Owner's Manual

Painting the Speakers

The injection molded, polypropylene, talc impregnated cabinets can be painted to match your décor. You should prime the cabinet with

two coats of a product such as Krylon

sure to use appropriate exterior house paint for outdoor applications).

Remove the grilles and brackets.

Mask the speaker components and input terminal area with newspaper and masking tape.

Apply two thin primer coats to the speaker cabinets and knobs. (The brackets do not require a primer coat.)

After the primer coats are completely dry, paint the cabinets, brackets and knobs. Be careful not to paint the input terminals!

Painting the Grilles

If you choose to pain the grilles, you must remove the grille before painting.

SM42T: Using a paper clip bent into a "hook" shape, insert it into a grille near the corner and pull the grille away from the cabinet.

SM52T: Using a paper clip bent into a "hook" shape, insert it into a grille near the corner and pull the grille away from the cabinet.

SM82T: Remove all screws around the outside of the grille to remove the grille from the cabinet.

Apply two thin coats of paint (primer is not required), be careful not to let the paint clog the holes in the grilles.

8Ω Connections

The SM42T, SM52T, and SM82T loudspeakers include an 8Ω switch position.

CAUTION: Do not set switch to 8Ω position when speakers are wired in 70.7V / 100V Systems.

The SM42T, SM52T, and SM82T include a two pole barrier strip housed by a weather-resistant cover. The barrier strip is designed to

accept either spade connectors or bare wire.

Amplifier limitations will dictate how many SM42T / SM52T / SM82T speakers may be connected. Most consumer amplifiers are rated

to operate at a 4Ω minimum output impedance per channel (Check the back panel of the amplifier or the amplifier owners manual to

verify). With this arrangement, two SM Series speakers may be connected in parallel to each channel of the amplifier (two 8Ω speakers

per channel = a 4Ω load). (See Figure 1)

Be sure to use good quality, un-shielded twisted pair speaker cable to connect the amplifier to the speaker(s) (#14AWG for runs <80',

#12AWG for runs >80'). Standard ZIP style speaker cable may also be used if twisted pair cable is not available.

DO NOT USE SHIELDED INSTRUMENT STYLE (Guitar) CABLES TO CONNECT SPEAKERS.

When making the connections, be sure to maintain proper polarity between speakers. (Red wire to red (or +) terminal - black wire to

black (or –) terminal where applicable). Atlas Sound offers several auto-former speaker selectors (Atlas Sound ASL series) and volume

controls (Whisper Touch series) that will allow you to connect multiple pairs (up to 6) of 8Ω loudspeakers without damaging your ampli-

fier. Contact your dealer or factory for details.

Sandable Spray Primer #1318. You may use oil or water based house paint or spray paint. (Be
