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 –20dB pad to the microphone to avoid distortion (e.g. when recording percussion). Do not use phantom power when using dynamic microphones.

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 –20dB pad is almost always necessary when close miking to avoid clipping the amplifier.

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.

M80 specifications

The PreSonus Audio Electronic M80 is a noteworthy piece of audio gear that appeals to both professional studio engineers and home recording enthusiasts alike. Renowned for its exceptional quality and versatility, the M80 stands out in the crowded market of microphone preamps.

At its core, the M80 features eight channels of high-end microphone preamplification. Each channel is built around a solid-state design that ensures low noise and a broad frequency response, making it ideal for capturing vocals, instruments, and any sound source with precision and clarity. One of the standout characteristics of the M80 is its ability to deliver crystal-clear audio without introducing unwanted coloration, allowing users to achieve an accurate representation of the source material.

One of the key technological highlights of the M80 is its variable impedance settings. By allowing users to adjust the input impedance, the M80 can be optimized for a variety of microphones, including dynamic, condenser, and ribbon types. This flexibility not only enhances the performance of the microphones but also enables users to tailor the sound to achieve the desired tonal characteristics.

The M80 also features a comprehensive metering system that includes both LED indicators and a built-in level control, giving users precise feedback on their input levels. This ensures that recordings maintain headroom and reduce the risk of clipping, which is crucial in professional environments where every detail matters.

In addition, the M80 incorporates a unique "air" circuit that allows for an enhanced high-frequency response. This feature helps to elevate the clarity and presence of vocals and instruments alike, adding brightness without harshness.

Another important aspect of the M80 is its robust build quality. The chassis is designed for durability, making it suitable for both studio use and mobile recording applications. Its compact form factor allows it to fit seamlessly into any rack setup, while also being lightweight enough for transport.

Overall, the PreSonus Audio Electronic M80 is a powerful and versatile microphone preamp that offers a plethora of features and high-quality audio reproduction. With variable impedance settings, dynamic metering, and an innovative design that emphasizes clarity, it stands as a great choice for anyone looking to elevate their recording capabilities whether at home or in a professional studio setting.
