PRECISION 8i OPERATION MANUAL

∙ Use high-quality, low capacitance cable. Braided shielding and “star quad” type mic cables will perform better in electrically noisy environments. Manufacturers such as Canare®, Mogami® (and others) make high performance cable of this type.

∙ Some “house brand”cables are made by quality manufacturers, but others can be inferior. Be careful. Use cables with high-quality connectors (Neutrik®, Switchcraft®, etc.).

∙ Our studio testing has shown that some of the more esoteric guitar/instrument “super-cables”do, indeed, sound better. Noticeable improvement, but at a stiff price. Try before you buy!

∙ Avoid excessive cable length. ∙ Replace damaged connectors.

3Overload warning indicator. OL illuminates (and holds) at +26 dBu which is 5 dB below actual overload. Depress RESET 10 to clear OL.

4Peak-Hold indicators. These are provided to help optimize level setting when the PRECISION 8i is remotely located from the device to which it is connected. The PK indicator activates (and holds) at the level selected on the PEAK REFERENCE selector 9 . The -3indicator activates at peak level minus 3 dB. The -6indicator
