way return shipping. This warranty covers the
original owner and any subsequent owners. The

purchased within the last twenty years. Tam-

pering by anyone other than factory authorized
personnel voids the warranty. Warranty service
may be obtained by returning the unit to any

Bryston BP1.5 Description:

The Bryston BP1.5 Phono Stage is a high qual-
ity broadcast grade Phono Stage offering both
Moving Magnet and Moving Coil cartridge step-
up capabilities.

The BP1.5 comes with an separate outboard
power supply to minimize noise and distortion.

The BP1.5 can be used without an additional
power supply if you currently own a Bryston
BP20 or BP25 Preamplifier. The outboard
power supply for the BP20/25 can be utilized to
power the BP1.5 as well with the supplied ca-
ble.

(See Figures 1 and 2 , Page 5)

Input Capacitance Loading for MM Section:

The Moving-magnet input capacitance switch is
located on the rear panel and consists of a four
element DIP (Dual In Line) switch and eight high
precision capacitors (4 capacitors for the left
and 4 capacitors for the right channel). This en-
sures the correct amount of capacitance across
the phono cartridge to provide accurate per-
formance.

Each switch adds in one capacitor (47 pf).

PLEASE REFER TO:

Switches 1 to 4 add capacitance to BOTH LEFT
and RIGHT inputs simultaneously . Any or all of
the DIP switches may be activated ( placed in
the upper position for On ) at one time or, in the
lower position (Off), meaning no capacitance is
placed across the phone inputs. As each ca-
pacitor is switched in the total capacitance in-
creases cumulatively Total value for each chan-
nel is 188 pf per channel
