Why do the pros choose Peavey power amps? Peavey provides the best value for money that can be found on the market. They manufacture a power amp that is suitable for any conceivable performance situation, and in every market segment, Peavey markets a power amp that produces better, louder sound than the competition, at a lower price. Peavey power amplifiers are known by their owners to maintain clean sound across their entire range of volume and dynamics. Where other manufacturers might attempt to produce sound that is "warm" or "colored", Peavey strives for the total accuracy that is preferred by most musicians with discerning ears.

Equally as important as sound quality, however, is the ability to continue operating properly under rigorous touring conditions. Peavey power amplifiers are all equipped with the same fault protection circuitry, ensuring uninterrupted operation even when problems arise. These features include:

• DDT (Distortion Detection Technique): automatically lowers internal gain when input volume is too high, preventing blown speakers or damaged internal components, and notifies the user that a volume adjustment is necessary via a front-mounted LED.

• Internal thermal protection: 1-2 variable speed fans combine with heat sinks to maintain proper levels of cooling even in the most sweltering performance environments. If a channel ever becomes overheated, that channel will temporarily shut down. The amp's other channel(s) will remain active, and the fan(s) will spin at maximum speed, until proper operating temperatures are restored.

• Electric overload protection: circuitry automatically detects severe power spikes or overloads, automatically disabling vulnerable components until the danger has passed.

• Automatic speaker muting: when the power is switched off or on, the speakers are automatically muted to prevent loud pops or thumps. This prevents speaker damage as well as possible damage to the ears of your audience if you are playing at a venue that is unable to maintain a reliable power supply.

The extensive fault tolerance of Peavey power amps has made them a mainstay in touring bands' shows for decades, with some musicians using the same power amp for over 20 years. That type of reliability is extremely difficult to find in today's electronics, with cheaper and cheaper components being utilized in an effort to reduce costs. Peavey, on the other hand, has maintained the highest standards in build quality for over 40 years.

The professionals choose Peavey power amplifiers because they represent the best quality available, at the most reasonable price. Peavey power amps are able to beat all other products in terms of reliability, build quality, and fault tolerance, all while maintaining the exacting standards for sound quality that today's performing musicians demand.

The Right Way to Bridge a Power Amplifier

Many power amplifiers rate their maximum power output in watts, when operating in bridged mode. When an amplifier is bridged, its two output channels are combined into one. Rather than driving two speakers, the amplifier then drives only one speaker. The benefit of bridging a power amplifier is that in bridged mode, an amplifier's maximum power output is almost always more than twice its maximum output in two channel operation. bridged mode can, in fact, bring a three- or four-fold increase in power. Four channel power amplifiers can also be bridged; when bridged, four output channels will become two.

When bridging a power amplifier, it is important to first reference the amplifier's instruction manual and confirm that it supports bridged operation. Although most power amplifiers do support bridged operation, attempting to bridge an amplifier that does not support it can permanently damage it. Also, the power amplifier's instruction manual will almost always have a diagram explaining how it should be bridged. Always be very sure of what you are doing before attempting to bridge a power amplifier, and if you are not sure, call the amplifier's manufacturer to confirm. Bridging a power amplifier can be physically hazardous, as many power amplifiers are able to produce currents that are potentially lethal.

It is vital to bear in mind that the primary purpose of bridging a power amplifier is not simply to make the sound louder, although that certainly can be a result. The purpose is to drive speakers that the amplifier would not ordinarily be able to properly drive. For example, some public address speaker enclosures containing several small speakers might ordinarily not be able to be driven by a power amplifier running in two channel mode, but may work in bridged mode.

Examining the rear side of a power amplifier, at least two sets of speaker terminals should be seen, each having one positive post and one negative post. To bridge the power amplifier, the two leads coming from the speaker should be connected to the positive post on one amplifier channel, and the negative post on the other channel. In the case of Peavey power amplifiers, this process is made simpler by the presence of red speaker terminals. To bridge the amplifier, simply connect the speaker to the two red terminals. Additionally, a switch on the back of the unit will need to be flipped in order to enable bridged operation.

Bridging a Power Amplifier:
1. Confirm that the power amplifier in use is capable of bridged operation.
2. Be absolutely sure of the method for bridging the power amplifier that is in use before beginning.
3. Use extreme care, as an amplifier in bridged mode is producing potentially hazardous currents.
4. Before bridging an amplifier to correct a volume issue, confirm that a different amplifier or speakers would not in fact be a better solution.
5. Bridge the amplifier by connecting the speaker to the positive speaker terminal on one channel, and the negative terminal on the other.

Peavey PV1500 Power Amps Review

Peavey PV1500 Power Amp The name Peavey is synonymous with high quality amplification. Since 1965, Peavey has been an industry leader in great sounding, low cost amplification, and Peavey PV1500 Power Amplifiers continue this longstanding tradition. The PV amplifier product range provides enough amplification power for small concert venues, while including many of the same protective capabilities found in Peavey's more expensive products. The PV1500 is rated for a maximum output power of 1000 watts, when operating in bridged monaural mode. In stereo mode, or when in normal dual channel monaural operation, the PV1500 sends 500 watts per channel to 4 ohm speakers, or 300 watts per channel to 8 ohm speakers.

Because it can be used to amplify either stereo or mono signals, the PV1500 is equally as useful for DJs as it is for instrumentalists and vocalists. Additionally, amplifiers from the PV series are very popular for front of house amplification. The PV1500 provides more than enough power for bars and clubs to use for their in house music when no performing artists are scheduled, or for educational applications such as school auditoriums. For bands, the PV1500 is sufficient to provide the amplification necessary for most small and medium sized concert venues, but may not deliver quite enough power for outdoor shows.

Peavey provides top of the line build quality throughout its entire product range, and the PV1500 is no exception. It is able to withstand the equipment abuse that is common in touring environments, and continue providing spectacular sound on demand. Many musicians have reported using the same Peavey power amplifier, with minimal repair work, for decades. The PV1500 includes Peavey's famous DDT (Distortion Detection Technique), which automatically limits input gain when clipped waveforms are detected. Clipped waveforms signify that the volume being sent to the amplifier is too high, and with no limiting, they can damage the amplifier's internal circuitry or any speakers that are connected. DDT effectively eliminates both of these concerns, and warns the owner with an LED that a volume correction needs to be made. The PV1500 also includes numerous built-in protective measures to keep the unit's internal heat down, and break the electronic circuits in the event of a severe power spike, stopping the flow of electricity before any damage can be done. In normal operation, the unit runs at an extremely low temperature for the amount of power that it produces, and as long as it is properly installed in an equipment rack as specified by Peavey, heat issues should never be a concern.

Peavey PV1500 Power Amplifiers - Summary:
* Produces up to 1000 watts in bridged operation, or 500 watts per channel in two channel operation
* Ruggedly built; able to withstand harsh road conditions
* Power level is sufficient for small and medium concert venues, but may not be ideal for large or outdoor venues
* Popular choice for DJ and front of house amplification
* Includes much of the same internal protective circuitry found in the more expensive Peavey product ranges
