Features
1 - XOVER IN / OUT:
Pressing this button engages a high-pass filter that allows a smooth transition between the subwoofer
and a full-range speaker connected to the output connector.
2 - POLARITY INVERT:
Allows you to set the polarity of the subwoofer to either Normal (no change) or Reverse (inverse
polarity). The correct polarity setting will produce the best blend between the subwoofer and the full-range speaker and
the strongest perceived bass response at the listening position. This is especially useful when the subwoofer is placed at
a different distance from the listening position than the full-range speakers. If the bass response seems weak, try
inverting the polarity.
3 - LEVEL:
Sound level adjustment. The 12 o’clock position is a good starting point for most usages. Once the full-range
system has been connected the level can be varied to match and deliver the desired balance (for details see Setting the
Gain on page 24).
6 - POWER SWITCH:
Turns the power on. Power “on” status is indicated with the illumination of the grille logo.
7 - LINE SELECT:
Allows user selection of different local voltage ratings.
8 - AC LINE INPUT:
Standard IEC AC line input connector.
Indicators
4 - SIGNAL:
Signal indicator. The green LED illuminates when a signal is present at the input connector.
5 - LIMITER:
The red LED illuminates when the system overload protection is active. If the input signal is too strong or the
“LEVEL” control set too high, the red LED will illuminate constantly. Illumination of the “LIMITER” LED can be avoided by
reducing the input level or turning down the “LEVEL” control to the point at which the red LED occasionally flickers.
Connectors
9 & 11 - XLR:
1/4 inch phone jack balanced input connector. (see Reference section page 29 for information).
10 & 12 - XLR:
Male balanced output connector. This connector provides a full-range or high-passed signal. Dependent on
the setting of the “XOVER” switch. In addition to connecting a full-range system to the output, it’s also possible to daisy
chain subwoofers together.
Note 3:
A single subwoofer can be used with a stereo source. The input differential circuits sum the low frequency information from the left
and right channel to a mono signal, ready for reproduction by the subwoofer.
