Why use preamp on DSLR camera

Preamps are awesome for getting higher-quality sound from DSLR cameras. They offer superior sound and more control of audio recording. Plus, preamps can minimize noise in recordings, making it simpler to edit them later.

In this article, I’ll tell you about the advantages of preamps on DSLRs and provide advice on how to make the most of them.

What is a Preamp?

Preamps are often heard of when it comes to photography. But, what are they? Preamps (or pre-amplifiers) are electronics. They take low-level sounds from the camera mic. Then, they boost them up. This makes them suitable for recording equipment like mixers or audio recorders. It also results in better quality audio with no noise or distortion.

Preamps also offer noise isolation. This helps make sure background hiss, electrical interference and other ambient background noises don’t ruin your audio.

If you’re after professional audio from your DSLR camera, preamps are essential. They make sure you get the best audio quality possible.

Benefits of Using Preamp

As a photographer, I have found preamps so useful. Preamps, also known as microphone amplifiers, are essential for capturing good sound when using DSLR cameras.

Preamps can give you better recordings. Their low-noise gain circuit and higher signal strength will make your recordings sound clearer and more professional. They can even reduce distortion from the microphone. Plus, they can provide phantom power, so no need to search for extra batteries or adapters.

Preamps are great for noisy places. Most pro-grade preamps can suppress background noise, even when there is a high sound pressure from other sources. This is especially helpful when shooting indoors and dealing with echoes.

In short, preamps have been helpful for me in capturing good sound. If you want to upgrade your video and audio production process, try one!

How to Use Preamp on DSLR Camera

Photogs, we can sometimes face scenarios where preamps must be utilized to raise mic and audio levels on our DSLR cams. This is a major component for capturing audio in the wild.

In this article, let’s go over how to use preamps to get the best possible audio from DSLR cameras!

Connecting the Preamp to the Camera

Ready to get better audio for your DSLR videos? Connecting a preamp is the way to go! Here’s what to do:

  1. Gather all the right equipment – like phantom power, adaptors and extension cables – before connecting the preamp.
  2. Plug an XLR cable from the preamp output to an XLR input on the camera, and then plug a cable from the stereo output of the camera into an input on the preamp – you may need an adapter.
  3. Label each input and output clearly.
  4. If your device or mic needs it, switch on phantom power by adjusting settings. Check if the mic needs it first!
  5. Now adjust audio levels, using both the camera settings and the preamp controls (if possible). Make any necessary EQ adjustments before shooting.

Follow these steps for great sound quality on your DSLR videos!

Adjusting the Volume and Gain

A preamp is key to great audio recordings on a DSLR camera. It evens sound and amplifies weaker signals, creating optimal audio quality.

Adjust the volume on your camera. Then, set the gain just loud enough to hear but not too loud that it’s distorted. This helps create more consistent levels.

To pick up quieter audio levels, try a higher-gain mic like a shotgun. Make sure it’s facing directly towards what’s being recorded for ideal capture!

Types of Preamps

Recording audio on a DSLR? Preamps can help! They come in many shapes and sizes. Let’s check out the different types of preamps, and their advantages. Each one offers something a bit different. So, find the preamp that works for you!

External Preamps

External preamps bring sound quality and flexibility that onboarding preamps cannot. They are must-haves for professional audio recording and situations that need major line input boosts.

External preamps enable you to control the audio signal. You can adjust the gain, flow, and A/D conversion. You can also have multiple devices that work together to change audio details like frequency, coloration, and phase balance.

The downside of external preamps is the cost and extra cabling. But this is usually overlooked due to the improved quality.

There are self-powered and powered versions. The powered ones require external power sources. Self-powered versions use batteries or phantom power.

Focusrite, Zoom, and Rode VC1 offer external preamps designed for DSLR cameras. They vary in price depending on what you’re after. Research to find the right preamp for you before purchasing!

Internal Preamps

Internal preamps are a typical feature on DSLR cameras. They boost the mic signal and improve sound quality before sending it to the recording device. Having an internal preamp can make a big difference for sound recording.

DSLR preamps have various levels and types. From basic circuitry to advanced features such as phantom power and high-pass filters. Usually, with an external preamp, there are two main gain stages. The main gain is the output level between 0 dB and +60 dB. The second stage is trim or fine tuning that goes from -20 dB to +15 dB, depending on the preamp.

Some models offer both combination jack connectors (XLR) and 3 pin connectors (for condenser mics) or tosix pin ports (for wireless systems). Others offer one type of port. Before deciding, it’s important to check the model’s specifications.

Internal DSLR preamps often come with extra features. For example, headphone output volume controls for monitoring sound levels before recording audio. Some models even provide built-in EQ controls for further refinement of sound quality. A good internal DSLR preamp is key to capturing good audio with your camera. So, find one that fits your budget and technical needs!


Preamps and DSLR cameras are a great pair! They offer many advantages to those serious about video or audio. Better sound quality and control of sound levels are just a few of these benefits.

Plus, with a preamp, post-production workload is reduced, leaving more time to create an awesome story.

Using a preamp for your DSLR camera should not be taken lightly. It gives complete control over sound recording, with adjustable settings. Furthermore, many preamps also have noise suppression and increased input sensitivity – great for demanding production tasks!

In conclusion, preamps are a great way to boost your news production quality. They’re not too expensive and can make a huge difference to capturing crisp audio. So, pour love into it and enjoy the beautiful shots you worked so hard for!
