Œ Clipping Indicator: This yellow

LED indicates when the linkDQ’s

output reaches maximum signal

level before clipping (distortion)

occurs. It will be dimly lit just

before the onset of clipping, and

full bright at clipping. Since the linkDQ can produce up to 10Vrms,

its gain will usually be set well below this point while still

maximizing your ampliﬁer(s) input capability at minimum gain.

 Gain Adjustment: This adjustment is for matching the output of

the linkDQ with the maximum unclipped signal provided by your

source and the maximum input capability of your ampliﬁer(s).

Follow proper gain setting procedures to ensure optimum source

volume range without clipping at any point within the signal chain

while minimizing the ability to overdrive the system. Readjustment

may be necessary after any changes to other level or EQ settings.

Ž Parametric EQ: This section provides adjustments for a single

parametric EQ band with the tuning ﬂexibility required for

diﬀerences between vehicles, subwoofers and enclosures.

 Boost: Sets the amount of boost applied at the center

frequency (Fc), adjustable up to +12dB.

 Frequency: Sets the center frequency (Fc) of the EQ band,

adjustable from 30Hz to 80Hz.

‘ Width: This switch selects the width (Q) of the EQ band

between narrow and wide.

Note: Portable devices such as smartphones typically have an output voltage of

1Vrms or less. If using the device as the system’s volume control, it may be

necessary to adjust gain vs. volume range for consistent auto turn-on behavior.

For optimal signal range and convenient master volume control, the linkRC

remote level controller is recommended (sold separately).
