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-
