GROVER NOTTING® Power Plants

"The GROVER NOTTING® Power Plant is a uniquely musical and highly refined ‘all analogue’ critical listening power system designed to drive the GROVER NOTTING® Principal Audio Monitor range. The design technologies and techniques in this series represent decades of research by Australian Designer Hugh Dean. The power system is fully manufactured in Australia and presented in three configurations; the ultimate and optional drive system for the Universal Series, the drive for the Mastering Series and the drive for the LF Augmentation Series.

The key elements of the system include a very highly refined Class AB amplifier module, an active analogue transfer system incorporating High and Low Pass Filters, balanced line input circuitry, extensive system protection, Australian designed and manufactured Conrad heat sinks and a 2U rack mountable chassis system. The linear power supply is based around a very high capacity; bespoke toroidal transformer designed and manufactured by Sydney based Harbuch Electronics. Speaker outputs are heavy duty EP-4, four pin and inputs are three pin XLR rear mounted self-latching connectors.

UNIVERSAL Power Plant

The Universal Power Plant is specifically designed to drive all models in the GROVER NOTTING® Universal Series. However it will be equally well suited to drive any high performance speaker system. It is configured with two identical channels, balanced line input  circuitry, extensive system DC protection and a switchable high pass filter (in circuit for use with LF Augmentation).

MASTERING Power Plant

The Mastering Power Plant is designed to drive all models in the GROVER NOTTING® Mastering Series, offered as complete turnkey systems. It is configured as a mono block (one system per speaker enclosure) featuring a channel to drive above 100Hz and a higher output channel to drive below 100Hz. The system incorporates a 4th order, Linkwitz-Riley, 100Hz fixed point active analogue transfer system (high and low pass filters), balanced line circuitry and extensive system protection.

LF AUGMENTATION Power Plant

The LF Augmentation Power Plant is designed to drive all models in the GROVER NOTTING® LF Augmentation Series, offered as complete turnkey systems. It is configured as a mono block featuring a high output channel, balanced line circuitry, extensive system protection and a low pass filter.
