5. GROUND LIFT / GROUND PUSHBUTTON

Whenever mixers, AC-powered signal sources, and amplifiers are interconnected, there is always the possibility of a ground-loop being created because something is not grounded the same as the rest, or because the other connected units are all ungrounded. Ground-loops result in a continuous 60-Hz hum which can be heard through the speakers. Normally, the PS210PX's ground reference would be grounded with the pushbutton in the GND position. If a hum occurs, try the switch in the GND LIFT position. If this does not help, restore it to the GND position and try reversing other grounds - perhaps anything electrical connected to the mixer. In the GND LIFT mode, the sleeves of the 1/4" inputs and pin 1 of the XLR are lifted from ground reference. In the GND mode, the grounding is done through a 10- Ohm protection device which prevents damage in case of accidental cable miswiring.

Note: When driving the PS210PX from a bridged source, set the GROUND SWITCH to GND LIFT!

6. LINE/SPEAKER PUSHBUTTON

This feature enables you to drive the PS210PX's inputs with either line-level or speaker-level signals. For example, if you have connected a mixer's MAIN (line-level) output to one of the PS210PX's inputs, you would push the button up into the LINE position. If, on the other hand, you have connected a parallel connection from another speaker being driven by a mixer/amp or power amp, into the PS210PX's input, you would push the button down into the SPEAKER position. It is important for this to be set correctly as to ensure proper performance of the product.

7. PARALLEL INPUT CONNECTORS

There are three inputs to the PS210PX power amplifiers, consisting of two 1/4" jacks and one 3-pin XLR-type connector. The two power amplifiers share these inputs. In other words, the signal coming into any one of the connectors goes to both amplifiers at the same time (i.e. there are no separate inputs to the amps). All three inputs are in parallel so that any one of them can be used to feed signal to another PS210PX or, if speaker- level signal is driving the inputs, to additional speaker enclosures. All inputs are balanced when the pushbutton is in the LINE position.

The 1/4" inputs are TRS (Tip-Ring-Sleeve) wired. Tip = 0° phase (positive) / Ring = 180° phase (reverse) / Sleeve = ground.

The XLR wiring is...

Pin 1 = ground.

Pin 2 = 0° phase (positive)

Pin 3 = 180° phase (reverse)

Note: see 5. GROUND LIFT/GROUND

Pushbutton regarding grounding.

Since the input impedance is very high (more than 17k-Ohms) any amplifier driving the PS210PX in parallel with speakers will not encounter a low load impedance situation.

8. THE POWER AMPLIFIERS

Both amplifiers are rated at 300 watts into 4- ohms and feature comprehensive protection from both thermal and input overloads.

Additionally, the amplifiers are regulated by full- time electronic limiting and automatic equalization (see 9. Internal Subwoofer LIMITER

&Automatic Equalization). The amplifier heatsink fins on the back panel should be kept well away from walls or anything which could restrict air flow around them. If the subwoofer amplifier overheats, its output power will be reduced by the limiter to compensate.

9. INTERNAL SUBWOOFER LIMITER & AUTOMATIC EQUALIZATION

In order to achieve maximum utilization of the subwoofer amplifier and subwoofers, the amplifier is regulated by a sonically transparent limiter and an automatic equalization circuit. Together, they respond to a variety of potential hazards including excessive heat, and clipping distortion in the amplifier; also, excessive speaker cone excursions or even speaker voicecoil overheating. Additionally, the EQ ensures extended deep bass down to 45Hz at low to moderate operating levels To protect the woofers at higher operating levels, the EQ's bass pre-emphasis is reduced as the limiter cuts in. At very high limiting levels, the EQ will actually cut the response below 60Hz to ensure that there will be no distortion or subwoofer cone damage. This still permits maximum clean sound pressure in the 90Hz range (for bass drum kicks).

Note: The PS210PX built-in stand mounting adapter can be used with Yorkville SW-Teletube

accessory to support our E160 cabinets. The support tube can be adusted up to it's full 5'4" extension

safely as long as the PS210PX is not inclined more than 10° (10 degrees).

WARNING: Larger or heavier cabinets should not be used!
