Yorkville PX1700 - Manuel (Page 6)

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..
There are two Speakon™ connectors. The Speakons™ are connected to the amplifier’s out-
puts whether the amplifier is in stereo, mono, or bridge modes. Each Speakon™ output connector
(output A and output B) is wired in parallel with it’s respective binding posts for two channel two
cable connections (see figure 1, 2 and 3 on the following page).
Speakon™ output A also doubles as the A&B/Bridge connector. This Speakon™ contains
both channels on one connector. This is convenient when connecting one speaker to the amplifier in
bridge mode where the speaker is connected across the positives of each amplifier output. Config-
ure the
mode switch for bridge and connect the speaker 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 connect to the bridge/bi-
amp connector but use all four terminals in the Speakon connector which will connect A and B out-
puts separately to the speaker (figure 2). Connection configurations are labeled on the back panel.
Power Output
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!
