Frequently Asked Questions - TCX118B-R Turbosound
How do I connect the TCX118B-R to a mixer?
Use a balanced XLR or TRS cable from the mixer's output to one of the combo inputs on the subwoofer. Ensure the amplifier is turned off during connection.
What power supply does the TCX118B-R require?
It operates on 100-240 V AC, 50-60 Hz. Use the supplied IEC power cord and connect to a grounded outlet. Do not use an extension cord with insufficient rating.
Can I daisy-chain multiple TCX118B-R subwoofers?
Yes, use the XLR link output to connect to the next subwoofer's input. Ensure the total impedance does not exceed the amplifier's rating if using passive mode, but with built-in amps, simply connect audio signal.
What does the protection LED indicate?
The protection LED illuminates when the subwoofer is overheating, overcurrent, or limiter is active. Reduce volume or allow cooling. If persistent, check ventilation and connections.
How should I place the subwoofer for best performance?
Place on a solid, level surface away from walls to avoid excessive reinforcement. For optimal bass, position in corners or near walls. Use the pole mount for satellite speakers.
Is the TCX118B-R magnetically shielded?
No, it is not shielded. Keep it away from CRT monitors or magnetic storage media to avoid interference.
What is the warranty period?
Turbosound offers a standard 2-year warranty from the date of purchase. Register your product online for extended warranty options.
Can I use the TCX118B-R outdoors?
Yes, but protect it from direct rain and moisture. The polyurea coating provides some weather resistance, but prolonged exposure to water may damage the electronics.
How do I clean the grille?
Remove the grille by unscrewing the retaining bolts. Use a soft brush or dry cloth to remove dust. Do not use water or cleaning solvents.
What is the maximum SPL and frequency response?
Maximum SPL is 130 dB continuous, 136 dB peak. Frequency response is 40 Hz to 100 Hz (±3 dB). These specs make it suitable for sub-bass reinforcement.
