Getting Started

The following steps will help you set up the loudspeakers quickly.

1. Make all initial connections with the power switches OFF on all equipment. Make sure the master volume, level and gain controls are all the way down.

2. If not using a subwoofer, connect the outputs from the mixing console (or other signal source) to the inputs on the rear panel of the loudspeakers.

3. If using a subwoofer, connect the outputs from the mixing console (or other signal source) to the inputs on the subwoofer, then connect the high pass outputs from the subwoofer to the inputs of the loudspeakers.

4. Push the line cord securely into the subwoofer’s / loudspeaker’s IEC connectors and plug the other ends into grounded AC outlets. The subwoofer/loudspeaker may accept the appropriate voltage as indicated near the IEC connector.

5. Turn the mixer (or other signal source) on.

6. Turn the subwoofer on (if applicable).

7. Turn the loudspeakers on.

8. Make sure the loudspeaker’s channel levels are set to (or near) 0 dB.

9. Start the signal source and raise the mixer’s main L/R fader up to a comfortably loud listening level.

Things to Remember:

• Never listen to loud music for prolonged periods. Please see the Safety Instructions on page 2 for information on hearing protection.

• As a general guide, the mixer (or other signal source) should be turned on first, subwoofers next, and DRM loudspeakers last. As such, the DRM loudspeakers should also be turned off first, followed by the subwoofers, then the mixer. This will reduce the possibility of any turn-on or turn-off thumps and other noises generated by any upstream equipment from coming out of the speakers.

• Save the shipping boxes and packing materials! You may need them someday. Besides, the cats will love playing in them and jumping out at you unexpectedly. Remember to pretend like you are surprised!

• Save your sales receipt in a safe place.

DRM loudspeakers are the perfect tool for singer-songwriters touring the local coffee shops. Bring your favorite axe and mic, DRM loudspeakers and cables and power cords.

In this example, a dynamic microphone is connected to the channel 1 input of a DRM212 loudspeaker, used for monitoring purposes.

Now grab your axe and plug it directly into the channel 2 input. Or if you use effects, connect the guitar to the effects input and another cable from the effects output to the channel 2 input.

A DRM215 loudspeaker will be used for the main PA. Simply connect a cable from the DRM212 monitor’s MIX OUT jack to the DRM215 PA’s channel 1 input.

For the output, you will want to set a speaker mode, described in detail on page 12. For this type of setup, Live works well for the main DRM215. Select the Monitor mode for the DRM212 monitor. Additionally, you will want to set the monitor’s configuration > channel 2 input to Hi-Z to account for the guitar.

Here’s how to set up a large club system. In this example, the L/R outputs of a DL16S mixer are connected directly to the CH1 inputs of a pair of DRM18S subwoofers. The Direct Out of each subwoofer is then connected to the inputs of an additional pair of DRM18S subwoofers. The X-Over of these subwoofers may be set to DRM Top.

From here, the high-pass outputs of the two outer DRM18S subwoofers are connected directly to the inputs of a set of DRM315 loudspeakers. The Speaker Modes of these PA loudspeakers may be set to Live (or Club) and the Subwoofer

HPF set to DRM Sub. Talk about beefy low end!

Outputs 1 and 2 from the mixer may be used as aux sends; these are connected directly to the CH1 inputs of a pair of DRM212 loudspeakers to be used as monitors for the band. The Speaker Modes of the monitor loudspeakers may be set to Monitor.

In addition to accepting a balanced mic signal using an XLR connector, these input channels may also accept 1/4" line-level signals driven by balanced or unbalanced sources.

Also, channel 2 may accept a Hi-Z source (such as a guitar) via the 1/4" input without the need for a separate DI box. Be sure to set the Ch. 2 In to Hi-Z in the Configuration menu, though! Directions on page 17.

To connect balanced lines to these inputs, use a 1/4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands for Tip-Ring-Sleeve, the three connection points available on a stereo 1/4" or balanced phone jack or plug. TRS jacks and plugs are used for balanced signals and are wired as follows:

NEVER connect the output of an amplifier directly to a DRM’s input jack. This could damage the input circuitry!

