OPERATION

ADJUSTING CROSSOVER FREQUENCY

The crossover frequency can be adjusted between 35-250Hz.The crossover is set to LP (Low Pass) operation only.

Turn the crossover adjustment knob all the way down.With the system playing, turn the crossover adjustment knob up slowly until the desired crossover point is achieved.

INFRASONIC FILTER

Placing the switch to "ON" engages a 28Hz infrasonic filter limiting the amount of low frequency information going to the woofer. Set this to your personal preference while listening to the system one way, then the other.

NOTE: We recommend using the infrasonic filter when using vented enclosures with this amplifier.

MODE SWITCH

Used to set the amplifier between single ,for single amplifier use, and Master or Slave for when connecting multiple bd amplifiers together.

The first amplifier in the series being set as Master and the subsequent amplifiers being set as Slave.This allows one gain, crossover, infrasonic filter and bass boost setting for all slaved amplifiers.

The gain on the subsequent (Slave) amplifiers can be used for fine-tuning.

A maximum of 100 bd amplifiers can be connected together using this method.

PHASE SWITCH

Used when bridging two bd amplifiers together using a bd Sync cable to phase one amplifier 180° from the other when driving a common load.

The bd Sync cable must be used to allow the two independent frequency carrier generators in each unit to be synchronized.
