The modules use my proprietary dual feedback modulator. The modules are fully balanced from input to output using bridged GaN power stages.
Only high-quality components from TI, Analog Devices, Panasonic, Sagami, etc.
150W BOSC GaN Module Specifications:
Full test results using APX525 posted here (scroll down):
Orchard Audio - Audio Power Amplifier, Home Audio, Home Stereo System | Orchard Audio
Required Power Supply:
48V, 250W for 100W output into 8ohm
54-56V, 250W for 150W output 8ohm
Mating Power Plug: Molex / 39-01-2060
I have multiple customers using these:
Murata / PQC250-54
The modules are capable of 300Wrms (600Wpeak) into 4 ohms but will require heatsinking of the GaN power stages.
MSRP for 2 modules $700, discounts as follows:
