Dear Romy,
I am continuing with testing.
Conclusions at high amplifier volume: -
1) FM tuner variable OUTPUT-2 supplies less background noise than FM tuner variable OUTPUT-1.2) Inserting hard disk recorder into the chain is blameless....

Dear Romy,I have completed testing on my machines and am now satisfied with the results.I have three output sections of the FM tuner able to be switched easily on my amplifier for instant comparison.a) [FM tuner FIXED ANALOG OUTPUT] -> [...

[quote user="Romy the Cat"]Hm, interesting. The problem might be in ADC, I/O cared, Recorder or DAC. When you do the experiment do you record the file? If so then you might plug ADC directly into DAC. Might your problem be with cloaking? I do know wh...

I am sure that recording might be implemented by different means - as long as you feel that you do not lose the quality that FM offers then any means are good.[/quote]Today I set-up FM tuner -> ADC -> DACs -> am...

Dear Romy,Of course I would love to be able to use my personal computer as a music server. I did evaluate music servers (although it was some 2 years ago) and tested the capabilities of my personal computers, including Exact Audio Copy, lossles...

I have been wanting to set up my components for recording of broadcasts for a while now so this would be good incentive to shift my backside into gear.My Sansui TU-X1 has been restored and improvements made. I am very happy with the results at ...
|
|
Dear Romy, it is possible. I would need to obtain some cables to make the connection between my Sansui TU-X1 and Lavry Blue ADC. Also, I do not have access yet to broadband so till then recordings could be to CDR and then I could post the...

Dear Romy, taking ultrasound equipment as an example, there would appear to be much in common in the operation of ultrasound equipment as with a sound system. There is analog signal send/receive, conversion of analog signal received to digital ...

Dear Romy, your adventures with PurePower appear to be frustrating. As an alternative, have you considered contacting the equipment maintenance department of a local hospital to discuss equipment that they use to ensure pure power to instrument...

The station that I most listen to is 105.9 MHz that broadcasts from one location 50 miles away at 100kW power and that is detected by 2 FM aerials mounted as a parallel array with rotator and ~ 40 feet of coaxial cable to the TU-X1. T...

Dear Romy, when you tune in to WCRB what is the reading of the FM Signal/Multipath dial on your Sansui TU-X1?...

The Lavry DA-924 and Sansui TU-X1 are on separate equipment legs/chains and only come together at inputs to the amplifier. They also are on separate uninterruptible power supplies that are on separate legs of our wall supplies. Also,...

Dear Romy,
My tests showed 2 separate types of noise/interference being caused when TU-X1 & DA-924 were switched ON while the TU-X1 was set to OUTPUT FM: -
First noise/interference, the Sansui TU-X1 was passing an AM broadcast on VARIABLE OUTPU...

Dear Romy,I performed the following tests:Test 1.Digital CD source OFF;Digital Domain DD-2 processor OFF;Lavry DA-924 OFF;Sansui TU-X1 ON and set to FM output;Custom tube amplifier ON volume HIGH;ESL-57 speaker arrays ON;Result: no interference and n...

Dear Antonio, there is a picture of the Sansui FA-7 antenna in the TU-X1 brochure and it definitely looks like it is a small external antenna designed for use in high density accommodation. I did not try this antenna. In m...

Dear Romy, my understanding is that Lavry will update their customers' original (db Technologies) DA924 to the equivalent specifications as the new ones leaving the factory today and that includes (for a fee) replacing the power supply to u...
|
|
Dear Romy, advice that I received from Lavry regarding heavy use (6 hours each day) of the DA924 was as follows: "If you really use it that much I would leave it ON but power cycle it one a week. If you don't plan on using if for about 3 days then yo...
|
|
Dear Romy,It may be worthwhile to check what transformer is installed in your DA924 because Lavry did change over to torroid transformers from the laminated core power supply transformer. Also it is a good practice to periodically ship the...

Dear Antonio,
RE: your question about what the FA-7 connector is for, the TU-X1 brochure says:
An "F" type connector is provided exclusively for use with the optional Sansui FA-7.

Dear Romy,Thanks for the information that the sinewave form is only generated when the battery power takes over. The pdf is a good article. I did more research today and located a schematic which backs up what you have said despite t...

Dear Romy,The UPS units are being used in their normal way, as line interactive. The voltage waveform supplied by the Powerware 5115 is a sine wave. This is described briefly in the manual and was important information for me pre-pur...

Dear Romy,I do not know who uses the PowerStation75 so I cannot say whether it is helpful. I use the Powerware 5115 UPS boxes for managing the mains power supply [details on www.nps.com.au under Products and Line Interactive UPS (Corporate...

Dear Romy, regarding your efforts to solve variations in mains power supply, there has been an interesting thread on RAT related to the use of toroids as power transformers that morphed into a discussion about the level of DC offset in mains power su...
