Author Topic: Sondor "Soundhouse" Thomas Jonsson Expert Film Handler Posts: 216 From: Bromolla, Sweden Registered: Sep 2003 posted 10-05-2003 03:09 PM                       Sondor have developed a penthouse reader called "Soundhouse" capable of reproducing not only DolbyDigital but also reverse scan analog and DTS - in the same unit. Has anyone seen or heard anything about it?

Posts: 4143 From: Boston, MA Registered: Apr 2002 posted 10-05-2003 04:05 PM                        Looks interesting. Has anyone seen it in action? Does the time delay buffer introduce a noticeable degration of the analog sound quality?  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

Why DTS should have white light for its reader?

Also, what cost? I thought the reason BACP did not make a combo SRD/DTS reader had something to do with one or the other of the two companies not wanting a dual reader being made. Can anyone shed some light on this? Sam?  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???" Posts: 4247 From: Bloomington, IN, USA Registered: Feb 2002 posted 10-05-2003 08:46 PM                     What are the key differences between the 701 and 702 readers?  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft. Lauderdale, FL, USA Registered: Jun 2001 posted 10-05-2003 09:45 PM                     The 702 has no power supply since the unit taps off the power available on the digital cable between the Dolby processor and the reader. Visual signal status displays are another feature. These where first introduced on the BACP / USL digital penthouse.Sondor is very specialized for the studio market, so a combo head of the two surviving digital formats is a good idea. There is a design for a Dolby Digital reader which mimics the simple layout of a DTS type reader.....did the shrinking market or technical problems make this an aborted project?  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

Indeed, but the only digital time delayed buffer systems I have worked with were the ones on the FP38E - for 16mm mono. I wonder if the time delay in this unit leads to any degration of the optical Stereo quality.  |  IP: Logged Ray Derrick Master Film Handler Posts: 310 From: Sydney, Australia Registered: Sep 2001 posted 10-06-2003 05:15 AM                     It looks like a nice unit although vernier adjustments for the optics would have been a nice improvement. What is it with sound reader manufacturers? None of them offer an intelligent way of making fine adjustments to the alignment. Maybe I need to design one. Back to the Sondor, I would have thought that any advantages obtained by putting the analog reader on the penthouse would be outweighed by the disadvantages. Presumably the output from the analog reader has to be amplified up to line level to get a decent dynamic range through the digital delay system and then attenuated back down so as not to overload the cinema processor's preamp. That's going to add noise. Also if you install one of these with a CP650 and a QSC monitor, the analog audio will have been converted to digital and back three times by the time it gets to the speakers. Just think of all those compounding quantisation errors.  |  IP: Logged Stephen Furley Film God Posts: 3059 From: Coulsdon, Croydon, England Registered: May 2002 posted 10-06-2003 06:57 AM                     Can this thing provide a digital output from the analogue track? That would be the obvious way to go if using a digital processor.  |  IP: Logged Peter Hall Master Film Handler Posts: 314 From: London, UK Registered: Dec 2000 posted 10-06-2003 09:12 AM                        Ray - Tis a std basement set up, with the Dolby analogue preamp card. I guess the delay is at this level ? Have not use in a standalone situation but look after some Nova projectors with these in - a sod to change the LEDS (early Kinotons are a DREAM compared to these - next time will take my 6 year old as his sized fingers are more suited than mine !) but otherwise great. We quoted one for a Ernemann 8 QCing prints in a lab but Dolby were a little hesitant on using a soundhead with a delay  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 10-06-2003 02:52 PM                     Seems odd all the 'softly softly' on delay. It's not like delay is exactly a new or poorly engineered audio technique. Mind you studio quality delay processing is quite expensive, adding to the cost of what is probably quite an expensive rep-set.  |  IP: Logged Peter Hall Master Film Handler Posts: 314 From: London, UK Registered: Dec 2000 posted 10-06-2003 11:52 PM                        Yep, plus this thing states a static delay of 220 frames - what happens if you want to use one on a DP70 ? Or on a Vic 4 or smaller machine ? The digital delay on the FP38E is fun to play with - you have to offset this whenever you change projector speeds (seems that this bit of logic has bypassed the designers )  |  IP: Logged
