Cyrus AV8

The Centre channel width setting varies the perceived width of centre

channel information from 0 (narrowest) to 7 (widest) by progressively

moving centre channel information into the front left and right speaker

channels. The Dimension setting adjusts the soundfield balance from 0

(balance towards the rear) to 6 (balance towards the front). The

Panorama setting, when switched on, additionally provides a 'wrap-

around' effect by mixing front channel information into the surround

channels.

The current settings will be memorised until next changed through the

menu system.

NOTE:- Centre width, Dimension and Panorama settings may not be

changed when set to Movie mode, 'Music only' will be displayed if these

menu options are selected.

Stereo

If a two-channel signal is detected the AV8 will automatically select Dolby

Pro Logic II decoding. If stereo reproduction is required (for CD music

etc) the STEREO key 3! of the remote control will switch between Pro

Logic II surround and Stereo decoding. An additional Stereo + Sub mode

is available via a second press of the STEREO key 3! which activates

Stereo decoding with bass reinforcement from the subwoofer (when

connected).

Press the STEREO key 3! again to return to surround decoding.

NOTE:- When purchasing program discs or tapes, check the legends on

the sleeve to ensure compatibility with the listed systems.

NOTE:- Some discs (e.g. DVD) may provide a selection of audio

encoding systems or a choice of languages. In this case the correct

system/language is selected from the control menu of the DVD player.

NOTE:- The AV8 employs an 'auto-mute' feature for DTS encoded

program material. If the DTS signal is interrupted (e.g. during fast search

or when changing discs) the display will read 'AUTO-MUTE' (Fig 4.16)

until the signal is restored. When changing from DTS programs to stereo,

it is necessary to re-set the auto-mute function with the MUTE key 3).

Level Control

The volume level is adjusted by the rotary LEVEL control on the front

panel 2^ or the LEVEL keys on the remote control 3$. When the volume is

adjusted the main display will switch briefly to show the setting in dBs

(Fig.4.15). Additionally, the display bargraph 2# shows the volume level at

all times.

Adjusting channel balance and Subwoofer level

The channel balance settings may be adjusted at any time from the

remote control with the SPEAKER HOT-KEYs 3&. Choose a speaker to

adjust with one of the keys then correct the channel balance with the

ADJUST keys 3^. The bottom row of the display will show the channel

balance setting in the range –10dB to +10dB (Fig. 4.5 shows centre

channel adjusted up by 2dB).

The Subwoofer level can be adjusted in the same way after first selecting

SUB/LFE from the SPEAKER HOT-KEYs 3&.
