GENERAL INSTRUCTIONS
Input Capacitance Loading for MM Section:
Warranty Information:
Thank you for choosing a Bryston product. We
welcome any suggestions you may have, or
comments regarding the operation of your am-
plifier. We consider you, our customer, to be
Bryston’s most important resource, and your
opinion is very much appreciated.
Bryston products are warranted to be free from
manufacturing defects for a minimum of 20,
(twenty), years from the original date of manu-
facture. This includes all parts, labor and one-
way return shipping. This warranty covers the
original owner and any subsequent owners. The
warranty is retroactive for any Bryston product
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
authorized Bryston dealer or distributor. You
may also contact the Bryston factory or national
service offices directly at the location listed on
the rear page of this manual.
Please keep the original box and all packing
material. This will ensure the amplifier is pro-
tected in the unlikely event you have a problem
and must return it for service. No warranty card
is necessary to initiate your coverage. Please
refer to the back page for more detailed war-
ranty information.
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).
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
(See Figure 4, Page 4)
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.
