DVL-Digest 632 - Postings: Index Any info on the Sony DSR-11 DV Lap top editing Mic question Any info on the Sony DSR-11 DV - "Perry" From: Bob Andersen Has anyone seen the Sony DSR-11 DV? If so any comments? The DSR-11 is a "stripped down" DV deck that will play mini and full sized DV tapes. It's very small compared to all other full-sized DV decks. I think it records in DVCAM only. I think it is supposed to cost . Lap top editing - "Perry" I've not taken too much notice before, but I now need to know how lap top editing for DV is working out, and it has to be a cross platform solution. I guess that means Premiere or EditDV at the moment. I know of the Sony Vaio and the Gateway with built-in Firewire, and of course the Apple portable - have folk got Premier or EditDV to work successfully with these products? Any particular trick you need to know to get them up and running?

What in the world does that mean? What is a "balanced input signal" and what's the difference between a "balanced" and an "unbalanced" input signal?< I can't help you with the hairy condom but this one is a bit easier! There are actually two points here but they are commonly connected: 1) An ordinary signal lead (like video and the audio in your Hi-Fi) has one 'hot' wire and one return that is commonly earthed (grounded), this is called 'unbalanced'. If you take a transformer output coil and divide it into two halves with the centre tap earthed, then each of the other two taps have an equal but opposite signal, and this mode is called 'balanced'. If you run this type of cable across radiation like lighting cables, the two signal wires will pick up the same interference that should then cancel out. It is also easier to avoid hum via ground loops. Balanced wires are normally terminated in XLR 3 pin connectors or 3 way 'stepped' jacks for use on a 'jackfield'. 2) Traditionally, balanced equipment runs into a 600ohm load which is deemed low impedance. This makes it easier to have long cable runs without picking up interference and suffering from cable non-resistive impedance (ie capacitance or inductance) which could effect frequency response. Consumer equipment tends to be unbalanced and runs into relatively high resistance of several thousand ohms or more. This is usually fine for short connections. You can convert signals between the two standards using a matching transformer or an electronic equivalent. If you are careful you can even do it with a simple lead connected to the right pins.
