Voltage control
The SMR4P uses the 12 volt rails to generate it's voltages .
On the analoge board we use four different voltages .
Specially the +/- 12 Volt depends of your power supply and is not regulated on the SMR4P.
Note – if your eurorack power supply had - for example 12,3 Volt –
you will measure also 12,3 volt.
Part tolerance
measure of the part tolerance of the regulators it can be, that the voltage can be a little higher or
deeper .
Normally 8 Volt , you measure 7,9.....8,1 Volt – this is ok
Normally – 8 volt , you measure -7,9...-8,3 volt – this is also ok
Normally 5 Volt , you measure 4,9 …5,1 Volt – this is also ok
The difference can come from your Multimeter , or the part tolerance.
Voltages are :
+12volt
-12volt
+8volt
-8 volt
and Ground
All ok ? congrats - you have finished now the analoge board .
