3 OPERATION
3.1DynamicMicrophones
Dynamic microphones are characterized by lower output levels. Hence, more gain is needed to amplify a dynamic microphone to operating level. Occasionally it is necessary to add the
3.2PhantomPoweredMicrophones
Phantom powered microphones such as condenser and ribbon microphones require external power to pre- amplify the microphone acoustic pickup. These microphones typically have much higher output than dynamic microphones. Hence the
3.3InstrumentInput
The Neutrik™ combo jack accepts ¼” plugs from instruments such as guitars and basses. The instrument input is an ultra high impedance amplifier designed to allow an acoustic or electric instrument pickup resonate at its full frequency and dynamic range. Care should be taken not to overdrive the input with instrument preamplifiers.
3.4InsertingCompressors,EQ’s,etc.
Each channel of the M80 features a send jack and a return jack. This feature allows the use of external processors such as compression and equalization devices. Simply connect the send jack, balanced or unbalanced to the input of the external processor. Then connect the M80’s return jack to the output of the external processor. The signal is now routed out of the M80, into the external processor, then back into the M80. The final, processed signal will be available at the M80 channel output XLR connector or the Mix Bus output if assigned to the mix bus.
3.5UsingReturnasLineIn
The return jacks on each channel can be used to insert external audio devices such as tape machine outputs, DAT machine outputs, etc. This then makes the audio device available to the mix bus for mixing in with microphones or instruments.
