Connecting Your Amplifier
Connecting an Equalizer
Connect an equalizer or other external signal processor to the EQ IN and
EQ OUT jacks on the back of the amplifier.
Notes:
• You can also connect a tape deck to the EQ OUT jack for recording.
• The EQ IN/OUT jacks handle the signal from an outside equalizer. They
do not handle the signal from an outside equalizer’s stereo INPUT jacks.
Connecting Speakers
You can connect one or more 4-, 8-, or 16-Ohm speakers to the amplifier. To
ensure equal volume from each speaker, all connected speakers should have the
same impedance rating.
Proper phasing is important when you use more than one speaker in the same
room or area. Out-of-phase speakers can lose up to one-half of their potential
volume, and can have a significantly decreased bass effect.
Most speaker terminals are color-coded or have a mark that indicates the
terminal’s polarity. Usually, terminals with positive polarity are red or have a
plus symbol (+), and terminals with negative polarity are black or have a minus
symbol (–). Phasing is correct when you connect + to + and – to –.
You can also bridge the amplifier’s channels. The amplifier has two channels:
A and B. If you connect two pairs of speakers, follow these guidelines:
• Speakers connected to the same channel (A or B) are part of a pair and
must be of the same impedance.
• Speakers connected to different channels (A or B) are not part of a pair
and can be of different impedance.
