(9)SPEAKON® OUTPUTS

PV® amplifiers utilize three 4-conductor Speakon connectors, one for each channel and one for BRIDGE mode. Please refer to the BRIDGE MODE section of this manual before attempting to use this mode. For each channel Speakon, the same impedance rules apply as with the binding posts. Internally, all the Speakons are wired in what is called the “high current” mode, with pins 1+ and 2+ in parallel, and pins 1- and 2- in parallel. For the CHANNEL A and CHANNEL B Speakons, the respective channel output appears on pins 1+ and 2+. Pins 1- and 2- are chassis ground. For the BRIDGE Speakon, CHANNEL A appears on pins 1+ and 2+, and CHANNEL B appears on pins 1- and 2-. Always check the Speakon connector wiring carefully before using.

(10)MODE SWITCH

This switch is used to select STEREO or BRIDGE mode operation. It is a conventional push-push

type, requiring a small “tool” to activate. The IN position is BRIDGE mode; the OUT position is STEREO mode. Exercise care when selecting the BRIDGE mode. Accidental selection of this mode could damage loudspeakers, particularly in bi-amped systems. Amplifier BRIDGE mode theory will be covered later in this manual.

(11)DDT™ (DISTORTION DETECTION TECHNIQUE) SWITCH

This switch is used to enable or defeat the DDT compressor circuitry. It is also a conventional push- push type, requiring a small “tool” to activate. The IN position is DEFEAT; the OUT position is ENABLE. Normally, the DDT function should be enabled to minimize the possibility of either or both channels going into clipping or overload. With this feature defeated, a severe overload could cause the mains circuit breaker to trip. The Peavey DDT compression system will be covered in greater detail later in this manual.

(12)FAN GRILL

A two-speed DC fan supplies cool air to the amplifier. THIS INTAKE SHOULD NEVER BE BLOCKED! The fan switches to high speed automatically when the unit requires additional cooling. At idle and cool, the fan should be in low speed. The fan should never stop unless the amplifier is switched OFF or the AC mains power source is interrupted.

(13)INPUT BARRIER STRIP

A barrier strip is provided for input connections using bare wire or spade lug connections. PV amplifiers employ low-noise, electronically balanced input circuitry. This circuitry offers a very wide dynamic range capable of handling virtually any input signal level, while providing excellent common mode rejection to minimize hum and reduce interference. This strip accepts balanced and unbalanced audio signals. The "+" and "-" terminals are the positive and negative inputs to the respective channels. The GND terminal is the common ground to both channel inputs. For use with an unbalanced source, connect the "-" input terminal of the channel to ground with a jumper. If the "-" input is left floating, a 6 dB loss in channel gain will result and the floating input terminal may pick up outside noise.

(14)COMBO INPUT CONNECTOR

The combo connector offers both female XLR and 1/4" phone jack balanced inputs for each channel. The XLR is wired with pin 1 as ground, pin 2 positive input, and pin 3 negative input. The 1/4" phone jack is a tip/ring/sleeve (3-conductor) type, with the tip being positive input, the ring negative input, and the sleeve ground. It is important to realize that the XLR, 1/4" jack, and barrier strip inputs are all in parallel; therefore a balanced input to the associated channel can be accomplished using a male XLR, a 3-conductor phone jack, or bare wires connected to the barrier strip.

As an alternative, the 1/4" input can also be used with a regular tip/sleeve (2-conductor) type plug commonly found on single-conductor shielded patch cords. In this case, the input becomes unbalanced, with the tip as positive input, and the sleeve ground (the ring being grounded by the sleeve of the plug). An additional unique feature of this 1/4" input jack is something called a “quasi- balanced” input. The sleeve of this jack is connected to chassis ground through a relatively low-value resistance that is part of a ground loop elimination circuit. This circuitry will provide hum-free operation

PV Series specifications

Peavey is a well-known name in the music industry, particularly recognized for its range of audio equipment. Within its extensive portfolio, the PV Series stands out as a line of amplifiers and speakers that have earned a reputation for delivering high-quality sound performance and robust build quality. The PV Series is designed to cater to a variety of audio needs, making it an essential choice for musicians, sound engineers, and event organizers alike.

One of the main features of the PV Series is its impressive power handling capacity. The PV amplifiers are built to deliver high wattage output, ensuring that even in large venues, audio enthusiasts receive clear and powerful sound. This capability is complemented by the series' advanced speaker design, which includes high-efficiency drivers and reinforced construction. Whether for live performances, studio applications, or installation in permanent venues, the PV Series maintains clarity and fidelity at both low and high volumes.

Another defining characteristic of the PV Series is its versatility. The range includes powered and passive speakers designed to cater to a wide spectrum of sound reinforcement needs. The powered speakers offer built-in amplifiers, eliminating the need for external power sources, which simplifies setup and transportation. On the other hand, the passive speakers can be paired with various amplifiers to suit specific performance requirements.

Peavey’s unique technologies are also pivotal to the PV Series’ acclaim. The series benefits from proprietary innovations such as the DDT (Dynamic Drive Limiting) technology, which helps prevent distortion by monitoring signal levels in real-time. This ensures that users can push their equipment to the limit without risking damage to their speakers, providing peace of mind during critical performances.

Durability is a hallmark of the PV Series. The enclosures are made from high-quality materials designed to withstand the rigors of travel and use. Features such as reinforced corners, heavy-duty grills, and weather-resistant finishes make these products suitable for both indoor and outdoor use.

Finally, the PV Series offers an appealing price-to-performance ratio, making high-quality audio accessible to a wider range of users. Whether one is a seasoned professional or a budding enthusiast, the Peavey PV Series provides reliable and powerful audio solutions that stand the test of time. With a combination of power, versatility, and durability, it continues to be a preferred choice in various audio environments.
