Standards applied: EMC Emission EN55103-1, E3 EMC Immunity EN55103-2, E3, with S/N below 1% at normal operation level. Electrical Safety EN60065, Class I This equipment is tested and approved according to the U. S. [. . . ] Output operation and connection Screw-terminal connectors with + and ­ poles are provided at each channel output for connection of the speakers. Two electronically balanced Phoenix-type inputs are available. Follow the +, ­ and Ground labels when connecting the input signal. If an unbalanced connection is desired this can be achieved by summing the minus ("COLD") and Ground terminals and using the + terminal as the "HOT" signal. For the best possible performance, the summing of ground and minus wires should be done at the source unit end of the cable (e. g. Four connectors are supplied for attaching cables to the inputs. The type of connector used is: Phoenix Contacts, Part number MSTB 2, 5/3-STZ-5, 08 When linking the same source signal to several input channels, be aware that there is a limit to the number of channels an output source can "drive". a DSP crossover unit) can drive up to 4 amplifier channels before line-drivers would be required to buffer the signal. Make sure that the speaker cables are connected correctly and tightly, and that accurate polarity is maintained to all speakers in the system. As the amplifier outputs produce high voltage, do not connect or disconnect speaker cables when the mains power is on. Also, attach the safety cover on the speaker terminals for safe operation and to comply with electrical product approvals. 16 Q Series Operation Manual All material © 2007. The VPL allows you to set the correct maximum output peak power for optimum performance with the connected speakers. The correct setting depends on the system type (lo-or hi-impedance) and the specific load connected to the channel. Since each channel can be configured to deliver either very high voltage peak power OR high current draw at low impedances, it is important to set the VPL correctly. To configure an individual output channel for a constant voltage system, you simply adjust the DIP switches to the desired voltage. However, when using an output for a low impedance system (2, 4, 8 or 16 ohms), then sometimes you need to adjust the VPL to a lower setting to avoid either delivering excessively high continuous power to the Q Series Operation Manual 17 All material © 2007.

For example, with a very "hot" conti-nuous output signal, the temperature could rise to a critical level and activate Temp warning or even Temp Mute. Lowering the VPL setting normally will solve this situation. If the Current Peak Limiter is active or indicates low impedance, lowering the VPL setting can rectify this situation as well. 7. 4. 6 Constant Voltage 70 V and 100 V systems setup and operation When using Q Series amplifiers to drive constant voltage (hi-impedance) speaker systems at 70 Vrms or 100 Vrms, you can in most cases simply connect the speakers to the amplifier output terminals, select the correct VPL setting, and place the amplifier in service. 7. 4. 7 Output Current Peak Limiter (CPL) The Current Peak Limiter (CPL) ensures that the amplifier will not be damaged by trying to deliver more current to the outputs than that physically possible for the transistors.

The Voltage Peak output values translate to rms Voltage for a sine wave as: peak/1. 41 = Vrms. 141V peak is 100V rms and 100V peak is 70Vrms. This means that the outputs can be set for high impedance loads without the use of an external transformer. [. . . ]
