Arcam AVR250 manual Speaker Delay Settings, Distance measurements for 5.1 Speaker delay settings

Sub Stereo: This setting allows the volume level of the subwoofer to be adjusted for when the subwoofer is being used with 2-channel (stereo) sources. The subwoofer level for stereo music often needs to be set at a lower level than that for cinema use; use this trim setting, with a stereo source, to reduce the subwoofer output in stereo playback to an acceptable level. The level required depends on various factors such as speakers, the types and styles of music to be played and personal taste.

DVD-A Sub Level: This setting allows compensation for subwoofer level gain from external decoders or sources (such as DVD-A players).

When decoding digital inputs, the AVR250 follows the convention for products of this type and sets the subwoofer level 10dB higher than that of the other channels. Source products such as DVD-audio players do not follow this pattern, however, setting the subwoofer level to be the same as the other channels. This means that switching from material that has been decoded by the AVR250 to that decoded externally may mean that the subwoofer sounds very quiet. This setting provides for the removal of that difference by allowing the subwoofer level of the DVD-A (multi-channel) input to be raised by 10dB.

NORMAL: No gain compensation. This allows the DVD-A sub level to pass directly to the output with no gain adjustment.

+10DB: This increases the DVD-A (multi-channel input) sub level by 10dB

If you are using the AVR250 in combination with the multi-channel analogue outputs of an Arcam DVD-A player, then this item should be set to ‘+10dB’.

Distance measurements for 5.1 [and 7.1]

speaker delay settings

The speaker distance control can be

used to set automatically the appropriate time delays required for all the speakers in your system. To use this, measure from the usual listening position to the front of each individual speaker in the system and enter this value in the appropriate place. The measurements can be entered either in feet or metres, as selected from the ‘General Settings’ menu page.

An alternative to using the speaker distance control is to enter the delays manually in milliseconds.

Note that the delay adjustment is not a substitute for proper speaker placement, but can help to ensure accurate and correct signal arrival times from all the channels to the primary listening position.

No measurement can be entered for a speaker that is not selected in the previous ‘Speaker Sizes’ menu.

Note: Only enter these delay settings once you have specified which delay units (i.e., Time, Imperial or Metric) you will be using. The delay settings will be lost if the units are changed.

If the delay units are set to Time, then enter the delay in milliseconds for each channel.
