US Blaster USB 1380 - Speaker Connections

Speaker Connections
This amplifier can operate in either one, two or three channel mode. The minimum impedance
for single channel (bridged/mono) operation is 4-8 ohms. There channel tri-power is referred
to stereo and mono at the same time. Minimum impedance remain the same for three channel
(satellite/ subwoofer) systems as long as proper passive crossovers are used.
Connect right and left speaker wire to corresponding speaker output terminals of the amplifier.
Be sure to have the positive wire from the speaker to the positive speaker terminal of the
amplifier and the negative wire from the speaker must connect with the negative speaker
terminal of the amplifier. Reversing any of these connections will result in the speaker cones
moving out of phase which causes bass cancellation. See Fig.5 Speaker Output Connections.
