Peavey PV2600 Power Amps Review

Posted on by

The PV2600 is able to accept stereo or mono inputs, making it suitable for use by DJs as well as bands, and due to its very high output capacity is able to fill medium to large concert halls with the clean, uncolored sound that Peavey users have loved for decades. The unit is also built to last. With its heavy metal construction and extensive circuitry for cooling and protection, the PV2600 is able to survive the high range of abuses that can occur with equipment that is used by touring acts.

Like the other products across the PV power amplifier range, the PV2600 utilizes DDT to protect both its internal components, and any attached speakers in the event of an input overload. DDT, otherwise known as Distortion Detection Technique, utilizes specialized circuitry in order to detect when sound is coming into the amplifier at too high a volume. An LED on the front of the unit lights up to notify the owner that a volume change needs to be made, and the PV2600’s internal volume is automatically lowered to prevent the speakers from being destroyed. The PV2600 also utilizes an internal cooling fan and heat sink to ensure that the unit will remain cool under hot stage lighting.

Legendary amplification company Peavey, founded in 1965, broke new ground with its introduction of the PV series of power amplifiers by including features normally included only in far more expensive equipment, in a package that was nearly as powerful, and far less expensive, than the flagship CS and GPS power amplifiers. Peavey PV2600 power amplifiers are the top product in the PV series, which also includes the PV900 and PV1500 amplifiers, along with the PV1600 and PV3800 bi-amp and tri-amp products. The PV2600 is able to output at a maximum of 1800 watts in bridged monaural mode, or in dual channel mode, at up to 900 watts using 4 ohm speakers or 550 watts at 8 ohms.

While the PV2600 provides excellent sound quality and amplification for medium and large venues, smaller locations could be easily overpowered by it. Bands that are still on the club circuit may be happier with the lower cost options in the PV amplifier range such as the PV900 or PV1500. Likewise, the PV2600 may not provide quite enough power for very large or outdoor concert venues. Bands that are performing in large venues would do well to consider the Peavey GPS3500, which has proven itself as the ideal amplifier for the largest concert halls.

Peavey PV2600 Power Amplifiers - Summary:
• Rated for up to 1800 watts of output power in bridged mono operation
• Heavy construction and numerous protective features ensure that equipment will not be damaged by issues with power or input levels
• Stereo and mono operation lend the versatility necessary for band members or for DJs
• Ideal for medium to large venues; bands playing in clubs or at very large outdoor venues might be better served by other Peavey Power Amplifiers

QSC RMX 2450 Power Amps Review

Posted on by

QSC RMX 2450 Power Amp When it comes to live sound, performing musicians demand two things: tonal accuracy and volume. QSC RMX 2450 Power Amplifiers are a low cost solution for professional stage amplification, providing top quality sound in a surprisingly small and affordable package. The QSC RMX 2450 is capable of operating in both monaural and stereo modes, making it suitable for use as a stage amplifier for instrumentalists, vocalists, DJs, or front of house systems.

The maximum rated power output of the RMX 2450 is 2400 watts when operating in bridged mono mode, or up to 1200 watts per channel when driving a pair of 2 ohm stereo speakers. It is equally capable of driving 4 and 8 ohm speakers, with an output of 750 and 500 watts, respectively. It provides a tonal response that is nearly flat across the entire frequency range, lending the accuracy that musicians demand out of their equipment. Some musicians may wish to use speakers that are unable to safely reproduce subsonic bass frequencies, however. For these musicians, the RMX 2450 features user selectable 30 Hz and 50 Hz bass roll-off filters. It has an independent roll-off filter for each channel, making it possible for the RMX 2450 to drive a main speaker on one channel, and a subwoofer on the other.

In addition to having some of the best sound quality available, the RMX 2450 is equipped with several safety features that help to ensure continued proper operation of the unit for many years. These safety features include automatic clipping detection, usually found on much more expensive amps. With clipping detection enabled, the RMX 2450 automatically senses when the input load is too high and may potentially cause a blown speaker, reducing the internal volume of the amp to prevent damage. This feature may also be disabled if desired. Along with clipping detection, the RMX 2450 has internal fault protection circuitry to prevent any components from being damaged by a sagging or spiking power supply. These features are combined with an internal heat sink and fan combo, designed to help the unit remain within the proper operating temperature range even under the harshest stage lights.

Any touring act would do well to have QSC RMX 2450 Power Amplifiers in its arsenal. The RMX 2450 is powerful enough to supply adequate volume for nearly any indoor concert venue, and many types of outdoor venues as well. Bands that are still playing in very small locations such as coffee houses, however, may be happier with an amplifier that supplies slightly lower power such as the QSC RMX 850.

