Product Highlights
- Class a/b topology - class ‘a’ amplifiers have enormous amount of current flowing through its output transistors with no audio signal. class ‘b’ amplifiers have no current flowing through its outputs with no audio signal
- Variable gain control - the gain control is not for adjusting volume. it simply adjusts the amount of signal that is coming from your receiver and going to your amplifier
- Fixed high-pass crossover - speakers reproduce sound based on high, low or mid-range frequencies. the high-pass crossover gears specifically towards “highs” such as all size speakers including mid ranges and tweeters
- Specs - dimensions: 10.72” x 10.44” x 2.25”, weight: 5.80 lbs., speaker impedance: 2 to 8 ohm, thd @ rms output: 0.01%, s/n ratio: 102 db, frequency response: 9 hz to 50 khz, fuse quantity: 2 25 amp ato blade
