Introduction
The OneRemote RIAA DIN-II amplifier is designed for use with Bang & Olufsen turntables connected to
amplifiers without a built in RIAA amplifier, but it may be used with any turntable connected the same way.
When connected to a DataLink controlled Bang & Olufsen turntable any DataLink signal from a Bang &
Olufsen connected audiomaster is passed directly through allowing full remote control of the operation of
the turntable as specified by Bang & Olufsen for this set up.
The OneRemote RIAA DIN-II amplifier corrects the frequency response as described below and amplifies the
PU signal to line level.
The OneRemote RIAA DIN-II amplifier is supplied in a metal cabinet to maintain shielding of the signal, and it
is delivered with its own DC power supply.
RIAA
RIAA equalization is a specification for the recording and
playback of phonograph records, established by the
Recording Industry Association of America (RIAA). The
purposes of the equalization are to permit greater
recording times, to improve sound quality, and to reduce
the groove damage that would otherwise arise during
playback.
RIAA equalization is a form of pre-emphasis on recording and de-emphasis on playback. A recording is made
with the low frequencies reduced and the high frequencies boosted, and on playback the opposite occurs.
The net result is a flat frequency response, but with attenuation of high frequency noise such as hiss and
clicks that arises from the recording medium.
Reducing the low frequencies also limits the excursions the cutter needs to make when cutting a groove.
Groove width is thus reduced, allowing more grooves to fit into a given surface area, permitting longer
recording times. This also reduces physical stresses on the stylus which might otherwise cause distortion or
groove damage during playback.
The OneRemote RIAA DIN-II amplifier uses the exact same RIAA specifications as used by Bang & Olufsen.
