Cyrus AV8

Use the ADJUST keys 3^ to change the input names on the bottom

row of the display until your preferred name appears from the list of

available names. The full list of names appears above.

Now you can choose to exit and save the changes (press the EXIT

key 3%) or to re-name another input (repeat step 1 to select another

input then step 2 to re-name it).

Setting speaker channel balance and positions

To ensure the best performance from your multi-channel audio system it

is essential to balance all sound channels to reproduce equal sound

levels from the system speakers. The AV8 includes two noise set-up

options-

•

Manual noise adjustment to balance individual speaker volume

levels.

•

Fully automatic adjustment to balance speaker volume levels and to

measure the distance to the speakers.

The automatic system is recommended, particularly for initial adjustment

to get the system running.

NOTE:- To allow high volume levels to be reached, high value positive

balance settings are reduced at very high settings of the volume control.

When this condition occurs, the display will flash the legend 'Balance

limiting' briefly. Normal balance settings are restored when the volume

setting is reduced.

Manual noise adjustment

Press the SET-UP 2 NOISE key 4) once to start the manual noise

sequence. MANUAL CAL will now show on the display and a 5 second

count down begins (Fig 4.3). After the count down a noise signal will be

heard from the front left speaker. Set the noise to a comfortable level with

the ADJUST keys 3^. The noise will now cycle around all of the system

speakers.

As the noise sequence moves you can compare the sound level from

each speaker and make level balance adjustments with the set up

ADJUST keys 3^. The display shows the active speaker and a bargraph

for balance level (Fig 4.5). If no adjustment is made within 2 seconds the

noise will sequence to the next speaker in the system. When adjustment

is complete, press the EXIT key 3%.

When noise adjustment is active the top row of the display will show the

selected speaker while the bottom row indicates the current balance

setting from –10dB to +10dB (Fig 4.5).

Manual distance setting

Before commencing manual distance setting, measure the distance from

each of the five main channel speakers to the listening position and make

a note of the measurements.

Press one of the SPEAKER HOT-KEYs 3& three times to select

speaker distance setting. The display will show the chosen speaker

name with the current set distance (Fig.4.6).

Choose a distance measurement for the chosen speaker from the

available options with the ADJUST keys 3^. Distances can be set in

the range 0-9.1m (30ft).

Press the next SPEAKER HOT-KEY to save this setting and move

on to set the distance to the next speaker.

Automatic level adjustment and distance setting

NOTE- For automatic setting the microphone must be connected to the

rear panel socket 1* before starting the process. The battery must be

fitted inside the microphone plug before use. Observe the polarity

markings when fitting the battery. Remove the battery from the

microphone if it is only used occasionally.

Before commencing the sequence, set up the microphone in the

listening position at approximately head height, facing vertically

upwards.

Press the SET-UP 2 NOISE key 4) twice to start the automatic

noise sequence. AUTO CAL will show on the display with a 5

second count down (Fig 4.7). Before commencing the AUTO CAL

sequence the AV8 will perform a microphone test with a short noise

burst. If there is a problem with the microphone or it's connection,

the display will show a 'Mic Error' indication. In this case the

microphone connection and battery should be checked before re-

starting the AUTO CAL process.

Following a successful microphone test the noise signal will be

heard at an increasing level from the front left speaker and the set-

up sequence will start.

The set-up sequence runs in two parts, the first will set the relative

volume levels between the loudspeakers, the second will measure the

distance from the listener to the speakers and set corresponding delay

times. At the end of the sequence the display will show 'Complete' (Fig.

4.8) for 5 seconds before returning to normal operation. The stored

settings can be checked, if required by selecting Manual Noise or

Distance adjustment.

Factory balance settings

The factory setting for all channels is centre scale when all channels are

at equal volume.

NOTE:- The noise sequence is also helpful to check that all channels

have been connected correctly. When correctly connected the noise

should start with the left front channel and circulate clockwise.

Setting up the sub-woofer

For correct reproduction of the deep bass content of multi-channel home-

theatre programs a sub-woofer is recommended for AV8 systems.

Deep bass information is fed to the sub-woofer in two ways-

From the separate LFE low frequency effects channel of digitally

encoded programs.

When one or more of the system speakers are set to 'small size' the

bass from these speakers will be re-directed to the sub-woofer.

Sub-woofer level

The overall level of sound from the sub-woofer can be adjusted at any

time by selecting SUB/LFE from the SPEAKER HOT-KEYs 3& and using

the ADJUST keys 3^ to increase or reduce the level from the sub-woofer

(Fig. 4.9). Most sub-woofers will also have a control panel which includes

level adjustment. The recommended procedure for setting the two

controls is as follows-

Set the AV8 sub-woofer level adjustment to 0dB (centre scale).

Play a program which includes sub-bass content and adjust the

sub-woofer level control to your preferred level.

A full ±10dB range is now available from this nominal setting via the AV8

remote control when listening.

Sub-woofer mode

The sub-woofer can be switched on or off at any time (for example, when

listening late at night) by pressing the SUB/LFE key from the SPEAKER

HOT-KEYs 3& twice and using the ADJUST keys 3^ to select ON or OFF

from the display (Fig. 4.10).

Sub-woofer crossover

The factory setting for the crossover frequency between small system

speakers and the sub-woofer is 100Hz which should be adequate for

most systems. If required, however the crossover frequency may be

changed to better match the low-frequency 3dB response specification of

'small' system speakers. The procedure for re-setting the crossover

frequency is as follows-

Press the SUB/LFE key from the SPEAKER HOT-KEYs 3& three

times. The display will show 'SUB X-OVER' and the frequency

currently set.

To change this frequency in the range 50Hz-150Hz, use the

ADJUST keys 3^.

Note:- If all system speakers are set to 'large', the sub-woofer crossover

frequency will have no effect.
