TECHNICAL INFORMATION
GENERAL INFORMATION
The BT913 employs a special parallel and series switching circuit to protect the
amplier. Regardless of which loudspeakers are switched on, the amplier load
will not fall to less than half that of the loudspeaker in use i.e. if using 8 ohm
loudspeakers, the minimum load will be 4 ohms. Most ampliers will accept
a load of 4 ohms.
CONNECTION
The BT913 may be connected with 4mm Banana plugs (remove the plastic
safety inserts) or with bare ended loudspeaker cable. To use bare ended cable,
unscrew the terminals to reveal cable insert hole. To avoid short circuits, strip
speaker wire no more than 12mm (1/2”).
HEAD PHONE SOCKET
The headphone socket is parallel wired and does not mute the speakers when in use.
Speakers must be a minimum of 8 ohms