7. Gain [Ch. 3/4]

This gain knob adjusts the input sensitivity of the 1/8" stereo input. This allows signals from the outside world to be adjusted to run at optimal internal operating levels. It ranges from off (knob fully down) up to max (knob fully up).

4. Gain [Ch. 1 and 2]

The gain knobs adjust the input sensitivity of the mic/line inputs. This allows signals from the outside world to be adjusted to run through each channel at optimal internal operating levels.

There is – dB of gain with the knob fully down

(off), ramping up to +50 dB of gain fully up (max).

If connecting mixer outputs to loudspeaker inputs, set the gain knob to 10:00 [“U”] for optimal sound and performance.

8. Mix Out

This is a male XLR-type connector that produces the post-DSP mix – after voicing mode and EQ, but before the alignment delay – from all three input jacks

(with Ch. 3/4 mono-summed). Use it to daisy-chain several DRM loudspeakers together off the same signal source(s).

It is wired the same as the direct outputs as seen to the left.

5. Direct Out [Ch. 1 and 2]

This is a male XLR-type connector that produces exactly the same signal that is connected to the input jack located above it. Use it to daisy-chain several DRM loudspeakers together off the same signal source(s).

After a selection is made, the LCD screen will revert back to the Main screen after 5 seconds of (speaker control) inactivity. You yourself may continue to be as active (or inactive)as you want.

The four speaker modes are as follows:

• Live – This mode is flat, perfect for singer-songwriters and other live performers.

Rotate the speaker control knob to navigate between the selections and push the button to open and edit the parameters.

• Club – This mode is full range, but focuses on increased bass and brilliant high frequencies.

This is the place to start for most DJ / music playback applications.

• Speech – This mode features a significant low frequency roll-off to get rid of unwanted thumps.

It also adds boost and sparkle to mid-range and high frequencies, critical for speech applications.

This plug-and-play mode is perfect for larger venue applications where speech is the primary audio source in need of clear and precise intelligibility.

• Monitor – This mode features a low frequency roll-off and a reduction around 2 kHz to ensure maximum gain before feedback in monitor applications.

MAIN MODE SUB

Simply rotate the speaker control knob until the speaker mode you desire is illuminated, then push to select it. As seen above, we selected Monitor.

In addition to the four speaker modes, there’s a fifth and final selection: the left-facing arrow. Illuminating and selecting this simply returns you to the menu.

The DRM212, DRM215 and DRM315 all have 3-band

EQ with shelving hi, peaking mid and shelving low.

Shelving means that the circuitry boosts or cuts all frequencies past the specified frequency. Peaking means that certain frequencies form a “hill” around the center frequency.

With too much EQ, you can really upset things. We’ve designed a lot of boost and cut into the equalizer circuit because we know that everyone will occasionally need that.

But if you max the EQ, you’ll get mix mush.

Like the previous sub-menus, the EQ also has a left-facing arrow. Illuminating and selecting this simply returns you to the menu.

Let’s talk about those meters now.

That is what’s called a “Real-Time Analyzer”

[RTA for short]. It measures and displays the sound of the corresponding output – amplitude versus frequency components of a continuous signal – via DSP.

An RTA allow you to see what you hear so you may easily locate and eliminate feedback and other anomalies while seeing the EQ changes in real time.

Many audio signals are highly dynamic: music, speech and even environmental noise contain significant changes in spectral content as a function of time. With a digital mixer, musicians and sound engineers can save time setting up at shows by recalling previous settings. The DRM’s RTA fits right in with that, literally displaying frequencies, shortening the time it takes to tune the main loudspeakers or stage monitors during setup in a new room.

There are 15 bands on all DRM Series RTAs.

Push the speaker control knob in to select the ms parameter followed by rotating the speaker control knob clockwise (raise the delay time ) and counter-clockwise (lower the delay time).

