FEATURES
The Bryston BUC-1 is a state of the art USB digital-
to-digital converter with a USB input and three
different digital outputs; BNC, Co-axial & 3 pin
XLR(male). The BUC-1 supplies clocking signals to
the USB source device (e.g. personal computer) to
ensure a proper synchronized data stream
Features of the BUC-1:
• USB Audio Class 2 input (192KHz/24Bit asynchronous)
• USB drivers supplied on flash memory (thumb drive)
• Linear power supply
• Sample rates: 44.1KHz, 48KHz, 88.2KHz, 96KHz,
176.4KHz, 192KHz
• Transformer coupled SPDIF and AES/EBU Digital outputs.
• SPDIF Output (via CoAxial RCA/phono jack and BNC
connector)
• Remote On/Off Control Trigger input, 12 Volt
• Compatible with CD Drives, Sound Cards, Computers,
Music Servers.
• Cosmetically matches C-Series BP26, MPS2, etc
POWER CONSIDERATIONS
The BUC-1 has a three prong grounded IEC 60320
power inlet. Make sure that the voltage source you
plug an interconnecting line cord to is the same as
that stated on the "data plate" label.
Also, you can reduce the possibility of local ground
loops which could cause hum or noise in the system
by plugging its line cord into the same wall outlet
next to the power amp, pre-amp and other equip-
ment in your system.
Besides the front panel push-on/push-off power
switch, there is also a remote trigger (ON/OFF)
connector (a 2 conductor mini 3.5mm phone jack)
which when supplied with 12v @ 50mA or greater
will turn on the BUC-1).
A green LED located above the front panel power
switch will light when the unit is powered on.
INTERNAL FUSE
The BUC-1 contains a single fuse located inside the
unit. IF it should become necessary to replace this
fuse we recommend that you seek the assistance of
qualified service personnel.
To remove the top cover to access the internal fuse
a Torx-8 screwdriver is required. Remove all exter-
nal screws secruing the top cover and slide the top
cover towards the rear of the unit by approximately
1/4 inch before lifting it off the unit. After re-
placing the fuse, replace and secure the top cover
before reconnecting the power cord.
CAUTION: Whenever the BUC-1 is connected to a
power source hazardous live voltages are present in
the BUC-1. It is essential, therefore, before opening
up the BUC-1, that the power cord be disconnected
from it entirely. Replace a damaged or blown fuse
with the type and value indicated on PCB or the
fuse label on the PCB.
FRONT PANEL:
POWER SWITCH:
There are no switches or controls
on the BUC-1 besides the pushbutton power ON/
OFF switch. If the front panel LED power indicator
is on yet the power switch is in the out (Off) posi-
tion then the remote trigger is controlling the unit,
keeping it turned ON.
