Get to know them!

Despite its diminutive form, Sweetwater studio engineers will be the first to tell you this Harrison Audio 500 Series Comp packs a punch! With its classic circuit design and top-quality components, the Comp more than “comp-ensates” for wild variances in a signal, easily reining loud sounds in and bringing quiet sounds up for a much more consistent sound. Use the Comp to level out drums, vocals, basses, and much more. Harrison Audio's Comp features all standard compressor controls, including Makeup Gain, Ratio, Release, Threshold, and a Gain Reduction meter with 2dB of gain reduction per LED light.

The gang’s all here

It might be a lunchbox unit, but the Harrison Audio Comp has all the controls you need for smooth vocals, leveled guitars, and slamming drums. From top to bottom: its Makeup knob is used for extra gain post-compressor. When you disable the compressor, this makeup gain also gets disabled, which is awesome because it allows you to quickly A/B the pre-/post-compressor signals at comparable volume levels. Next, the Release knob adjusts the speed at which the compressor will return to unity gain. Then, the Ratio knob increases the effect of the compression. Additionally, the Threshold knob sets the level that a signal must cross for the Comp to kick into action. Finally, the “IN” button enables or disables the unit.

Harrison Audio Comp 500 Series Compressor Features:

  • Renowned Harrison Audio sound in a 500 Series package
  • Classic analog circuit sound with top-quality components
  • All the necessary controls for subtle to face-melting compression — Makeup gain, Ratio, Release, Threshold
  • Makeup gain gets disabled when you disable the unit, which allows you to quickly A/B compressed and uncompressed signals
  • LED meter that indicates 2dB of gain reduction per light

The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
