2.2.3
Single-ended mode
In
single-ended
mode, both channels of the zone are independent, and can drive up to 80 Watts peak power into
a nominal 4 ohm (minimum) loudspeaker. The mode switch must be set to the "SE" position, as illustrated in the
following diagram.
2.2.4
BTL mode
In BTL (bridge-tied load) mode, both channels in a zone are used to drive one loudspeaker. Combined, the two
channels in a zone can deliver up to 160 Watts peak power into a nominal loudspeaker load of 6 to 8 ohms

.
The mode switch must be set to the "BTL" position, as illustrated in the following diagram. The input signal is
connected to the odd-numbered input only. The output signal to the loudspeaker is taken from the "hot"
outputs of both amplification channels, as illustrated.

The PWR-16 is stable into a 4 ohm load when in BTL mode. However, an impedance this low places additional thermal
stress on the amplifier (in other words, it will heat up more quickly). We therefore recommend that a minimum 6 ohm load
be used for zones in BTL mode.
