First time posting but long time user & fan of Audioholics which is a great reference tool. Gene & his team do a great job. I have a Pioneer SC-85 AVR running 5.2.4 atoms which has been running fine with no issues after 2 firmware updates.
The main problem is the amount of power provided by an external amp to Zone 2 which supports 4 pairs of 8 ohm speakers (PSB CS1000, PSB CS 500, BA Voyager 60 & BA Bravo). 2 external amps are connect to Zone 2 (Using Niles Amp cascade RCA connections to daisy chain the 2nd amp) External Amps Used: Niles SI-275 AMP (2 x 75 WPC@ 8 ohms), Emotiva XPA Gen3 -Two ( 2x 300 WPC @ 8 ohms);
Zone 2 has Multiple Outdoor Zones: Using a Dual Source, 4 Pair selector w/ volume control - Russound SDB 4.1.
Using a SPL meter I tested the db level of music playing at max level to the PSB CS1000 speakers (Zone 3) only using Emotiva XPA - 2 (Source A). All the other zones were off during this test to ensure all XPA power was directed to the active Zone 3 on the Russound. Results: SPL meter db avg. 80.0 , Peak 85.0.
I ran the same test again but connect the PSB CS 1000 speakers directly to Zone 2 terminals on the Pioneer SC-85 (135 WPC @8 ohms). Also, had to change the 5.2.4 AVR config in order to enable the Zone 2 terminals and used setup 5.1+Zone2+Zone3 for this test. Using SPL meter I tested the db level of music playing at max level to the PSB CS1000 speakers. Results: SPL Meter db Avg. 86.0 , Peak 95.0.
The SPL db meter differences between the 2 tests ranged between 5-10 db which can make big difference in overall performance.
Questions: Has anyone experienced these type of issues with db loss or power loss? Is the Russound SDB 4.1 a bottle neck? Is it normal or acceptable to expect this type of power loss with a heavy duty Russound switch?
I would appreciate and welcome any ideas, suggestions and recommendations that can help resolve this issue. After spending over $2000 for Emotiva XPA-2, Russound SDB, PSB Speakers and cabling I want to make sure it all works as expected......
Thanks.George
