Introducing the first in Holton Audio’s commercial series of audio amplification products, this power amplifier uses the latest innovations not seen before in Holton Audio’s DIY products, but having all of the much sort after exceptional sound quality that Holton Audio products are known for around the world.
The chassis for this new amplifier is machined from 10mm high grade aluminium plates and all fastening of the plates are done from the inside of the case, allowing no visible or external mounting holes to show on the outside of the case. The top lid for the case is 10mm machined plexiglass, so you get to see the audio artwork inside the chassis.
The power plant for both channels is a custom designed 800VA encapsulated toroidal transformer which has 4 sets of secondary windings, 2 sets of windings are connected to each mono block amplifier module and each mono block module has a total of 56400f of supply filtering per channel.
Power management is handled by an analog computer AC mains controller, providing timed power turn on current limiting, sequenced audio output enable providing very clean audio output turn on and turn off. The new amplifier can be power on and off remotely via the 6.35mm jack 12 volt trigger input, the 12 volt trigger mode can be found on most higher quality per-amplifiers and AV receivers.
Power output with this model is 150 watt RMS into 8 Ohms and 260 Watts RMS into 4 ohms both channels driven.
This amplifier is due for release in September 2015, the price for this amplifier will be announced in July 2015.
