The gain control is NOT a volume control. The gain control adjusts the amount of signal required to drive the amplifier
to full output. With the gain at full clockwise rotation, less signal voltage is required to drive the amp to full output.
With the gain at full counter clockwise rotation, more signal voltage is required to drive the amp to full output. For
optimal performance, set the gain control to minimum.
High Pass Filter (HPF)
The high pass crossover/filter is designed to remove low frequency information from a speakers . This is generally used
to protect smaller devices from trying to reproduce low frequency information that might damage them. The crossover
frequency is adjustable from 50Hz to lkHz and uses 12dB per octave slope. To engage the HPF simply slide the switch
to the position on the marked HPF. Crossover frequency selection is made by rotating the dial: Clockwise raises the
frequency, counter clockwise lowers the frequency. Most mid-bass or midrange drivers should be set between 80 and
400 Hz depending on how high the subwoofer plays. For mid-range drivers that are 5" or smaller we suggest setting
the HPF to 120Hz. The HPF can also be combined with passive crossovers on a separate or coaxial speaker set to
provide low frequency protection to the midrange driver, or to form a band-pass filter for a midrange speaker already
using a passive low-pass filter.
low Pass Filter
The low pass crossover/filter is designed to remove high frequency information from a speaker. This is generally used
to prevent mid bass speakers or subwoofers from trying to reproduce mid and high frequency information that they
are not designed to reproduce. The crossover frequency is adjustable from 30Hz-250Hz and use a 12dB per octave
slope. To engage the LPF slide the switch to the position marked LPF. Frequency selection is made by rotating the dial:
Clockwise raises the frequency, counter clockwise lowers the frequency. Most subwoofers should be set between
80Hz and lOOHz depending on how low the mid-bass or midrange drivers are capable of playing.
Bass Boost
Bass boost is switchable to off [OdB] or +6dB and +12dB. Boost should be used with discretion. Electronically enhance
boost places an additional load on the amplifier and the speakers they are connected to.
