HD112 - Impedance Selection
The HyDrive HD112 has an innovative dual voice coil design that allows the cabinet
to operate at either 4 or 8 ohms impedance. The cabinet has a impedance selector
switch on the rear jack plate.
If you are using a single speaker
cabinet, and the amplifier has a
minimum impedance of 4 ohms,
set the HyDrive HD112 impedance
selector switch to 4-ohms to get the
maximum power from the amp.
If you are using two HyDrive HD112
together in parallel, for a total
impedance of 4 ohms, or adding a
HyDrive HD112 to your current rig,
set the impedance selector switch to
8 ohms.
NOTE: Be sure to check the manufacturer's recommended minimum safe
impedance rating for your amplifier before setting the impedance selector switch to
avoid any damage to your amplifier.
