Introducing the HL400.4, the latest audio amplifier in the HIGH LINE family!
The HL400.4 is designed to deliver exceptional performance with superior audio quality even with its compact size. With 4 channels of amplified outputs and frequency response from 5Hz to 24Khz, it offers flexibility for use in STEREO or BRIDGE.
Ideal for complete audio systems, such as coaxial speakers, triaxial speakers, subwoofers, woofers, drivers or tweeters, it offers the versatility to use a single amplifier.
HD Audio Processing: Enjoy precise, high-fidelity audio reproduction, with well-defined mids and clear highs.
CROSSOVER Controls: The amplifier features CROSSOVER switches, allowing precise frequency adjustments to meet specific system needs.
CH1 & CH2 CHANNELS (MODES):
FLAT: No frequency cuts L.P.F: 90Hz frequency (fixed)
H.P.F: 90Hz frequency (fixed)
CH3 & CH4 CHANNELS (MODES):
FLAT: No frequency cuts
L.P.F: Frequency from 30Hz to 75Hz (variable) + 14dB Bass Boost (Output with low frequency adjustment, ideal for use with SUBWOOFER)
H.P.F: 90Hz frequency (fixed)
BRIDGE mode for STRONG BASS: By joining two channels, the amplifier operates in BRIDGE mode, doubling the power available to power SUBWOOFERS or other demanding components.
