Subwoofer Controls/Connections/Features Wi-Q User’s Manual

Low-Pass Crossover: Use this knob to select the frequency above which you wish to cut off the signal to

the subwoofer. When the knob is turned all the way to the left, the Subwoofer Direct feature is invoked and

the subwoofer plays all frequencies up to 135 Hz.

Low-pass Crossover - 40 to 135 Hz

The crossover control allows you to adjust the upper limit of the subwoofer’s frequency response

from 40 to 135 Hz. The subwoofer’s response begins rolling off above the frequency at which you

set this control. Set the crossover frequency to obtain a smooth and seamless transition from the

subwoofer to the main speakers in your system. The default crossover setting is 80 Hz. If your main

speakers are small with limited low frequency output, choose a higher frequency (such as 100 - 120

Hz). For larger speakers which have greater low frequency output, choose a lower number (such as

70 Hz).

Note: The subwoofer sums the left and right channels and passes the combined signal through

an adjustable low-pass crossover before sending it to the amplifier.

Subwoofer Direct

Use this setting on the low-pass crossover knob to allow frequencies up to 135 Hz into the

subwoofer. See the next section, Receiver/Processor Subwoofer Outputs for more about this feature.

Receiver/Processor Subwoofer Outputs

Your Velodyne subwoofer is designed to operate using the full-range audio signal for input when

using our built-in crossover. Many home theater processors/receivers (Dolby Digital™, DTS™,

THX™) have a “subwoofer out” jack (sometimes labeled “LFE”) that is internally filtered, settable at

the receiver/processor, and designed to be used with a powered subwoofer. In some installations, it

is beneficial to use BOTH the Velodyne crossover and the receiver/processor crossover, to achieve

a steeper crossover slope. In rare cases, combining an external crossover with the subwoofer’s

internal crossover may result in low output and increased noise. In these installations you may need

to bypass the crossover in either the processor or subwoofer, or simply set one crossover to a higher

frequency (such as 120 Hz) to restore maximum performance.

Alternate Connections

Your Wi-Q subwoofer uses modern 2.4 GHz wireless technology, so in most cases you can establish the

audio connection simply by connecting the transmitter to your audio receiver. In some situations, however,

you may need to connect RCA or speaker cables to your audio receiver. For these situations, your

subwoofer includes both line-level (RCA-type) and high-level (5-way binding post-type) connectors.

Note: Do not use both the RCA/Phono INPUT and SPEAKER LEVEL INPUT connections

simultaneously.

Line-Level Connections

Use the line-level jacks to connect your subwoofer to a pre-amp, a signal processor (with LFE out or

Sub-out), a line-level crossover, or a receiver with pre-amp level outputs. With line-level connections,

always use shielded phono cables, and to avoid potential noise problems, use the shortest cables

possible.
