Introduction
Your new Yorkville PX1700 power amplifier is designed and built to provide years of trouble free
performance. The PX1700 combines field proven reliability along with customer requested fea-
tures such as switchable limiters, a Mono/Stereo/Bridge switch, SPEAKON™ output connectors
as well as binding posts.
The PX1700 weighs a comfortable but solid 35 pounds, fits into two rack spaces, and repro-
duces music with over 1000 Watts of headroom. It will drive reactive phase shifted loads with no
difficulty – even though it is fully protected from accidental short circuits. Our design goal was
to create an amplifier which would do exactly what an amplifier should do: reproduce music with
great power, complete reliability, and uncompromising signal fidelity. We think you will agree that
the Yorkville PX1700 does exactly that.
Inputs

Balanced Inputs

Either XLR or two-circuit 'Ring, Tip, Sleeve' Stereo 1/4-inch PHONE cords may be used.
Each channel's XLR input is internally paralleled with its phone input (The TIP of the
channel 'A' PHONE input is connected to pin 2 of its XLR input, the RING is connected
to pin 3, and the Sleeve is connected to PIN 1). PIN 2 is in phase, PIN 3 is 180 degrees
out-of-phase, and PIN 1 is ground. We recommend using balanced lines for the best
hum -free performance, particularly when chaining multiple amplifiers.

Unbalanced Inputs

Ordinary single circuit Standard 1/4-inch PHONE plugs may be used to connect unbalanced signals.
IMPORTANT NOTE: Such plugs effectively connect the ring terminal to sleeve ground,
so they work correctly. However, if you use a Stereo 1/4-inch PHONE plug on an unbal-
anced line, you MUST short the Ring terminal to the sleeve terminal, otherwise the
sensitivity will be 6dB lower than is specified! (The same applies to the XLR input: To
connect an unbalanced source via the XLR input, you must connect the signal to Pin 2
and ground BOTH Pin 1 and Pin 3).
