A. Manual Speaker Setup allows the user to designate the number, size, distance, and sound levels for all the speakers. If you use the MCACC setup option, you do not have access this menu unless you wish to make further manual adjustments.
B. Input Setup allows the user to specific what you have connected to the digital, HDMI, and component inputs.
C. OSD Language sets what language to display on your TV screen for navigating the rest of the menus.
D. Network Setup provides the steps needed to connect the VSX-1020 to the internet.
E. Other Setup provides access to additional settings for power-on volume level (the volume level you want when you turn the receiver on) and volume limitation (the maximum volume setting you want - prevents you or others from accidentally setting the volume too high), Remote Control Mode, and Flicker Reduction.
The VSX-1020-K offers convenient and abundant features on the digital side. Two of my favorite features are the front mounted HDMI and USB ports. However, on the analog side, the lack of 5.1/7.1 channel analog inputs and outputs is disappointing.
This is one of the least expensive receivers to offer 1080p video upscaling, but I found this aspect of the 1020-K's performance in this area to be somewhat diappointing, just as it was with its predecessor, the VSX-1019-AH-K It would have been nice to see some improvement in this area.
As an added note, although the VSX-1020-K is HDMI 1.4 equipped, it does not incorporate the Audio Return Channel feature that is common on most of HDMI 1.4-equipped home theater receivers.
The VSX-1020-K offers excellent audio performance, digital audio and video connectivity, and innovative features, such as comprehensive MCACC setup, Internet Radio access, and even an iPhone remote control app, but does lack some analog connection options, does not support Audio Return Channel or standby video HDMI pass-through, and has below average video deinterlacing/scaling performance. On the other hand, for a receiver with a suggested price of $549, the VSX-1020 is worth consideration.
