INTEGRAL-A1604 is a quad channel, 2U, high efficiency class D amplifier intended for permanent installation use. It is equipped with switching universal mains power supply and auto-standby functionality when no signal presence is detected providing energy savings.
The amplifier delivers 4x400W at 4ohm and can be used in bridge mode for high impedance 100V/70V lines (providing 2x800W of total power). Front LEDs provide information about signal presence, limiters and protection status. At the rear panel the user can configure the stereo / bridge mode and engage an 80Hz 12dB/oct order High Pass filter.
The sober and elegant design together with the euro-block type connectors and energy savings makes it perfect for permanent installations.
