SM2-400 / SM2-1000 / SM2-1200 / 2-CHANNEL AMPLIFIER APPLICATIONS

Stereo high pass with mono low-pass in a 2 way active, or bi-amplified system

In this application we will use a 2 channel amplifier for the high frequencies, and a second one for the low frequencies, or mono sub bass. Please consult the speaker specifications to determine maximum amplifier power requirements.

Interconnect cable checklist:

Connect the inputs of the HIGHS amplifier to a Radio/CD with good quality RCA cables. Connect the LINE OUT of the HIGHS amplifier to the inputs of the BASS amplifier with a stereo RCA to RCA cable.

Mono bass woofer wiring:

Connect the mono speaker positive terminal to the RIGHT +, and its negative terminal to LEFT -.

Switch setting checklist:

-Highs amplifier: X-OVER switch in the HPF position.

-Lows amplifier: X-OVER switch in the LPF position.

Crossover frequency control checklist:

Highs amplifier:

-HI PASS: 100 Hz

-LOW PASS: N/A

Lows amplifier:

-HI PASS (Subsonic filter): 10 Hz to 40 Hz

-LOW PASS: 100 Hz

Please note that these frequency points are suggestions only. Refer to the loudspeaker manufacturer specifications and the section “Setting up systems after installation for best performance”

Level control checklist:

-Refer to the section “Setting up systems after installation for best performance”

Minimum final loudspeaker impedances:

-2-Ohms per channel stereo.
