3. Slowly turn up the LEVEL control on the TH-18s to the “U” (unity gain) mark at the center position. 4. Adjust the master volume on your mixer to a comfortably loud listening level. -
Page 5: Introduction
Paired with a Mackie TH-15A or the popular SRM450v2, you have a complete (and completely affordable) “plug and play” system that is ideal for small clubs, DJs and rehearsal spaces. The TH-18s has both full-range and high- pass stereo outputs for connection to full-range top boxes. Just dial in the appropriate level and use the polarity switch to make sure the sub is in phase with the loudspeakers. -

Their respective full-range outputs feed the inputs of another pair of subwoofers. The high-pass outputs from the second set of subwoofers then feed the inputs of a pair of powered loudspeakers.

9 10 THERMAL SIGNAL POWER LEVEL POL ARITY NORMAL INVERT 3. INPUTS Balanced XLR female connectors are provided for the left and right inputs. Connect the full-range line-level signal from the mixer or other signal source to these input jacks. If you are connecting a single subwoofer output, or LFE (low-frequency effects) output to the subwoofer, you may use either the A or B input connector. -

INPUTS 9. OL LED The OL (overload) indicator lights when the amplifier in the TH-18s is near the clipping point. It is okay if the OL indicator blinks occasionally, because this means that the transient peaks are just reaching the maximum output of the amplifier and you are getting the most from your TH-18s. -
Page 11: Ins And Outs Of Polarity
Listed below are some recommended configurations for pairing a Mackie TH-18s subwoofer (using the High- Pass output) with a Mackie full-range loudspeaker. These settings are a good start, but be sure to experiment to find the best sound for your venue. -
Page 12: Protection Circuits
(i.e., frequent OL LED indications, excessive distortion), you can still damage the speakers in the TH-18s by overdriving them past the point of amplifier clipping. Such damage is beyond the scope of the warranty. -
Page 13: Appendix A: Service Information
For example, if a left subwoofer is presumed dead, switch the left and right cords at the subwoofers. If the problem switches sides, it’s not the TH-18s. It could be a bad cable, or no signal from the mixer. Bad Sound •... - Page 14 Make sure all connections are secure. These problems usually produce crackling noises or hum. • If you are using two or more TH-18s powered subwoofers, try plugging them all into the same AC outlet panel or outlet strip.

Page 15: Appendix B: Connections
For example, if your mixer has an output impedance of 120 ohms, then you can daisy chain up to nine TH-18s’s. This is a load of 1222 ohms (TH-18s input impedance=11 kohms; 9 of these in parallel=1222 ohms). Since microphones typically have a higher output impedance, you should limit daisy-chaining from a mic source to two TH-18s’s... -

73 lb / 33.1 kg Mounting Method: The TH-18s subwoofer is designed to sit on the floor or stage. It is NOT designed to be pole-mounted or suspended. The cabinet has no rigging points and is not suitable for rigging. -
