These buttons enable the amplifier volume adjustment for suitable Cambridge Audio Azur range amplifiers. Note: If the 851C Digital Volume feature is enabled, the handset volume buttons will affect the signal output level from the 851C. Refer to section ‘Operating instructions’ for more information. Press to toggle between amplifier volume and balance control using the volume up and down buttons. Press to switch between the twin speaker outputs on Cambridge Audio Azur amplifiers with this facility. If the 851C Digital Volume feature is enabled, this button will mute/unmute the output of the 851C instead. Used to select sources on matching CA Azur amplifiers.

[. . . ] The Steep filter is able to attenuate aliasing at 22kHz by some 80dB for 44. 1kHz material for instance. Impulse response Amplitude 0 0 0 20 40 60 80 100 120 140 160 180 0 20 40 60 80 100 120 140 160 180 Time (samples) Amplitude Time (samples) Note: All filters exhibit the same ultimate roll-off of approximately 140dB. The following table shows the filter stop band attenuation for 44. 1kHz material: Linear Phase Roll-off at 20kHz Roll-off at 22kHz Ultimate roll-off -0. 1dB -10dB 140dB Minimum Phase -0. 1dB -10dB 140dB Steep -2dB -82dB 140dB We encourage you to experiment with the filters to determine which sound best to your ears and using your source equipment/programme material. The 851C remembers and recalls the selected filter type for each input individually, making it possible, for example, to select Steep for the USB input and Linear Phase for Digital Input 1, and so on. 13 Operating instructions cont. Custom installation (C. I. ) use The 851C incorporates a Control Bus input and output that enables unmodulated handset commands (positive logic, TTL level) to be received electrically by the unit and looped to another unit if desired. These control commands are typically generated by custom installation (multiroom) systems or remote IR receiver systems. [. . . ]
