Given that the Sherwood is a basic stereo/Dolby Pro Logic receiver, and that we have had sources where digital audio (coax and optical) are the standard for Dolby Digital and DTS for well over 15 years, and that HDMI is established now as the de facto standard for AV connections on many home AV products.... perhaps it's time to retire the Sherwood and look for something new.
Entry level price points for new, fully spec'd, AV receivers capable of dealing with HD audio, DD, DTS, Dolby ProLogiic- and ProLogic II have never been cheaper.
Sherwood is still a good brand. It has been joined by Yamaha (
RX-V377BL); Sony (STRDH750); Denon (AVR-S500BT) and Pioneer (VSX-524-K) at the entry-level price point of $249. In real terms these are probably a fraction of what you paid for the Sherwood all those years ago.
Another option is used equipment. There are some really good pre-HDMI AV receivers from Denon, Yahama and Pioneer available in the used market.
Be aware though. Your TV has a DVB-T tuner. It picks up the Freeview standard definition (SD) channels, but not the Freeview HD ones. Dolby Digital sound only comes from the Freeview HD channels.
Your TV will pass Dolby Digital from any source connected to a HDMI port to the Optical Out. It will also pass DTS. But the internal Freeview DVB-T tuner doesn't generate Dolby Digital, just stereo and stereo with Dolby Surround encoding where you use ProLogic II for decoding.
Dolby will only activate when it has information for all 5 channels. For normal stereo only left, right and bass boost speakers work, so you lose center and rear speakers. The system should have an option to play SIMULATED surround sound, to activate all speakers. In many systems, this option is called dolby prologic, simulated or some other fancy name.
After days of frustration the real problem was with the cable box. It needed a firmware update. Following forum advice I disconnected the cable box power cord for a few minutes, reconnected it, allowed the cable box to reinitialize. Turned off receiver and TV. Turned TV back on and set it to HDMI connection, turned on receiver and all worked fine. Great picture and sound.( Needed to buy an optical cable to go from the cable box to the receiver to get sound from the speaker system. )--the dirtybird
THE BEST SOUND IS WHAT SOUNDS BEST TO YOU, HOWEVER DO THIS:
1, USING THE SETUP MIC CONFIGURE YOUR DENON, PAGE 8 OF THE MANUAL. NEXT
2. RAISE THE REAR SPKR LEVELS, PAGE 46,47. NEXT
3. WHEN LISTENING TO AUDIO CD OR RADIO TRY THE 5 CH STEREO DSP MODE.
4. WHEN WATCHING A DVD USE DSP DOLBY PROLOGIC OR TRY 5CH STEREO IF THE MOVIE IS MOSTLY TALKING.
5, TRY 5CH STEREO WHEN WATCHING PROGRAMS WITH MOSTLY TALKING
IT IS ALWAYS BEST TO CONNECT ANALOG AUDIO IN ADDITION TO THE OPTICAL, COAXIAL OR HDMI AUDIO CONNECTION. IF USING OPTICAL OR COAXIAL CONNECTIONS BE SURE TO CONFIGURE IT IN THE RECEIVERS DIGITAL ASSIGNMENT AREA IN SETUP.
ALSO, ON THE FRONT OF THE RECEIVER IS AN INPUT MODE BUTTON, PRESS THIS BUTTON UNTIL AUTO IS DISPLAYED
prologic is a form of dolby digital, the 4.0 or 5.1 (versions I and II respectively) to be exact. the type of dolby version is determined by the source disk. the reciever may expand a dolby digital signal into 7.1 but it is actually a 5.1 standard, as is prologicII
