Optimal Volume Levels

When using wedges, monitor engineers often find themselves in the middle of a volume war between the amplified and the unamplified. Vocalists, acoustic guitarists, and keyboardists can’t hear themselves over amplified electric guitarists and bassists, let alone over the drums, which are naturally loud. So, they all ask, “Can you turn me up?”
“Maybe,” is the best the engineer can offer due to the limitations imposed by power amplifier size, power handling of the speakers, and potential acoustic gain. If the room acoustics are poor, then peace is even harder to achieve. With an in-ear personal monitor system, performers enjoy studio-quality sound in a live-sound context. They can choose what they hear, and engineers aren’t stuck fighting a losing battle.

Elimination of Feedback

If you understand what causes feedback, then you’ll understand why in-ear personal monitors are the clear choice over wedges.
Feedback happens when amplified sound from a loudspeaker is picked up by a microphone and re-amplified. This often occurs on crowded stages where microphones and monitor loudspeakers are too close together. When an entire band asks the engineer to turn up their mics, feedback is inevitable. Gain-before-feedback is the amount you can turn up a microphone before feedback occurs. In-ear personal monitor systems eliminate gain-before-feedback issues by sealing the “loudspeakers” in the ears of the performers, thereby isolating them from the microphones.

Hearing Health

Repeated exposure to high sound pressure levels from wedges can cause hearing loss. Earplugs help some performers, but even the best plugs alter frequency response enough to make the audio sound muffled. When performers use them properly at appropriate volume levels, in-ear monitors offer as much hearing protection as earplugs while simultaneously delivering to performers only the sounds they need to hear. With the controls in their hands, performers can adjust the volume as needed. It’s the best-case scenario in hearing health.

Reduced Vocal Strain

The most powerful singer is no match for an amplified guitar turned way up, or even a drum kit as-is. When singers can’t hear themselves over the stage mix—which often happens with wedge monitors—they push their voices too hard. The voice is a body part and subject to strain, which can damage vocal chords and shorten singing careers. In-ear personal monitors allow singers to hear themselves clearly, without having to scream over guitar amps and wedges. In addition to their own vocals, singers can include in their mixes as much or as little of the other instruments as they like.

Portability

A traditional floor monitor system includes at least three wedges weighing roughly 20 kg each, plus at least one amplifier at 25 kg each.
A complete in-ear monitor system fits in a briefcase, additionally, eliminating the clutter of wedges and speaker cables gives the stage a cleaner, more professional look, which matters for bands performing at weddings, worship services, and corporate events with different aesthetic standards than the average night club.

Mobility

When you use wedge monitors, you’re limited to a sweet spot onstage where the mix sounds as good as it gets. The directional nature of loudspeakers, especially at high frequencies, accounts for this effect. Using in-ear monitors is like using headphones: the sound goes where you go. So, if the lead singer wants to play to the crowd on either side of the stage, she hears the same mix wherever she goes.

Personal Control

The most empowering aspect of in-ear monitoring is having direct control over what you hear. You’ll still rely on the monitor engineer for fine adjustments, but you can adjust the overall volume and choose different mixes yourself.
To adjust the volume, simply turn the knob on the bodypack. If you use a stereo mix, you’ll hear the same mix in both ears, but you can pan left and right in case you want to hear more or less in either ear. If you use a system with MixMode®, you’ll hear a summed mix in both ears. From there, you can use the bodypack controls to adjust the balance of the sound sources. For example, you might prefer to have vocals and guitar in the left ear, and drums and bass in the right.
When band members control their own mixes, the monitor engineer can concentrate on creating the best possible audience mix.
