INTRODUCTION
The Phi 300 is a unique power amplifier, and the most power and detailed in VAC’s history.
Featuring a new direct-coupled input & driver circuit, extremely fast and vivid sound is achieved
from both single-ended and balanced sources.
The Phi 300 may be used as a 150 watt/channel stereo amplifier, or as a 300 watt monophonic
amplifier, as determined by the rear panel switch. In either mode, front panel level controls may be
selected or bypassed; these can be useful in balancing room acoustics or trimming level balance
in biamp applications.
The front panel mute control is useful when exchanging cables or making changes to your system.
Triode switches are provided for those who wish to explore that operating mode.
The chassis is machined from thick aluminum, finished in a metallic base coat/clear coat finish.
The Phi 300 is designed not to the latest fad but to substance, for the highest possible sound
quality. Time spent familiarizing yourself with this manual will be well rewarded.
