Monitor Mix Calculator

Last updated

Quick answer

Monitor mixes are counted by ear, not by musician. A full band with five players, four vocalists and a drummer needs about 8 mixes and therefore 8 aux sends. Wired personal mixers cost less than wireless in-ears at every mix count, so the choice is about mobility and spectrum rather than money.

The count that matters is mixes, not people. Two backing vocalists who want essentially the same thing can share one mix. A drummer never can, because what a drummer needs bears no resemblance to what anybody else on the platform wants. The worship leader always needs their own.

The second decision is the delivery method, and it is mostly an arithmetic question about spectrum and cost rather than a taste question. Enter your platform below.

Not counting the drummer.

Wireless in-ears compete with these for the same spectrum.

How many monitor mixes does a church platform need?

Five common platform sizes, counted by ear rather than by head. The aux send column is what the console has to provide.

A full band with five musicians, four vocalists and a drummer needs about 8 monitor mixes and 8 aux sends, which is beyond what most small consoles provide.

Aux sends for monitors are on top of the sends leaving the room for the livestream, the overflow, the nursery and the hearing assist system. Check the bus count on a console data sheet as carefully as the channel count.

Wedges, wireless in-ears or wired personal mixers?

All three work. Which is right is decided by how many mixes you need, how much radio spectrum you have left after the microphones, and who actually has to move.

Wired personal mixers cost less per position than wireless in-ears at every mix count, from one upward, and use no radio spectrum at all, which is what the wireless microphones need.

Why stage volume is a house mix problem

This is the reason monitoring matters far more than its share of the budget suggests. Whatever the platform produces acoustically, the congregation hears, and the console cannot subtract it.

Contemporary worship commonly runs 92 to 98 dBA, and NIOSH allows about one hour of exposure at 94 dBA and about fifteen minutes at 100 dBA.

These are levels rooms actually run at, not targets to reach. Offer hearing protection at the door above about 95 dBA and take a complaint about volume seriously.

The spectrum arithmetic nobody does first

Wireless in-ear transmitters use the same UHF television spectrum as your wireless microphones, and they are transmitters rather than receivers, so they consume it the same way. A church running six wireless microphones and six wireless in-ear channels needs twelve coordinated frequencies, not six, and in most US markets that is a genuine coordination exercise rather than a setting.

Wired personal mixers such as the Behringer Powerplay P16-HQ 16-Channel Digital Personal Monitoring Mixer sidestep the problem entirely. They run over one network cable from a hub like the Behringer POWERPLAY P16-D 16 Channel Digital ULTRANET Distributor, cost less per position, never drop out, and leave the whole spectrum for the microphones that have no alternative. The trade is real: the musician is tethered to a position.

So the practical answer for most churches is a hybrid. Put the worship leader, who genuinely must move, on a wireless system such as the Shure PSM300 P3TRA215CL Pro Wireless in-Ear Personal Monitoring System with SE215-CL Earphones, and put everybody else on wired personal mixers. Check what your spectrum will actually carry with the wireless channel calculator before committing.

Frequently asked questions

How many monitor mixes does a church need?

Count by ear rather than by person. A full band with five musicians, four vocalists and a drummer needs about eight mixes: the drummer alone, the worship leader alone, and the rest grouped where people genuinely want the same thing. A small church with a piano and two vocalists needs three. Each mix consumes one aux send on the console.

Are in-ear monitors better than floor wedges?

For the congregation, almost always, because a wedge puts more sound into the room than into the musician and the house mix has to fight it every week. For the musician it is a bigger adjustment: in-ears isolate, which feels disconnected at first and takes several weeks to get used to. Start with one or two positions rather than converting the whole platform at once.

Should we use wireless in-ears or wired personal mixers?

Wired, for almost everybody. At catalog prices a wired position runs a few hundred dollars against roughly a thousand for a wireless one, and that gap holds at every mix count rather than appearing only above some threshold. Wired also uses no radio spectrum, which your microphones need. What wireless buys is mobility, so put the worship leader on it and everybody else on cable.

Can two singers share a monitor mix?

Yes, if they genuinely want the same thing, and two backing vocalists standing together usually do. What cannot be shared is a drummer with anybody, because a drummer needs a completely different balance, or the worship leader with anybody, because they are cueing the service. Sharing where it is reasonable is how a church gets a workable monitor system out of a small console.

How many aux sends do I need for monitors?

One per mix, plus the sends leaving the room for the livestream, overflow, nursery and hearing assist system. A church with eight monitor mixes and three room feeds needs eleven outputs, which is beyond most small consoles. This is the specification that catches churches out, because everyone checks the input count and few check the bus count.

Are in-ear monitors bad for hearing?

They can be, precisely because they work. Isolating around 37 dB means the musician has no reference to room level and can run them far louder than they realise, with a sealed ear canal. Use systems with a limiter in the bodypack, set it deliberately, and explain to the team why it is there. Used properly they are considerably safer than wedges, because the required level is much lower.
