”
The RB-PA2 is a dual stereo RIAA equalised
phono amplifier. This record player
preamp amplifies the small signal from
your pick up cartridge (either moving
magnet or high output moving coil
magnetic) and provides the necessary
RIAA equalisation required for vinyl
records, to match it to a line input of your
mixer, or amplifier. It uses a clean RIAA
response making it ideal for use with
broadcast turntables and DJ decks and
where vinyl records are being archived to
CD for high quality transfers, or for
converting albums to mp3.
It operates with phono cartridges with a
nominal output of 1mV to 25mV and has
been specifically tested to work with the
Technics SL-1200™ and 1210™ range of
turntables. Quality high specification
components have been used together with
low noise, fast acting operational amplifiers
to produce a superbly transparent signal
path. Additionally, the RB-PA2 runs without
a rumble filter to produce a powerful bass
response.
The RB-PA2 is a dual stereo unit to interface
up to two turntables. The inputs are phono
connectors with Neutrik XLR connectors for
the balanced outputs, which may be wired
unbalanced if required. Output gain is
individually adjustable for left and right
channels in the range 35dB to 65dB by
using pre-set potentiometers. Frequency
response is held within 0.5dB of the RIAA
curve and noise is typically better than
-84dB RMS A weighted at 40dB gain.
