Impulse 115P: Subwoofer with Built-in Crossover

To fully utilize the built-in crossover‚ a line level‚ high-pass signal is available at the High-Pass output jacks (8). Use the Left output to send the high-pass output to a powered‚ full-range speaker or to a power amp and full-range speaker. The full-range speakers will reproduce frequencies from 120 Hz and up. This can be repeated for each Impulse 115P connected in this manner.

Impulse 115P: 3-Channel Stereo System

A full-range stereo signal may be run to the Left and Right inputs (5). The Mono switch (5d) must be in the Out (Off ) position to run in this mode. Connect a full-range‚ 8 ohm speaker system to the Left and Right output jacks (9). In this mode‚ the subwoofer will reproduce frequencies from approximately 45 Hz–120 Hz. The passively crossed-over‚ full-range Left and Right enclosures will cover from 120 Hz and up. This type of stereo connection will provide a mono subwoofer output with high-pass‚ crossed-over Left and Right stereo feeds. This setup will provide a very solid and punchy stereo playback system and is especially well-suited for portable DJ use.

2 Impulse 115Ps with 2 Passive Full-Range Enclosures

Connect a Left channel‚ full-range stereo signal to the Left inputs (5) of the first Impulse 115P. Ensure the Mono switch (5d) is in the In (On) position. Connect a full-range‚ 8 ohm speaker to the Left output jack (9). This will become the Left channel of the total system. Connect a Right channel‚ full-range stereo signal to the Left input (5) of the second Impulse 115P. Ensure the Mono switch (5d) is in the In or On position. Connect a full-range‚ 8 ohm speaker to the Left output jack (9). This will become the Right channel of the total system. Use of the Left channel In and Out on each Impulse 115P assures proper overall system operation. This setup can be repeated for each Impulse 115P connected for any number of channels.

Multiple Impulse 115Ps (or other powered products)

The Impulse 115P is designed with multiple‚ parallel inputs which allow daisy-chaining from one Impulse 115P to another. Connect the first cable from the mixer output to the first Impulse 115P. Then‚ connect a cable from the first Impulse 115P’s Thru jack to the second Impulse 115P’s input. This connection can be continued for several units‚ depending on the total length and capacitance of the cables. With a low- source impedance output from a typical mixer and by using quality‚ balanced cables‚ several Impulse 115Ps can be daisy-chained from one output using 30 or 40 foot cables without obvious problems or distortion. Do not connect cables to the jacks while the units are On and the Volume is turned up.

Applications

The Impulse 115P has a variety of applications such as sound reinforcement‚ public address or musical playback. DJ use is also supported when using the 3-channel stereo mode. Of course‚ using the Impulse 115P in the traditional role‚ strictly as a powered subwoofer‚ is also a great choice.

A typical signal source for the line level inputs (5) of the Impulse 115P would be a sound reinforcement mixing console (mixer) or the output from a CD player‚ MiniDisc player or tape deck.

No Output

First‚ make sure the unit has AC power and is turned on. Ensure the Power LED (4) is illuminated. If not‚ make certain the On/Off switch (3) is in the On position and check the IEC power cord connection (2) by ensuring it is fully engaged and seated. Make certain the AC line cord is plugged into a working AC outlet. Finally‚ check the fuse (1). (See the Rear Panel: Fuse section for safety instructions.)

Once assured your unit is getting AC power‚ check that the Impulse 115P is getting a signal. Disconnect the cable running to the Impulse 115P inputs and connect it to some other device capable of reproducing the signal (i.e. a power amp and speaker). If this produces a signal‚ make sure the Master System level control has been turned up to satisfactory level (1/3 to 1/2 up).
