The OBH-15 combines moving magnet and moving coil Phono pre-amplifiers,
into one diminutive chassis. Seriously impressive and offering
audiophile performance, the Creek OBH-15 will augment any system.
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 earlier model Creek phono pre-amplifiers 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.
