4x1 Audio Switching with Voice Lift Mixing
Audio Products Group
The IT-AS411 Series Audio Switchers are 4x1 audio switchers that have an extra mic/line level input for a voice lift system or direct microphone input. All models have four switched program audio inputs and an independent mic or line level input that is summed (mixed) with the selected active program audio.
FEATURES
All models have balanced or unbalanced input and output capability. DIP switches are provided to set the voice input level to mic or line, adjust microphone sensitivity, set phantom power and select mono or stereo operation. They also have adjustable volume control buttons and mute for both the program audio and voice inputs. Each individual program audio trim (gain), program audio input select, muting and volume control can be executed locally by front panel pushbuttons, muting by external dry contact closure and additional commands via RS-232 serial control. On board LED’s monitor; program, input select, volume level and mute status.
• Terminals for remote muting of voice and/or program audio via dry contact closure
The IT-A411-25M70 features a 25W mono internal audio amplifier to drive either a 4 to 8 ohms speaker or a 70V line output, preamp out.
• Mic / line level voice lift input • Program audio / voice lift mixing • Program audio inputs and outputs • Serial control with serial pass-through
• On board LED’s monitor; input select, volume level and muting status • Current limited remote LED output terminal for program audio and voice (mute) status • Integrated audio amplifiers on A25-M70 and A25-S8 models • Program audio trim (gain) • Preamplifier output DVD/BLU-RAY
