With the mic input (8) switched ON (7), a microphone signal will be sent to the Quadra 15P’s preamp
electronics. Be sure to keep the mic away from the front of the speaker after switching the mic input
ON, and while setting the microphone level, or very loud feedback will occur! The person using the
microphone should stand to the side and slightly to the rear of the Quadra 15P, not out in front of the
speaker system. When not using the mic input, be sure to switch off the mic switch (7) for lowest
noise and hum pickup.
Set the microphone level using the Volume control (6), keeping in mind any possible volume
changes during the performance or presentation, and the possibility that the microphone may be
brought closer to the Quadra 15P later on. For best results, the microphone should be held close to
the person’s mouth, instead of a foot or more away. Do not “eat” the mic; that is, do not put your
lips directly onto the mic, as this can often result in a boomy sound. Best results are obtained when
the mic is approximately 2" to 3" away from the mouth.
When using the mic input (8) and the regular inputs (5) for simultaneous music and speech/singing,
the volume for the mic should be set first using the Level control (6) as described above. The level
fed to the regular inputs should be set to the desired level and matched to the microphone levels
using the source level control or a mixer.

This unit’s multiple parallel inputs allow daisy-chaining from one to another. Run the first cable from
the mixer to the first Quadra 15P, then connect a cable from one of the first Quadra 15P’s inputs to an
input on the second Quadra 15P. This can be continued for several units, depending on the length
and total capacitance of all the cables. With a low source impedance, such as a typical mixer output,
and typical balanced cables, two or three Quadra 15Ps can be daisy-chained from one output using
30' or 40' cables without obvious loss of high frequencies.
The Loop-Thru jacks (10) can also be used to connect one other Quadra 15P or one other Impulse
series powered unit, while conveniently controlling volume from just one of the units. Connect a
well-shielded 1/4" to 1/4" phone plug patch cord from the Loop Out jack of the unit connected to
the signal source and plug it into the other unit’s Loop In jack. The Volume control of the first unit
now controls the volume for both identically.
Do not connect cables to the jacks while the units are ON and the volume is turned up!

The Quadra 15P can be used in a variety of applications, such as sound reinforcement, public
address, side fill system or music playback. With the optional monitor stand kit, the Quadra 15P
makes an excellent stage monitor. Presentations or karaoke can be performed by using the mic
input and regular line-level inputs in conjunction.
A typical signal source for the line-level inputs (5) of the Quadra 15P is a sound reinforcement mixing
console (mixer) or the output from a CD player, Minidisc player or tape deck.
