Operating instructions

The 851E has a custom-made display on the front of the unit that shows

the current status and allows you to access the 851E System settings

menu. Here you can adjust the listening settings of the amplier to

personal preference. The menu system is easy to navigate and control,

simply by using the input select buttons to turn a feature on (solid circle)

or off (no circle) and the volume control knob to increase/decrease

settings.

Volume

Mode

Volume

Adjust the volume control knob on the front panel (or using the remote

control). The display will show the change in volume in decibels (dB).

'OdB' indicates maximum volume while lower volume settings progress

into the negative range. This can also be changed to arbitrary volume

units (0-90) in the System settings menu.

Balance

Mode

Volume

Press the Mode button to enter Balance mode. 'Balance' will appear on

the display and can be adjusted using the volume control. Press the

Mode button again to return to Volume mode or wait 5 seconds for the

851E to automatically exit Balance mode.

Bass and Treble

These controls allow subtle adjustments to the tonal balance of the

sound. Modify the sound through your loudspeakers and the Pre-Out

sockets only; they do not affect the signals sent through the Rec Out

connections. With a well produced CD and a good system the tone

controls are unnecessary and can be bypassed by pressing the Direct

button:

Source 3

Source 4

Source 5

Source 6

Source 7

Rec In

Direct

This completely removes them from the signal path for maximum delity.

If the musical recording is of poor quality or other factors are affecting the

sound quality, if desired you can adjust the tone controls to compensate.

To use the tone controls press the Direct button so that the Bass/Treble

icon (

t) lights in the display indicating that they are active and direct

mode is Off. Now press the Bass or Treble control button to release them

and allow adjustment; push them back in when nished:

The 851E stores whether direct mode is on or off for each input

individually, for example it is possible to have the tone controls

automatically active for the Tuner source but not the CD source.

Pre-amplier setup

The 851E features many advanced settings that allow its use to be

customised to user preference. The inputs can be named to reect the

actual source units you have, each input can be trimmed so that each

sounds the same in terms of loudness when you switch between them

and other options.

The 851E features a Sub output that is a separate mono mix created

from the main pre-amp outputs. This output can have either a 'Flat' (i.e.

full range, unltered) frequency response or a 200Hz Low Pass lter can

be applied. See frequency response graph below.

Full range

200Hz Frequency

Most Subwoofers feature built in Low Pass ltering and 'Flat' is usually

the best setting. This setting does not affect the main outputs which are

always full-range.

To select the 200Hz LPF, press the Sub LPF input select button in the

System settings menu. Press again to revert to the full range frequency

response. Press the Mode button to exit the System settings menu.
