USAGE

Attention!

It is recommended to start the NV73d preamp about 30 minutes prior to recording in

order to stabilize its operating parameters.

The NV73d preamplifier is suitable for any recording circumstances. It is great for recording acoustic
and electric guitars, drum kit and all kinds of vocals. The HI-Z input can be used to record bass guitars
and various electronic instruments. The highly driven preamp will be very helpful for recording
instruments of lower quality, by adding harmonics to their sound. NV73d with a very large dynamics
reserve is not inclined to going to overdrive, allowing you to freely work on the sound.

The amplification of the microphone input is adjustable in the range of the -10 to -65 dB.
Such substantial gain is useful when working with classic ribbon microphones and recording
sound effects for advertising or films. All the whispers, murmurs, and other quiet sounds can be
recorded without unnecessary noise and tedious editing.

We can achieve a psychoacoustic effect of sound concentration by skillfully setting the input stage.
This effect occurs with varying intensity depending on the gain level of processed traces, that is why
the input level should be adjusted to suit your personal taste. At higher gain settings a light
compression of the signal occurs, devoid of side effects, otherwise to using an compressor.
This effect is very desirable if we want to slightly take the edge off the signal amplitude peaks.

NV73d can be successfully used on stage. Owing to a compact casing design with a convenient
carrying handle, and a built-in PSU. In addition to the canonical use as a mic preamp or line, we can
connect the device as a high quality splitter with a galvanicly separated symmetrical output.
For example, using the HI-Z input you can connect your bass guitar, delivering the signal from the
unbalanced output to the bass amplifier, and deliver the signal from the balanced output to the mixing
console.
