Paradigm 270, OM-121 Placement Options for ‘SM’ Models, Speaker Impedance with Multiple Speakers

Placement Options for ‘SM’ Models

Your Stylus® ‘SM’ speaker offers two options for connection:

•Stereo Input: Wide dispersion “Left plus Right” channel sound from a single speaker.

•Mono Input: Very wide dispersion stereo sound from two speakers, one for the left, one for the right.

With their Dual-Directional Soundfield™, ‘SM’ speakers provide wider than normal dispersion, allowing them to be used in a variety of outdoor applications:

Single Speaker, Wide Dispersion “Left plus Right” Channel Sound (Stereo Input) (Fig. 2a)

Ideal in small areas less suited to a stereo pair of speakers or where a single speaker is the preferred choice. The speaker is connected to both Left and Right amplifier channels. Place the speaker so that it is “aimed” toward the listening area.

Two Speakers, Very Wide Dispersion Stereo Sound (Mono Input) (Fig. 2b)

Ideal for stereo coverage in small to medium sized areas. One speaker is connected to the Left amplifier channel and the other to the Right channel (each wired for Mono). Place speakers about 12 – 16 feet apart to achieve good stereo imaging throughout your listening area.

Multiple Speakers, Distributed “Left plus Right” Channel Sound (Stereo Input) (Fig. 2c)

In larger areas, multiple speakers (each wired for “Left plus Right” channel sound) may be used to eliminate the sound imbalances that occur with stereo sound as people move around, or are seated closer to one speaker than the other.

Multiple Speakers, Ultra-Wide Stereo Coverage (Mono Input) (Fig. 2d)

In larger areas multiple speakers (each wired for Mono) can be used to provide ultra-wide stereo coverage and broader imaging.

Speaker Impedance with Multiple Speakers

If you are planning to use multiple speakers, first determine the number of speakers your amplifier is capable of driving safely. Check your amplifier’s specifications to determine minimum safe speaker impedance load (in ohms).

The MINIMUM load impedance of one Stylus® speaker is:

• 8 ohms per channel

The MINIMUM load impedance of one Stylus® ‘SM’ speaker is:

• 8 ohms per channel when wired for Stereo Input

• 4 ohms per speaker when wired for Mono Input

	Each additional speaker you connect will drop nominal impedance by half.
	We strongly recommend using a Paradigm® VC-150 volume control when
	connecting more than two speakers. See “Using a Volume Control,” or see
	dealer for more information.
