Introduction
The Y115P is a bi-amped powered full-range speaker designed to meet most any requirement. It projects
200 watts of clear, full sound. Features of this product include a Mic input, two parallel 1/4" input jacks,
Volume control, loudness switch, and a speaker/line input select switch. This three way cabinet is protected
against overcurrent and clipping via non-switchable (built-in) limiters.
Features
Line Level (balanced) / Speaker Input
Jacks
The two 1/4" jacks will accept either Balanced Line,
Line or Speaker inputs. In most cases, the input will
be from another speaker source, and therefore the
Input Select Switch should be IN.
Mic Input
The Balanced Mic input will accept most micro-
phones. The Input Select Switch must be OUT
for Line Level Inputs. When a Mic is being used in
conjunction with another source (music) through the
1/4" jacks, the output level from the other source will
automatically be attenuated.
Loudness Switch
The Loudness switch, when pushed IN, activates a
low-frequency boost when desired. This feature is auto-
matically reduced at high volumes to protect the speaker.
Ground Lift Switch
If a hum, or buzz is detected from the speaker, try
setting the switch to the GND LIFT position (OUT
position). The switch should otherwise be left in the
GND (IN position).
Volume Control
Set the Volume Control to the desired output level.
Start with a high Volume setting, with your mixer
turned down. Then, further adjust the mixer and
Y115P’s Volumes for best results.
A setting of 0 dB on the VOLUME control is the
correct starting point when setting up a sound sys-
tem when using the Line or Speaker inputs. The 0
dB mark refers to the setting that will give full power
when the line input is used and the input signal is at
a level of +4 dBV. This also is the setting to give a
sensitivity of 2.83 Vrms (1 watt 8-Ohms) for 100 dB
spl when set for speaker level input. Operation with
settings significantly above +12 may clip the circuitry
in the Y115P reducing the dynamics of the music.
Multiple Y115P’s
The parallel input jacks allow many Y115P’s to be
connected in a string. There is no practical limit to
the number of powered speakers that can be con-
nected together.
Power Switch
The unit can be turned on and off via the power
switch that is indicated by Power ON green LED at
the rear of the unit.
