FEATURES
Your rofono high-performance phono stage
GB
uses a series of shunt resistors to set your
cartridge impedance. The input resistance is factory
set to 47kOhms. To set an alternative impedance to
suit your cartridge, simply plug the supplied shunt
resistors into the RCA sockets marked 'Impedance'
on the left side of the back panel – this automatically
re-calibrates the rofono. This approach is far superior
to capacitance loading switches, which tend to be
cheap and affect the purity of the signal, in addition
to being an entrance point of RFI (Radio Frequency
Interference).
Between the 'Input' and 'Output' RCA sockets are the
settings for MM and MC. There are three options for
setting cartridge gain: left is MC:L low (50dB), right is
MC:H high (61dB) and centre is MM (41dB).
The power input socket is positioned to the far right
of the back panel and slightly to the left is the power
on/off switch.
