General Information
With modern amplifiers expected to cater for so many new devices,
the Phono capability has frequently been one of the features to
disappear. Creek Audio has always been aware of the benefits of
vinyl – that is why the company continues to provide a number
of Phono stage options.
The OBH-15 Phono pre-amp can now drive longer cables, due to its
low output impedance. It has combined the high quality discrete
semiconductor circuitry of the OBH-8 and OBH-9 input and gain stages,
and added improved open loop gain by cascoding them, prior to the
selector switch and combined passive RIAA circuit. Separate Burr-Brown
professional grade low-noise op-amps are used for each channel,
to buffer the output signal and provide a very low impedance drive
to any pre-amp or integrated amplifier. The OBH-15 can switch from
moving magnet to moving coil cartridges, via a simple push button
on the rear panel. As it has two input circuits, optimised for each
type of cartridge it allows for the connection of two turntables.
A high gain MC version, for low output MC cartridges, is available
to order.
The OBH-15 has a built-in high performance power supply regulator
circuit which makes it immune from power supply fluctuations so,
it can be used with the un-regulated OBH-1, 6 Watt power supply;
but it will sound better with the regulated 12 Watt OBH-2, which
is available as an option.
Internally, the OBH-15 has built to the highest standards using
a glass-fibre double sided, plated through hole PCB and very high-grade
components. The OBH-15 looks the part too! Designed to complement
the Creek range of amplifiers, tuners and CD players, the new OBH
range features an impressive 4mm thick solid aluminium front panel
in a silver finish. The remainder of the 150mm deep extruded aluminium
case is painted black, so the product all but disappears. |
