VP29 Phono Preamp
• Converts RIAA Phono signals
to Line Level
• Works well with magnetic
phono pickups
• Stereo RCA and 1/4" outputs
Phono players require special
equalization because of the fre-
quency response of recording on
vinyl. The VP29 equalizes and
amplifies the phono signal to a
clean, and full line level for profes-
sional amplification.
