Peavey CS4000 Power Amps Review

In addition to being able to provide mono amplification for instruments and vocals, the Peavey CS4000 is also able to output in stereo, making it suitable for house music and DJs. Peavey is known for pure, uncolored sound, and the CS4000 provides what musicians have come to expect: bass that pounds without sounding flabby, and highs that are crisp but never shrill. The Peavey CS series has been the workhorse of performing musicians for decades, and the sound quality of the CS4000 rivals that of many studio amplifiers.

While Peavey CS4000 Power Amplifiers are the ideal choice for a band or artist that plays very large or outdoor venues, musicians playing small to medium halls and clubs would be happier with the slightly lower powered CS3000, or with one of Peavey's many combo amplifiers, depending on the size of the venue.

With an amplifier that can produce more than 4000 watts of power, safety becomes a concern. For this reason, Peavey has outfitted the CS4000 with several safety measures. To prevent overheating under harsh stage conditions that can include bright lights or sun and little air conditioning, the CS4000 has internal heat sinks and variable speed fans. If a channel is ever in danger of overheating, it will automatically switch off, and that channel's fan will spin at full speed until normal operation can be restored. Meanwhile, the other channel will continue to operate. If there is ever an electrical issue that could damage the amplifier, it will detect the impending damage the shut off. Even more appealingly for concert situations, if the input volume going into the amplifier is too high, it will automatically limit the output to the speakers to prevent a blow out. When the volume is being limited, an LED on the front of the amplifier will switch on to warn the user. Finally, to prevent a loud pop, the amplifier will automatically mute output when the power button is switched off.

In its nearly 45 years of existence, Peavey has built a reputation for its amplifiers on three main selling points: clean sound, durability, and loudness. With its Peavey CS4000 Power Amplifiers, this standard of excellence has been raised to a new level. In bridged mono mode, the Peavey CS4000 is capable of a maximum output of 4000 watts. This puts the amplifier firmly into the territory of being the ideal hardware for very large or outdoor concert venues, where it can supply more than enough amplification power necessary to supply clear sound to the very back rows.

Peavey CS4000 Power Amplifiers - Summary:
* Rated for 4,000 watts of total power in bridged mono mode
* Suitable for very large or outdoor venues
* Able to output in mono for instruments and vocals, or stereo for DJs and house music
* Numerous protective measures to keep the equipment safe when heat or electrical conditions become dangerous
* Power output is very high and the volume level can easily overpower small to medium sized venues

Peavey CS3000 Power Amps Review

Peavey CS3000 Power Amp Since 1965, Peavey has been among the top names in the sound amplification business, and its Peavey CS3000 Power Amplifiers are no exception. They do one thing, and they do it extremely well: they play music, very loudly. The CS3000 has a rated bridged power of 3,050 watts, more than enough to provide sufficient volume for any small or medium-sized club or concert hall. It is a dual channel amplifier, suitable for instrument, vocal, or full-stereo amplification, making it equally worthwhile for DJs and bands. It also has a unique bridged monaural mode, in which the two channels are used together. This is powerful enough to create potentially lethal voltage, and must be used with extreme care.

The CS3000 delivers extremely accurate sound reproduction on similarly high-powered speakers, with punchy bass and crisp highs. It has the endurance to survive all-day music events, and harsh road conditions. Although this is certainly not recommended, there have been numerous reports of the CS3000 being dropped on hard surfaces, and surviving. Peavey backs the CS3000 with a five year warranty.

Due to the power of the CS3000, a number of safety features are included, which will be welcomed by musicians who are worried about overheating or speaker damage. One of these is called DDT, short for Distortion Detection Technique. This feature is present in an LED at the front of the amplifier. If the LED is solidly lit, the amplifier is actively limiting the master volume to prevent distortion from damaging the speakers. The amplifier also includes two internal fans and heat sinks, protecting the unit from overheating, and a variety of protective measures for electrical issues.

Although they are excellent in many performance scenarios, Peavey CS3000 Power Amps are not for every type of musician. Bands and DJs who perform in very large venues would do better to select an amplifier with higher power, such as the CS4000 or CS4080, and musicians who need an amplifier for rehearsals or small venues such as coffee shops will find that the CS3000 produces too much power. Musicians who play at small venues would be happier with a combo amp such as the Peavey Classic or Studio Special models.

Overall, the Peavey CS3000 Power Amplifier is an excellent choice for any musician who performs at medium-sized venues. The sound that it produces is crisp and accurate with tight bass response, and the loudness is more than sufficient for nearly any performance situation outside of the smallest coffee houses or largest arenas.

Peavey CS3000 Power Amplifiers Summary:
• Rated for 3,050 watts of total bridged power
• Powerful enough for clubs, small to medium concert halls, and some outdoor venues
• Can output in stereo for DJs or house music, mono for instrumentalists or vocalists, or high output bridged mono
• Runs cool in any normal performance environment
• Built-in protective circuitry keeps the unit safe from electrical overload and speakers safe from distortion
• Not an ideal choice for extremely small or large concert venues

Power Amplifer Classes – What do they Mean?

Anyone who attends a concert, let alone listens to music in any form or fashion, is aware of the power amplifiers have, although they are not as informed about power amplifier classes. Power amplifiers (sometimes known as amps) have the ability to heighten the signal a particular sound, which will include the bass, treble, etc.

It’s not unusual for a teenager to attend his first dance in middle school. Along with the excitement regarding the prospect of attending the dance, the student picks out a spot that allows him to scope out the room. He feels lucky to choose a spot close to the stage, but his excitement is short lived once he is aware of the power amplifiers have once the music kicks into gear. Unfortunately, it is a lesson that will not be forgotten, especially since the power amplifiers ring in his head until the morning hours. Little does the student know his introduction to power amplifiers will be so memorable.

Although knowledge of power amplifiers is familiar territory in the music arena, information of power amplifier classes may not be as recognizable. Power amplifier classes include A, AB, B, C, D, E, F, G and H. Power amplifier classes

Power amplifier classes A, AB, and B (linear)

Power amplifiers class A are the least efficient of amplifiers. This power amplifier class is likened to listening to in an increased form that is heard through the headphones of a simple portable CD player or mp3 player. This amplifier uses 100% input.

Power amplifier class AB operates between class A, which is linear, and class B, operates at a higher efficiency. It operates at 50% of the input without ever using the full 100% like power amplifier class A does. This equates to power amplifiers in class AB being capable when the transistor is on for more than a half cycle. However, it can also be lower than the full cycle of the signal.

Power amplifier class B concludes linear power amplifiers. This amplifier class has higher efficiency than either the A or AB class of amplifiers. Power amplifier classes B function at an inactive current. When comparing B class to the former classes, power amplifiers in the B class operate at an efficiency of 80 to 85%.

Power amplifier classes C and F (non-linear)
The uses of non-linear amplifiers establish that efficiency is critical.

Power amplifier class C is one that the output current remains at zero for more than 50% of the input signal cycle. A necessary part of the power amplifier class C is a tuned circuit.

Power amplifier class F will be the final classification we will discuss in this article. This non-linear amplifier classification is one with the highest efficiency. This power amplifier class has a current that is shaped to minimize their overlap.

Other High-Efficiency Classes include
D, E, G, H, and S
