[SBE-89-Alaska] Studio Hub "MJ-DASDEC"

[Steve Hamlin]

Three if you are moving up to the DASDEC-3 with up to 6 inputs (3 pairs, yes, still minis).

FYI,

It takes TWO of these to feed all four of the DASDEC inputs.

Each MJ-DASDEC takes 2 Studio Hub stereo analog +4dbm audio inputs and makes 2 mono analog 150 mV 3.5mm (1/8 inch) tip-ring-sleeve (TRS) mini plugs with the correct level for the cheesy computer audio line-in level jacks on the DASDEC monitor.  SH input #1 to TRS left and SH input #2 to TRS right.

Do not confuse this with the PROGRAM audio connections.  This is just the monitor inputs.

All,


I am finally ordering one of these and it looks to be a great plug and play solution.

Hi there,

Having struggled with the unbalanced, low level, split  left/right 3.5 mm plug for DASDEC monitor inputs I thought there must be a better way.

What if you could deliver +4 dbm balanced broadcast standard audio on an RJ45 with the Studio Hub standard and have it come out on a couple of 3.5 mm 3-conductor plugs at the correct "computer line in" level to feed the DASDEC?

No more crosstalk from accidentally connecting the "-" side of the balanced audio to ground, no more distortion from feeding +4 into a -10dbv input, no more cannibalizing mini-plug cords and rolling your own attenuator pads and building them out on barrier strips.


So I emailed Mike "Catfish" Dosch at Angry Audio.  He said he could do it for about $200 a pop.

This is just on paper but Catfish must have been bored today so he actually sat down and made this schematic.
Cool, huh?

John

Schematic attached.

Audio 1 pro balanced stereo or mono to J1
Audio 2 pro balanced stereo or mono to J2

Audio 1 summed and attenuated to J3 pair 1
Audio 2 summed and attenuated to J3 pair 2

If you plug in a StudioHub CABLE-MINIM into J3, you’ll get:

Audio 1 on the tip
Audio 2 on the ring
Shield referenced to the shield of your source equipment

What do you think?

thanks for your interest.  I thought of you when I was trying to solve this and make it easy for entry level technical types to connect this and have it work correctly the first time ( on such an important system )
