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.   
					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 units 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.   
					Your new Velodyne subwoofer, like any good speaker system, requires   
					proper positioning within the listening space to provide maximum   
					performance. Improperly placed speakers may degrade the sound   
					quality and reduce your listening pleasure. 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.   
					A bypass switch is also provided if you wish to use an external   
					crossover. If you are not using an external crossover, we   
					recommend that you use the one provided within the unit for   
					optimum performance!   
					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/amplifier.   
					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.   
					INSTALLATION   
					Inputs   
					Your new subwoofer is equipped with speaker-level and line-level 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.   
					Crossover Switch - INTERNAL X-OVER/SUBWOOFER DIRECT   
					This switch allows the internal crossover circuitry to be removed from the   
					signal path. This is required in certain installations which route the signal   
					through external processors with a crossover circuit of their own, such   
					as the new digital units. 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.   
					Important!!!   
					Do not use both LINE LEVEL and SPEAKER LEVEL   
					connections simultaneously!   
					Volume Control   
					This control allows you to balance the output from the subwoofer to the   
					main speakers/amplifier 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 3   
					or 4 dots from minimum.   
					Auto Turn on Function   
					With this function in the “auto” 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 10 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   
					“on” position.   
					Low-pass Crossover - 40 to 120 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 40 to 120 Hz. The

				Power Switch   
					The master power switch is located on the lower half of the unit. This   
					rocker style switch is the main on/off 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.   
					TM   
					Subwoofer Outputs   
					SUBWOOFER   
					VOLUME   
					The Velodyne subwoofer is designed to operate using the full range   
					audio signal for input when using the built-in crossover. Some   
					processors/receivers have a “subwoofer out” jack that is internally   
					filtered and designed to be used with a conventional amplifier and   
					speaker. In some rare cases, combining both an external 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 internal   
					crossover in either the processor or Velodyne subwoofer. 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   
					internal crossover from the signal path.

					LINE-LEVEL CONNECTION - OPTION A   
					Figure 1 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.)

				Note: If not using an external crossover, you should use the built-   
					in crossover for optimal performance. 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   
					when listening at low volume levels. 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.

					Figure 2 shows connection from a pre-amplifier’s main outputs to the left   
					and right inputs of your Velodyne subwoofer. You will also need to   
					connect a second pair of RCA cables from the outputs on the back of   
					your subwoofer to the inputs on the back of your amplifier. When the   
					subwoofer is installed in this fashion, your satellite speakers will be   
					crossed over at 80 Hz which removes the lower bass frequencies from   
					your external amplifier and speakers, enabling them to do a better job   
					reproducing the higher frequencies. By utilizing this method, you will   
					have a bi-amplified system, gaining improved power and headroom for   
					your system. This installation method is not as common as the method   
					described in Figure 1. (Cables needed: 2 stereo pair of RCA cables.)

					Figure 3 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.

					SUBWOOFER OUTPUTS   
					TM   
					The Velodyne subwoofer is designed to operate using the full range   
					audio signal for input when using the built-in crossover. Many home   
					theater processors/receivers (Dolby Digital ®, DTS®, THX™) have a   
					“subwoofer out” jack that is internally filtered and designed to be used   
					with a powered subwoofer. In these installations, you may bypass the   
					internal crossover in either the processor or the Velodyne subwoofer. In   
					some installations, it may be beneficial to have a steeper ultimate   
					crossover slope. To do this, you can use both your processor’s   
					crossover and the one internal to the Velodyne sub. You should stagger   
					the frequencies, (i.e., 120 Hz sub, 80 Hz processor) for best results.

					When installing your new Velodyne subwoofer using the line level   
					connections, you should always use shielded phono cables. There are   
					many decent cables available today, most any of which will work   
					perfectly well. We do recommend that you keep the length of cable as

					When using speaker level connections, use a decent quality speaker   
					cable 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   
					damage your equipment. 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.

					CARE OF YOUR SUBWOOFER   
					TROUBLESHOOTING AND SERVICE   
					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.   
					If you should experience a problem with the operation of your subwoofer,   
					please check all of the following before seeking service. Following is a   
					simple troubleshooting guide to assist you.   
					1. Verify that the unit is plugged in, power outlet used is active and   
					supplying proper voltage.   
					2. Is the power switch on?   
					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.   
					3. Is the auto turn on/off set properly?   
					4. Is the unit receiving an input signal from your source?   
					5. Have all controls on the subwoofer (volume, crossover, phase,   
					etc.) been properly set?   
					6. If unit has been running at high levels for an extended period of   
					time, one of the protection circuits may be engaged.   
					• Is the built-in amplifier extremely hot to the touch?   
					• Is your power line voltage sagging below acceptable levels?   
					PROTECTION CIRCUITRY   
					Your new subwoofer is equipped with special protection circuitry to   
					provide maximum performance with greatest reliability.   
					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 unit is protected against:   
					1) Overdriving the speaker or amplifier   
					2) Overheating the amplifier   
					The following conditions require service by a qualified technician:   
					3) Excessive drop in power line voltage   
					1. The power cord has become damaged   
					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.   
					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 cabinet or circuitry is physically damaged
