Hafler SE240 - Manual (Page 7)

Conventional Stereo Connections
It is best to make all connections with the SE-240 switched
off. Each of the stereo speakers connects to one horizon-
tal pair of red and black outputs,
as identified left or right
on back of the SE-240. The input signals connect to the
corresponding input jacks, and the Mono/Stereo switch
should be set to Stereo.
Connections for Monophonic Operation
When you wish to drive a single loudspeaker with in-
creased power capability, the SE-240 can be operated in
a bridged mode which drives both channels with the same
signal and combines their output to deliver more than 350
watts into 8 ohms. In this arrangement, the speaker is
connected only to the two red output terminals. The left
red terminal is ‘+’, and the right red terminal is the ‘-’
connection. No
connections may be made to any black
terminal. Set the Mono/Stereo switch to Mono, and con-
nect the input signal to the left channel input only. Impor-
tant Note: Never use a speaker with an impedance of less
than 8 ohms when operating the SE-240 in the bridged
mode; the increased current output could damage the
amplifier.
LOUDSPEAKER SELECTION
AND PLACEMENT
Normal Stereo
The SE-240 is designed to deliver more than 120 watts of
audio power into an 8 ohm load. This will drive most
loudspeakers to a very loud volume level without clipping.
Note that speaker manufacturers often specify speaker
power requirements in two ways: nominal power (for
average volume levels), or maximum continuous power
(for momentary loud passages). Our 120 watt rating ap-
plies to maximum power levels. If your speaker im-
