hi, i have a yamaha sw215 subwoofer connected to a (uk spec) yamaha rx-v450, with speakers obviously but they arent relevant to my problem. ive read through the manual that comes with the subwoofer about making the unit automatically turn on when needed. i find that sometimes the sub doesnt always power on at the start of the movie. at the moment its set up as as follows.. on the rx-v450: all speakers = 'small' bass out = 'swfr' crossover freq = '80hz' (anything below this freq is sent to the subwoofer) swfr = '+5db' (everything else on 0db) on the sw215: high cut-off dial = '80hz' (anything above this freq is ignored) volume/gain dial set to '40%' (this shouldnt make a difference at all) i tested it by leaving the subwoofer in standby, powering up the dvd and avr and selecting 'play movie' as soon as i could. the times are from the moment i clicked on play movie to the time (according to the time display on the dvd) when the sub clicked on, sound levels for these tests stayed constant on both avr and swfr using the default sound track (dd 5.1): swat (r2) - 1:05 (during bank shootout when the guy fires his ak) black hawk down (r2) - 0:00 (during the dolby digital intro) rush hour 2 (r1 rce) - 0:00 (on the very first infinifilm intro before any other menus appeared) charlies angels 2 (r1 rce) - 0:27 (on the flame effect straight after the push-in past the columbia tristar lady) fast and the furious (r1) - 0:23 (as soon as the music started after universal logo had disappeared) the rock (r1 critereon) - 1:18 (when the words 'the rock' appeared onto the screen w/explosion) bad boys 2 (r4) - 1:02 (establishing shot of the 'smuggling coffins') matrix reloaded (r4) - 0:00 (dolby digital intro) any suggestions? other than 'get up and manually turn it on!' will be appreciated.. thanks.
