Lend Me Your Ears

Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in suscepti-

bility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufﬁciently intense noise for a period of time. The U.S. Government’s Occupational Safety and Health Administration (OSHA) has speciﬁed the permissible noise level exposures shown in this chart.

According to OSHA, any exposure in excess of these permissible limits could result in some hearing loss. To ensure against potentially dangerous exposure to high sound-pressure levels, it is recommend ed that all persons exposed to equipment capable of producing these levels use hearing protectors while this unit is in operation. Ear plugs or protectors in the ear canals or over the ears must be worn when operating this ampliﬁcation system in order to prevent a permanent hearing loss if exposure is in excess of the limits set forth here.

INTRODUCTION

Thank you for choosing Mackie’s active sound reinforcement speaker systems.

The SWA1801z is a high-output active subwoofer system. It features a high-precision 18" transducer combined with application-speciﬁc ampliﬁer technology. The system is composed of a single, compact subwoofer cabinet with built-in control and ampliﬁer electronics.

Connecting and setting up the SWA1801z is a breeze. It accepts a stereo or mono line-level signal via female XLR input jacks. Male XLR Thru jacks are provided for daisy-chaining the signal to additional SWA1801z cabinets. The built-in crossover separates the low frequencies from the high frequencies, and routes the high frequencies to the male XLR high-pass output jacks. Connect these to the inputs of full-range active speakers such as the Mackie SA1521z, or to an ampliﬁer powering a pair of passive speakers such as a

The SWA1801z

can produce a maximum

SPL of 135 dB @ 1m

combination of the Mackie M•1400i and C300z. A Phase

switch gives you the option of reversing the polarity of the signal to the subwoofer by 180º. A Subwoofer Level control allows you to adjust the balance between the subwoofer and the full-range speakers.

The built-in ampliﬁer produces 800 watts of continuous power. The ampliﬁer module sits on a heatsink that eliminates the need for fans, dramatically extending life expectancy, and eliminating maintenance cycles. A tremendous beneﬁt of having the ampliﬁer located within the subwoofer cabinet is that the SWA1801z functions as a system, optimizing acoustic, electronic, and mechanical designs to achieve the highest level of performance and value.

The cabinet is constructed with 15 mm thick multilayered birch plywood. Carrying handles are integrated into each side for easy loading, and casters are attached to the rear for easy transport.

REAR PANEL DESCRIPTION

POWER Switch

Use this switch to turn the SWA1801z on and off. Make sure the signal source’s level control is turned down before you turn it on.

AC Receptacle

This is where you connect the AC linecord provide AC power to the SWA1801z’s built-in power ampliﬁers. Plug the linecord into an AC socket properly conﬁgured for your particular model.

LIMIT Indicator

The SWA1801z has a built-in limiter that prevents the ampliﬁer outputs from overdriving the

LIMIT

transducers. The limiter is activated. It’s okay for the

indicator lights when the

LIMIT

indica-

tor to blink occasionally, but if it blinks frequently or lights continuously, turn down the level control

LIMIT

until the

indicator only blinks occasionally.

SIGNAL Present Indicator

This LED illuminates whenever there is a signal present at the

FULL RANGE INPUT

con-

nector on the rear panel.

THERMAL Indicator

The SWA1801z has a thermal protection circuit that monitors the internal temperature of the ampliﬁers and heatsink. If the internal temperature should exceed a safe operating level, this indicator lights and the signal is muted to allow the ampliﬁer to cool. When the temperature cools to a safe level once again, the thermal protection circuit deactivates and normal operation resumes.

Activation of the thermal protection

Note:

cuit is an indication that you should take steps to avoid continued thermal problems. See “Thermal Considerations” on page 7.

When the the linecord is connected to an active AC power supply, this indicator lights green to let you know that you’re ready to rock and roll. The cool blue LED on the front of the cabinet works in the same way.

FULL RANGE INPUT

These are female XLR-type connectors that accept a balanced line-level signal from a mixing console or other signal source.

THRU (FULL RANGE OUTPUT)

These are male XLR-type connectors that produce exactly the same signal that is connected

FULL RANGE INPUT

to the

jack. Use it to daisychain several SWA1801z's together off the same signal source.

HIGH PASS (MID/HIGH FREQ) OUTPUT

These are male XLR-type connectors that produce the frequencies above 120Hz. Connect these to a pair of full-range active speakers or to an amplifer/passive speaker combination. The SWA1801z reproduces the frequencies below 120Hz.

SUBWOOFER LEVEL Control

This adjusts the subwoofer level. The center detent position provides 15 dB of headroom with

a nominal +4 dBu input signal. Use this as a

starting point for setting the balance between the subwoofer and the main speakers.

PHASE

This switch reverses the polarity of the subwoofer output. Depending on the placement of the SWA1801z subwoofer relative to the full-range speakers, you may get a better low-frequency response in the room if you reverse the polarity of the subwoofer’s signal. Experiment with this switch to determine which position sounds best.
