A: The CAD Audio E100VP is a large-diaphragm, side-address condenser microphone designed for studio recording and professional audio applications. It uses a solid-state circuit and a 1-inch / 25.4 mm diaphragm to capture a broad range of vocal and instrumental sources.

Its variable-pattern design provides cardioid, omnidirectional, and figure-8 pickup options, allowing the microphone to be adapted to different recording techniques. This flexibility makes it useful when the engineer needs to change the microphone directional response without changing microphones.

A: The E100VP provides three selectable polar patterns: cardioid, omnidirectional, and figure-8. The polar-pattern control lets the user select how the microphone responds to sound arriving from different directions.

Cardioid focuses pickup toward the front, omnidirectional provides a more uniform response around the microphone, and figure-8 picks up from the front and rear while rejecting the sides. These patterns make the E100VP suitable for a range of studio recording and microphone-placement techniques.

A: The microphone uses a 1-inch / 25.4 mm large diaphragm. A large diaphragm is well suited to studio applications where detailed capture of vocals, instruments, and other sound sources is required.

The diaphragm works with the condenser element and solid-state circuitry to produce the microphone audio signal. Its 20 Hz to 20 kHz frequency response allows the microphone to cover the audible frequency range used in many recording applications.

A: The CAD Audio E100VP has a frequency response of 20 Hz to 20 kHz. This range covers the nominal audible spectrum and allows the microphone to capture low-frequency and high-frequency content from a variety of sources.

Actual tonal results depend on the selected polar pattern, sound source, placement, room acoustics, and recording equipment. The microphone variable-pattern design gives engineers additional control over how room and source sound are captured.

A: The E100VP includes controls for polar pattern selection, a -10 dB pad, and a low-cut / high-pass filter. These controls allow the microphone to be adapted to different sources and recording conditions.

The -10 dB pad can provide additional headroom when recording louder sources, while the 100 Hz low-cut filter with a 6 dB/octave slope can reduce low-frequency content below the filter region. The polar-pattern control changes the microphone directional response.

A: The E100VP maximum SPL varies according to the selected polar pattern and whether the -10 dB pad is engaged. The specified maximum values are 127 dB in cardioid, 137 dB in cardioid with the pad, 134 dB in omnidirectional, 144 dB in omnidirectional with the pad, 128 dB in figure-8, and 138 dB in figure-8 with the pad, at the applicable 1% THD specification.

The pad provides additional input headroom for high-output sources by reducing the signal level reaching the microphone circuitry. This can be useful when positioning the microphone near louder instruments or other sources that produce high sound pressure levels.

A: The microphone specified sensitivity changes with the selected polar pattern. It is 14 mV / -37 dBV in cardioid, 10 mV / -40 dBV in omnidirectional, and 20 mV / -34 dBV in figure-8, with the specifications measured at 1 Pa.

These sensitivity differences are part of the microphone pattern-dependent performance. When setting up a recording chain, the engineer should consider the selected pattern and adjust the preamp gain as needed to obtain an appropriate recording level without unwanted clipping or excessive noise.

A: The E100VP provides a specified dynamic range of 118 dB in cardioid, 123 dB in omnidirectional, and 124 dB in figure-8. Dynamic range describes the span between the microphone noise floor and the maximum usable signal level under the specified conditions.

The available dynamic range supports recording sources with varying levels, while the selectable polar patterns can also influence how the microphone responds to the acoustic environment. Proper gain staging and microphone placement remain important for achieving clean recordings.

A: The CAD Audio E100VP includes a 100 Hz low-cut / high-pass filter with a 6 dB/octave slope. This filter reduces low-frequency content below its operating region and can help manage unwanted low-frequency energy.

The filter can be useful for reducing rumble, handling noise, mechanical vibration, or excessive low-frequency buildup depending on the recording environment. It is a selectable microphone control, so it can be engaged when the recording setup benefits from reducing low-frequency content.

A: The E100VP provides a single 3-pin XLR analog output connector for connection to compatible microphone preamps, mixers, audio interfaces, and other professional audio equipment. Its output uses a balanced professional microphone connection.

The microphone requires phantom power for operation. The manufacturer does not specify an operating voltage in the provided specifications, so compatible connected equipment should be used according to the manufacturer phantom-power requirements.
