Peavey CS 800


The Peavey CS 800 amplifier has some of the best features that make it clearly stand out from the other amplifiers. They include;

  • Automated two-speed fan replenishing system
  • Autonomous fault safety
  • Temporarily accessible turn-on and off undertaking
  • One adjourned crossover socket for plug-in modules
  • Two recessed equalized intake transformer sockets for PL – 2’s
  • Solitary XLR and identical phone plug inputs even track
  • DDT activation LED and power LED for each track
  • Back panel DDT setback and bridge method select slip switches


The Peavey CS 800 power is 400W. It is outstanding as it is very durable in retail establishments and maintains the quality of execution required in office and household applications.


The Peavey CS 800 amplifier is considered a bit costly. However, purchasing the amplifier comes with a warranty of five years hence, assuring you of your money in case of any damage. Therefore, the extended warranty is surety for quality and value for money.

Parts List

For the Peavey CS 800 to roar in the market with its best features, it has essential parts that enable it to function and satisfy you. They include;

  • Front Panel

DDT ” Active LED – Illuminates when DDT” compression is taking place. With the setback switch in the setback position, the LED blinks when the clipping contortion happens.

  • Power LED

It brightens when AC power is to the amplifier is switched on and the related channel is functional. Due to the temporary suppression or thermal fault circuitry, brightness is halted negligibly during the power-up process.

If either channel encounters fault circumstances or surpasses the stable performing temperature thresholds, the track closes down, and the associated power LED goes out, implying such conditions prevail.

Also, whenever the bridge method is employed, the power LED on track B is vetoed (off), only as if there were erroneous conditions on channel B. This gives favorable evidence that the CS 800 is in bridge mode.

  • On/ Off switch / Pilot Lamp

The beginning panel of CS 800 has a conventional type On and Off switch with an internal pilot lamp.

When the Peavey CS 800 is clogged into a favorable power basis, initiating the button should light the pilot indicator lamp. Failure of the pilot lamp to come on may indicate the line fuse has blown or the power source is faulty.

  • Fan Speed Switch

The Fan speed switch determines the speed of the internal cooling fan, with the interior lamp indicating temperature shutdown conditions. For most applications, low-speed operations will provide adequate cooling.

However, high-speed operation is recommended for sustained high-power applications to avoid any shutdown of power due to overheating.

  • Mode Switch

It is found on the rear panel. The mode switch should typically be in the stereo position. Unless the amplifier is used in a retail sound dispersion system, you should not use the bridge mode in particular crossover applications. Unexpected shifting to the bridge method could destroy the speakers’ structure.

  • Patch Panel

The crossover patch panel of the Peavey CS 800 provides you with a very flexible system to facilitate balanced inputs and identical crossover webs. These characteristics are unattached in any different stereo-powered amplifier today.

  • DDT switch

This switch is used to facilitate the DDT constrictor or remove it.

  • Low Output Crossover

This tool replenishes the crossed-over low-frequency output from the PL-Module electronic crossover. To establish an operational bi-amp structure, you need to patch the output to the proper power amplifier intake jack.

  • High Output Crossover

This tool replenishes the crossed-over high-frequency result from the  PL-Module electronic crossover. To establish an operational bi-amp structure, one should patch the output to the proper power amplifier intake jack.

  • Clipping LED indicator

The clipping LED indicator with the compressor functioning occurs during amplifier output constriction. This happens mainly when the compressor is thwarted by taking out the level of control on the associated channel.

The LED indicator will light during every clipping situation, giving a solid warning to prevent severe contortion of the Peavey CS 800.

  • Fuse

The fuse is found within the lid of the fuse holder. If the fuse should cease to function, it must be repaired with the exact kind and quality to avoid damage to the device and deter revoking the guarantee. If the fuse keeps blowing, the device should be taken to a professional for repair.

The Peavey CS 80 manual is a document often given during the purchase. The manual indicates the working of the various parts of the Peavey CS 800.

It will help you identify and troubleshoot the amplifier even if it experiences problems after the warranty period. Thus, it is best to keep the manual safe and sound.

Please check out the Peavey CS 800 manual for more information.

Service Manual

The Peavey CS 800 service manual is usually a manual used to indicate the maintenance services to be offered to the amplifier. The service manual should alert you of the maintenance on the Peavey CS 800. It is permanently attached in the form of a document with the warranty document. Thus, it would help if you kept it safe as well.

Is The Peavey CS 800 S Any Good?

Many people still believe that CS 800 is a great amp. This is because it delivers a very clear treble and bass. Besides, the CS 800 has the same amp circuit as the original CS 800. So, yes, the Peavey CS 800 S are good amplifier.


The Peavey CS 800 is one of the most outstanding amplifiers today due to its features and best sound quality production. If you need to move outside the standard amplifier brackets and try a new innovation, Peavey CS 800 should always be your priority.
