Full Metal Chassis: The 351 A integrated amplifier features
an acoustically damped, low resonance full-metal chassis with a thick, brushed
45W x 2Ch Integrated Amp: Separate very high quality
integrated circuit amplifiers are used for each channel for freedom from
crosstalk and best possible stereo imaging. The Cambridge Audio Azur 351
A delivers an impressive 45 watts per channel into 8 ohms, at 20-20kHz,
with 0.15% THD at 80% rated power.
Torodial Transformer + Extruded Heatsink: At the heart of the
351A lies a heavyweight, audiophile-grade toroidal transformer, a premium component
chosen for its ability to offer huge power reserves, excellent bass response, depth
and rich musical reproduction across the volume range. The integrated amp also
offers a substantial extruded heatsink for excellent heat dissipation.
Polypropylene Capacitors: New low inductance resistors and
polypropylene signal capacitors are used for superior audio performance.
ALPS " Black Box" Volume Encoder: The 351 A integrated
amplifier uses a high end ALPS "Black Box: volume encoder that all of the signal
goes through this at all times, so this is a very key component. Benefits include
perfect channel balance at all volume levels and improved and stereo separation.
Protection Circuit: The 351A has full protection against misuse
and possible faults. The overload and short-circuit protection systems continuously
monitor the voltage, current, and temperature of the integrated amplifier's output
devices for safe operation.
Volume: Use the front-panel rotary volume control to increase
or decrease the level of the sound from the outputs of the amplifier. The volume
control affects the level of the loudspeaker output and the headphone output. It
does not affect the record output connections.
A/B Operation: The Cambridge Audio 351 A integrated amplifier
lets you play A speakers only, B speakers only, or A and B speakers together.
Direct: This control gives the audio signal a more direct path
to the power amplifier stage of your amplifier, bypassing the bass and treble control
circuits for the purest possible sound quality.
Bass and Treble: The 351 A integrated amplifier has independent
Bass (20Hz) and Treble (20kHz) controls which can be adjusted from +/-7.5dB. The
Bass and Treble controls only effect the speaker outputs; they do not effect the
Balance: This control allows you to adjust the relative output
levels of the left and right speaker channels. The Balance control only effects the
speaker outputs; it does not effect the record outputs.
IR Remote Control: The 351 A is supplied with an Azur Navigator
IR remote control that operates both this amplifier and Cambridge Audio Azur-series
CD players. The Azur 351 AC Navigator remote control can also control the basic
functions of Apple devices, such as Apple TV and Apple's iPod/iPhone/iPad when
docked in a Cambridge Audio or Apple dock (sold separately). The remote operates
off of three "AAA" batteries (supplied).
Analog Audio Inputs: The Cambridge Audio 351 A integrated
amplifier is fitted with five pair of gold-plated analog audio inputs (RCA) to
connect your external audio sources; such as your Blu-ray/DVD player, AM/FM tuner,
CD/SACD player, or Network Player. The 351 A integrated amp is not equipped
with digital inputs/outputs or video inputs/outputs. There is also no Phono
Front-Panel Aux Input: The Cambridge Audio 351 A integrated
amplifier features a front-panel Auxiliary (3.5mm) input to connect your portable
MP3 player or other portable audio device.
Record Outputs: The 351A integrated amplifier features a pair
of gold-plated analog audio record outputs (RCA) that can be connected to a CD
recorder, MiniDisc recorder, or tape recorder.
USB Port: The 351 A integrated amplifier is fitted with a
rear-panel USB (type-B) full-speed 1.1 port allowing USB audio streaming from
your Windows PC (XP, Vista, 7) or Mac computer (Mac OSX 10.5 or higher). The
USB port supports 16-bit/32kHz, 44.1kHz, or 48kHz audio.
A-B Speaker Terminals: The Cambridge Audio 351 A integrated
amplifier is equipped with two sets of gold-plated, binding-post speaker terminals
(labeled A and B). The use of A and B speaker terminals allow you to hook up
speakers in another room. When using two pairs of speaker, use only speakers
with a minimum nominal impedance of 8 ohms.
Headphone Output: The 351 A integrated amplifier offers a
front-panel 1/4" headphone output to connect a set of headphones for private
listening. When headphones are connected, the output to both A/B loudspeakers is
muted. Use headphones with an impedance of between 32 and 600 ohms.
AC Power Cord: The Cambridge Audio 351 A operates off of
standard household AC current using the supplied detachable 6' AC power cord.
Azur Series CD Player: The Cambridge Audio Azur 351 C Compact Disc Player
sold separately) is the perfect companion to the 351 A integrated amplifier.
DacMagic: Get even better sound from your computer's stored music
and Internet radio, as well as add optical/coaxial digital inputs to the 351 A integrated
amplifier, with a Cambridge Audio DacMagic external digital-to-analog converter
