Tube PAC. You’ve undoubtably noticed that the Tube PAC is as cool sounding as it looks. After getting familiar with the Tube PAC, you’ll realize what a great investment you’ve just made. The Tube PAC may be used everywhere! Anywhere you need level adjust- ments (gain or attenuati ...

award-winning circuit designs - one of the finest tube microphone preamplifiers available and one of the finest optical tube com- pressors available. Developed in partnership with studio and live sound engineers, the Tube PAC possesses a “sound” that is not available from any other p ...

for audio engineering and recording. Enclosed in a table-top (and 1/2 rack-able) chassis are two independent circuits featuring a tube-based analog preamplifier and a VCA-less, tube-based compressor with optical gain reduction control. Used as a mic/line preamp or as a DI (direct) box, t ...

SETTING UP Unpacking Your Tube PAC was packed with care at the factory. The shipping carton was designed to protect it during initial shipment. Please retain this carton for use in transporting the Tube PAC, or in the unlikely event that you need to return your Tube PAC for servicing. AC Power Hookup The Tube PAC has ...

to moisture. Do not remove metal panels from chassis parts. Removing the chassis from its cabinet parts exposes dangerous high voltages. There are no user-serviceable parts inside. Refer all servicing to qualified personnel. Note: If your power cord becomes damaged and mu ...

+20dB gain switch. You may control two ranges of gain with this control, +26 to +60dB and +6 to +40dB. When setting the Gain control, refer to the 4 segment Tube Drive Array for a visual refer- ence to the Tube PAC’s internal signal levels (applied gain). Hint: the “sweet” spot for the Tub ...

Four LEDs display how the tube gain is affecting the input signal. These LEDs are calibrated with the tube circuitry to give you an accurate representation of the tube’s output signal (Note: these LEDs measure the signal level before the output level control). Use this meter as a visual for setting the Gain level. The firs ...

trol fully clockwise. After setting the Gain control, slowly turn the Threshold control counter-clockwise (lowering threshold) until you see the yellow (0dB) Threshold LED light. Now adjust the control (either lower or higher) until you have the amount of compression you desire. Use the G ...
