LED 5 gives a visual indication of the envelope voltage

at the output.

6 Time Range

This 3-position rotary switch lets you select the right

time range for your requirements. The three positions

are:

•

H (high): up to minutes

• M (medium): standard mid-range

• L

(low): down to less than 100 µsec

4. In / Outputs

! Gate

Socket ! is the ADSR’s gate input.

H The gate input is a switched socket, normalled

to the

INT. GATE circuit

on the

system bus

. A

gate signal on this circuit (for instance from a

keyboard) will trigger the ADSR, even without

an input to socket

If on the other hand you connect a gate signal to

socket

then the connection with the system bus is

broken, and the ADSR is triggered from this socket

instead.

If you want, you can undo the normalling to the system

bus more permanently, by turning the A-100 off, remo-

ving the A-140 module, and taking out the little red

jumper in the top right-hand corner of the circuit

board.
