Frequently Asked Questions - I8SCMF+ Atlas Sound
What is the recommended amplifier power for the I8SCMF+?
An amplifier delivering 150 to 300 watts RMS into 8 ohms is recommended. Ensure the amplifier is stable at 8 ohms and does not exceed the speaker's program power rating.
Can the I8SCMF+ be used outdoors?
Yes, it has an IP55 weather rating, making it suitable for covered outdoor areas. Avoid direct exposure to water jets or submersion.
How do I wire the speaker for 70V/100V line systems?
If using the optional transformer, connect the amplifier output to the transformer's input terminals and select the desired tap (e.g., 8, 16, 32, 64 watts) via the selector switch. For 8-ohm operation, bypass the transformer.
What is the coverage pattern of this speaker?
The rotatable waveguide provides 90° horizontal by 60° vertical coverage. Rotate the waveguide 90° for vertical dispersion patterns.
Does the I8SCMF+ include a mounting bracket?
Yes, a sturdy metal surface-mount bracket is included. It allows tilt and swivel adjustments for precise aiming.
What is the frequency response of this speaker?