QSC RMX 2450 Power Amplifiers - Summary:
* Rated for up to up to 2400 watts in bridged mode, or 1200 watts per channel in stereo operation
* Numerous fault protection mechanisms ensure proper operation under the most strenuous conditions
* User-selectable low frequency filters allow the owner to customize the amplifier's tone to their liking
* Three year manufacturer warranty, can be extended for an additional three years after purchase

Analog or Digital, Which Type Power Amp is Best?

Posted on by

When selecting a power amp, one must take several factors into consideration. A critical choice in making such a selection is whether to purchase digital or analog equipment. Each has its distinctive features, and knowing the benefits of each type will help you discern which type will best meet your needs.

Those who prefer analog power amps and other analog music equipment cite analog's classic sound and warm tone as its greatest benefit. Most analog equipment involves fairly simple circuitry and is usually easy to repair should you have a problem with the equipment. However, analog power amps can be slightly more expensive than their digital counterparts because their production is more intensive in terms of human labor. Additionally, under conditions of high temperature analog power amps tend to overheat and malfunction more than digital power amps. Unfortunately, because of economic constraints, replacement parts such as tubes and fuses for analog equipment that are no longer produced domestically must be imported from other countries, adding to the maintenance cost of analog equipment. Regardless of this however, many consumers choose analog power amps as part of a rig that gives forth a unique and flexible equalization range, and sounds great under any circumstances.

Digital technology in the field of power amps is a relative newcomer compared to analog power amp equipment. However, this is not a judgment against digital power amps. In fact, some would say that digital power amps are in many ways superior to analog equipment. For instance, while the circuitry of a digital (also referred to as "solid state") power amp is generally much more complex than that of an analog power amp, digital power amp circuit boards are generally cheaper, as they are produced domestically. This allows consumers to realize significant savings in long term repair and maintenance costs. Though fans of analog power amps argue that digital equipment cannot produce the same variety of unique tones as analog equipment, there have been great leaps in digital technology in recent years. Usually, digital power amps are fabricated in such a way as to allow a given unit to replicate any number of analog tones. While previous attempts at such emulation technology were found to be less than satisfactory for the seasoned audio professional, the technology has only gotten better. Thus, digital power amp equipment provides the user with a high-tech, low-cost means of meeting the audio needs of consumers.

In summary, both analog and digital technology have their comparative strength, weaknesses and unique qualities. Closely examining these differences, and even trying equipment before buying, will give you a wide range of equipment to select from when selecting the power amp that is appropriate to your needs.

Pyle PTA3000 Power Amps Review

Posted on by

Pyle PTA3000 Power Amp Pyle PTA3000 Power Amplifiers are likely to ensure that the quality of Pyle’s equipment does not remain a secret in pro audio for much longer, delivering up to 3000 watts of bridged muscle at a price that is sure to make the most stingy of audio engineers smile.

The PTA3000 is a dual channel power amplifier delivering a maximum of 3000 watts, with a 110/220 volt switching power supply. With the proper adapters, it can be made to work with virtually any power outlet in the world. In addition to the extra power, it also offers two features not found among the other amplifiers in the PTA series: a two way crossover switch, and a high pass filter. These two features will generally be used exclusively of one another; the crossover switch enables the unit to drive a subwoofer, whereas the high pass filter should be enabled whenever the unit is used to power standard speakers. With the high pass filter enabled, subsonic bass frequencies will be cut, protecting your speakers from damage due to low frequencies that they are unable to properly reproduce. Whichever application you choose, the PTA3000 will deliver the top quality sound that you would expect out of a much more expensive amplifier, with perfect reproduction of transient sounds, pounding bass, and crystal-clear treble.

The unit is also equipped with above average fault protection measures, including a status LED on the front that notifies the user if the input gain is set too high and in danger of causing clipped waveforms (and speaker damage), and electrical fault protection circuitry that automatically disengages the amplifier channels in the event of a power brownout or overload. Additionally, the unit is equipped with a variable speed cooling fan, which ensures that the PTA3000 will remain within the proper operating temperatures under the harshest of stage conditions, while also operating quietly enough to be used in recording studios or other installed sound applications.

Pyle PTA3000 Power Amplifiers are backed by a one year warranty, guaranteeing the unit to be free of defects in workmanship and not to suffer from equipment failure.

Although Pyle Audio is best known as a provider of top quality sound systems for cars and boats, they have recently extended their operations into the world of professional audio, quietly providing top quality amplification systems with some of the best watt per dollar ratios available today.

Pyle PTA3000 Power Amplifiers - Summary:
