These are typically single miked or multi-miked where each mic might be a different type and different distance from the source. So the TNT might be the ideal cost-effective solution for these situations – maximum choices & minimum cost and rack space and where you need to know you are using the one of the best. -

Normally this switch should be in the “+4 BAL” or Center position. Some PRO gear may prefer the “+4 unbalanced” position but this style of input is becoming increasingly rare, however because the TNT loses 6 dB of headroom in this mode, it can be used for crea- tive “drive”... -

14) GAIN TRIM POT: This pot is typically used to fi nely adjust the gain as needed for the recording device or converter. The two top LEDs are associated with this knob, and are intended to help set optimal levels, which are well (about 10dB) below when the TNT clips. -

Check the cables carefully because occasionally a cable gets modified to work with a certain unit and it seems to work but its wrong in other situations. If only one side of the TNT exhibits this problem, it may be a problem in the TNT. - Page 23 You might be accustomed to that preamp’s design flaws. With the TNT, changing the Impedance switch tends to be subtle. Worst case would be very low source impedance which corresponds with 4 dB gain change acrosss the five Impedance switch settings.

MAINS CONNECTIONS Your TNT has been factory set to the correct mains voltage for your country. The voltage setting is marked on the serial badge, located on the rear panel.
