Ac Power Entry Connector; Usb Computer Interface Output - Benchmark ADC1 USB Instruction Manual

220. The fuse rating for all voltage settings is
0.50 Amps.
The AC input has a very wide input voltage
range and can operate over a frequency
range of 50 to 60 Hz. At 110, the ADC1 USB
will operate normally over a range of 90 to
140 VAC. At 220, the DAC1 USB will operate
normally over a range of 175 to 285 VAC.
Caution: Always install the correct fuses.
Always insure that the voltage setting is
correct for your locality.

9) AC Power Entry Connector

The AC power input uses a standard IEC type
connector. Within the USA and Canada, the
ADC1 USB ships with a power cord. In other
locations, a location-specific IEC style power
cord may be purchased from a local source
(including a local Benchmark dealer).
10) USB Computer Interface
Output
The USB input accepts a 'B-type' male USB
1.1 or USB 2.0 connector. An 'A-B type' USB
cable is provided with the ADC1 USB. The
USB cable connects the ADC1 USB directly to
a computer's USB output. The USB interface
utilizes USB 1.1 protocol, and is compatible
with both USB 1.1 and USB 2.0 ports.
The USB input supports 44.1, 48, 88.2 and 96
kHz sample rates at word lengths up to 24-
bits. The USB interface acts as a 'native' USB
audio device and does not require the
installation of any custom drivers.
Benchmark's Advanced USB Audio technology
achieves bit-transparent operation without
special drivers and without changing system
settings.
The Benchmark USB interface is truly a plug-
and-play solution. The ADC1 USB can begin
streaming high resolution audio bit-
transparently within seconds after being
plugged into a computer for the first time. No
software or hardware configuration is
required.
ADC1 USB Instruction Manual
The ADC1 USB is designed, tested and proven
compatible with the following four operating
systems:
• Windows Vista
• Windows XP
• Windows 2000
• Mac OS X *
* When using OS X the system sample rate
should be set to match the sample rate of the
files being played. Also, we do not
recommend using the OS X system volume
control – set it to 100%.
