Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a preamp. The dbx 4 channel tube mic preamp is exactly that - it's a simple preamp that hits all the right notes. The Dbx 286S processor has rather simple compressor and equalization controls which can work well for many applications. It allows you to make the voice sound very natural. It is great for a studio quality mic preamp/channel strip processor. It is electronically very accurate, allowing for seamless butt-end edits without the need for cross-fading. The detented pots make it easy to adjust repeat setups and closely match 2 mono units.

The sound-gate really does an excellent job of keeping room noise out of your recordings. It is ideal for generating pro-sounding vox for a video project. The build quality is good, the controls are postive and accurately labeled, and the options it offers make it very flexible. The great unit does a spectacular job of cleaning up background noise and is a great tool for VO.

• Adds a high pitch static noise
• Easy to install and simple to operate, plus dbx quality
• Great product for recording rap vocals
• Really brings the quality of the vocal up a few notches

Best For podcast: Triton Audio 4 Channel Tube Mic Preamp

Buy on Amazon

Best part: triton audio 4 channel tube mic preamp costs comparatively low and it is available to ship in 24 hours. If you don’t have a preamp for your dynamic mics this is a great affordable choice. It is an ultra-low noise, high quality, in-line microphone preamplifier. It provides noise-free boost to signal from low output ribbon microphones, eliminating need for boutique ribbon preamps.

This device will work on either of those mics,one at a time. While it's a great sounding dynamic mic for vocal work, it has one big drawback. It will only work with dynamic mics and does need phantom power to work properly. The preamp is nestled in a small draw string bag, with the Triton logo printed on it. This unit does pass phantom power through so your Rode Condenser mic will get power.

• Extra coloration, simply more gain and lower noise floor
• Designed for ribbon and dynamic microphones
• 60 db of gain required by the sm7b can introduce unwanted noise
• Excellent gain and low noise with shure sm7b

Best With compression: ART Mic Preamp

Buy on Amazon

The art mic preamp is capable of outshining several other preamp featured in this list in overall features for the price point. This unit has a $50 mic and a $500 mic sound equivalent. It has special circuitry that phase-shifts the program based on frequency to align the bass with the other frequencies (to correct delays introduced during the recording process) for stronger, more balanced bass. It also has 2 spdif digital inputs. It has 4 analog inputs and it is a lot of bang for the buck.

The overall light levels generated by the TPS II, are pleasant without being as harshly bright as many devices with VU meters. It does have balanced and unbalanced outputs. It includes a tube as part of the circuit to add some harmonic coloration and distortion. It gives you a bit more color and control over the tone of your microphones.
