System Requirements
TCX series two-way loudspeakers operate as passive systems and
require only one amplifier channel for correct operation; the internal
passive crossover network built into each enclosure splits the
frequency range appropriately between the LF driver and the HF driver.
TCX loudspeakers are equipped with two Speakon NL4 connectors
wired in parallel with a 4-way barrier strip connector, providing input
and loop-through connections to additional TCX series loudspeakers.
To avoid wasting amplifier power you should use heavy-duty speaker
cable with a minimum wire size of 12 gauge (1.5mm²), and preferably
10 gauge (2.5mm²) for longer runs. For extreme cable lengths be
aware of cable impedance and resistive losses. Always observe the correct polarity as shown.
Amplifier Considerations
TCX series loudspeaker enclosures should be driven by high quality power amplifiers designed for true
professional use. Power amplifiers should be capable of delivering long term broadband power equal
to the loudspeaker’s program power rating at its stated nominal impedance. The use of under-powered
amplifiers must be avoided as heavily clipped signals can cause permanent loudspeaker damage.

System Controllers
TCX systems can be used with TURBOSOUND LMS-D24 or LMS-D26 controllers to provide improved
performance as well as vital operating and system security features. If you do not have a controller,
please contact your TURBOSOUND dealer for further details. TURBOSOUND LMS-D2X controllers provide
preset slots into which you can load TCX loudspeaker model parameters, available as a free download.
To use your TCX loudspeaker with a TURBOSOUND controller:
1. Download and install the TCX loudspeaker presets from the TURBOSOUND website turbosound.com.
2. Power up the controller(s) and associated power amplifiers.
3. Press RECALL to select the appropriate program from the preset menu using the ‘A’ ROTARY ENCODER.
4. Press RECALL again to accept the preset. The controller will un-mute and is then ready for use.
