The HyDrive HD Cabinets feature two
1/4” and two twist-and-lock connectors
wired in parallel. Each connector can
be used as an input from an amplifier
or as a pass through to an additional
speaker cabinet.
When connecting an HD series
cabinet to another extension cabinet
be sure to check the manufacturer’s
recommended impedance for the
amplifier to avoid any damage. Read
the section “About Impedance” for
more information on connecting
multiple speakers together.
NOTE: Never connect more than one amplifier to a HyDrive HD series enclosure. This
will damage the speaker cabinet and void the warranty.
NOTE: Use only unshielded speaker wire with a gauge of 12 – 18 AWG. Do not use
shielded instrument cables when connecting an amplifier to a speaker cabinet or when
connecting an extension cabinet.
Connecting the HD Cabinet
Using The High Frequency Level Control
The HyDrive HD cabinet has a control used to adjust the level of the high-frequency
driver. The switch has three positions, ON, -6dB and OFF. When the switch is set to
OFF, the high frequency driver is completely out of the circuit and off. Setting the
switch to –6dB, will attenuate the driver by 6dB. When set to ON, you get the full
level of the high-frequency driver.
