Martin Audio Loudspeakers for Corporate Spaces: A Buyer's Checklist (Mixer, Reels, Dust Covers Included)

I manage purchasing for a 300-person company. We have a 180-seat training hall, a small courtyard stage, and a conference room that I always describe as “not as small as it looks.” I'm not an audio engineer. I'm the one who signs the P.O. And over the past few years I've bought and maintained a fair amount of professional audio gear.

If you've typed “Martin Audio loudspeakers”, “mixer audio Bluetooth”, “audio mixer reels”, or “audio mixer dust cover” into a search engine, you're probably in a similar situation. Here's the 7-step checklist I use now. Each step has a checkpoint at the end.

What This Checklist Is For

This checklist is for corporate and institutional buyers, not touring engineers. If your project is a large festival or a theater install, you'll need a systems integrator. Honestly, you shouldn't be taking advice from a purchasing admin. But if you need reliable PA gear for a meeting room, training hall, or small venue, this will help you avoid the expensive mistakes I made.

Step 1: Match the Martin Audio Speaker to the Room, Not to the Brochure

When I first heard “Martin Audio”, I thought one model was simply “better” than another. Wrong. The product families solve different problems.

For a corporate scenario, I look at:

• CDD-Live series: If you search “speaker Martin Audio” for a small-to-mid room, this is where I'd start. It uses coaxial differential dispersion, so the audience close to the stage and the people in the back get a similar balance. CDD-Live 8 or 12 is usually enough for a 180-seat hall.
• Blackline series: A budget-friendly option for rental and install. It's still a Martin Audio product, but it doesn't have the same processing capabilities as the more advanced lines.
• MLA and WPS series: This is the high-end, large-scale touring stuff. If you ask me, a corporate training hall does not need an MLA array. More speaker isn't better if the room can't handle it.

Checkpoint: Write down the room size, ceiling height, and audience distance before you ask for a quote.

Step 2: Plan the System, Not Just the Loudspeakers

Martin Audio loudspeakers are professional tools. Most of the performance comes from correct amplification, processing, and subwoofer alignment. I learned this when we added a subwoofer without setting the crossover properly. The bass was heavy in one corner and absent in the other.

You don't need to be a DSP expert. But you need someone who can set up the system. If the quote doesn't include tuning and measurement, it isn't a complete quote.

Checkpoint: Confirm the system includes amplifiers, DSP, and a subwoofer configuration plan.

Step 3: Buy a Reliable Mixer First; Add Bluetooth If You Actually Need It

When I searched “mixer audio Bluetooth”, I was looking for a way to stream background music and still have a microphone for announcements. That's a common need. But not all Bluetooth mixers are equal.

Some have simple playback inputs with RCA-only outputs. Those are fine for a living room, not for a PA system. For a professional loudspeaker setup, you need a mixer with balanced XLR outputs and enough mic preamps. If your budget forces a choice between a professional mixer without Bluetooth and a cheap mixer with Bluetooth, I'd take the professional mixer and add a small Bluetooth receiver. It's more reliable.

To be fair, I have mixed feelings about Bluetooth on mixers. In a low-stakes meeting, it's convenient. But the day someone has a wireless lapel mic and a presentation laptop, you'll want a mixer where the main outputs are solid and all cables are connected.

Last year, I had about four hours to order a replacement before a client event. Normally I'd compare three quotes, but there was no time. I went with the closest dealer and paid about 15% over the usual price. In hindsight, I should have already had a backup mixer in the storage room. I do now.

Checkpoint: Confirm the mixer has XLR outputs, enough mic channels, and a quiet power supply.

Step 4: Buy Audio Mixer Reels for Signal and Power Separately

When I typed “audio mixer reels”, I was looking for cable management. Let me save you the same confusion: there are power reels and signal reels. They are not the same thing.

Power reels are extension cords, usually 16-14 gauge, for powered speakers, monitors, and the mixer. Signal reels have balanced XLR or 1/4-inch TRS cable for microphones and line-level audio. Wrapping a microphone cable around a power reel was one of the rookie mistakes it took me too long to understand: the hum comes right back into the audio. Keep power and signal separate.

For a standard small PA, I'd buy at least one 50-ft signal reel and one 50-ft power reel. Prices vary, but a decent balanced XLR reel isn't the place to save money. Get one with a smooth rewinding mechanism because there's nothing worse than untangling a cable before a client event.

Checkpoint: Label each reel's task and length, and check the cable gauge before you route it.

Step 5: Buy the Audio Mixer Dust Cover After You Have the Mixer

This sounds obvious, but I once ordered a dust cover before the mixer arrived. I guessed the size, and it didn't fit over the rear connectors. The mixer sat uncovered for three weeks and collected construction dust. That was the mistake.

A good audio mixer dust cover isn't a nice-to-have. Dust gets into faders and knobs. A mixer with scratchy faders costs more to repair than a cover. As of early 2025, a fitted cover for a small console typically runs $20-$60 based on distributor listings I checked; verify current pricing for your model.

Checkpoint: Measure the mixer's dimensions including knobs, handles, and rear XLR jacks. Add at least 2 inches of depth.

Step 6: Plan Mounting, Rigging, and Safety Before You Buy

You can buy the best Martin Audio loudspeakers in the world, but if you have no wall brackets or stands that fit them, they will sit in the corner. We spent an unexpected $400 on mounting hardware because our original quote didn't include brackets.

According to Martin Audio installation product documentation, permanent installation should use certified mounting hardware and follow the manufacturer's load instructions (Source: Martin Audio product manuals). I'm not an engineer, so I don't hang speakers myself. We hire a certified AV contractor for anything suspended over people. That's not being over-cautious; it's a safety issue.

Checkpoint: Does the quote include mounting points? Are they rated for the speaker weight? If not, get another quote.

Step 7: Label, Test, and Keep a Spare

The third time we lost sound because someone unplugged a power cable from the wall, I finally made an inventory and labeling system. Every cable has a tag: “Mixer power,” “L speaker XLR,” “R speaker XLR,” “Sub feed.” It took one afternoon. It saves us at least one service call per month.

We didn't have a formal gear sign-out process, either. That cost us when an event staff member took a mixer home overnight and it came back with a bent fader. Nobody admitted it. Now we have a simple sign-out sheet.

Keep a spare amplifier channel, a spare microphone cable, and one spare power cable. A $50 cable is cheaper than a cancelled event.

Checkpoint: Test the whole chain from mixer to loudspeaker before every event. Make it part of someone's job.

Three Things I'd Do Differently

• Don't buy a Bluetooth mixer just because search suggestions say “mixer audio Bluetooth” is necessary. Buy a reliable mixer with balanced outputs, then add Bluetooth if needed.
• Don't use a line array unless you have ceiling height and a real engineer. A pair of well-placed CDD-Live speakers will beat a badly configured array in a small room.
• Don't skip the dust cover or the cable reels. They're boring line items until dust gets in the faders or a tangled reel makes you late.

Bottom Line

For a 200-person corporate hall, a pair of Martin Audio CDD-Live speakers, a mixer with proper outputs, separate power and signal reels, and a fitted dust cover is a sensible, reliable package. There's something satisfying about a rack with labeled cables and a clean cover. If you're on the fence about a purchase, ask for a demo or a local supplier who asks about your room size. If they don't, they're the wrong supplier.

This checklist won't make you an audio engineer. It will stop you from repeating my expensive beginner mistakes. And if you're buying for a 5,000-seat arena, ignore this and hire a systems integrator.
