The VAC Phi™ 300.1 is an extremely potent amplifier with power, superb definition, and great control. Its eight beam power output tubes yield 300 watts in dedicated mono mode or 150 watts/channel in stereo mode at the choice of the user. Front panel level controls may be engaged to aid in balancing biamplified systems. Both balanced XLR and single-ended RCA inputs are provided. The chassis is machined aluminum, with the tubes beautifully showcased behind 0.75" glass. Also included are standard 12 volt triggers.
The Phi 300.1 is based on our direct coupled input & driver circuit that results in the fastest, fullest, most detailed sound that we have ever achieved. You will be surprised by details in your recordings that you had never heard before. The ambience and retrieval of reverb and decay information is particularly surprising.
Using eight beam power output tubes and a low-mu octal driver, this amplifier possesses an uncanny ability to reveal every nuance in a recording, while preserve the emotion and feel necessary for a truly musical performance. In addition to finesse, it has great power, impact, control, and a low electrical noise floor. This remarkable overall character makes it suitable for use with speakers ranging from high efficiency to the most difficult and demanding.
Both single-ended and balanced (fully balanced amplifier mode) inputs are provided. The chassis is custom machined 0.25" aluminum welded into a solid unitary structure, finished in metallic black paint. The 1" thick aluminum front panel is finished in hand rubbed silver metalic lacquer, with bias meter and tube adjustors that make it easy to maintain and optimize. Output matching taps are provided for 2, 4, and 8 ohm speakers.
