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).

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.

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).

When this switch is in the ON position, the mid-range is reduced by approximately 4 dB.

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 high-Z jacks, so do not run the cable very far.

If it is necessary to remove the rear panel, or re-install it, then the bolts for the rear panel must be loosened or
tightened by removing the front speaker grille, and then the woofer, and reaching in from the front to restrain the
nuts from spinning. The unit must be disconnected from the AC power source before any work is done on it.
Refer all servicing to qualified service personnel.
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 line-level strength signal.
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 hard-wired together to allow use of any of the connector types as an input,
and to allow a further send or "daisy-chaining" of the input signal to some other audio device (such as another
Impulse 1015P). Attempting to run two different signals directly into the Impulse 1015P could damage the
outputs of the source units. Use a mixer to combine two or more signals into a single signal sent to the Impulse
1015P input.
