The CX3400 provides two modes of operation: 3-way stereo, for left and right lows (woofers), mids and highs (tweeters); and 4-way mono, for lows, low-mids, high-mids and highs. In either mode, you have the option of normal (left and right), or summed-mono low-frequency output. Adjustable time delays (up to two milliseconds) are also provided, so that the sound coming from the various transducers arrives at the listener in-phase and at the same time.
By using 1% metal film resistors, along with other extremely tight-tolerance components, the CX3400 is able to guarantee surgically precise frequency selection with incredibly low thermal noise. State-of-the-art, ultra low-noise op amps ensure super-quiet operation. CX3400's elegant LED matrix shows at a glance which operation mode is selected and which controls are active.
All of the inputs and outputs accept balanced and unbalanced XLR connections. The inputs feature 25 Hz Low Cut filters for low-frequency driver protection. Mute and phase invert switches are provided for each frequency range, making troubleshooting an entire loudspeaker system a breeze.
