The Gryphon Antileon Revelation Mono splits the new power amplifier of the Antileon series into two chassis: a pair of pure Class A monoblocks , sold as a set, with 180 W into 8 Ω, 360 W into 4 Ω and 720 W into 2 Ω for each channel. No global negative feedback , no relay on the output and a chassis weighing 90 kg per side.
Compared to the stereo version, each channel has a dedicated power supply: 670.000 µF of capacitors per power amp, double the number of those dedicated to a channel in the stereo, and two toroidal transformers.dali per chassis, in shielded, epoxy-damped, and suspended cases. The final stage uses high-current Toshiba bipolar transistors; the output impedance drops to 0,02 Ω and the THD+N distortion remains below 1% up to 175 W into 8 Ω.
How do you connect two monoblock power amps to a Gryphon preamp? Each chassis has a 10 kΩ balanced XLR input and a pass-thru XLR; the Green Bias can also be routed from the preamp to the first power amp and from there to the second, so both change bias together according to the volume. The outputs are two pairs of parallel binding posts, suitable for bi-wiring , for bare wire, 4 mm banana plugs, and spades up to 17 mm.
The bias has three positions: High puts the full 180W into Class A, Mid puts the first 100W into Class A/B, and Low keeps the power amp cool. In High, each chassis draws 500W at idle and up to 2.700W at full power, with a single IEC C20 socket for a C19 cable. There's also soft start, a 12V trigger, microprocessor-controlled smart protection, and upgradeable software.
Each final guitar measures 57 x 26 x 60 cm, has a constrained layered damped frame, and comes with tips and under-tips. Electronic design by Tom Møller, line by Flemming E. Rasmussen, built in Denmark.
