OctoPre LE

Artikel

The phantom power on the Octopre LE is globally switched in and out so if you are recording with condenser mics that require phantom power, any dynamic mics (that do not require phantom) that you are...
The level you set the mic pres to is dependent on the input signal level and the maximum input level of the next part of the signal chain. If you are recording with a mic that has a low output level...
Most notable is the pre-amp designs. They are similar in performance but not identical. The original OctoPre is a typical Class A Platinum design, (based around a 737 Rhom transistor) the LE is an op...
Do not worry - this is normal behaviour. Note that for mic inputs the input gain range is +13 to +60 dB. This means that when the knob is fully left the signal still has 13dB of gain applied to it...
The problem here is that the mic does not have a very high CMRR (noise rejection). The hum resulting from the phantom power circuit in the Octopre LE will be rejected by better designed, more...
