The TRxSUB3 system is setup to have each DCM3800Lx power amp bridged into one TRx2218b dual 18-inch cabinet. This provides full power avaliable for Max SPL of the TRx2218b. Two PRO50TL 50ft cable are provided for connecting the subwoofers to the power amps. One C1XLR short XLR balanced cable is provided for setting up the system as mono and chaining the two power amp inputs together.
The TRx2218B is our powerful Dual 18-inch subwoofer system. The high power, 18-inch woofers features a 4-inch voice coil with low temperature high peak power capacity. The box is designed with four deep large corner located ports producing a very strong structure, and coherent sub frequency output vertically and horizontally. The added strength rigidity of the corner ports puts all the force of the speaker out the front and into the room, and not wasted on the walls vibrating. This provides the idea low frequency coupling in multi box clusters, both in the horizontal and vertical positions.
The TRX2218B features foot locating holes on top for stacking another TRx2218B and for stacking up to 4 TRx3210 line array elements without hardware. Top centered pole mount for suspending a TRx2115 or TRx12N. The enclosure is constructed of CNC machined 13-Ply Premium Russian Baltic Birch with heavy gauge steel powder coated front grills. The crossover includes two 4 pin twist lock high current connectors mounted on FR4 double sided circuit boards for solid construction and durability.
DCM3800Lx X-Drive Power Amps:
The 3800 watt DCM3800Lx amplifier can be configured for stereo, parallel, bi-amped, or bridged outputs. The System Quick Setup feature makes output routing and crossover configuration easy. Loadable Speaker Presets tuned for specific CARVIN speaker cabinets provide optimized settings to get the most out of each element in your system. The DCM3800Lx includes 30-band graphic EQs on each input, 4 parametric EQs on each output with high and low crossover filters; Bessel, Butterworth or Linkwitz-Riley (6 to 48dB/oct.), Limiters with Threshold, Phase, and Delays up to 120mS for distance or for individual driver alignments. Onboard memory has enough storage for 16 complete system configurations with settings for multiple loudspeakers and line arrays, or store unlimited configurations on your laptop. Premium 24-bit A/D and D/A converters offer low noise with full 20-20kHz bandwidth with extremely low latency processing.
The DCM3800Lx front panel features a high-contrast 2x16 character display for clear and easy navigation through settings. LEDs for Signal, 50%, 80%, Clip and Protect monitor the status of the amp. Detented level controls prevent unexpected level changes. Balanced XLR and TRS input connectors are used to reject hum & noise. A Ground Lift switch removes the chassis ground from the inputs. Outputs feature heavy duty binding posts and Twist-Lock connectors allowing bi-amp routing on a single 4-pin cable with no adapters.
DCM3800Lx Computer Interface
Every DCM-Lx amp is thoroughly tested, which includes a full burn-in under load. Construction starts with a heavy duty 2U aluminum chassis and steel rackmount face panel. All circuit cards are double-sided military-grade FR4 fire retardant with plated thru holes so parts are soldered from the bottom side through to the top. SMT (surface mount technology) offers high precision and "shock-proof" protection. The CB and CE safety seal assure that each DCM meets strict standards anywhere in the world.
The DCM3800Lx's high headroom reveals the dynamic power available from its switch-mode power supply. Operating at 100,000 Hz, the highly efficient switch-mode supply reduces AC power required from the wall, overall weight, and is AC generator friendly. The soft-start prevents the DCM-Lx from tripping AC breakers. Extreme currents are delivered to even the most demanding 2 ohm and bridged 4 ohm subwoofer systems easily handling the most difficult reactive loads. Class D outputs deliver maximum power amp efficiency.
