Whirlwind THS 5 Talkback Headphone Box

The Whirlwind THS 5 Talkback Headphone Box is a top - notch audio device. It comes with both main and talkback microphone outputs. There's a latching Mic On/Off switch that connects the signal to the Mic Out. A red light lights up when the Mic Out is active and can be turned off using the cough and talkback switches. It offers two types of onboard condenser microphone power, allowing for smooth switching when talkback is engaged. A recessed three - way switch lets you choose between phantom or 'T' power, preventing accidental shut - off. The momentary Cough switch mutes both the Mic Out and the talkback out when pressed. The momentary Talkback switch links the mic to the talkback output and mutes the Mic Out. The announcer's microphone goes through a preamp and line driver, sending the signal to the talkback output at line level. There's a level control for precise adjustment of the talkback audio. The Talkback switch glows green when depressed. It has two balanced line - level headphone inputs on individual female XLR connectors. Front - panel volume controls and pan pots let you separately adjust the left and right ear levels. There's also a third set of volume and pan pots to add the announcer's microphone to the headphone mix. A master headphone volume pot adjusts the overall mix in both ears at once. It can drive headphones with impedances from 30 to 600 Ohms to full volume. Power is provided by a 12 VAC power adapter (model # PS12AC1A) included with the unit. Key features include two balanced line - level inputs with individual volume and pan controls, announcer mic mix to headphones with volume and pan controls, master headphone volume adjustment, passive Mic Out for on - air reliability with dynamic mics, active line - level Talkback Out with level adjustment, Mic On, Cough and Talkback switches for control, 1/4” TRS or 3.5mm headphone jacks, and an included PS12AC1A power adapter.

Using the Whirlwind THS 5 Talkback Headphone Box is easy. First, connect the 12 VAC power adapter (model # PS12AC1A) that comes with the unit to power it up. Plug your headphones into either the 1/4” TRS or 3.5mm jacks. For microphone connections, use the balanced line - level inputs on the individual female XLR connectors. Adjust the volume and pan controls on the front panel to set the sound levels for your left and right ears. You can also use the third set of volume and pan pots to add the announcer's microphone to the headphone mix, and use the master headphone volume pot to adjust the overall sound. When it comes to the microphone functions, use the Mic On/Off switch to connect the signal to the Mic Out. The red light shows when the Mic Out is live. Press the Cough switch to mute both the Mic Out and talkback out. The Talkback switch connects the mic to the talkback output and mutes the Mic Out, and it glows green when pressed. For the microphone power, use the three - way switch to choose between phantom or 'T' power. Be careful not to accidentally turn it off as the switch is recessed.
