INTRODUCTION

The Cabinet

Thank you for choosing a Mackie compact active PA

system for your sound reinforcement applications.

The SRM150 is an active PA system that provides a built-in mixer, high sound pressure levels, and is designed to give you the best performance of any compact PA system in its class and price range.

Our design goal was to build a compact PA system with:

1. High precision, high output, and accurate playback.

2. Controlled, smooth dispersion of mid and high

frequencies.

3. Ultra-clean, high-headroom mic preamps.

4. High-output Class-D ampliﬁcation.

5. Onboard Mackie mixer with 3-band EQ.

Through the combined resources of our top-notch mechanical and analog engineers, we were able to achieve our design goals in every aspect. The result is a sound reinforcement PA system equally at home in a concert setting, in the studio, or impromptu concerts on the studio roof.

The Transducer

The SRM150 active loudspeaker features a full-range

5.25-inch neodymium driver.

Power Amplier

Each SRM150 includes a Class-D power ampliﬁer capable of producing 150 watts peak before clipping.

The ampliﬁer includes the following features:

• The amplier produces up to 100 watts rms continuous

before clipping (150 watts peak).

• A built-in limiter acts when the input signal is large

enough to cause clipping, distortion, and excessive voice coil heat. The limiter will automatically decrease the signal going to the ampliﬁer to a safe level.

Warning: Although the ampliﬁer has a limiter protection circuit, you must still make sure you don’t overdrive the ampliﬁer. If you hear any distortion, turn down the input (MIC/LINE) gain control, or turn down the MAIN LEVEL control.

The SRM150 cabinet was designed with the same material as our SRM350 and SRM450 loudspeakers, the strongest molded composite cabinet on the planet. It has an insert in the bottom for mic stand mounting (using the mic stand adapter included with your SRM150), and a threaded insert in the top for mounting a microphone boom (using the included boom extender).

Its light weight and durable ﬁnish make it ideal for portable sound system use. In addition, the unique design of the cabinet makes it easy to use as a ﬂoor wedge for stage monitor applications.

The Active Advantage

There are a number of advantages to using an active speaker system over a passive loudspeaker:

• The ampliers are designed specically for the speaker

load impedance. There is no guesswork as to what load the ampliﬁer has to drive, so it can provide maximum acoustic output from the speaker, yet minimize the danger of speaker damage due to overdriving a lesser ampliﬁer.

• The connecting wires between the amplier output and

the driver is kept to a minimum, so the damping factor of the ampliﬁer isn’t compromised by the resistance of long speaker cables. In addition, all the power from the ampliﬁer is transferred directly to the driver with no speaker cable losses.

• The presence of active circuits within the speaker

cabinet allow the designer to add on extra details, such as a high quality mic/line input section.

In short, all the complex interconnected components in the system are designed to work in harmony with each other to produce the best possible sound.

1. Start with the following settings on the front of the SRM150:

• MAIN LEVEL [6] control down.

• PHANTOM POWER [5] switch out (unless you are

using condenser microphones).

• INSTRUMENT [4] switch out (unless you have an

electric guitar connected to channel 1).

• Channels 1-3 gain [3] controls down.

• EQ [7] controls centered.

And on the rear panel:

• Turn the POWER [8] switch off (down).

• MIC/LINE [12] switch out.

WARNING: Turn the MAIN LEVEL

[6]control down (counterclockwise)

before every use. If not, you could be in for a startling surprise, especially if the last time you used it was with a microphone and now you want to connect a line-level source.

2. Connect the output from your signal source (mixing console, microphone, preamp, or other mic- or line-

level source) directly to the MIC/LINE [1] combo

connector on the front of the SRM150. It accepts balanced line-level signals from mixers, preampliﬁers, CD players, tape decks, etc., and accepts direct

connections from microphones. Channel 3 has ste-

reo RCA jacks [2] specically for a stereo line-level

input from a tape deck or CD player.

3. Connect the supplied AC power cord to the AC

power receptacle [10] on the back of the SRM150.

Plug the other end into an AC outlet properly conﬁgured with the correct voltage for your particular model. (The SRM150 has a universal power supply that accepts an AC mains voltage ranging from 100V to 240 V.)

4. Turn on your signal source. Make sure its Master Volume control (if it has one) is turned all the way down.

5. Turn on the SRM150 POWER [8] switch.

6. Start the signal source, whether it be speaking into a microphone, playing a guitar, or starting a CD player. Adjust any volume controls on the signal source for normal operation.

7. Turn up the MAIN LEVEL [6] control about halfway

(12 o’clock).

8. Slowly turn up the gain [3] controls for the input

channels until the desired volume is reached.

9. If it gets really loud, really fast, try turning down the MAIN LEVEL control (or the input source volume control, if it has one).

If it doesn’t get very loud, even with the input chan-

nel gain control all the way up, try turning up the MAIN LEVEL control (or the input source volume control, if it has one).

10. If there is no sound, always turn down the SRM150 MAIN LEVEL control before investigating. There may be a mixer or preampliﬁer mute or tape switch engaged, or a mic switch off.
