  • Eight channels of compression
  • Full featured gates
  • Brick wall limiting
  • Link function


The ACP88 comprises eight channels of compression, brick wall limiting and seamless noise gating for a variety of applications. Each channel of the unit contains an audio compressor, which can also be setup as a limiter by varying the ratio of compression. The user has control over threshold, ratio, attack and release for each processor, in addition to selecting between auto or manual attack and release curves, and hard or soft knee compression types.

Additionally each channel of the ACP-88 has a separate dynamic noise gate, that can be used to gate an entire drum kit, clean up a noisy tape machine, isolate an instrument or separate a vocal from background noise. Each noise gate provides control over attack, threshold, release and gate close range. The gate close range can be useful in creating a more natural sounding blend or mix when gating many instruments at once.

Using the Link function allows the user to combine any combination of ACP-88 channels, effectively forming a sub-group. When linked, all processors follow the setting of the master processor, which is always the processor furthest to the left in a link group. For example, one could link together channels 7 and 8 to form a stereo pair, channels 3, 4 and 5 to form a subgroup of processors, while leaving channels 1, 2 and 6 available for independent applications such as compression, limiting, or gating as the situation dictates. In addition, every channel has separate bypass and gain controls.

A compressor sidechain jack is available on every channel. When multiple channels are linked together, the send of the master channel sidechain jack contains a mix of all the channels in the link, which allows control over multiple channels of processing with one sidechain send/return.

Australian Shipping Via DHL
DHL offers a great express shipping service to Australia from New Zealand. We are proud to be able to offer express shipping to main cities on the east coast of Australia, within the same timeframe ( If not quicker ) than local Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was overnight. However these services have been impacted greatly, and as such the overnight service has been suspended. Overnight shipping will likely resume once things have returned to normal.

Qualifying main centers include:

  • Brisbane
  • Sydney
  • Adelaide

Whilst this service is extremely efficient and will likely be delivered within 1-2 days 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it doesn’t arrive within the specified time frame, in most cases it will be delivered by the next day.

While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).

If you require urgent shipping and you don’t reside in one of the cities stated above, please contact us and we can find a solution that works best for you.

Please Note: Shipping via DHL is not available to PO boxes and/ or parcel boxes etc.
