Hybrid A1800MK6 Power Amplifier – 2 Channel with DSP

The Hybrid A-series power amplifiers have been serving the African audio professionals since the 1990s. Now, 25 years later, the MK6 A-series offers the same value and quality but with better output performance and features compared to its predecessors.

The Hybrid A1800 MK6 is a robust, 19″, 2U rack-space, 2 channel power amplifier with a comprehensive onboard, user accessible and editable DSP (Digital Signal Processor).
The A1800 DSP has all the features needed to maximize performance from your sound system, whilst protecting it at the same time.
Input and Output gain controls, Operation Mode, Electronic LPF & HPF crossovers with different filter types and slopes, 8 EQ’s with different filter types, Electronic Limiters, Time Alignment and Phase are all the features within the DSP that can be accessed by front-panel encoder controls or wirelessly (Wi-Fi Link) with any smaart device.

Inputs and signal link-thru are made using the panel mount XLR (Male and Female) connectors located on the rear panel of the amplifier. Similarly, speaker connections are made using the NL4 panel mount connectors. The A1800 MK6 can be used as a stereo, a parallel input or a mono bridged-mode amplifier.
