a Microphone ON-Off Controller With
Integrated Stereo Headphone Amplifier and
Line Level IFB Talkback Circuitry

The ideal solution for remote broadcasts requiring IFB talkback to the studio, and works in conjunction with other Audio-Pod modules and Power Supply

The Audio-Pod Plus module features microphone On-Off control with an integrated stereo headphone amplifier, and a line level IFB output that is activated when the "Talk-Back" button is pushed which also simultaneously and seamlessly mutes the main microphone feed. The Audio-Pod Plus module includes a high quality-low noise mic pre-amplifier with switchable phantom power. One Audio-Pod Power Supply will power up to four Audio-Pod modules, and any combination of Audio-Pod module types or options may be combined using the same Power Supply. 10 foot power supply cables and trimpot adjustment tool are supplied.

Table-top brackets for mounting the Audio-Pod Plus module at an angle are available.

  • The optional Mic pre-amplifier portion includes the following features:
    • High quality, low noise mic preamp circuitry with rear panel variable gain control, output adjustable from mic to line level
    • Phantom power with rear panel switch and LED indicator
    • Precision metal film resistors used throughout audio chain for low noise

    The microprocessor controlled Mic ON-OFF control portion includes the following features:
    • Large LED differentially lighted Mic-On and Mic-Off long life silent reed type push buttons
    • Cough-mute function integrated with Mic-On button (Operational with local control mode enabled only)
  • • Control buttons are located on the top surface so you don't have to chase the module all over the desk
    • Local Mic On-Off feature may be disabled and controlled remotely
    • Remote control of Mic On-Off function with a logic low or contact closure may be accomplished with either local control enabled or disabled
    • XLR connectors for Mic in and out (balanced) as well as Eurostyle screw terminal termination of Mic out connection
    • Solid State Relay output drive voltage provided, continuous or flashing, (option) to drive a DME Solid State Relay Pack or customers own solid state relay for ON-AIR lamps or for external LED indicator (multiple Audio-Pod SSR outputs may be connected in parallel to operate one SSR in the constant SSR output mode only)

The IFB "Talk-Back" circuit includes the following features:
• Large LED lighted long life silent reed type push button
• Simultaneous and seamless muting of the main microphone feed when the "Talk-Back" button is pushed
• Line level 600 ohm balanced IFB output

The integrated stereo headphone amplifier section includes the following features:
• Voltage Controlled Amplifier (VCA) circuitry employed (no “dirty” pots)
• Power Op-Amp headphone output providing both the power and P-P voltage required to drive headsets ranging from 8 to 600 ohms
• Rear panel output phase switch (0/180 degrees) to address bone conduction cancellation issues often experienced by users
• ESD protected ¼” and 3.5mm stereo headphone output jacks on the front panel
• Rear panel "maximum headphone gain set control" to restrict the maximum headset output to prevent possible hearing damage and liability issue avoidance
• Single ended L&R inputs on rear panel 3.5mm stereo jack for quick connect and disconnect
• Precision metal film resistors used throughout the audio chain for low noise
