PARALLEL CONNECTION WIRING

Bi-Amplication / Tri-Amplication

The MX Series two way speakers feature a selectable bi-amp mode (two separate amplifier
channels for low frequency and high frequency signals to the woofer and high frequency
driver of each speaker enclosure). This requires an external active crossover network to
provide a low and high frequency line level output to dedicated low and high frequency
amplifiers for proper processing of the low/high frequency portions of the audio signal. Use
with a separate subwoofer will allow for system tri-amp applications (Separate amplifier
channels for low frequency signals to the subwoofer(s), with separate mid-range frequency
and high frequency amp channels for the mid range drivers and high frequency drivers of
each two way speaker enclosure).

To obtain the best sounding setting for the performance environment and related mid range
and high frequency speakers, consult the manufacturer's operating instructions for the
active crossover and amplifiers that are in use.

OPERATING MANUAL AND USER GUIDE

23

The MX Series subwoofers provide extended high power, low frequency enhancement for

two way and three way sound systems. When combined with the MX Series of two way

enclosures, optimum two and three way system configurations become available.

Of the three MX subwoofer models, only the MX-118B band pass subwoofer enclosure

does not require the use of a crossover. The MX-F18B and MX-218B subwoofers require

an external active crossover network to provide a low frequency, line level output to the

dedicated subwoofer amplifier for proper processing of the low frequency portion of the

audio signal. It is not recommended that full range signals be sent to the MX-F18B and

MX-218B subwoofers. For details, consult the manufacturer's operating instructions for the

active crossover and amplifiers that are in use.

Parallel connections to additional enclosures will result in decreased impedance loads

on the amplifier. To prevent amplifier damage, be aware of cabinet impedances and the

limitations of the amplifier in use before connecting additional speaker cabinets.

Two 8 ohm speaker cabinets, connected in parallel, provide a 4 ohm load to the amplifier.

Four 8 ohm speaker cabinets provide a 2 ohm load to the amplifier, which can be too

low for some amplifiers and can result in decreased performance and overheating of the

amplifier.

(For quick setup of subwoofer enclosures)

- Make all initial connections with the power switches OFF on all equipment.

- Check that all master volumes, levels, or gain controls on all equipment are turned all the

way down.

- Connect the line-level outputs from the system mixer to the inputs of the electronic

crossover units. Connect the appropriate outputs of the crossover units to the appropriate

inputs of the high, mid and low frequency system power amplifiers.

- Connect the appropriate Speaker Output from the high-mid frequency power amplifiers

to the INPUT connectors on the full range or two-way speakers.

- Connect the appropriate Speaker Output from the low frequency power amplifiers to the

INPUT connectors on the MX Series subwoofers using appropriate speaker cables.

- Turn on the mixing console (or other signal source).

- With the level controls all the way down, turn on the amplifier.

- Send a signal source through the mixer, such as a microphone or instrument. Gradually

adjust the volume controls on the mixer and amplifier accordingly.

The MX-118B consists of a heavy duty custom 18 low frequency driver in a sturdy and

portable bandpass enclosure optimally tuned for extended low frequency response. Where

significant extension of low frequency output of a system is required, the addition of one

or more MX-118B subwoofers will provide high output low frequency enhancement to the

overall system.

The MX-118B's bandpass enclosure design provides for uniform low frequency reproduction

without the need for a crossover.

For demanding, high output applications, it is recommended that each MX-118B be powered

with a dedicated, high powered amplifier channel. The MX-118B rear panel connector plate

provides input connections from the output of the amplifier via dual NL-4 Speakon type

connectors that are located on the rear mounted input plate and allow for parallel through

connections to additional enclosures. (See Specifications on page 29)

MX-F18B Folded Horn Subwoofer

The MX-F18B is a passive, single 18" folded horn subwoofer in a surprisingly portable and

easily moveable enclosure. Where significant extension of low frequency output of a sound

system is required, the addition of one or more MX-F18B subwoofers will provide high

output low frequency enhancement to the overall sound system. The MX-F18B is designed to

work with an external active crossover unit.

For demanding high output applications, it is recommended that each MX-F18B be powered

with a dedicated high powered amplifier channel. If a variable low pass control is available

on the active crossover unit being used, it may take some experimentation with different

settings of this control to find the best sounding setting for the particular performance

environment.

The MX-F18B input connections from the output of the amplifier are made via NL-4 Speakon

type connectors that are located on the rear mounted input plate. NL-4 pins1+ /1- are used

for input and parrallel through connections. (See Specifications on page 33)

MX-218B Horn-Loaded Subwoofer

Where significant extension of low frequency output of a sound system is required, the

addition of one or more MX-218B subwoofers will provide high output, low frequency

enhancement to the overall system. The MX-218B is designed to work with an external,

active crossover unit. For demanding, high output applications, it is recommended that

each MX-218B be powered with a dedicated, high powered amplifier channel or an amp

in bridged-mono mode. If a variable low pass filter is available on the active crossover unit

being used, it may take some experimentation with different settings of this control to find

the best so unding settin g for the particular pe rformance environme nt. Consult the

instructions for the electronic crossover being used for details.

Connections:

The MX-218B input connections from the output of the amplifier are via dual NL-4

Speakon® type connectors that are located on the rear mounted input plate. The MX-

218B can be used in a switchable 4 ohm/parallel driver configuration or a discrete, dual

8 ohm driver "DISCRETE"mode that allows a separate amplifier to drive each speaker

independently at 8 ohms each. In PARALLEL mode NL-4 connections 1+/1- are used. In

DISCRETE mode, connections 1+/1- and 2+/2- are used for each driver.
