Hans Zimmer Interview

Hans Zimmer Interview April 2011 is filled with interesting comments. Only the first 30seconds are not English of part 1. Parts 2 to 4 are just English.



There is a very interesting comment made on his monitoring environment. He doesn't use a sub woofer as it must come across well without one, but loves surround sound. From the recent SOS magazine studio rescue he also explained that he doesn't use a center speaker. Adding that channel is for the mastering and sound stage mixers.

When doing our own mixes, we are most concerned on how it comes across on normal systems. On ear buds, in the car and on small PC speakers. I think it is just another indication that the world of hi-fi is long gone....

But it is at 2:30 in Part 4 that I really like..

"It did have a quality about it, and I don't think it was just luck, you know.
People are talking about the sonic quality of a series III Fairlight while forgetting the output stage of that thing was the same filter , and I "think" the same VCA , as was in a Jupiter 8 or Prophet 5. I mean they ran through those, you know what ever... SSM chips and that was the filter on that thing, ..um… so there wasn't a reason really it should sound THAT much better than something else as everything else was using the same stuff , but I think there was a design aesthetic, and it is the guys building it.
I think the people that built our instruments, I see them as much as artists as I see them as scientists."

.. as I was the guy that designed the audio producing sections of the Fairlight CMI III.

Digital 7 TV Reception Issue and Fix

Recently had an issue with poor Digital 7 (and 7mate and 7TWO) reception, and this post is about what the problem and solution was.

We live in an area in Sydney Australia with very good TV reception. Only need a cheap internal antenna, on the top of a piece of furniture. Very classy. The signal strength shown by the set top box is 100%, except the 7 channels which were 85~90%.

A few months ago we started getting drop outs and image friezes on any 7 channel when it rained, but signal strength was still showing good. Now Digital 44 TVS always has good reception and always indicates less signal, closer to 60%. So what was going on?

On investigation and looking back at when the problem showed up, I came to realize it started to happen after putting an Ethernet switch and some cables near the same piece of furniture. It didn't rain till days or weeks later, so the correlation wasn't obvious, as the reception hadn't changed at the time of install.

The switch was leaning against the antenna cable going to the set top box. The solution was to move the switch all of 20cm away to behind the furniture and not have the antenna cable run along the Ethernet cables.

Also used some CO CONTACT CLEANER on the telescoping rabbit ears joints, but that wasn't the fix. It has now been perfect for 3 weeks, and we have had some almighty storms that caused no problem at all to reception.

It even though the TV signal strength was high, when the antenna was near the switch, that interfered with the received digital signal, causing the error rate to go above that which was recoverable by the set top box.