Protection Circuitry

DRM loudspeakers employ a built-in limiter for less distortion at peak levels. A dynamic bass response circuit provides optimal low frequency response regardless of overall output level. Additional protection includes automatic thermal shutdown should the amp overheat. However, with Class-D amp technology, which is highly-efficient, this should never be a problem.

The protection circuits are designed to protect the loudspeakers under reasonable and sensible conditions. Should you choose to ignore the warning signs [e.g. excessive distortion], you can still damage the speaker in the loudspeaker by overdriving it past the point of amplifier clipping.

Such damage is beyond the scope of the warranty.

Limiting

The driver has its own compression circuit which helps protect it from damaging transient peaks.

The compressor is designed to be transparent and is not noticeable under normal operating conditions.

Overexcursion Protection

A subsonic filter circuit just prior to the power amplifier prevents ultra-low frequencies from being amplified. Excessive low-frequency energy can damage the woofer by causing it to “bottom out,” also know as overexcursion, which is equivalent to a mechanical form of clipping.

ABOUT

FW : DRM212 v1.0.29

DSP : DRM212 v111

TEMP : 29˚C / 85˚F

Thermal Protection

All amplifiers produce heat. DRM loudspeakers are designed to be efficient both electrically and thermally.

In the unlikely event of the amplifier overheating, a built-in thermal switch will activate, muting the signal.

When the amplifier has cooled down to a safe operating temperature, the thermal switch resets itself, and the DRM loudspeaker resumes normal operation.

If the thermal switch activates, try turning down the level control a notch or two on the mixing console

(or via the Speaker Control knob) to avoid overheating the amplifier. Be aware that direct sunlight and/or hot stage lights may be the culprit of an amplifier overheating.

18

DRM Professional Powered Loudspeaker Series

AC Power

Be sure the DRM loudspeaker is plugged into an outlet that is able to supply the correct voltage specified for your model. It will continue to operate at lower voltages, but will not reach full power. Be sure the electrical service can supply enough amperage for all the components connected to it.

We recommend that a stiff (robust) supply of AC power be used because the amplifiers place high current demands on the AC line. The more power that is available on the line, the louder the speakers will play and the more peak output power will be available for a cleaner, punchier bass. A suspected problem of “poor bass performance” is often caused by a weak AC supply to the amplifiers.

Never remove the ground pin on the power cord or any other component of the DRM loudspeaker. This is very dangerous.

Placement

WARNING: Installation should only be done by an experienced technician.

Improper installation may result in damage to the equipment, injury or death. Make sure that the loudspeaker is installed in a stable and secure way in order to avoid any conditions that may be dangerous for persons or structures.

DRM loudspeakers are designed to sit on the floor or stage as the main PA or as monitors. They may also be pole-mounted via the built-in socket on the bottom of the cabinet. Be sure the pole is capable of supporting the weight of the loudspeaker. The SPM400 is a great option when using a subwoofer.

These loudspeakers may also be flown via their integrated fly points as detailed on the following pages. Be sure to read the PA-A2 Eyebolt Installation

Instructions, as well.

NEVER attempt to suspend a DRM loudspeaker by its handles.

Care and Maintenance

Your DRM loudspeakers will provide many years of reliable service if you follow these guidelines:

• Avoid exposing the loudspeakers to moisture.

If they are set up outdoors, be sure they are under cover if rain is expected.

• Avoid exposure to extreme cold (below freezing temperatures). If you must operate the loudspeakers in a cold environment, warm up the voice coils slowly by sending a low-level signal through them for about

15 minutes prior to high-power operation.

• Use a dry cloth to clean the cabinets. Only do this when the power is turned off. Avoid getting moisture into any of the openings of the cabinet, particularly where the drivers are located.

Check to make sure that the support surface

(e.g. floor, etc.) has the necessary mechanical characteristics to support the weight of the loudspeaker(s).

