BT26
is a Turntable Phono / microphone preamp. If your current stereo receiver does
not have a input for a turntable this is your solution. It can also be used
with Dynamic or Condenser microphones as well. The BTECH BT26
is our best phono preamp, but is an amazingly inexpensive phono pre-amplifier that adds an
excellent phono capability to a line-level pre-amplifier, integrated amp,
or receiver. It provides full enjoyment of the sound retrieved from
records by a good turntable / moving-magnet cartridge combination. It performance
is embarrassingly close to that of units many times it price. The BT-26's
external power supply ensures that transformer hum and noise don't intrude
on the quality of the signal from a moving magnet cartridge. Instead of
using a plastic case as many more expensive outboard phono stages do, the
BT26 uses a heavy gauge steel box to house the electronics and avoid any RF contamination from outside influences such as radio stations and
computers. Apart from RF contamination, the steel housing also minimizes
external hum from nearby power amplifiers. The circuitry offers a gentle
infrasonic filter to minimize any rumble emanating from the turntable or
record itself. Extra on-board low-noise regulators
further contain any spurious hum. The combination of external power
supply, high-grade metal housing, low noise op-amp and other
close-tolerance components achieve a signal-to-noise ratio you would
normally expect only in costly amplifiers or receivers.
