Remarks

Other models of the same series: Sony STR-DE 445 slimmed down model: - only one optical digital input (2 times on the 545) - no additional switchable 220 Volt connection - no additional speaker output for front speakers - no S-Video connections - reduced output power via ELKO's (8000 micro Farad, instead of 10000 micro Farad + stronger power supply on the 545 with identical transistors) - simple remote control RM-U304 (Multi Function Remote Control RM-PP404 on the 545) The rest is identical!