When pole-mounting loudspeakers, be sure that they are stabilized and secured from falling over or being accidentally pushed over. Failure to follow these precautions may result in damage to the equipment, personal injury, or death.

The DRM212 and DRM215 have dual angle pole-mounts for optimal coverage. The rear one is a straight angle while the front is angled at a 7˚ downward tilt. Additionaly, these two models may be laid out horizontally as monitors for the band at a 50˚ angle (as seen below).

The Running Man logo is rotatable for when the DRM212 or DRM215 is used as a monitor; you can also rotate it when the DRM315 is flown horizontally!

As with any powered components, protect them from moisture. Avoid installing the loudspeaker in places exposed to harsh weather conditions. If you are setting them up outdoors, make sure they are under cover if you expect rain.

Room Acoustics

DRM loudspeakers are designed to sound fantastic in nearly every application.

But, room acoustics play a crucial role in the overall performance of a sound system. However, the wide high-frequency dispersion of the DRM loudspeakers helps to minimize the problems that typically arise.

Here are some additional placement tips to help overcome some typical room problems that might arise:

• Placing loudspeakers in the corners of a room increases the low frequency output and can cause the sound to be muddy and indistinct.

• Placing loudspeakers against a wall increases the low frequency output, though not as much as corner placement. However, this is a good way to reinforce the low frequencies, if so desired.

• Avoid placing the speakers directly on a hollow stage floor. A hollow stage can resonate at certain frequencies, causing peaks and dips in the frequency response of the room. It is better to place them on a sturdy stand designed to handle the weight of the loudspeaker.

• Position the loudspeakers so the high-frequency drivers are two to four feet above ear level for the audience (making allowances for an audience that may be standing/dancing in the aisles).

High frequencies are highly directional and tend to be absorbed much easier than lower frequencies.

By providing direct line-of-sight from the loudspeakers to the audience, you increase the overall brightness and intelligibility of the sound system.

• Highly reverberant rooms, like many gymnasiums and auditoriums, are a nightmare for sound system intelligibility. Multiple reflections off the hard walls, ceiling, and floor play havoc with the sound. Depending on the situation, you may be able to take some steps to minimize the reflections, such as putting carpeting on the floors, closing draperies to cover large glass windows, or hanging tapestries or other materials on the walls to absorb some of the sound.

However, in most cases, these remedies are not possible or practical. So what do you do? Making the sound system louder generally doesn’t work because the reflections become louder, too.

The best approach is to provide as much direct sound coverage to the audience as possible. The farther away you are from the speaker, the more prominent will be the reflected sound.

Use more speakers strategically placed so they are closer to the back of the audience. If the distance between the front and back speakers is more than about 100 feet, you should use either (1) the internal delay processor via the speaker control knob (see page 15), or (2) use an external delay processor to time-align the sound. (Since sound travels about

1 foot per millisecond, it takes about 1/10 of a second to travel 100 feet.)

Keep in mind that the speaker mode is another great way to compensate for some of these issues. See page

12 for more information.

Rigging

WARNING: Installation should only be done by an experienced technician. Improper installation may result in damage to the equipment, injury or death. Make sure that the loudspeaker is installed in a stable and secure way in order to avoid any conditions that may be dangerous for persons or structures.

WARNING: The cabinet is suitable for rigging via its fly points. NEVER attempt to suspend a DRM loudspeaker by its handle.

The fly points of the DRM212, DRM215 and DRM315 are shown on the previous page while examples of a flown DRM315 are displayed below.

The DRM315 may be flown horizontally or vertically, but the DRM212 and DRM215 may only be flown vertically.

Rigging Design Practices

Rigging a loudspeaker requires determining:

1. The rigging methods and hardware that meet static, shock, dynamic, and any other load requirements for supporting the loudspeaker from structure.

2. The design factor and required WLL (Working

Load Limit) for this support.

We strongly recommend the following rigging practices:

1. Documentation: Thoroughly document the design with detailed drawings and parts lists.

2. Analysis: Have a qualified professional, such as a licensed Professional Engineer, review and approve the design before its implementation.

