Phase Linear Pro Series Amplifiers


Phase Linear A15 Professional Series; Photo courtesy PhaseTek

 The A15 was Phase Linear's answer to the Crown D60 with a little more power and a built in limiter to protect high frequency drivers from clipping damage. Not many were built in 1982 before Phase Linear closed its doors in Washington. It featured 65 watts channel stereo or 190 watts mono.

The A15 was an amazing feat of electronic component packaging to meet minimum rack mounting space requirements.  It reflected the latest technology available in the early 1980s and this rarely seen component still sounds great today.



Phase Linear A30 Professional Series

The A30, introduced in 1980, was part of Phase Linear's Professional Series of power amplifiers and was assembled in Lynnwood. Like the other amps in the Professional line, it was primarily sold through dealers offering equipment to professional musicians. It was designed for rack mounting.




Phase Linear A60 Professional Series

The A60 was the next step up for the professional musician and boasted 225 watts per channel. Like the A30 it was entirely black.  It was a 19-inch rack mount design. It was taller than the A30, having a considerably larger power supply, but essentially the same controls.


Pro 700

Phase Linear 700 Professional Series 

The PRO 700 was introduced by Phase Linear in 1982. Electronically is was nearly identical to the 700 most were familiar with, differing primarily in its aesthetics. It was designed for professional use in recording studios and live performance duties by musicians. It featured a black anodized front panel and rack handles. Examples are very rare today because most Pro 700s saw hard use.
