Overview:
The 651T is everything you could ever need from a hi-fi tuner
Featuring DAB+ technology, the Cambridge Audio AZUR 651T means you can not only enjoy regular DAB stations but also reap the benefits of new DAB+ digital broadcasts in even higher quality thanks to support for the latest HE-AAC audio format.
DAB+ is already available in Denmark and Australia with many other countries currently testing and trialling the system. In the meantime, countries which currently receive DAB broadcasts can continue to enjoy these on their 651T tuner.
The move to DAB+ can also enable far more stations to share the airwaves leading to greater choice.
- And whilst digital radio's convenience is indisputable, there's no escaping the quality of FM broadcasts. To this end, the 651T has a neat trick up its sleeve; completely separate analogue domain FM/AM tuners! FM sound quality is truly exceptional and separate DAB, FM and AM antenna connections ensure the optimal aerial can be used for each band.
- And in a period when you're thinking harder about the value of your purchases and genuinely considering the environmental impact of them, the 651T - like Azur amplifiers and CD players - benefits from Cambridge Audio's Energy Star approved eco-friendly standby circuit.
- This amazing design means the 651T consumes less than one watt in standby mode but critically... results in absolutely no sound degradation. So great news for your pocket and the environment too!
- In addition to these sonic and environmental benefits, the new Azur range has a completely fresh look. The 651T features a redesigned casework featuring a new high contrast reverse display, a thicker brushed aluminium front panel, a seamless wrap-over lid assembly and dual-layer damped feet, all of which contribute to better resonance control.
- The timeless aesthetic is an elegant evolution of the original Azur design and benefits from increased solidity and substantially improved ergonomics.

1.) AC Power Socket - Once all connections have been made, plug the AC power cable into an appropriate mains socket. Your 651T is now ready for use.
2.) Power On/Off - Switches the unit on and off.
3.) Control Bus - The Control Bus carries control information, in the form of demodulated remote control signals, between the tuner and other Cambridge Audio devices connected to it.
4.) RS232 - For custom install use.
5.) IR (Infra-Red) Emitter In - Allows modulated IR commands from multi-room systems or IR repeater systems to be received by the unit
6.) Line Output - Connect to your amplifier using good quality RCA/Phono cables
7.) Digital Outputs - Note: The Digital outputs only work in DAB mode.
- Toslink Optical Digital output – For output to a separate DAC or digital recording machine. Use a high quality Toslink fibre optic interconnect cable designed specifically for audio use.
- S/P DIF Co-axial Digital output – For output to a separate DAC or digital recording machine. To obtain best results, use a high quality 75 ohm digital RCA interconnect cable (not one designed for normal audio use)
8.) AM Loop Aerial - Connect each end of the single length antenna to the antenna terminals. Place the antenna as far from the main system as possible to prevent unwanted noise and to obtain optimum reception. If the AM loop aerial provided does not receive sufficient reception, it may be necessary to use an outdoor AM aerial
9.) FM Aerial - Connect an aerial to the FM 75 ohm socket (a simple wire aerial is supplied only for temporary use). Extend the lead and move the aerial
around until you get the best reception. For continued use, we strongly recommend using a 75 ohm outdoor FM aerial.
10.) DAB Aerial Input - Azur 651T has a 50 Ω F-type screw connection aerial for DAB signals (a temporary aerial is supplied).
