Introduction

Your new Yorkville PX1700 power ampliﬁer is designed and built to provide years of trouble free performance. The PX170 0 combines ﬁeld proven reliability along with customer requested features such as switchable limiters, a Mono/Stereo/Bridge switch, SPEAKON™ output connectors as well as binding posts.

The PX17 0 0 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 PX17 0 0 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 unbalanced 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).

Remote Referencing

You can approach balanced performance with unbalanced sources by utilizing the remote reference feature of the PX170 0 . Connect a balanced cable to the PX170 0 just as you would if you were running a balanced line. At the other end, connect Pin 3 and Pin 1 together, (or connect ring to sleeve if you are using a PHONE plug cable), and plug this modiﬁed end into your unbalanced piece of equipment. This connection enables the PX170 0 ’s input to look down the cable directly at the output jack of the unbalanced equipment. Any hum voltage generated across the cable’s impedance will be attenuated by the common mode rejection of the PX1700.

Driving Multiple PX1700’s

In large installations it is often desirable to operate many ampliﬁers in tandem. Since each channel’s XLR input is internally paralleled with its phone input, you may use the remaining input jack as an output to the next ampliﬁer. Obviously you will need both XLR to XLR and PHONE to PHONE patch cords if you are going to tandem more than two ampliﬁers.

NOTE : These patch cords MUST be balanced whether the input signal is balanced or unbalanced!

Modes

Mono Mode

• Channel A & B inputs are paralleled

• Each gain control adjusts the signal level for its respective channel

• Output signals are of equal phase.

• Two loads are driven.

• Loads are connected between the BLACK and RED post on each channel.

Stereo Mode

• Two independent ampliers, Amp A and Amp B.

• Two loads are driven.

• Loads are connected between the BLACK and RED posts on each channel.

Bridge Mode

• Use channel A input and GAIN control. GAIN-B has no effect.

• Output signals are equal in amplitude but opposite in phase.

• One load is driven.

• The load is connected between the two RED binding posts. The BLACK posts are not used.

Limiter Switch

With the internal limiters activated, the PX170 0’s gain is continuously adjusted to ﬁt the signal within the available dynamic range. Occasional clipping is permitted. The limiters will not only help to protect your system’s horns and tweeters, but will automatically make the best use of the available dynamic headroom. With the limiters activated, all you need to do is turn up the signal level until you start to see some clipping. The limiters will make sure that you are getting the maximum clean power output at all times. Setting the switch to the OFF position completely disables both limiters.

Protect LED

In the event of a shorted load or a load which is of too low an impedance for the ampliﬁer to handle the PROTECT LED will turn on. In this case, the fault is in the speakers or the speaker cables and should be located and remedied. No reset of the PX1700 is required to restore proper operation. The PROTECT LED will stay on if the ampliﬁer has overheated. Check the speaker load impedance and any restrictions to air ﬂow at the air intake or exhaust vents of the ampliﬁer.

Short Circuit Protection

The PX1700 is fully protected against all possible passive load conditions. It can operate into a dead short continuously without damage. (However, we don’t recommend that you short your PX170 0 “just for fun.” Shorts do create a lot of stress on the output devices). The output stage uses a unique VI-limiting scheme which is sophisticated enough to remain inert during transient currents in excess of 40 Amperes and phase angles of more than 35 degrees, yet is capable of protecting the output stage from damage due to accidental short circuits and improper loads.

DC Protection

In the unlikely event of the PX1700’s outputs going DC, a protection circuit will disconnect the loudspeaker from the ampliﬁer.

Thermal Protection

In the unlikely event that the PX1700 overheats, the signal will be sporadically cut off and the PROTECT LED will stay on. The PX170 0 is designed and tested to operate under “worst case” conditions

without shutting down, so if you experience a thermal shut down you should check for blocked air ﬂow.

Cooling

The fan draws air in from the front and expels hot air through the rear vents. This is compatible with most installations. Since hot air rises, the heated air forcibly expelled from the back tends to rise away from the equipment rack. This draws cool air from the ﬂoor upwards into the front of the rack. In some cases where the rear of the rack is obstructed, it may be necessary to install rack fans to aid cooling. If there are no obstructions, no secondary cooling is required.

Clip LEDs

The CLIP LEDS on the front panel will visibly indicate any signal excursion beyond the dynamic headroom of the ampliﬁer.

Reliability

The design of the PX170 0 is conservative with respect to the power handling capabilities of the output devices. The topology guarantees that thermal stress not secondary breakdown will set the limits of operation, while the computer optimized heat dissipation system insures that excessive thermal stress will not occur. Yorkville’s reputation as a manufacturer of reliable equipment will be further enhanced by the PX1700.

WARNI NG: When driven to full power in Bridge Mode. There is more than 80Vrms appearing between the binding posts. This represents 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.
