Hi All
I had posed this question in a different forum but did not get an answer and hence the repitition. Some background: I have a Yamaha RX v-475 paired with Dali Zensor 7s, a Vokal centre and a Velodyne impact 12. I am perfectly happy with the system performance except for a minor irritation: the sub's auto standby feature. What this does is cut off the sub at lower volumes or when low/modertae quality music is being played. The solution to this was increasing the AVR sub channel gain all the way up to +7 on a scale of 10 and correspondingly decreasing the volume knob on the back of the subwoofer itself. Here are my questions/observations:
1. While increasing the sub channel gain to +7 in the AVR has solved the problem BY AND LARGE, the sub still cuts off sometimes at lower volume. I can further increase the sub channel all the way till 10 but would it lead to "signal clipping" as I have read?
2. One other suggested remedy was using a Y splitter for the single LFE subwoofer cable and plugging the subwoofer cable to both left and right LFE pins. Other (respected) forums have indicated that it is going to increase the sub signal gain by 6db and overall boost the sub output by up to 3db. I need a better understanding here of how the sub is coming out of standby. I thought voltage was measured in volts and what is the 6db increase being referred to here? Is it the strength of the output signal from AVR to subwoofer?
3. Assuming 2. above works (there are a lot of people who agree with this). Now because there is a 6db increase in the AVR's subwoofer signal strength, I would again reduce the sub channel gain in the AVR menu by say 2-3db to account for overall increase in sub output level as mentioned above. Will the signal strength from the AVR to sub still be higher than before and bring the sub out of standby at lower volumes and when lesser quality of music is being played now that both L and R of the sub LFE are being fed?
4. If clipping is not an issue at AVR sub channel level of +7, then I'd rather leave it at this level and use the Y splitter to simply increase signal gain to keep the sub on at lower volumes. I will correspondingly reduce the volume knob on the sub to account for any (perceived) increase in sub output/volume.
Any help or comments would be much appreciated,
Cheers
