TASCAM AV-452, PRESENTATION MIXER/AMPLIFIER
	AV-452 Presentation Mixer/Amplifier
Main features
Four microphone channels With phantom power, 60-mm faders, gain, mute and 3-band EQ A/V channel with video switching Inputs for two audio sources and three audio/video sources 60-mm faders, gain, dim and 3-band EQ Record monitor control for dubbing between sources Motorized room volume control Built-in digital power amplifier 100 Watts per side at 8 Ohms, operates from 4-16 Ohms Headphone output with level control 100 mW per side at 68 Ohms, 6.3-mm TRS connector Universal learning remote control included Buttons for AV-452, projector power and A/V components Capable of projector switching AV-452 unit learns IR codes to be transmitted to projector for switching between input sources Capable of bi-directional control Relay control port for direct connection of buttons and LEDs Serial port (RS-232, RS-422 or RS-485) for connection of a media control system Parallel port Integrates with building communication systems 12V/24V/70V constant voltage input with mute and gate EMG input mutes AV-452 when emergency alarm is detected Room for growth & enhanced operation Balanced line output for using external amplifiers Balanced cascade input for adding more sources via a second AV-452 or other mixer or for driving another power amplifier Microphone group insert for dynamic processing or splitting signals Meeting record output for documenting meeting minutes
