Powered Mixers

A powered mixer is a type of audio mixer that includes built-in amplifiers. Powered mixers are typically used for live sound applications, such as small gigs and rehearsals. They are also used for recording applications, as they can provide a convenient way to amplify and record multiple audio sources.

How Powered Mixers Work

Powered mixers work by taking multiple audio signals and combining them into a single signal. The audio signals are typically input into the mixer via XLR cables or 1/4″ jacks. Once the audio signals are input into the mixer, they can be adjusted using faders, pan pots, and EQ knobs.

Faders are used to control the volume of each audio signal. Pan pots are used to control the position of each audio signal in the stereo field. EQ knobs are used to adjust the frequency response of each audio signal.

Once the audio signals have been adjusted, they are amplified by the built-in amplifiers and output from the mixer via XLR cables or 1/4″ jacks. The output signal from the mixer can be sent to a variety of devices, including PA systems, recording devices, and headphones.

Types of Powered Mixers

There are many different types of powered mixers available, each with its own unique features and benefits. Some of the most common types of powered mixers include:

• 2-channel powered mixers: 2-channel powered mixers are the most basic type of powered mixer. They have two channels, which can be used to input two audio signals and amplify them.
• 4-channel powered mixers: 4-channel powered mixers are a bit more advanced than 2-channel powered mixers. They have four channels, which can be used to input four audio signals and amplify them.
• 8-channel powered mixers: 8-channel powered mixers are the most advanced type of powered mixer. They have eight channels, which can be used to input eight audio signals and amplify them.

Choosing a Powered Mixer

When choosing a powered mixer, it is important to consider the following factors:

• Number of channels: The number of channels refers to the number of audio signals that the mixer can input. The number of channels you need will depend on the application you are using the mixer for.
• Features: The features of a powered mixer include things like EQ, effects, and routing. The features you need will depend on the application you are using the mixer for.
• Power output: The power output refers to the amount of power that the mixer can provide to the speakers. The power output you need will depend on the size of the speakers you are using and the volume level you need.
• Budget: Powered mixers can range in price from a few hundred dollars to several thousand dollars. Set a budget before you start shopping so that you don’t overspend.

Setting Up a Powered Mixer

Once you have chosen a powered mixer, you need to set it up. The following steps will help you to set up your powered mixer:

1. Connect the mixer to your audio sources. This could include things like microphones, instruments, and other devices.
2. Connect the mixer to your speakers. This could include things like passive speakers, active speakers, or a PA system.
3. Adjust the levels of the audio signals. This can be done using the faders.
4. Pan the audio signals. This can be done using the pan pots.
5. Adjust the EQ of the audio signals. This can be done using the EQ knobs.
6. Set the power output of the mixer. This can be done using the power output knob.

Using a Powered Mixer

Once your powered mixer is set up, you can start using it to combine audio signals, amplify them, and send them to your speakers. Here are some tips for using a powered mixer:

• Use the faders to control the volume of the audio signals.
• Use the pan pots to control the position of the audio signals in the stereo field.
• Use the EQ knobs to adjust the frequency response of the audio signals.
• Set the power output of the mixer to match the size of the speakers you are using and the volume level you need.
• Experiment with different settings to find the sound that you like.

Conclusion

Powered mixers are a versatile and convenient option for live sound and recording applications. They are available in a variety of sizes and channel counts, so you can choose the one that best suits your needs.
