Defunct Audio Manufacturers - Pa to Ph
Panalogic
Originally founded in 1981 as Raidek Sound Industries Pty Ltd in the Castle Hill suburb of Sidney, New South Wales, Australia. Introduced one of the first logic steered Surround Sound sound processors in 1985 as the Raidek SD 100, targeting the then emerging home theatre market. The idea behind the unit was simple, the designer was an Australian gent that worked at a local TV station, he realised in the early 80’s that many of the movies supplied to them by American distributors for broadcasting had Dolby Surround encoded on them and with a suitable setup they could be decoded at home into a 4 or 5 channel surround sound setup.
The SD 100 generated a lot of interest but not a lot of sales simply because it was a bit ahead of its time, people just did not have 4 or 5 channel setups at home and creating one could be bit of a nuisance with having to match amplifiers and so on, there simply was no supply of multichannel amplifiers etc. available in that perioid. However the company found a market for the decoder in the film theatre market proper, since it could decode surround encoded films for just a fraction of the price that a proper Dolby Laboratories decoder cost at the time it represented a way for smaller theatre owners to offer surround sound where it was restricted to medium and larger cinemas before that for cost reasons before this. In response to this fact the company introduced a professional version of their decoder in 1988 called the CPS2200 but alongside balanced I/O it offered remote control capabilities, the company also changed its name to Panalogic to reflect the new cinema targeted focus of the operation.
Later in 1988 the company introduced an upgrade to the CSP2200 that had an extra matrix that decoded info from the surround information that could be used for back speakers, they called this “Surround SX” and this technique was later copied by both Dolby and DTS and the company also offered another widely copied invention in 1989 by offering a version with built in crossovers. Panalogic continued updating and introducing new processors and monitoring systems during the early and mid-1990’s with the most notable feature they had was that they were all controllable via serial interface or a more conventional remote control, this allowed operators to use a computer to synchronise the workings of the decoder with other events in the theatre and this was taken to its logical conclusion in 1998 when the company introduced the CA1400.
The CA1400 is an integrated controller for cinemas that could from one place control and synchronise all devices that were used in the theatre from projectors and curtain drawers to amplifiers, the CA1400 also can not only control systems that are designed to be controlled in such a way via serial and Ethernet but also made provisions for systems such as amplifiers and dimmers that that did not have any control capabilities by offering digitally encoded rotary switches and resistors that if retrofitted would in effect make the systems controllable. The company was taken over by Smart Devices in 2005 and their Australian operations shut down and all manufacturing moved to the USA.
Panaudio Industries
Malaysian loudspeaker manufacturer that started out in the late 80's, had by the mid 90's become a fairly large manufacturer particularly as an OEM but all contact with the company was lost in late 2001, unusually for a budget Asian manufacturer of home and car audio they actually had a small line of mid end speakers that were actually quite good, here below is their last known address and contact details. Sometimes also seen listed as "Panaudio Electronics".
Panaudio Industries Sdn. Bhd., No.12 Jalan USJ 19/4A, 47600 Subang Jaya, Selangor Darul Ehsan, Malaysia.

Parsec Delaware Ltd.
USA based manufacturer of radio antennas and related accessories, taken over by Recoton in 1991 after it stopped trading. What makes this company unusual is that it appears to have concentrated on radio aerials rather than TV ones and had a number of small discrete amplified indoor antennas that were popular with audiophiles in the 80's.

Passion Audio Kit
Chinese manufacturer of a large range of valve based amplifiers that were mostly sold as kits although they could be had built, these generated a lot of interest in their time due to being splendid value, in particular the fit and finish was superior to what the other Chinese companies were offering at the time and price. Timeline is ca 1996 to 2001 and there seems to be no information available on what happened to the company or who was behind it.
Pearl Audio Technology 
Italian loudspeaker manufacturer based in Mattarello. The company's website disappeared in 2004 and attempt to reach its owners have not been successful.
Permaton
Interesting this, I was reminded of this company when I found a cachet of old cassettes from ca 1979/81, while I did have a top of the line cassette recorder at the time, I had spent all my summer wages on hi-fi so no money left for good quality cassettes, however this German company supplied chrome cassettes for the same price as others were charging for normal cassettes. Listening to these now after all this time I am stuck by the actual quality of those tapes, they outperform even the cheaper TDK chrome cassettes from that time (and those were quite a bit more expensive, at the least in the eyes of a chronically broke schoolboy), remarkable considering that the recorder was aligned up for the TDK tapes. Trying to find further info on this company on the net and elsewhere, the only thing I have come up with was a paragraph by a German bloke with the exact same recollections of the brand, further info would be appreciated.

Perpetuum-Ebner
Originally founded in 1906 in St. Georgen in the Black Forest in Germany as the Gebrüder Steidinger and was an amalgam of the 2 engineering workshops run by the brothers Christian and Joseph Steidiger. In 1911 after the brothers found it increasingly difficult to work together, Christian bought his brothers part in the company but as he could not raise enough capital to pay Joseph for his share he paid him partially in manufacturing equipment and clockwork parts, Joseph used this material to set up a small workshop incorporated as Perpetuum, and while he started out making clockwork parts the company had evolved into a manufacturer of electric motors, turbines and automation devices as early as 1913. Supplied motors to gramophone manufacturers before and during the first world war but began to assemble their own gramophones in 1920. Perpetuum was one of the first manufacturers to begin to make turntables for home and semi-pro use that featured electric pickups and amplification utilising the Ebner electric tonearm and later when one of the main owner of the Perpetuum company, Hermine Steidinger, married Albert Ebner, the inventor of that very same arm, the 2 companies merged and became PE. After the second world war it became one of the main suppliers of record changers and turntables to integrators and radio manufacturers, but found success in the early 60's as a supplier of standalone turntables. Merged with main competitor DUAL in 1971 and the trademark was discontinued in 1975. Interestingly enough Dual is the name used by the original Gebrüder Steidinger company after the second world war so this was a reunification of the original company after 60 years. More info on this page (in German and an absolutely brilliant page).
Philsaudio
Tiny USA based company run by Phil Abbate that sold CAD software for loudspeaker hobbyist over the Internet, started selling loudspeaker kits in 1998 when he bought the remaining parts stocks of Condor Acoustics but sales were apparently slow and Mr. Abbate stopped that part of the business in October 2000. Philsaudio still holds out a webpage but apparently no longer operates as a business. -- Official homepage.
Phonosonics
Small British manufacturer of kits, most of them audio related in one way or another, timeline ca late 60's to early 90's.
