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, the preamp output,
and the headphone output. It does not affect the Rec Out 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 and preamp outputs; they do not
effect the record outputs.
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 and preamp 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
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 input.
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.
Analog Audio Outputs: The 651A integrated amplifier
features a pair of gold-plated analog audio 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)
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 (779351CB, sold separately) is the perfect companion to the 351
iPod Dock: A Cambridge Audio iPod dock makes a great add-on to the
A integrated amplifier (779ID50B,
779ID100B; sold separately).
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
integrated amplifier, with a Cambridge Audio DacMagic external digital-to-analog
converter (779DACMPLB; sold separately).
