CONNECTIONS AND POWER

The UT Twin87 requires 2 things in order to properly function: a 3-pin XLR cable, and 48V phantom power. Engage 48V phantom power on your device. If your device does not provide 48V phantom power, an external, dedicated power supply will be required for operation.

HARDWARE CONTROLS
Pattern select – omnidirectional, cardioid, and figure of eight.
HPF – gradual slope rumble filter tuned for voice broadcast, 12 dB down at 80hZ Modern/Vintage – This switch allows the user a choice between the earliest 87-style circuit and the more modern reproductions. -10dB pad – attenuates amplifier section by 10dB to provide greater headroom for loud sources.

Using the Vintage/Modern Modes.
When Vintage/Modern modes are changed, the UT Twin87 will require roughly 10 seconds to morph between sounds. This is normal in all operations,
as the circuitry makes significant configuration changes in order to replicate both variations in extreme detail.
The modern setting yields a slightly hotter, brighter, more articulate sound, while the vintage setting offers a slightly warmer, softer, and smoother tone.

Engaging the RF Filter.
To access the filter dip switch, unscrew the bottom bell counterclockwise from the base of the microphone, then gently slide out the brass body tube. The RF filter should be engaged when used in radio broadcasting, or when radio interference is an issue. The UT Twin87 ships with the RF filter is engaged by default. To engage the filter, lower switch positions 1 and 5, and raise switch positions 2, 3, and 4 (see Fig. 1). To bypass the RF filter, raise switch positions 1 and 5, while lowering positions 2, 3, and 4 (see Fig. 2). Switch position 6 should always be lowered.
