May want to add this to the FAQ, but it is also worthy of its own thread. When using the analog 5.1 outputs of the HD-A1, some users may experience a lack of bass compared to using the digital optical/coax output with their receiver. However, due to the possibility of enhanced quality using DD+, many prefer to use the analog 5.1 over the digital optical/coax output. This is due a 10db LFE output level difference when using builtin DVD decoders and certain receivers/preamps. If you have this issue of low LFE using analog 5.1s, follow the below steps: NOTE: Do not perform these steps unless you are having LFE issues! 1. Ensure levels are balanced with digital optical/coax output first (use THX optimizer for example to do this). 2. Enter Toshiba HD-A1 setup menu, click on Audio, click on 5.1 3. Ensure all speakers are set to Large/0ft, subwoofer is set to Use and crossover is set to 120hz. This will essentially bypass this portion of the decoder as most receivers will apply your receiver-set speaker volume levels/bass management globally across the digital and analog inputs. 4. Hit Next, now set the volume levels on the HD-A1 for left/center/right/left surround/right surround to -10db and subwoofer to 0db. Again, that is set all channels on the HD-A1 to -10db except subwoofer which should be set to 0db. This will effectively boost the LFE by 10db and rectify the LFE volume difference between analog/digital inputs for receivers that have this issue. 5. Exit setup menu and you are set! LFE level is where it should be. I used this procedure on the HD-A1 alongside my Parasound AVC-2500u to correct the bass discrepancy between the analog 5.1 inputs and the digital inputs, and it should work on any receiver where the 10db difference is found. Hopefully in a future firmware upgrade Toshiba will add a toggle option to boost the 5.1 analog LFE by 10db so the above setup procedure is not necessary.
