Avalon VT-737sp 

Avalon VT-737spThis is a new studio processor, which successfully combines all the basic functions of a tube-type preamplifier, an opto-compressor, as well as a multi-band equalizer.

In particular, in the preamp section, the developers provided 3 inputs: a microphone (transformer type, equipped with 48V phantom power), an instrumental one (jack located directly on the front panel), and a balanced linear type, made on the basis of discrete circuitry class A.

The VT-737SP preamp doesn’t have the bright and rich “top” characteristic of many existing tube preamps. Rather, its sound can be called smooth and natural. But the low-frequency range amazes with its depth and linearity, which creates an incredible sound effect. Perhaps this feature is associated with the operation of the transformer at the microphone input.

It’s necessary to note the high-quality operation of the High Pass filter located in the input section, which, if necessary, is capable of delicately cutting out the low-frequency component in the signal. Adjustment of the upper limit of the filter is made smoothly and in a wide range of 30-140 Hz. Instrumental input has a slightly more colored sound.

The VT-737SP provides excellent sound output in most studio or concert use, but the most extreme styles of music may require a different, alternative solution. Combining a number of unique advantages, the device as a whole has a universal focus, which allows us to recommend it as the main, and in some cases as an additional microphone processor of a professional recording studio.

Preamp Buying Guide

What is a preamp? What does it do?

This is the component that takes an audio signal and amplifies it to the required level. This is necessary because of the microphones on the whole form an extremely weak signal that simply doesn’t reach the operating level of the end device. Preamplifier prepares the microphone signal for processing or playback, amplifying it to the linear level.

What should be the primary consideration when selecting a microphone preamp for your task?

mic preampsThe main criterion is, certainly, a SOUND. However, there are other factors that may have a weighty significance.

Number of inputs
Everything is simple: more channels – more microphones can be recorded simultaneously.

Low pass filter
Use microphone preamps equipped with special filters that cut off frequencies below the level of 20-200 Hz. Low-frequency interference, in this case, will be eliminated.

Phantom power preamp
This type of power supply is the most optimal for the operation of condenser microphones.

Integrated limiter
There are a number of cases when a microphone preamplifier with a built-in limiter will be productive. For example, if the signal from the preamp is sent to the input of the audio card. This will eliminate unwanted overloads. But you should be warned that in most of these situations, you obviously overpay for the integration of these devices.

Level indicator
Despite the fact that this is an optional component of the preamp, it’s recommended to test it practically, and you will certainly make sure that this device is useful.

Phase switch
If there is a need to record from many microphones, then the phase switch will definitely be useful.

Microphone Preamp with Equalizer
An equalizer is increasingly common on modern models. The option cannot be considered a category of first necessity. Try it and decide how necessary this function is for you.

Does it make sense to buy a preamp for a microphone, if it already exists in a sound card or mixer?

Definitely, it does. Separate microphone preamps provide better sound than built-in preamplifiers such as many audio interfaces and mixers from the mid-range price range have. In addition, microphone preamps have their own specific sound. And this means that you can buy a preamp that will most suit your microphone by sound. This is especially true of tube preamps.

Tube or Transistor?

Do your recordings require bright, rich sound provided by the tube, or do you rather like clear and clean transistors? It’s up to you to decide on how to equip your home studio, but professionals usually have both types. If you are just starting to work with sound and in plans, you shouldn’t work with large groups yet, we would recommend starting with a tube.

The price of a transistor preamp is usually cheaper. However, an expensive and high-quality transistor device is still better than a tube preamplifier of the “middle” level.

*Hybrid Preamps

Some preamps have both a tube and a transistor circuit at the same time, with a choice or even a combination of them. Attention should be paid to this option if there are approximately the same number of instruments recorded, for example, vocals and instruments, or guitars and keyboards.

Form factor: Rack, “500 Series” or Desktop?

Microphone preamps are available in 3 basic forms: standard rack (19 inches), the “500 Series” module or a desktop device. Some manufacturers produce their popular models in various form factors, for example, rack and 500-series.

The significance of the form follows the preamp function – it depends on how ergonomically you have equipped the studio. Fewer problems with the connection and more free space – more attention to the creative process.

1-channel, 2-channel or multi-channel?

If you are expanding your studio, then you should definitely pay attention to multichannel preamps that will complement the existing 1-channel or 2-channel preamps.

multi-channel preamp

If today you don’t record more than 2 microphones at the same time, the situation may change in the future. And these are investments that should be taken care of in advance: we recommend comparing the “per channel” cost of a multichannel preamp with 1- and 2-channel devices. It often happens that you pay less for a higher quality preamp unit. Well, in the future, when you start working with larger-scale projects, you don’t have to spend any extra money.

Transformer or Transformerless?

To put it very clearly, that preamp can be considered a transformer one, in the construction of which there is a transformer. If it is missing, then we are dealing with a transformerless preamp. Transformer devices are characterized by a more “colorful” sound. So,  lovers of “transparency” will hardly love it. Transformerless circuitry delivers the purest, most transparent signal.

What to pay attention to?mic preamp

Thus, we discussed the main parameters and now you have to ask yourself a few questions to buy a microphone preamp:

  • What will you connect to it and how it will fit into the workspace?
  • How many preamp channels do you need?
  • Do you need additional sound shaping controls?

Please note that we didn’t consider specific situations of using preamps: drums, acoustic guitars, vocals, etc. This is because if you ask 10 specialists what his favorite preamp is for such and such a case, then you will receive 10 different answers. You should look globally: it’s important that the preamp that you take is easy to integrate into your studio and have the additional sound controls you need.

That’s all, there is nothing to add here by and large. The main advice is one – before you buy a mic preamp, listen to it with your microphone and then compare it with other models. We hope this guide to mic preamps was helpful for you.


Conclusion

Well, on this I finish my material. Now you know what a microphone preamp is and what it is for. If you own your home recording studio, I recommend that you still buy such a device. Just before purchasing, pay attention to my advice on choosing this music equipment. Well, be sure to consider preamps in different price categories.

For example, the budget model ART TubeMP sounds pretty good. Behringer Pro MIC2200 is a high-quality device with all the necessary functions and very good sound.

I also showed you high-quality rack devices in the middle price category. There is also something to choose from. If the budget allows, you can consider them.

Of the most expensive preamps, in my opinion, Universal Audio SOLO / 610 deserves the most attention. I was very pleased with its sound, its functionality, and capabilities. I recommend it too!
