[. . . ] TECTON USER MANUAL INFORMATION FOR USE FOR TECTON 38. 4, TECTON 32. 4, TECTON 24. 4, TECTON 28. 2, TECTON 22. 2 and TECTON 14. 2 TUM_GB_2004-200-R2_09-200 © Copyright 200 by CAMCO Produktions- und Vertriebs-GmbH für Beschallungs- und Beleuchtungsanlagen Fischpicke 5, D-57482 Wenden, Germany Telephone +49 (0) 2762 408-0 P. USER MANUAL TECTON POWER AMP SERIES IMPORTANT SAFETY INSTRUCTIONS IMPORTANT SAFETY INSTRUCTIONS ) Read the information for use (user manual). 2) Please keep this user manual in a safe place during the lifetime of the amplifier. The user manual forms an integral part of the amplifier. Reselling of the amplifier is only possible if the user manual is available. [. . . ] In stereo mode (2-channel) none of them will be lit. In Parallel-Mono the (PM) LED will be lit and in Mono-Bridge, the (MB) LED will be lit. 3. 5 Ground Lift The input signal ground (pin for all 4 XLRs) is connected to the ground of the mains supply. In order to avoid ground loops, this connection can be separated via a resistor. The ground potential of the power amp and the ground of the loudspeaker always remain connected to the ground of the mains supply regardless of the setting of this switch. Amplifier in Parallel-Mono mode Amplifier in Mono-Bridge mode Lift Position Ground Position to Pin of the XLRs Removing or taping the mains connector ground is illegal and dangerous. DO NOT REMOVE MAINS CONNECTOR GROUND IT IS ILLEGAL AND DANGEROUS P. 3 USER MANUAL TECTON POWER AMP SERIES 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. and XLR Connection XLR: Pin = Ground (or lifted via 5 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.

TECTON A TECTON Z *Zmin A B 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 second channel processes the same input signal, but with reversed phase. The (single) load is connected between the two positive channel outputs using a suitable connected SPEAKON connector. While the total output of the amplifier remains the same, both the available output voltage and the minimum impedance that can be connected are doubled, as compared with stereo operation. A signal feeding channel B will have no effect on the output. Turn the volume of channel B down to zero. In Mono-Bridge mode RMS output voltages are as high as 230 V. Wiring to the speaker loads must conform to NEC Class 3 safety standards or its equivalent that meets all national and local electric codes. All customer specific cables may only be manufactured by qualified suppliers/personnel. All cabling or rewiring work must be carried out by qualified personnel. * Zmin = 2 for TECTON 28. 2, 22. 2 and 14. 2 * Zmin = 4 for TECTON 38. 4, 32. 4 and 24. 4 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). While the total output of the amplifier remains the same and the output voltage level is also the same as in stereo operation, the minimum impedance that can be connected is reduced by half due to the fact that current capability is doubled. The channel B-Input is inactive ­ turn the volume of channel B down to zero. This mode is useful when, for example, 3 identical loudspeakers are to be operated with the same power. P. 5 USER MANUAL TECTON POWER AMP SERIES 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: SPEAKON right: Pin + (View at the back) Pin Pin 2+ Pin 2SPEAKON left: (View at the back) WARNING !SPEAKON connectors marked with the lightning flash indicate high voltages that are potentially life threatening.
