How much gain should a mic preamp provide?
A microphone preamp boosts that signal up to line level, which is about 1.2 volts. That increase requires 30 to 50dB of gain. Think about that—60dB of gain increases the signal level by a factor of 1000!
What is a Class A mic preamp?
Let’s break down each part of this: “class A” is a type of amplifier circuit that reproduces the whole audio signal. This is different than a “class B” amplifier which only produces the top or bottom of the sound wave. The negative about a class A circuit is that it uses much more power and thus creates more heat.
Do you really need a preamp?
The purpose of a preamp is to amplify low level signals to line level, i.e. the “standard” operating level of your recording gear. So you need a preamp for just about any sound source. But this doesn’t have to be an external device. Most audio interfaces already come with built-in preamps.
Do I need a preamp?

Is it worth buying a preamp?
Bottom line: An external preamp is a great second step to improve your sound quality or to obtain more sound variety, but don’t make the second step before you’ve made the first. You can make great recordings with just your audio interface’s internal preamps and one or two high quality condenser mics.
Are expensive preamps worth it?
Another main reason why a more expensive preamp sounds better than a cheap one is the quality of the electronic components used in the design. Even though the task of a solid-state phono preamp is relatively simple, the quality of the components and design will have some level of impact on the sound quality.
What does Class A mean audio?
Class A is the most linear type of audio amp, but it has low efficiency. Consequently, these amps are used in applications that require high linearity and have ample power available. Figure 1. A Class A audio amp is typically associated with high linearity but low efficiency.
What does class A discrete mean?
class A: Class-A Amplifiers explained. Discrete: means that no IC’s are used. Instead, the circuitry is entirely made with components such as transistors, resistors, capacitors and diodes etc. etc. Advantage of this method is that you can select the best parts for the job.
What is the history of the V72 preamplifier?
The minor upgrade to the V41b was not good enough, so something better had to be built. And thus was born the famous V72 preamplifier. The name TELEFUNKEN dates back to 1903. The company began as a joint venture between Siemens & Halske and AEG (Allgemeine-Elektrizitãts-Gesellschaft, or General Electric Company).
What is the difference between a V72 and V76?
Essentially the V76 is a pair of V72’s in series, capable of 76 dB of gain, (hence the name). The gain is switchable in 12 steps of 6 dB increments. The V76 has a shelf EQ at 80 Hz and 300 Hz, or a combination of the two.
When did the Siemens V72 stop being made?
By 1963, the era of the V72 had come to an end, as the age of transistors had arrived, and it was replaced by the V72t (‘t’ for transistor). Siemens continued to build the V72 until 1964, and the V72b until 1966, (when Telefunken also stopped production). TAB continued to build the V72a until the mid 1970s.
What is the best microphone preamp for recording?
The V72 and V76 microphone preamps from TAB/Telefunken are two of the most time honored pieces of gear in recording history.
