The PX1700 has 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 a wire inserted into the side of the post..

All values are in WATTS. Measurements were made at the 0.1% distortion point. Some CONTINU-
OUS AVERAGE POWER measurements required line currents greater than 15 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 fac-
tors must be eliminated by using an ideal AC line. The BURST measurements use a 10mS burst at
1KHz with a 1/8 second pause between bursts. The 1KHz burst represents the maximum possible
sine wave output power.
CAUTION: The PX1700 can deliver over 1700 Watts of power into a bridged load.
Yorkville's own high power speaker systems have circuit-breaker protection built in.
Although these speakers will protect themselves, they are unlikely to be damaged by a
bridged PX1700 . However, many other speaker manufacturers make "high power cabi-
nets" with no protection features at all.
Yorkville Sound is not responsible for any damage which may result as a consequence of
exceeding such a speaker's power handling capability. Yorkville's Two Year Unconditional
Warranty does not cover any consequential damages to non-Yorkville equipment. Please
consider these facts carefully before you choose to run your PX1700 in Bridge Mode!
