Cinema sound processor quality test in analog

[MarinBNM]

We did discussed this many times, but as I do have big tehnical background in pro-audio, and blind test of equipment is always welcomed there, so I decided to make one on film area. I had some time and did recorded some trailler, projector is same, as well reader and so, on all recordings. There are four cinema processors used and calibrated as it should be, signal which is recorded is Stereo Lt and Rt with SR. Now I want you to listen and told which one you think is best SR sounding. I know this isn't real test as real would be to hear complete unit, but it's something.

 

This are four files, just download it and listen, and normally share you're opinion!

Hi my friend!

A rather difficult test with small laptop speakers. And I am far from home to hook up to my system...but I will give it a try.

Hello Marin,

 

After listening at all 4 files on my laptop I think file 2 is the best.

Yea, sure don't listen to laptop it will sound awfull :D Looking forward to hear you're opinion!

 

Also, real test would be to record all chanells because this is Lt Rt endoced so it a bit mess up :D

Hey Ho Marin ^^

 

Listened to the files and I'd guess files 3 and 4 were some analogue crap Dolby CPs, file 2 must be a digital processor with interesting reproduction...somehow the LF parts of voice are missing I'd say. File 1 sounds really nice.

2 und 3 pumpen wie sonst was, da braucht man nichtmal hochwertige Lautsprecher/Kopfhörer. Variationen im Frequenzgang lassen sich durch EQ ohne Probleme ausgleichen - mangelhaft arbeitende Rauschunterdrückung nicht.

So, Number 2 und 3 are the modern Sony - Junk. Numer 1 and 4 are the Dolby CP´s. Difficult to decide which ist the CP 500 and which ist the CP 50. CP 500 has to be the one with more Sound - Distortion because of the 222 A/SR and so on. CP 50 was upgradet with two 280T in Your Test, I hope.

 

Your sincerely

Martin

How do you know that isn't CP650?

Bemerkenswert finde ich ja schon mal die hoch unterschiedlichen Pegel. Kein Wunder, dass das mit der "7" im Realbetrieb nicht wirklich funktioniert. Nr. 2 hat deutlich mehr Kompression abbekommen, und alle haben sie irgendwie Probleme mit "s"- und Zischlauten - am unangenehmsten Nr. 3 und 4 (und am wenigsten auffällig Nr. 1). Zuordnen kann ich es leider nicht - keine Erfahrung mit moderner Prozessortechnik. Gleichwohl ein hochinteressanter Test.

[MarinBNM]

All processors are played on it's nominal level, problem is output reference on some processors, I have sound card with balanced inputs, and if processor has unbal output normaly level will be lower.

Hello!

 

I was listening to the files on some mid-qual. PC-speakers.

File 1 seams to have the best dynamic range and the lowest

distortion....but it could be complete diffrent...
