QSC ISIS 215PCM - Manual

6 INTRODUCTION- Technical Overview Technical Overview: CH1 and CH2 Inputs are connected to the Top Box Processor and to the Mode Switch. In Combination Mode, the Mode Switch connects CH1 and CH2 Inputs to the Subwoofer Processor as well. In Discrete Mode, CH1 and CH2 Inputs are disconnected from the...

8 The 215PCM is highly durable and is carefully packaged and crated. We recommend you inspect theunit carefully after removing it from the packaging, as occasionally there may be damage due tosome unfortunate incident during shipment. Report any damage to the shipping carrier. Werecommend saving the...

10 Adjusting the Gain Settings of the Amplifiers PREPARATION FOR FIRST USE- Amplifier Gain Controls Ordinarily, the Gain controls of the amplifiers are left set at fullgain. This is not recommended for first-time users of freely-configurable DSP. Freely configurable DSP, while being the mostflexible...

11 The 215PCM requires 120 Volt, 30 Amp ACservice. Attempting full power operation onlower rated circuits may overheat wirirngand cause breakers to switch off.Use only heavy-duty 12 or 10 ga. extensioncords. The 215PCM requires a 120 Volt, 30 Amp connection to the AC mains.The power connectors used ...

12 To Configure a Processor (215PCM only) Each Processor has a 9-pin “D-sub” connector labeled RS-232. The RS-232 connection is used to configure the Processorby connecting to the PC’s COM port. Important points: – The 215PCM must be ON (powered up) in order to configure the Processors.– Each Proces...

13 CONNECTIONS- Mode Switch and Signal Routing The position of the Mode Switch determines how the input signals are routed. Select youroperating mode before making connections. If you are using the DataPorts for audio input,the Mode Switch has no effect. Refer to the diagram, below. COMBINATION MODE...

14 Audio Connections Audio inputs can be connected to the XLR inputs OR theDataPort connections (QSControl users). This sectionprovides information on using the XLR Inputs, For DataPortinformation see page 17. CONNECTIONS- Audio Connections: XLR Inputs CH1 and CH2 INPUT - In Combination Mode, use th...

15 XLR Connections The XLR inputs are electronically balanced. To maintain the benefits of balanced, pro-audio connections,make all connections to the 215PCM using balanced, high-quality cable and connectors. If balanced inputsare not available, use a unbalanced-to-balanced converter, such as a “DI”...

16 CONNECTIONS- Post Processor Outputs Post Processor Outputs Each processor has two post-processor outputs. Theyare labeled CH1 OUTPUT and CH2 OUTPUT. The audiopresent at these outputs is processed and the signalis the same as at the OUT1 and OUT2 blocks in theSignal Manager software. See Block Dia...

17 CONNECTIONS- DataPort (QSControl users only) When using the DataPort connections for audio inputs, do not use the XLR audio inputs. Any signalspresent on both connections will be summed, producing unexpected results. It is OK to use the XLRs foraudio input if the DataPort connection is used only ...

18 CONNECTIONS- Output to Top Boxes (Speakons™) Output to Top Boxes At the right side of the rear panel are the outputconnections to the top box speakers. Note the colorcoding scheme of the text labels for each Speakonconnector. The color coding corresponds with thecolors of the Mode Switch labels (...

19 USE- Cooling Air Inlet and Exhaust Vents The 215PCM contains two forced-air cooled QSCPowerlight 2-series amplifiers. They are mountedwithin the back portion of the enclosure. The amplifi-ers rely upon an unobstructed air flow in and out ofthe respective vents, shown below. Keep these airvents fr...

20 USE- AC Power Switch and LED Indicators LED Indicators Each Processor has two LED indicators,PWR and SIGNAL. The indicators arelocated on the rear panel of the215PCM. PWR- When the 215PCM is connected to a properly rated and working ACsupply circuit and is turned on, the bluePWR LED on each of th...

21 IMPORTANT USER CAUTION USE- LED Indicators (continued) and Important User Caution The 215PCM has been equipped with a very powerful internal amplifier. The amplifier power is severaltimes greater than the long-term power capacity of the drivers. This allows the full capacity of thespeakers to be ...

22 PROCESSOR USE- Software Installation and System Requirements 1. Insert the QSC Signal Manager CD into your drive (typically drive “D:”). If your computer has AUTORUN enabled, the installation will start automatically after several seconds. If it does not, then proceed to step 2, below. Otherwise,...

23 PROCESSOR USE: General Guidelines and Preset Description NOTE! The factory setting for all eight Preset memories is wire-through. Signals are passed from input to output without anyprocessing. Each Processor must be configured as desired bythe user. You may select configurations from the sample f...

24 Each Processor must be loaded with your desired signal processing configu-ration using the Signal Manager program before use. Test all new configura-tions for expected behavior at low power levels to avoid inadvertentlydamaging speaker systems. Each Processor has eight Preset memories numbered 1 ...

28 TROUBLESHOOTING The 215PCM “cuts-out” when I really crank it up (intermittent operation)- • Make sure the AC power source is rated for 120V, 30 Amps. Do not use 20 or 15 Amp AC supply circuits for the215PCM! Use only 12 or 10 gauge heavy-duty extension cords. • If the AC power source is “sagging”...

29 TROUBLESHOOTING Unable to “talk” to processor from Signal Manager software (OFFLINE status indicated)- • Check that the serial cable is a normal serialdata cable. Null-modem type cables will notwork. • Make sure that the serial cable is properlyconnected on both ends and that the retainingscrews ...
