    Galaxy Audio CM-140 reviews

    CM-140 CHECK MATE - SPL Meter is rated 4.3 out of 5 by 3.
    Rated 4 out of 5 by from Display is not backlit I selected this model based on its features and the backlit display. Contrary to the product description, the display is not backlit. I am not happy about that, but the meter seems to work well otherwise

    Rated 4 out of 5 by from A very good basic SPL meter I used this product to equalize the SPL for my Home Theater surround system. It has a wide sensitivity range from 32db at the low end to 130db at the loud end. At very low frequencies of the audio spectrum (40 - 50 Hz) it did not appear to the be responsive. Some more documentation about what to expect and how to decide if it was functioning correctly would be appreciated. However, calling the support number got a real person who then passed me on to technical support person.
