Introduction

The Y118PW powered subwoofer incorporates a 200 watt amplifier. It can be used to enhance the bottom end (bass) of a full-range speaker system and increase the overall output of the system. The inputs to the subwoofer can accept a single source either from a speaker/amplifier output or a line level output from a pre-amp or mixer.

The Y118PW also has a built-in limiter and thermal protection that make this product smooth and robust at high power levels. The internal limiter and the internal protection are factory set to maximize performance.

Features

Power Switch & Power On LED

When the unit is turned on, the green LED (located on the top left hand of the control panel, near the Yorkville logo) will illuminate.

Input Level Switch

Speaker

Normally, the input to the subwoofer is from a full- range speaker cabinet, or amplifier output.

Line

In this case, the input to the subwoofer is from a line level source such as a mixer.

Volume

A setting of 0 dB on the SUBWOOFER LEVEL control is the correct starting point when setting up a sound system. From there the sound can be adjusted for best sound. 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. With a typical full range compan- ion speaker this will give flat response. In either line or speaker operation it will usually be desirable to set the control at +3 to +6 to give some bass boost at low power levels. At levels approaching full power the built-in limiter will automatically reduce the gain to prevent over powering the subwoofer. Operation with settings significantly above +12 may clip the cir- cuitry in the subwoofer reducing the dynamics of the music. Setting the subwoofer gain above +12 is only appropriate at low operating levels.

Ground Lift Switch

If a hum, or buzz is detected from the subwoofer, try setting the switch to the GND LIFT position (OUT position). The switch should otherwise be left in the GND (IN position).

Input Jacks

The two inputs are 1/4" parallel jacks and can be connected as shown in figures 2 and 3, on the fol- lowing page. Please note that there is no effect to the performance of the full-range speaker if it is used to supply a music signal to the Y118PW.

Multiple Y118PW’s

As well as accommodating the full-range speakers, the parallel input jacks allow many Y118PW’s to be connected in a string. There is no practical limit to the number of Y118PW’s that may be connected together.

User Note

For normal operation connect the Y118PW just like any ordinary speaker along with the full-range speakers. The input level switch should be set to speaker. If the audio source does not have a U ground (a ground pin on the AC cord), the ground lift switch must be set to gnd. The Y118PW may be wired before or after the full-range speakers. The Y118PW does not alter the signal to the full-range speakers. The Y118PW will not draw any power from the amplifier driving the full-range speakers. Please note that an external crossover is not neces- sary.
