Hey guys! Ever wondered what those mysterious “AUX” knobs and jacks are doing on your Behringer mixer? Well, you're in the right place! The auxiliary sends, often shortened to AUX sends, are super useful features that can seriously expand your mixing capabilities. They let you route audio signals from individual channels or groups to external processors or monitoring systems, without affecting the main mix. Think of them as extra pathways to send your sound wherever you need it! Behringer mixers, known for their affordability and versatility, pack quite a punch when it comes to AUX sends. Let's dive into the nitty-gritty of what AUX sends are, how they work on Behringer mixers, and why they're essential for both live performances and studio recording.

What are AUX Sends?

Let's break down what makes AUX sends so important. Essentially, an AUX send is a control on your mixer that allows you to create a separate audio signal path, independent of the main mix. Each channel on the mixer typically has one or more AUX sends, and each send has a corresponding knob or fader that controls the level of the signal being sent. This level determines how much of that channel's audio is routed to the auxiliary output. The signal from the AUX send is then sent to an AUX output, which is usually a jack on the back of the mixer. From there, you can connect it to various external devices, such as effects processors, stage monitors, or recording interfaces. The beauty of AUX sends lies in their flexibility. For example, you might want to add reverb to the vocals but not to the drums. With AUX sends, you can route the vocal channel to an external reverb unit and then return the processed signal to the main mix. Similarly, you can create a separate monitor mix for the musicians on stage, allowing them to hear themselves clearly without affecting the audience's sound. In essence, AUX sends offer a way to tailor your sound and routing options, providing greater control over your audio.

Types of AUX Sends

Okay, so you know what AUX sends are, but did you know there are different types? Understanding these differences is key to using them effectively on your Behringer mixer. The two main types of AUX sends you'll encounter are pre-fader and post-fader sends. Pre-fader AUX sends take the signal from a channel before it reaches the channel fader. This means that the level of the signal sent via the AUX send is independent of the channel fader's position. So, even if you turn the channel fader all the way down, the signal will still be sent through the AUX send. This is particularly useful for creating monitor mixes. Musicians can adjust their own monitor levels without affecting the main mix. On the other hand, post-fader AUX sends take the signal after it has passed through the channel fader. In this case, the level of the signal sent via the AUX send is dependent on the channel fader's position. If you lower the channel fader, the signal sent through the AUX send will also decrease. This is commonly used for sending signals to effects processors. When you adjust the channel fader, the amount of signal sent to the effects processor changes proportionally, maintaining a consistent balance between the dry and wet signals. Some Behringer mixers also offer switchable AUX sends, allowing you to choose whether they operate in pre-fader or post-fader mode, giving you even more flexibility.

AUX Sends on Behringer Mixers: A Practical Guide

Alright, let's get practical. How do you actually use AUX sends on a Behringer mixer? The process is pretty straightforward, but understanding the steps is crucial. First, identify the AUX sends on your mixer. Behringer mixers usually have several AUX sends, labeled as AUX 1, AUX 2, and so on. Each channel will have a corresponding knob or fader for each AUX send. To send a signal from a channel to an AUX output, simply turn up the corresponding AUX send knob on that channel. The amount you turn it up determines the level of the signal being sent. Next, connect the AUX output on the back of the mixer to your desired external device. For example, if you're sending the signal to a reverb unit, connect the AUX output to the input of the reverb unit. Then, connect the output of the reverb unit back to a spare input channel on the mixer. This allows you to blend the processed signal with the main mix. Finally, adjust the AUX send levels on each channel to create the desired mix for your external device. If you're creating a monitor mix, you'll want to adjust the levels so that each musician can hear themselves and the other instruments clearly. If you're sending signals to an effects processor, you'll want to adjust the levels to achieve the desired amount of effect. Remember to check whether your AUX sends are pre-fader or post-fader, as this will affect how the channel fader interacts with the AUX send level.

Setting Up Monitor Mixes with AUX Sends

One of the most common uses for AUX sends is creating monitor mixes for live performances. A good monitor mix is essential for musicians to hear themselves and each other clearly, leading to a better performance. To set up a monitor mix with AUX sends, first, decide which AUX send you want to use for the monitor mix. It's generally recommended to use a pre-fader AUX send for monitor mixes, as this allows musicians to adjust their monitor levels independently of the main mix. Connect the AUX output to a headphone amplifier or a powered monitor speaker. If you have multiple musicians, you may need multiple monitor mixes, each with its own AUX send and output. Next, adjust the AUX send levels on each channel to create the desired mix for the monitors. Start by adding the channels that the musician needs to hear most clearly, such as their own instrument or vocals. Then, add the other instruments and vocals as needed, adjusting the levels to create a balanced mix. It's important to communicate with the musicians to get feedback on the monitor mix. Ask them if they need more or less of certain instruments or vocals, and adjust the levels accordingly. This iterative process will help you create a monitor mix that works well for everyone. Also, consider using in-ear monitors for a more controlled and consistent monitoring experience. In-ear monitors can help reduce stage volume and improve clarity, leading to a better overall sound.

Using AUX Sends for Effects Processing

Beyond monitor mixes, AUX sends shine when used for effects processing. Effects processing adds depth, texture, and character to your sound, and AUX sends provide a flexible way to integrate external effects units into your mixing setup. To use AUX sends for effects processing, first, choose the AUX send you want to use for the effects. Post-fader AUX sends are generally preferred for effects processing, as this allows the amount of effect to change proportionally with the channel fader. Connect the AUX output to the input of your effects processor. Then, connect the output of the effects processor back to a spare input channel on the mixer. This allows you to blend the processed signal with the dry signal from the original channel. Adjust the AUX send level on the channel you want to apply the effect to. The higher the AUX send level, the more of the signal is sent to the effects processor, resulting in a stronger effect. Use the return channel's fader to blend the wet (processed) signal with the dry (unprocessed) signal. This allows you to control the overall level of the effect in the mix. Experiment with different effects processors and settings to create a variety of sounds. Reverb, delay, chorus, and flanger are just a few examples of the many effects that can be used with AUX sends. Remember to use effects judiciously and avoid over-processing your sound. A little bit of effect can go a long way.

Troubleshooting Common AUX Send Issues

Even with a good understanding of AUX sends, you might run into some issues. Don't worry; most problems are easily fixable! One common issue is a lack of signal in the AUX output. First, make sure that the AUX send knob on the channel is turned up. Also, check that the AUX master level (if your mixer has one) is turned up as well. Ensure that the cables connecting the AUX output to your external device are properly connected and functioning correctly. Another issue can be feedback. This usually occurs when the output of the effects processor or monitor speaker is being picked up by a microphone. Try to position the microphones and speakers so that they are not pointing directly at each other. You can also use EQ to reduce the frequencies that are causing the feedback. Hum or noise can also be a problem. This can be caused by ground loops or electromagnetic interference. Try using balanced cables and ensuring that all of your equipment is properly grounded. Experiment with different cable routings to minimize interference. If you're still experiencing problems, consult the manual for your Behringer mixer or seek help from a qualified audio technician. They can help you diagnose and fix any issues you may be having with your AUX sends.