3. Installation: Have a qualified professional rigger do the installation and inspection.

4. Safety: Use adequate safety precautions and back-up systems.

Rigging Hardware and Accessories

Rigging our loudspeakers will invariably require hardware not supplied by us. Various types of load-rated hardware are available from a variety of third-party sources. There are a number of such companies specializing in manufacturing hardware for designing and installing rigging systems. Each one of these tasks is a discipline in its own right.

Because of the hazardous nature of rigging work and the potential liability, engage companies that specialize in these disciplines to do the work required.

We do offer certain accessory rigging items and some of them may be used with a variety of products. While these accessories are intended to facilitate installation, the wide variety of possible installation conditions and array configurations do not permit us to determine their suitability or load rating for any particular application.

We are not in the business of providing complete rigging systems, either as designers, manufacturers, or installers. It is the responsibility of the installer to provide a properly engineered, load-certified rigging system for supporting the loudspeaker from structure.

DRM loudspeakers may be individually flown using a PA-A2 Eyebolt Kit, part number 0028272.

Rigging Notes

The DRM loudspeaker’s integral mounting points are designed to support only the weight of their own loudspeaker with suitable, external hardware. This means that each DRM loudspeaker must be supported independently of any other DRM loudspeaker and any other loads. At least three rigging points must be used to hang each DRM loudspeaker.

Appendix A: Service Information

If you think your DRM loudspeaker has a problem, please check out the following troubleshooting tips and do your best to confirm the problem. Visit the Support section of our website (www.mackie.com/support) where you will find lots of useful information such as FAQs and other documentation. You may find the answer to the problem without having to part with your loudspeaker.

Noise

• Make sure all connections to the loudspeakers

are good and sound.

• Make sure none of the signal cables are routed near

AC cables, power transformers, or other EMI-inducing

devices.

Troubleshooting

No power

• Our favorite question: Is it plugged in? Make sure

the AC outlet is live [check with a tester or lamp].

• Is there a light dimmer or other SCR-based device

on the same AC circuit as the DRM loudspeaker?

Use an AC line filter or plug the loudspeaker into

a different AC circuit.

• Our next favorite question: Is the power switch on?

If not, try turning it on.

• Make sure the line cord is securely seated in the line

cord socket and plugged all the way into the AC outlet.

• Is the power LED on the front panel illuminated?

If not, make sure the AC outlet is live. If so, refer

to “No sound” below.

Hum

• Try disconnecting the cable connected to the input

jack. If the noise disappears, it could be a “ground

loop,” rather than a problem with the DRM

loudspeaker. Try some of the following troubleshooting

ideas:

• Use balanced connections throughout your

system for the best noise rejection.

• Whenever possible, plug all the audio

equipment’s line cords into outlets which share

a common ground. The distance between

the outlets and the common ground should

be as short as possible.

• The internal AC line fuse may be blown. This is not

a user serviceable part. If you suspect the AC line

fuse is blown, please see the "Repair" section next.

No sound

• Is the level knob for the input source turned all the way

down? Verify that all the volume controls in the system

are properly adjusted. Look at the level meter

to ensure that the mixer is receiving a signal.

Other Issues

• Please email or call Technical Support if you

are having any other issue not listed here:

o mackie.com/support-contact

o 1-800-898-3211

• Is the signal source working? Make sure

the connecting cables are in good repair and securely

connected at both ends. Make sure the output level

control on the mixing console is turned up sufficiently

to drive the inputs of the speaker.

• Make sure the mixer does not have a mute on

or a processor loop engaged. If you find something

like this, make sure the level is turned down before

disengaging the offending switch.

• Has it shut down? Make sure there is at least six

inches of free space behind each DRM loudspeaker.

Poor sound

• Is it loud and distorted? Make sure that you’re not

overdriving a stage in the signal chain. Verify that

all level controls are set properly.

• Is the input connector plugged completely into

the jack? Be sure all connections are secure.
