should be cleaned internally by a qualified service technician when
dust is visible on the heatsink fins. (see diagram, next page)
Note: In an unusually dusty location, without regular filter inspections,
removing the foam filter can extend the operating time before thermal
shutdown could occur. At that time, the internal heatsinks should be
cleaned thoroughly.

OUTPUT CONNECTIONS

WARNING: When driven to full power, there is more than
100Vrms appearing between the binding posts. This repre-
sents a significant shock hazard and due care should be taken
when making any speaker connections. Ensure that no strands
of bare conductor are exposed after inserting the speaker wire
into the hole in the side of the binding post terminals.
The A A P P 6 6 0 0 2 2 0 0 has 5–way binding posts and Neutrik four contact
SPEAKON™ connectors for output speaker connections. Connection to
the binding posts can either be made with a banana plug inserted into the
end of the post or by wires wrapped around the threads and tightened.
There are two SPEAKON™ connectors, one for each channel output.
All connectors are connected to the amplifier's outputs whether the
amplifier is in stereo or mono modes. Connection configurations are
labeled on the back panel. Each SPEAKON™ output connector (output
A and output B) are wired in parallel with it's respective binding post.
Speakon™ output A also doubles as the A&B/Bridge connector. This
Speakon™ contains both channels on one connector. This is conven-
ient when connecting one speaker to the amplifier in bridge mode
where the speaker is connected across the positives of each amplifier
output. Configure the mode switch for bridge and connect the speak-
er to pins +1 and +2 of the bridge/bi-amp Speakon (figure 3).
To connect a bi-amp speaker, configure the amplifier for stereo and con-
nect to the bridge/bi-amp connector but use all four terminals in the
Speakon connector which will connect A and B outputs separately to the

All values are in WATTS. Measurements were made at the 0.1% distortion point. Some CONTIN-
UOUS AVERAGE POWER measurements required line currents greater than 30 Amps. The amplifier
under test was plugged into an IDEAL POWER LINE consisting of a REGULATED 120 VAC RMS 60
Hz pure sine wave. Ordinary AC "wall outlet" lines will always exhibit varying and unpredictable
amounts of sag. To produce objectively verifiable and accurate specifications these unknown factors
must be eliminated by using an ideal AC line. When using an ordinary elecrtical outlet, it will usually
be possible to get 3600 Watts when the AP6020 drives 2 ohms. The BURST measurements use a
10ms burst at 1Khz with 1/8 second pause between bursts. The 1Khz burst represents the maximum
possible sine wave output power.
