Carvin TRX3210A TRx3210A manual - Page 15

TRx3210A Active Module and Settings The active TRx3210A triamp module is driven by X-Drive™ DSP processing with optimized presets for arrays and ground stacks. Crossover filters, Parametric EQ, Alignment Delay and Amp Limiters are factory tuned to maximize performance output. POWER SWITCH Push the upper portion of the power switch to turn the system on. If the blue POWER indicator is on but there is no sound check the Protect LED. POWER LED The POWER LED indicates the unit is turned on and functioning properly. SIGNAL LED The SIGNAL LED indicates there is a signal present at the INPUT XLR. LIMIT LED The LIMIT LED indicates maximum output of the system is being reached. A flashing LIMIT LED is acceptable. The DSP will reduce peaks to prevent amp clipping. If the LIMIT LED is continuously ON, reduce the level going in to the INPUT XLR. As with any system, reduce the volume if distortion is heard. PROTECT LED The PROTECT LED indicates one of the protection circuits has activated. To reset the amp, turn the power off for about 10 seconds, then turn it back ON. If the PROTECT LED stays lit for more than 5 seconds, check for a blocked fan intake. DIGITAL DISPLAY The bright green LED DIGITAL DISPLAY will display various information about the system and its settings. When you first turn on the unit, the display will indicate which preset is loaded. SETTING BUTTONS: UP/DOWN (SET) & LEFT/RIGHT Use the UP and DOWN (SET) buttons to load presets for different speaker configurations, based on the number of TRx3210A and the array angle set by the SureFly™TRx quick release pins. 1-4 boxes 0-2.5 deg (straight) 1-4 boxes 5-7.5 deg 1-4 boxes 10 deg 5-8 boxes 0-2.5 deg (straight) 9-12 boxes 0-2.5 deg (straight) 13-16 boxes 0-2.5 deg (straight) Use the LEFT/RIGHT buttons to access the Input Sensitivity setting and set with the UP/DOWN for 1.0 Vrms, 1.2Vrms, 1.4Vrms or 2.0 Vrms. The factory setting is 1.4Vrms. Increase the setting to lower the output. USB PORT The USB port is for updating system firmware such as additional presets. REMOTE LEVEL (MUTE) CONNECTOR This is a terminal block connector with 5 volt control of volume, typically used in permanent installations. Short the CTL and GND pins to MUTE. INPUT/THRU XLR CONNECTORS Connect the INPUT XLR to a signal source such as the output of a mixer. The THRU XLR can be connected to more TRx3210A's or other units. FAN INTAKE/EXHAUST VENTS The TRx3210A features a variable speed fan, which runs silent at low speeds. Make sure the fan intake and exhaust vents are free from blockage at all times. AC IN JACK (BLUE PowerCon™ A-type) The AC IN connector accepts the blue Neutrik™ PowerCon™ "A-type" connector (part# NAC3FCA). One NAC3FCA connector is supplied, attached to a short length of 3-conductor wire. You can use a longer wire if it is properly rated for the application. Attach a proper 3-prong connector for your voltage type to the other end of the wire, with careful attention to follow the correct pinouts and safety standards. No attempt should ever be made to use the unit without the ground connected. Plug into the proper voltage for your unit. Alternately, you can attach the grey Neutrik™ PowerCon™ "B-type" connector (part# NAC3FCB) for an A-B jumper cable between two TRx3210's. Pay careful attention to follow the correct pinouts and PowerCon™ wiring safety standards. With the con- nector attached, plug into the AC OUT jack of another TRx3210A, or into a PowerCon™ "B-type" outlet N with the proper voltage. L AC OUT JACK (GREY PowerCon™ B-type) The AC OUT connector accepts the grey Neutrik™ PowerCon™ "B-type" connector (part# NAC3FCB), and is used to power other units. Use the VA rating on other devices to determine how many can be connected to the AC OUT. The maximum limit on the AC OUT connector is 15A. Other limiting factors include the breaker rating for the AC line you are plugging into, wire type and (if used) generator capacity. FUSE The FUSE is located internally near the AC input. To check or replace, first remove the power cord and then remove the amp module from the speaker enclosure then remove the front panel to access the fuse. The fuse type is a 250V Slow Blow rated at 10A. 15
