the mic level is set using this knob, and the ancillary signal (music into the In/Out jacks) level is then set using the source or feed (mixer).
(7) MIC ON SWITCH
When this switch is in the ON position, it connects the mic input jack (8) to the preamp circuitry. If the microphone is not in use, this switch should be in the OFF position to minimize noise or hum pickup from the mic input.
(8) MIC INPUT
Female XLR input jack for microphone use with the Impulse 1015P system. This connector provides +15 Volts phantom power and gain suitable to most of today’s “hot” microphones. When using this input in conjunction with the regular inputs (5), the volume for the mic should be set first using the Volume (6) control, and the level fed to the regular inputs should be set to the desired level using the source level control (mixer).
(9) CONTOUR SWITCH
When this switch is in the ON position, the
(10) LOOP-THRU JACKS
After the signal goes through the balanced inputs and the Volume control, these send the signal to another Impulse 1015P via its Loop In jack.
These are unbalanced
OPERATING INSTRUCTIONS
If it is necessary to remove the rear panel, or
The heat sink on the back plate can become hot to the touch. Do not block or cover the heat sink from ventilation.
Be sure to keep the microphone away from the front of the speaker after switching the mic input ON and while setting the microphone level, as very loud feedback will occur! Damage to the system is likely if this occurs!
DO NOT connect the inputs of the Impulse 1015P to the output of a power amplifier. The inputs are designed to be driven from a
DO NOT remove the protective metal grille.
DO NOT use the Input/Output jacks as mixers by trying to run more than one signal source at a time into them. The Input/Output jacks (5) are all
