ACCESS PANEL FOR OPTIONAL EXPANSION MODULE

This panel is to be removed ONLY when installing one of a variety of Optional Expansion Modules that will be available soon for the Impulse® 12D. These Expansion Modules may include such options as a Wireless Input, a 10-Band EQ, a Digital Audio Input, etc.

These Optional Expansion Modules will either work in conjunction with the 2 inputs already present on the Impulse® 12D, or provide an in-line function for input 1, such as a 10-band EQ. Check with your Peavey® dealer for availability and price.

If you are not installing an Optional Expansion Module, then do not remove this cover. Instructions for installing an Optional Expansion Module will come with each Expansion Module and will be specific to that Module.

GROUND LIFT SWITCH (4)

Switches the XLR (7,8) PIN 1 (shield) from direct contact with ground in the event that hum occurs with the input cables connected. ALWAYS TURN THE GAIN (13 AND 14) DOWN ALL THE WAY BEFORE OPERATING THIS SWITCH TO AVOID LOUD POPS OR BUZZES! Turn the gain back up slowly and cautiously to determine if an improvement in the hum or buzz has been made!

INPUT 1 (A)

Input 1 is switchable between line-level gain and mic-level gain. The line-level input is medium impedance balanced. The jack (7) on the input 1 panel is a combo female XLR and 1/4” TRS connector. Input 1 also has a

3-conductor balanced Euro-style jack connector (9) wired in parallel with the above listed inputs. The signal to input 1 is mixed with the signal from input 2 and fed to the internal crossover and signal processing.
