GENERAL INFORMATION
The PPA V600 is a high-quality, two-channel preamplifier for moving-
coil and moving-magnet pickup systems.
Its groundbreaking design allows a variety of setting possibilities second
to none. Due to the implementation of professional instrumentation
amplifiers in the input section, it offers extraordinarily low noise figures
and extreme bandwidth even at high gain.
Features:
-
balanced inputs via gold-plated Neutrik 5-pin XLR sockets
- unbalanced inputs via gold-plated cinch sockets
- input impedance internally switchable, 9 settings
-
input capacitance internally switchable, 16 settings
-
low-noise instrumentation amplifier of extreme bandwidth
-
front-switchable gain, in six steps from +36 to +60 dB
- front-face balance c/- 2 dB
