Monitor lables with clear transparency printing and lights.
Larger preview monitor.
Remote power switch to shut off all monitors. (x10 system?)
Add Quincy Cable
Add Dish Network
Add local silence alarm
Computers:
Replace CRT monitors with LCD
Finish Ghz network
Server:
Add video DA’s (4x)
Add audio meter, video monitoring on outputs.
Program:
REPLACE TBC with better unit.
The studio video?feed to the MCR room had a Kramer video DA that was putting out to hot a signal. The DA was bypassed and all is well… the magni 400?waveform does not show correct cal even with a test signal inserted! So that needs to be investigated.
More DA’s are needed with a video gain adjust … Link electronics makes some reasonable units.?
The video server record channel now appears to have the correct video level. You can call up the level now on preview.
The Strand Century now has 4 channels failed on dimmer pack 1 its most likely the control PCB.
The control PCB was rebuilt already on dimmer pack 2.
The Dimmers are scuduled to be we wired on may 21-22-23
Items needed are Wiring Tray and SO cord and Ground wire.
The studio grid map needs reworked
Hello I have a Mackie SR32.4 mixing Board.
Its about 7 years or less old SN.9M1811.
I get AM radio on Mic line inputs with a new double shield snake hooked up to sure SM58’s and sure Laples. The nearest AM transmitter is 4 miles or more. The RFI comes and goes depending on weather.Mackie has a solder in RFI filter fix that you can make yourself.. I know as we did it once on diffirent install…
But I see no mention of it here… anyways does someone know of a prebuilt RFI filter xlr cable or barrel for a good price?In older mackies IMHO RFI is a know problem (do a google search) in some cases… Mackie wanted a wide frontend… well its a little to wide ! Like DC to Daylight.. hehe just kidding.. I like Mackie
but AM radio in the mix is a little to much!Any ideas are welcome?
Link to Mackie mystery filter?
Prebuilt filters?Thanks in advance
Vis.here is mackies reply:This LC Filter network has proven to be effective in filtering out AM RFI.
Install this filter by hard wiring it (i.e. soldering) into an XLR shell on the end of a mic cable.Attach the modified end of the mic cable to the mixer?s mic preamp input.
(For very extreme RFI environments, the capacitor can be changed to 0.01mF.)Parts RequiredCoil Digikey part#

Factors such as location and sound system installation techniques can make a drastic
