Useful Information About Tablet-Controlled Digital Mixers

1. Mixing From Anywhere
2. No More FOH Space Needed
3. Mixer as Stagebox
4. Sound Possibilities
5. Memory Presets

A few years ago, achieving professional live sound involved significant effort. Large racks of effects units were placed next to the mixing console, and long multicore cables had to be run to the stage. Since the rise of digital mixers, even smaller bands can take advantage of all sonic possibilities. Tablet support for remote control offers even more benefits. In summary, a digital mixer with tablet control is now an unbeatable solution thanks to its many advantages.

1. Mixing From Anywhere

Mixing with a tablet allows sound evaluation from any position in the room. After all, the FOH engineer can't walk around the venue carrying a 32-channel desk with cables just to adjust the sound from different perspectives. While it's nearly impossible to create a "perfect sound" that pleases every guest, tablet control allows adjustments from anywhere to achieve the best possible compromise.

2. No More FOH Space Needed

A fixed FOH position not only takes up unnecessary space in front of the stage—space that could be used for paying guests—but also ties sound evaluation to a specific point. With remote control via tablet, the sound engineer can blend in with the audience unnoticed and doesn't have to worry about guests placing drinks dangerously close to the mixer.

3. Mixer as Stagebox

Since many digital mixers now have few or no physical controls, it no longer makes sense to position them offstage. Instead of routing a thick multicore cable from a stagebox to a control console, a tablet-controlled mixer can simply be placed on stage and connected directly to input sources. This not only eliminates the need for long cables but may also make DI boxes unnecessary on stage due to short cable runs. For example, a keyboard can be connected directly to the mixer, which typically provides combo jacks compatible with both XLR and 1/4" connectors.

Multicore Cable
A multicore cable is essentially an extension cable that bundles multiple XLR extensions (e.g., 16 or 32), making mixer inputs accessible on stage. On the mixer side, the connectors are typically male XLR plugs; on stage, they are usually housed in a "stagebox"—a shoebox-sized unit with neatly arranged jacks.

4. Sound Possibilities

Thanks to digital DSPs, digital mixers leave little to be desired. They combine sound processors, advanced equalizers, and more in a single unit that used to require many analog devices. Essentially, a digital mixer is a specialized computer with a finely tuned audio interface and input/output panel. External hardware can still be integrated via insert points, but is rarely needed thanks to the high quality of built-in effects and mic preamps.

5. Memory Presets

Besides sonic features, digital mixers also offer memory presets: meaning that a setup with all settings can be saved and recalled at any time—saving lots of time during soundchecks. When a band plays with the same or similar setup, saved configurations can be reused for the next gig. In theory, the sound should be identical to the last show. In practice, some tweaking is usually needed due to different room acoustics. These presets, often called “Scenes” or “Shows,” can be recalled with a single button—something unimaginable with an analog mixer.

What to Consider When Buying?

1. Number of Inputs
2. Number of Aux Sends
3. The App Is Key!
4. Router
5. Operating System

1. Number of Inputs

Before purchasing a new mixer, assess how many input channels are actually needed. Especially when miking a drum kit professionally and using multiple vocal mics, a 16-channel mixer may quickly reach its limits. App-controlled mixers with 24, 32, or more inputs are now far more affordable, as they lack many bulky components like faders and knobs.

Channel Strip
A channel strip bundles all options for shaping an individual input’s sound and is usually arranged vertically on a console. At the top is the gain control, followed by EQ, effects, aux sends, and controls like low cut or solo/mute. Many of these features are visually represented in tablet apps depending on the manufacturer.

2. Number of Aux Sends

Not only the inputs but also the outputs should be considered in planning. Pay close attention to the number of monitor sends needed, as these will use the available aux channels. Also consider whether monitoring will be mono or stereo. A four-member band wanting independent stereo mixes would require at least eight aux sends. Some manufacturers now offer solutions that free up aux sends for effects or alternative outputs by avoiding their exclusive use for monitoring.

3. The App Is Key!

Generally speaking, many app-controlled mixers are on par in terms of sound, preamps, and effects. It makes sense to factor in the app when buying. A good workflow is essential—especially during stressful moments like soundcheck. Most manufacturers offer demo modes in their apps so you can explore and find the one that suits you best.

4. Router

Even the best mixer is useless if the connection is unreliable. Some mixers only support 2.4 GHz Wi-Fi, while others also support 5 GHz, which is more stable when many smartphones or wireless devices are nearby. The safest option is to invest in a high-quality external router and connect it to the mixer. With app-only mixers, always have a backup plan—like connecting a computer via Ethernet cable.

5. Operating System

Most manufacturers offer their apps for Mac iOS, Android, or even Linux (Behringer). Soundcraft uses a browser-based control system, allowing any internet-capable device to connect, regardless of operating system.
