[sdiy] LED driver cable length

[Dave Kendall]

Hi Guys.

Hopefully an easy one. The band I'm in uses visual clicks for count-ins 
in some numbers, so there's a plan to give the drummer and the 
guitarists a couple of boxes, each with an LED indicator responding to 
a Midi to clock converter driven from the sequencer in a synth. The 
plan is to have the unit in a 1U rack, with a couple of ordinary 1/4" 
TS jack outputs to run to the LED boxes - anode = tip, GND = sleeve. 
The cable runs would be up to 30 feet.

Can anyone see any potential problems using this scheme? The drive 
voltage for the LEDs is 5V via a transistor on the board.

Any thoughts welcome.

cheers,
Dave
