Front IR

Mode

Volume

Used in conjunction with Custom Installation (C.I.) systems or IR repeater systems, it may be desirable to disable the front panel IR by setting FRONT IR to off (press the input select button to turn off). Press the Mode button to exit.

Input gain trim

The relative levels of the inputs can be adjusted by gain trim. This allows each to be adjusted so that each sounds the same in terms of average loudness when you switch between them. Pick the loudest sounding source and trim its level until it matches the average perceived level of the others. Repeat this process if other sources also stand out as louder than the average.

Mode

Volume

To set the input gain trim for each source, select INP TRIM in the System Configure menu. Select the input required and use the volume control to set the gain between 0 and -12 dB (the available range is restricted if the volume is set very low). Press the Mode button to exit.

C

Fixed level inputs

Any input of the 840E is able to be set for fixed gain. Whenever this input is selected the gain will automatically go to this value and will not be adjustable by the volume control. This can be useful with sources that have their own built in volume control (such as some set-top boxes etc.)

Also, this feature can be used to integrate an AV Receiver which has pre- amp outputs (such as our own 540R or 640R models) with the 840E.

The front Left and Right pre-amp outputs of the AV Receiver are simply fed to any desired input of the 840E and that input set for fixed gain. The AV receiver is then wired to the various surround speakers whilst the 840E/W drives the Front Left and Right.

The 840E/W can then be used for Stereo sources as normal for best sound quality. When it is desired to decode surround sound, select the input chosen for fixed gain on the 840E. Now the AV Receiver can be used to decode any of it’s surround sound sources. It will have control of the volume of all channels and the 840E’s own volume control will be disabled.

You may wish to re-name the fixed level input as “AV mode” or similar on the 840E. As the gain can be fixed to any value it is easy to match the level of the 840E to that of the other AV channels.

To set a fixed volume for a source, select FIXED INP in the System Configure menu:

Mode

Volume

Select the input required and set the fixed gain using the volume control (the OFF setting does not disable the input but leaves the input gain subject to the volume control which is the default setting). When a source has a fixed input, the balance is always set to neutral. Press the Mode button to exit.

Azur 840E specifications

The Cambridge Audio Azur 840E is a high-performance preamplifier that embodies the brand's commitment to delivering exceptional sound quality and innovative design. Known for its rich heritage in audio engineering, Cambridge Audio has built the 840E to cater to discerning audiophiles who seek a refined listening experience.

One of the standout features of the Azur 840E is its dual mono design. This architecture allows the audio signal to remain as pure as possible by using separate circuits for the left and right channels. This isolation minimizes crosstalk and enhances the overall clarity, ensuring a more immersive audio experience. The preamp's selection of high-quality components further contributes to its superior sound performance, allowing it to accurately reproduce music with depth and detail.

Integrating advanced technologies, the 840E includes Cambridge's proprietary 'ALPS Blue Velvet' volume control. This high-end potentiometer offers smooth and precise volume adjustments, eliminating channel imbalance and enhancing the precision of your sound. The preamp also features custom-designed capacitors and resistors, ensuring that only the best components are used to optimize sound quality.

Another noteworthy characteristic of the Azur 840E is its extensive connectivity options. It offers a comprehensive selection of inputs and outputs, including balanced XLR outputs, unbalanced RCA outputs, and a range of inputs for connecting various audio sources. This versatility makes it an ideal choice for audio enthusiasts who want to integrate the preamp into a more complex audio setup.

Moreover, the 840E also features a sophisticated remote control system, providing users convenience without compromising on performance. The intuitive layout allows for easy access to key functions, making it simple to tailor your listening experience.

In terms of build quality, the Cambridge Audio Azur 840E is designed with a robust metal chassis that reduces resonance and interference, further improving sound fidelity. Its sleek, modern aesthetics make it an attractive addition to any audio system.

In summary, the Cambridge Audio Azur 840E is a premium preamplifier that combines high-end audio performance with striking design and advanced features. Its dual mono architecture, superior volume control, extensive connectivity, and high-quality components make it a standout choice for audiophiles looking to elevate their audio experience.
