TS-2000 TX Audio Input?

SawzAll · Post by **SawzAll** » Mon Jul 26, 2010 1:23 pm

Just want to find out if the rear 13 pin DIN plug in the back of the TS-2000 can be wired as a balanced input - like the Icoms can.

I would rather send my outboard mic preamp and digital EQ into a Line Input than a Mic Input.

And if so; what is the pinout for this wiring?
I'm going to get the DIN connector today...

Howdy Sawzall,

The Pinout is the same as on the TS-870 13 pin ACC2.

The diagram for the ACC2 is on pg 95 of the TS-2000 user manual.

The Audio input is pins 11 & 12.
You can see the correct pins for use on this post:

Just remember you have to key this input with the ACC2 PTT pins 9 & 8 as it disconnects the front mic jack and connects the ACC2 audio input.

Good Luck!

An update...

Bought a 13 pin DIN plug from eBay for ~$5 including shipping. Plug is very well made and took only two days after ordering to reach my doorstep. If bought at Ham Radio outlet, the same plug is $22 +tax! Save a little cash and buy one on eBay!

Also bought a 1/4" female inline socket to wire into the same DIN plug for a floor switch push-to-talk. Cost was $1.

I have some Mogami cable left over from wiring my outboard gear together to make this cable in true VOODOO quality.

Also need some tips to wire the audio/receive output to go to an external EQ, amp, and speaker to get that VOODOO receive!

13 PIN ACC2 PLUG.

KENWOOD-TS440-450-680-690-570-711-790-811-850-870-940-950

PIN 1 N/C
PIN 2 N/C
PIN 3 RX AUDIO OUT
PIN 4 SCREEN FOR PIN3
PIN 5 SQUELCH CONTROL OR N/C
PIN 6 S/METER OUTPUT
PIN 7 N/C
PIN 8 CHASSIS/GROUND
PIN 9 PTT- STANDARD MIC INPUT IS MUTED
PIN 10 N/C
PIN 11 MIC INPUT
PIN 12 SCREEN FOR PIN 11
PIN 13 PTT- STANDARD MIC INPUT IS ACTIVE
SHELL EARTH

Soooo....

*Pin 11 is the mic + and pin 12 is the mic -. and shell is ground? Or is ground pin 8?
We are talking about a balanced input here - right?

*Pin 8 and 9 are the PTT - yes?

*Audio out is pin 3 for the audio + and pin 4 is for audio shield - correct?
So if I use 3 & 4 as +/-; then adding shell/ground to it is a balanced connection too?

Just need verification before firing up the soldering iron...

Although the mic inputs have there own grounds (you could call it Signal -),
those are all unbalanced connections.

Try using the pin 8 or the shell as the shield (XLR = Pin 1, TRS = Sleeve)
If you get RFI or hum, try lifting it at the rig.
Its really just wiring it for the best performance.

Take Care,

Sooo, this is a circumstance where a transformer would be ideal - that is - that using a direct box from balanced to unbalanced would isolate the hum.
Hummm...

Thanks...

Hooked it up today.
Pins 8 & 9 for the PTT
Pins 11 for mic audio " + " and Pin 12 for "ground/shield"; used Pin 4 for the mic " - "

Skip was in and I got my first radio check from a FL station (I live in CA); they said it sounded xlnt! I am pleased. Just ran my mic preamp - and nothing else - to make sure everything was running OK before I hooked up 'The Rack'...

I thought I would addend with some more info on the 13 pin DIN plug.

You cannot directly solder the DIN plug that I bought - to the wires.

This situation created a huge obstacle in making this whole thingie work.

Sooooo.....

I bought some thin lugs that would slide onto these very thin pins that are on the DIN plug. I used some narrow shrink-wrap on each lug - after I placed a dab of solder from each wire to each lug. This also tightened up the fit of the 'lug to pin' clearance. It also assured that each lug wouldn't touch another pin - on that very close fit - between pins on the DIN plug itself.
The DIN plug assembled like clockwork after I did it this way.
