Set the EQ ON/OFF switch out (OFF). 3. Turn the POWER switch OFF. CONNECTIONS: 1. Connect the line-level signal from your mixer (or other signal source) to the INPUT jack on the TH15A rear panel (XLR connector). 2. Connect the supplied AC power cord to the IEC socket on the back of the loudspeaker.
Introduction The Mackie TH-15A Powered Loudspeaker delivers a chest-pounding 400W of peak system power via ultraefficient Class-D amplification. This means more power with less weight, perfect when portability matters. The 15” high-precision woofer provides punchy low-end and responds quickly to transients.

4. OL Indicator 8. LOW EQ The OL (overload) indicator lights when the amplifiers in the TH-15A are 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 amplifiers and you are getting the most from your TH-15As. This control gives you up to 15 dB of boost or cut below 80 Hz and it is also flat at the center position (U).
Protection Circuits There are several protection mechanisms designed into the TH-15A to safeguard the loudspeakers and amplifiers from inadvertent damage. CAUTION: The protection circuits are designed to protect the loudspeakers under reasonable and sensible conditions. Should you choose to ignore the warning signs (i.e., frequent OL LED indications, excessive distortion), you can still damage the speakers in the TH-15A by overdriving them past the point of amplifier clipping.
Appendix A: Service Information If you think your Mackie product has a problem, please check out the following troubleshooting tips and do your best to confirm the problem. Visit the Support section of our website (www.mackie.com) to get some ideas or contact our technical support heroes. You may find the answer to the problem without having to send your Mackie product away. If two fuses blow in a row, then something is very wrong. Try a different outlet in a totally different location.
Noise/Hum • Check the signal cable between the mixer and the loudspeaker. Make sure all connections are secure. These problems usually produce crackling noises or hum. • If you are using two or more TH-15A powered loudspeakers, try plugging them all into the same AC outlet panel or outlet strip. The purpose for this is to connect them all to the same earth ground point and reduce the possibility of creating a ground loop.
