HQ Video: Choose between RGB or YUV; if you have a YUV display, set this item to YUV, otherwise set it to RGB. Note that this setting has no effect on the HDMI output.
This setting controls the routing of the HQ-video within the AVR280, either as 3-wire YUV or 4- wire RGB signals (with the synchronisation signal on composite for RGB). In addition, it controls the operation of the S-video/composite-to-HQ video converter.
When set to YUV, incoming composite and S-video signals are converted to YUV; in RGB mode, the iincoming signals are converted to RGB, with the synchronisation signal on the composite output.
2 – Speaker Sizes
The size and number of loudspeakers are defined on this page.
Auto Set-up:Allows the setting of ‘standard configurations’ as in the table below:
Speaker | Config. 1 | Config. 2 | Config. 3 | Custom |
| | | | |
Front L/R | Small | Large | Large | Small/Large |
| | | | |
Centre | Small | Small | Small | Small/Large/None |
| | | | |
Surr L/R | Small | Small | Large | Small/Large/None |
| | | | |
Surr Back L/R | Small | Small | Small | Small/None |
| | | | |
Sub-woofer | Present | None | Present | Present/None |
| | | | |
5.1 Rears | Both | Both | Both | Surr L/R/ |
| | | | Sur Back L/R/ |
| | | | Both |
| | | | |
The Custom setting allows you to choose any combination of speakers to suit your system. Note that the centre and rear speakers cannot be set to ‘large’ if the front speakers are set to ‘small’.
5.1 Rears defines how the speakers in a full ‘7.1’ installation handle 5.1 decoded sources.
< Surr L/R redirects 5.1 surround signal to the surround left and right speakers. No signal will be directed to the surround back left or right speakers.
< Surr Back L/R redirects 5.1 surround signal to the surround back left and right speakers. No signal will be directed to the surround left or right speakers.
< Both redirects the 5.1 surround signal to both pairs of speakers with the signal to each set reduced by 3dB.
A note on speaker sizes:
A Large speaker is one that is capable of handling a full range signal (i.e., 20Hz–20kHz).
A Small speaker is one that is not capable of reproducing a deep bass signal (i.e., below 100Hz), for example a satellite speaker.
None indicates that there is no speaker connected to that channel.
3 – Subwoofer Settings
If no subwoofer was selected in the previous speaker menus then some of the items on
this page will not be adjustable.
Cross-over Freq.: This setting defines the frequency at which bass redirection begins.
Frequencies below this level are redirected from ‘small’ speakers to the Fronts or to the subwoofer; frequencies above this level are not redirected. The value for this
setting depends on your speakers, environment and taste, and is best determined by experimentation.
The adjustment can be made in increments of 10Hz between 40Hz and 130Hz.
Stereo Mode: Select between Large, Large+Sub or Sat+Sub.
If you have configured your system to have a subwoofer, then you have the flexibility to choose how bass information is distributed between the front left/right speakers and the subwoofer when listening to stereo sources. Choose the option which gives you the most solid even sounding bass (for best results test with a set-up disc or live program material).
< Large: Pure stereo information – all audio is sent to the front left and right speakers. Use this setting if you have large front speakers.
Note that this option will override the setting configured on the ‘Speaker Sizes’ menu page.
< Large+Sub: Pure stereo is fed to left and right and extracted bass is sent to the subwoofer. In
| this case the low frequency information is, effectively, duplicated. |
| < Sat+Sub: Use this setting if you have ‘Small’ satellite left and right speakers. Full bass |
| management is used in analogue stereo so that analogue sources are fed to the DSP where the |
| bass is filtered off left and right and redirected to the subwoofer. |
| Note that the above three Stereo Mode settings pass the audio through the DSP, which may degrade |
| the sound quality slightly. This can be avoided for the ‘Large’ setting by pressing the Direct button to |
| bypass the DSP processing. |
| DTS LFE Gain: DTS soundtracks typically have the LFE track recorded 10dB lower than the main audio |
| tracks. It is, therefore, necessary to compensate for this by raising the LFE output level by 10dB, and |
| setting the DTS LFE gain to ‘Normal’ activates this compensation. Some DTS soundtracks have been |
| recorded with the LFE signal at the same levels as the main audio, however, and therefore require no |
| gain compensation. For these disks set the DTS LFE gain to -10dB. |
| < Normal: This increases the LFE signal by 10dB and is the recommended setting for the AVR280. |
| < -10dB: This allows the LFE to pass directly to the output with no gain adjustment. |
| Unfortunately, there is no rule for determining which discs are recorded using which method. As a |
AVR280 | general guide, however, it is only early DTS music discs that require the -10dB setting. |
