Success with the phono equalizer




The Alesis has +/- 12db gain per channel.  I have a total gain range of 24db-36db for compensation.
I examined the RIAA curve and adjusted the 30 bands in each channel to reflect the RIAA curve.
The result compensates for the deficiencies in the recording process as described by the curve.
No need to build/buy a phono preamp.

I examined the data for the B&O MMC4 cartridge and found the type to be a moving iron cartridge instead of a moving coil cartridge. The latter requires more compensation where the former is more like the moving magnet and requires approximately 10 times less gain with a designed in 47kOhm output impedence.

I can use the AV receiver to bi-amp my horns and woofers but doing so will make some playback options unavailable.
I may revert to standard AV 5.1 for video and maintain a separate audiophile system, using the Sansui amps and/or the SX255R, later.

Drive rack, ventilation and wiring.

 My drives have a new rack to hold them. Hot glue and square wood dowels provided the materials with which to build the rack. I used zip ties and a small computer fan attached to the end of the rack to provide cooling air ventilation for the drives. This will increase the lifetime of the drives. Previously the were stacked on top of each other and became noticeably warm during use. The wiring really was bad. Too many cables/wires held together with zip ties. I added a surge protected outlet strip of a newer, more sophisticated design. I rearranged the system wiring to minimize the number of outlet strips and the disarrayed wires. Two strips were screwed to the wall. One was removed. The circular strip was moved from the entertainment center to a work table beside the other two strips and combined with them to supply all devices attached to the system. The strip removed replaced the circular strip in the entertainment system.  Overall, the current setup works better. Both syste...

Philips Hue lights Updated

 Philips Hue lights are known for the ability to program brightness, saturation, and hue using software. Most people use one or more cellphone apps to control their Hue lights. I've a history in computrer science and electronic technology and engineering, so took this up as a new interest. WiFi control of light bulbs' colors has interested me ever since I read aboout the topic some years ago. There happened to be seven Hue bulbs available from one eBay seller and for a reaosnable fee, approximately $20. A bridge device is used to communicate with the bulbs, so I waited for a good deal on eBay and got one. Philips has evolved a developer community and resources for those who want to explore the possibilities in lamp light control. The user joins the communnity and gets a temporary API key, formerly referred to as a 'username', good for one session. Then a browser or app, can be used to send commands to the bulbs. There are other avenues of communication. Python libraries...

Jellyfin media server

 The owner of Emby has blocked my using the WebOS access method of using Emby. I discovered the method and posted on the product's forum. That software is no longer my media server and has been removed from my computers. I replaced Emby with Jellyfin. Jellyfin is the evolved Emby open sourced. Emby was originally open source (and free) but was privatized and monetized by the creator. Many considered that move unethical.  The last open source version became the basis for Jellyfin,  easily competitive with Emby and almost, if not equally, well known. I've been using Jellyfin for about a year, perhaps more. The software has issues but is in constant development but is very useful in the current state, version 10.8.5.
