Typical seTup
BRX enclosures feature four input/output jacks (two 1/4” and two Speakon)
wired in parallel. Connect the BRX INPUT to any audio amplifier capable of
4 ohm operation. Connect additional BRX enclosures from the EXT.SYSTEM
jack to the INPUT of the additional enclosure (be sure the amplifier is capable
of 2 ohm operation).
The BRX10.2, BRX10.4 and the BRX15.3 feature a HIGH FREQUENCY
ATTENUATION (dB) switch for accurately adjusting the high frequency level.
This is a positive lock switch preset at six levels of attenuation. A good
starting point for this switch would be in the -6dB position, or straight up 12
o’clock. As you turn the switch CCW the attenuation doubles to -12dB, then to
-24dB, and finally OFF turns the high frequency driver off. Switching CW the
attenuation halves to -3dB and then 0dB which turns the high frequency driver
full on.
