2 FACILITIES 2.
3 INSTALLATION 3.1 Mains Supply When mounting or connecting the amp always disconnect it from mains. Only connect the TECTON amplifier to a appropriate AC circuit and outlet, according to the requirements indicated in the second line on the rating plate. TECTON-38.4 230 V ~ 50/60 Hz ,3 A 220 W 900 W / 4 Ohm TECTON-28.2 230 V ~ 50/60 Hz 9,5 A 002 W 400 W / 2 Ohm xxxxxxx TECTON-32.
3.3 Mounting Use four screws and washers when mounting the amplifier to the front rack rails. For mobile use, the amplifier should also be secured using the 19” mounting elements on the rear panel. 10 mm 7 mm 88,9 mm 76,2 mm 3 INSTALLATION 3.2. On/Off Switch The On/Off Switch is a rocker-type switch. It is located on the right side of the front panel. To turn the amplifier on, push in on the upper part of the switch. This initiates start-up by activating the inrush current limiter.
3 INSTALLATION 3.4 Cooling Under normal operation of the power amp, overheating should never be a problem. The air is taken in from the front and out through the back, it is of course essential that while the power amp is running air is able to circulate around it freely. The efficiency of the cooling will depend on the immediate environment (e.g. an enclosed rack, direct sunlight). If the amp is installed in a case, the open area at the back of the case must be at least 140 cm².
3 INSTALLATION 3.7 Mode Selector The switch on the rear panel changes the operating mode. Switch the power switch to the Off position to make changes on the Mode Selector. When the amplifier is switched on again, the selected mode will operate. 3.8 Wiring 3.8.1 E.U.I. and XLR Connection XLR: Pin 1 = Ground (or lifted via 15 Ω resistor) (See 3.5 Ground Lift) Pin 2 = Hot (inphase) Pin 3 = Cold (out of phase) Always use symmetrical (balanced) shielded cable to connect the amplifier.
3 INSTALLATION 3.8.2 Stereo Operation, 2 Channel Operation Two fully independent amplifier channels (normal operating mode). TECTON TECTON A (L) Z ≥ *Zmin A B (R) Z ≥ 2 *Zmin Z ≥ *Zmin 3.8.3 Parallel-Mono Operation Parallel operation of the two channels together. TECTON Zres ≥ 0.5 *Zmin A The output terminals of the two channels are configured in parallel using an internal relay. The (single) load is connected either to the output of channel A or to that of channel B (as if in stereo).
4 OPERATION 3.8.5 SPEAKON Connection Both SPEAKON connectors are connected to channel A and channel B outputs. The pin configuration of the SPEAKON connectors is as follows: WARNING ! SPEAKON connectors marked with the lightning flash indicate high vol tages that are potentially life threatening.
4 OPERATION 4.1 Controls 4.1.1 Volume Control A volume control with 41 notched settings controls the audio signal. These settings have been selected to correspond to human hearing characteristics (logarithmically) and therefore guarantee an optimal range of settings for practical applications. Each channel can be set individually except when operating in mono modes whereby only channel A is active.
4 OPERATION 4.1.5 HPF Filter (Channel A as example) Left position: HPF: Off 4.2 Indicators 4.2.1 Output Current LEDs The brightness is proportional to the output current in the channel. Output current of approx. 1 A lights up the LED at its lowest brightness level, while full brightness corresponds to the maximum rated current. Middle position: HPF: 30 Hz Right position: HPF: 50 Hz HPF OFF HPF 30 Hz HPF 50 Hz Low frequency response curves P.18 USER MANUAL TECTON POWER AMP SERIES 4.2.
4 OPERATION 4.2.3 Clip LEDs If the power level is overloaded, the Clip LED will light up. 4.3.3 DC Protection Each output of the power amp is constantly monitored for persistent DC voltage levels. If the 3 V thresholds are exceeded at any of the outputs, the corresponding channel will be muted. If DC was only applied for a short moment, the amplifier will release mute and work as normal. If DC is applied for longer periods or several short times the amplifier will switch to standby mode.
4 OPERATION 4.4 Mains Protections 4.4.1 Inrush Current Limitation Within 2 seconds of the amplifier being switched on, the inrush current limiter will increase mains current from nearly zero to nominal value. This value depends on program material, output level and speaker loads. 4.4.2 Mains Over Voltage Detection Mains over voltage detection is always operative. When the mains voltage exceeds approx. 267 V (230 V operation) or 134 V (120 V operation), the amplifier will be switched off.
5 OPTIONS 5.1 E.U.I.2 (Extended User Interface) CAUTION! Always switch off and unplug the TECTON from mains, before making alterations to the E.U.I. card. The E.U.I. card contains the Rear XLR Panel as standard. Other input cards are available (See 5.1.1 What Are The Possibilities Using The E.U.I.2?). To remove the E.U.I.2 unscrew the two Phillips head screws at the left and right end of the XLR-Panel and carefully slide out the E.U.I.2. To refit the E.U.I.2, carefully insert it.
6 TROUBLESHOOTING 6.1 Problem: No Sound Indication: Signal LEDs not lit Clip LEDs not lit Check AC plug. Confirm that AC outlet works by plugging in another device. Indication: Output Current LEDs are lit Signal LEDs not lit Make sure the signal source is operating and try another cable. Check position of volume pots. Indication: Output Current LEDs are lit Signal LEDs responding to signal level Check the speaker wiring for breaks. Try another speaker and cable.
