- 1 DCM3800Lx X-Drive 3800W Power Amp
- 2 PRO50TL 50' Speaker Cables

TRx2121 Subwoofers:

The TRx2121 is a compact high Q sub-subwoofer design to add extended ultra-low frequencies to any system. Effective for both permanent and portable applications, coupled with the TRx3210 Line array elements provides very powerful extended full range system. The TRx1121 features added foot holes for stacking up to four and dual pole mounts for suspending up to two TR3210s. And third centered pole mount for a TRX12 or TRX115.

The TRx2121 is our finest single 21-inch Subsubwoofer system. The high power, larger format 21-inch woofer features a 4-inch voice coil with high peak power capacity. The box is designed with four large corner located ports producing a coherent sub frequency output vertically and horizontally. This makes the idea low frequency coupling in multi box clusters both in the horizontal and vertical directions.

The TRX2121 features foot locating holes on top for stacking another TRx2121 and for stacking up to 4 TRx3210 line array elements without hardware. Three top pole mounts feature 16" spaced dual pole system for suspending two TRx3210 speakers, and a single centered pole mount for suspending a TRx115 or TRx12.

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.
