Speaker Placement and Polarity

The cabinets in the following example configurations are in a close-proximity coplanar orientation, unless otherwise stated. Placing the mid-hi speaker more than 5 feet from the subwoofer may require setting the speakers to opposite polarities to compensate for the propagation delay between them.

In a coplanar orientation, externally amplified Meyer subwoofers require the opposite polarity setting to all Meyer self-powered speakers.

We recommend using the Meyer SIM® System II Sound Analyzer and CP-10 Parametric Equalizer to

• assist the process of configuring and placing

speakers in a system;

• measure propagation delays to set the correct

polarity between speakers;

• measure and equalize variations in frequency

response caused by the acoustical environment

Meyer Speaker Types

The following Meyer speakers will be mentioned in the example applications.

MSL-4:Self-powered mid-hi speaker

DS-2P:Self-powered mid-bass speaker

650-P, PSW-2,

PSW-4:Self-powered subwoofers

650-R2, MSW-2,

USW-1:Externally amplified subwoofers

The self-powered speakers listed above have a loop connection to send the input signal to another speaker.

CQ and 650-P

The CQ is particularly well matched with the 650-P and also performs efficiently with the PSW-2 and PSW-4. Due to the overlap in frequency response between the CQ and the subwoofer, the system frequency response contains a rise in the range 40–120 Hz. It is important to emphasize that the speakers are in phase in this region. The rise can be corrected using the Meyer CP-10 Parametric Equalizer, if desired.

and the placement and interaction of speakers.

The LD-1A Line Driver

We recommend using the Meyer LD-1A Line Driver to integrate different types of Meyer self-powered speakers into a full-range system. The LD-1A maintains

signal integrity for long cable paths, has two channels equipped to control a main system, and six auxiliary channels for down-fill, front-fill, and delay systems. The LD-1A provides these useful functions:

•The Lo Cut switch activates a high-pass filter (160 Hz, –12 dB/oct, Q = 0.8) that performs a crossover function for the Mid-Hi output.

•The Array EQ switch activates a filter (6 dB cut at 220 Hz, 0.6 octave bandwidth) to equalize groups of 3 to 5 horizontally arrayed MSL-4s.

•The DS-2 & Sub Crossover switch activates a crossover network that sends frequencies below 80 Hz to the Sub output, and above 80 Hz to the DS-2 output. With the switch out, a full-range signal is sent to the DS-2 and Sub outputs.

•The DS-2φ and Sub φ switches toggle the polarity for the DS-2 and Sub outputs.

•The Mid-Hi, DS-2, and Sub outputs each have their own gain control and mute switch.

Set the CQ and 650-P to the same polarity.

CQ and 650-R2

Although it is preferable to use the CQ in a completely self-powered system, excellent results can still be achieved using the 650-R2, USW-1, and MSW-2.
