REAR PANEL TOP
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
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
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.
TOP – OPERATING CONTROLS, INPUTS & OUTPUTS
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.
