Onkyo TX-SR876 power consumption

The energy consumption of an Onkyo TX-SR876 receiver was measured using a Kill-A-Watt power meter. The 876 is one of the higher-end Onkyo THX certified AVR's that were reviewed here. It has an HQV Reon-VX video processor, 3 TI DSP chips, and 7 channels of 140W amplification. Here is a list of the watts consumed in the different standby and idle modes:

standby: 0W (default)
standby: 86W (HMDI Power Control on)
idle: 120W (4 ohm)
idle: 149W (6 ohm)

The Onkyo 876 is Energy Star approved and it consumes less than 1W in its standby (off) state. When the HDMI-CEC Power Control mode is enabled the standby energy usage jumps to 86W which is ridiculous in my opinion. Unfortunately the HDMI Power Control option needs to be enabled for the HDMI TV Control to be active, so you can't have any basic HDMI-CEC controls without wasting a lot of juice all the time. It is best to save the planet, and your wallet, and leave the Onkyo's HDMI control options disabled.

The 876 has an amplifier speaker mode for selecting the either 4 ohm or 6 ohm operation. The 4 ohm option dramatically reduces the amplifier power which was required for UL certification. The difference in idle power consumption is almost 30 watts which makes it a good choice if you happen to have external amplifiers and are using the 876 as a pre-amp/processor.

The TX-SR876 was in an open air rack with good ventilation on all sides and it did not get uncomfortably hot. So the rumors of the Onkyo 876 and 906 having a heat problem are false but I'll have to wait for the summer hot months to know for sure. The 876 did get a bit warm but it was definitely cooler than you would expect from a device consuming 120W at idle.

Sony BDP-S350 firmware 015

Firmware version 015 was made available January 29th 2009 for the Sony BDP-S350 Blu-ray player. The S350 automatically detected that a new firmware version was available. Downloading over the Internet and updating was very simple and took about 7 minutes. I really like the way that some networked AV components make firmware upgrades so easy and painless.

Improvements over firmware version 010:
  • Improves BD-Java compatibility to enhance interactivity with some BD-ROMs.
  • Improves BD-Live performance to enhance interactivity.

Some people have reported that the 015 update fixes the Baraka Blu-ray freezing problem. I am skeptical that something that appears to be a laser layer focus/transition problem could be fixed via firmware. I will update this section when more Baraka user reports are in.

The new 015 firmware did not fix the Wall-E Blu-ray DTS audio glitches that I was having with my Lexicon DC-1 pre-amp/processor. The Lexicon DC-1 has DTS firmware from 1997 so it is probably something that can't/won't be fixed externally. It's time for me to upgrade my old DC-1 to something newer that is HDMI compatible with the newer lossless codecs.

The higher end Sony BDP-S550 model also has firmware 015 available with the same improvements listed. The S350 and S550 firmware download files both have files sizes of 51,822,592 bytes but they have different md5sum checksums so they are not the same. I will update this section when I compare the contents of both firmwares and determine what is different.

It has been 4 months since the 010 firmware came out September 30th 2008 that added BD-Live support to the BDP-S350. At this rate the S350 will probably get a couple more firmware updates this year. They will likely only be bug fixes as Sony hasn't announced any future features like their competition has for streaming Netflix, YouTube, and Picassa support. This is sort of discouraging since Sony has such a great track record of adding new features and functionality to the PS3. Time will tell how this affects Sony's AV consumer business.

Wall-E Blu-ray DTS audio glitches

The Blu-ray disc of Pixar's Wall-E experiences several brief DTS audio dropout glitches when played on a Lexicon DC-1 THX AC3 DTS preamp with the v2.01 firmware. The DTS audio plays flawlessly until about 18 minutes into the movie when the first brief audio dropout occurs. The glitch is very annoying and it happens about 20 times during the movie. The dropouts are repeatable and they always happen at the same locations. When it happens the Lexicon loses lock on the 5.1 DTS signal, switches to 2ch 48K PCM, and then reacquires the 5.1 DTS signal all in a fraction of a second.

The Lexicon DC-1 is a 12 year old surround pre-amp that has played thousands of AC3 and DTS movies on LaserDisc, DVD, and Blu-ray without any problems. This particular Wall-E Blu-ray is the first disc that has had any audio decoding problems. It's surprising considering the amount of time, the number of different discs, and how fast technology has changed in pasts 12 years. No audio decoding problems until the Wall-E Blu-ray disc. Amazing actually.

The audio glitches go away if the Sony BDP-S350 Blu-ray player is instructed to decode DTS internally and output 48K PCM 2 channel surround. So the problem is not the player or the Wall-E disc but the ability of the Lexicon to decode the DTS stream.

The Wall-E packaging says that the audio is 5.1 DTS-HD MA (master audio) when it is actually 6.1 channels. The DTS-MA on Wall-E uses a legacy 1.5Mbps DTS core that since it's 6.1 is DTS-ES (Extended Surround) which has six discrete channels. DTS-ES uses a core + extension design where the extra rear channel uses optional packaging flags that in the past haven't caused the Lexicon DC-1 any problems. Somehow this incompatible DTS-ES stream is encoded slightly differently.

The DTS website says this about the 6.1 DTS-ES core + extension:
So, if you have an older DTS-capable receiver, it will “ignore” any extensions and just decode the core — ensuring you of compatibility and very high quality.
Unfortunately that doesn't seem to be the case with the Blu-ray of Wall-E and a Lexicon DC-1. So the only solution is to listen to Wall-E with a 2 channel PCM downmix that lack dynamics, bass, and discrete channel steering. I guess it is time to upgrade my Lexicon DC-1.

Pioneer to stop LaserDisc player production

Pioneer has announced that it will build 3000 more LaserDisc players before it halts production. Currently 3 models of LaserDisc player are still being built and they are all produced by Pioneer. So this signals the end of an era. Production of LaserDiscs stopped in 2001 and Pioneer had continued building players for people who had large collections of discs.

The current Pioneer DVL-919 is a combo DVD/Laser player that has a $1000 MSRP. It lacks the higher end features that the Pioneer Elite CLD-79 and CLD-99 had. Over the past decade the LaserDisc player hasn't seen any technology improvements or cost reductions. Not surprising consider it's a niche production for a niche collector market.

The LaserDisc format arrived in 1980 and 16.8 million players have been sold. Originally LaserDisc was completely analog for both video and sound. Later digital 44.1kHz PCM audio tracks were added and then DTS and modulated AC3. A couple anamorphic discs were also produced. In Japan there was even a HD version of LaserDisc that preceded our current digital HDTV systems by a decade. So LaserDisc had a lot of firsts. To this day no DVD or Blu-ray player can match the speed and smoothness that a high-end player like the CLD-99 could fast forward, reverse, slowmo, and single frame step. We'll miss you LaserDisc.
