Hum or Buzz, Distorted or Fuzzy Sound, Cleaning

Hum or Buzz

If the PR™15P is producing a hum or buzz, this can be AC outlet related. Try plugging the PR 15P into a different AC outlet. Sometimes, if a different circuit (breaker) is used for the mixer and the PR 15P, it can cause hum problems.

Ensure that shielded cables have been used to route the signal to the PR 15Ps inputs. If speaker cables with 1/4" plugs are used as an input cables instead of shielded cables, it will be prone to hum or buzz.

Hum may be ground loop related. Try lifting the ground connection at the speaker end of the signal cable if it is a balanced signal cable. Check any input changes carefully by first turning down the volume control, plugging and unplugging cables, or lifting the shield ground at the speaker end.

Check to make sure light dimmers are not on the same circuit as the PR 15P, the mixer or any source devices. If light dimmers are used, then it may be necessary to turn them full ON or full OFF to eliminate or reduce hum. This is a typical AC wiring/light dimmer interference problem, and not a design flaw of the PR 15P. The third wire (ground plug) on the AC plug should NEVER be removed or broken off.

Distorted or Fuzzy Sound

First, ensure the mixer (signal source) is not clipping or being overdriven. Make sure the volume control/s

(7) and (9) on the PR 15P have not been set too low.

Check that the input plugs are fully seated in the input jacks (5) and (8) on the rear panel of the PR 15P. Ensure that the proper MIC/LINE PAD setting is being used (6) for line-level signals, or that a power amp has not been plugged into one of the input jacks of the PR 15P.

If an extension cord is being used to provide the AC power to the unit, ensure that it is of sufficient current capacity and that it is not also being used to supply power to any other device.

The PR 15P has built-in EQ to extend and smooth the natural response of the speakers in the system. Bass boost and HF EQ have been applied and the system has a nominally flat response, so it should require little, if any, additional EQ. If excessive additional bass boost or HF boost have been added externally to the PR15P, it could cause premature overload at high SPL. Reduce the amount of any external (mixer, rack) EQ and see if that clears up the distortion.

Finally, realize that even though the PR 15P is a powerful and high output unit, it does ultimately have limits, and it may need additional powered units (or a subwoofer) to provide enough sound output or coverage. In this case, try turning the mixer levels down a little to see if that clears things up.

If, after checking all the things listed to check and anything else you can think of to check safely, and the system still exhibits problems, carefully note all conditions and check with your Peavey dealer for advice.

Care and Maintenance

Your PR 15P is a sturdy and durable product and will provide years of reliable use if properly cared for. Use common sense and read the safety warnings to avoid hazardous operating conditions.

The unit must be disconnected from the AC power source before any work is done on it. Refer all servicing to qualified service personnel.

Sunlight/Heat

Avoid prolonged exposure to direct sunlight, as this may cause the unit to overheat and thermally shut off. Excessively hot operating conditions can also cause a thermal shutdown.

Do not store in extremely hot or cold conditions or extremely high humidity. Always allow unit to come to room temperature before use.

Cleaning

Never clean the PR 15P while plugged in or turned ON! When the unit has been fully disconnected from AC power sources, use a dry cloth to remove soil or other dirt. Never use strong solvents on the PR 15P, as they could dameage the cabinet. Do not allow ANY fluids to drip inside the PR 15P.

PR 15P specifications

The Peavey PR 15P is a popular powered loudspeaker designed for musicians, DJs, and sound engineers seeking a versatile and robust solution for live sound applications. With its impressive audio performance and durable construction, the PR 15P stands out as a reliable choice for both professional and amateur use.

One of the key features of the PR 15P is its 15-inch heavy-duty woofer that provides deep, punchy bass response. Coupled with a 1-inch compression driver and a high-frequency horn, the speaker delivers clear and articulate high frequencies, ensuring a balanced sound across the entire frequency range. The combination of these components allows the PR 15P to produce a powerful output of up to 1000 watts peak power, making it suitable for large venues or outdoor events.

The PR 15P is equipped with a built-in class D amplifier, which not only provides efficient power but also contributes to a lightweight design. This amplification technology allows the speaker to deliver exceptional sound quality without the bulkiness often associated with traditional amplifiers. The enclosure is constructed from durable polypropylene, ensuring the speaker can withstand the rigors of transport and frequent use.

In terms of connectivity, the PR 15P offers versatile options that include XLR and 1/4-inch inputs, allowing users to connect a variety of audio sources such as mixers, microphones, or instruments. The presence of a built-in mixer with a 3-channel configuration adds to its functionality, making it an all-in-one solution for smaller setups. Additionally, a simple adjustable EQ allows users to tailor the sound according to their specific environment or preferences.

The design of the Peavey PR 15P also features a lightweight construction and ergonomically placed handles, which facilitate easy transport and setup. The speaker can be used in multiple configurations, including as a main PA speaker, a floor monitor, or even mounted on a standard speaker stand.

Overall, the Peavey PR 15P combines powerful performance, versatility, and portability, making it an ideal choice for a wide range of sound reinforcement applications. Its robust features and technologies ensure that users can achieve professional-grade sound quality, whether in a club, at a concert, or during a corporate event.
