GENERAL TROUBLESHOOTING TIPS

Five converter boards (four on the Legacy-14)

are on the Power Stick assembly mounted to the

rear chassis. Each converter board is protected by

a solder-in fuse. A red LED on each board indi-

cates it is working (remove the bottom cover pan-

els to observe these LEDs). The boards convert

the +48 VDC input into +/-19, +5, and +3.3 volts.

A power flow block diagram is shown below.

The console will not function without the Mas-

ter and Slave DSPs and Output 2 installed. These

modules generate several clock signals that coor-

dinate communications between the console mod-

ules. If these are clocks are missing there will be

no module activity (no button LEDs, no meter dis-

plays, etc.). No other modules (Input, C/R, Ses-

sion, etc.) are absolutely essential to “starting up”

the console.

The green LED on the power supply indicates

its 48 volt output is good. Red LEDs on the DSP

cards indicate they are powered. If the power sup-

ply is good, and yet the only lights on the console

are the LEDs on the DSP cards and the dB and

channel lights on the meters, then check the Im-

minent Power Loss signal (as previously shown

in the Power Supply section). With the power sup-

ply on, pins 1 & 2 are shorted (and pins 3 & 4 as

well if a secondary supply is used). If this signal

opens up, it tells the console the power supply has

lost power. This causes the modules to save their

current button settings before the supply voltage

is lost (large supply capacitors keep things pow-

ered up for a very short time). Pins 1 & 2 can be

manually shorted at the mainframe 4-pin connec-

tor to see if this signal is the cause of a start-up

problem.
