Page 9: Where Do I Start
WHERE DO I START? 215PCM Powered Core Module Users- Install the Signal Manager software on the PC that will be used to configure the 215PCMs processors. See page 20. Put the 215PCM in a location that: • ..is close enough to the PC to connect the serial cable. •..has 120V, 30A service to power the 215PCM. -

This may not be the expected, desired result and could damage your speakers or hearing. For this reason, QSC recom- mends the initial “learning” sessions with the 215PCM be carried out with the amplifier Gain controls set at their minimum useful settings. -
Page 11: Ac Power
CONNECTIONS- AC Power AC Power Connection The 215PCM requires a 120 Volt, 30 Amp connection to the AC mains. The power connectors used are to be NEMA L5-30, or equivalent. The serial number plate is imprinted with the operating voltage informa- tion. -

Page 14: Xlr Audio Inputs
CONNECTIONS- Audio Connections: XLR Inputs Audio Connections Audio inputs can be connected to the XLR inputs OR the DataPort connections (QSControl users). This section provides information on using the XLR Inputs, For DataPort information see page 17. XLR Inputs The position of the Mode Switch determines how the input signals are routed. - Page 15 CONNECTIONS- XLR Connection Recommendations and Pinouts 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 inputs are not available, use a unbalanced-to-balanced converter, such as a “DI” box or proper audio transformer. Unbalanced connections are prone to noise and interference pickup as well as ground-loop induced hum.

CH1 OUTPUT receptacle. The Subwoofer Processor CH2 OUTPUT is not normally used. QSC recommends the use of balanced audio connections exclusively. We discourage the use of unbalanced connections as they are more prone to common-mode noise pickup and ground loop hum. -
Page 17: Dataports
Use only QSC Audio DataPort Cables for DataPort connections. They provide individually shielded audio pairs for the best possible audio performance. Computer VGA cables are similar, but can degrade your audio quality. QSC DataPort cables are available from QSC Technical Services Department. -

You will need to configure the preset memories with signal chains that meet the precise requirements of your sound system using QSC’s Signal Manager software. For help creating configurations, refer to the software’s on-line Help system for detailed information. -
Page 25: Configuring The Processors (Examples Of Signal Manager Software)
Processor Use: Configuring the Processors (Discrete 2.1) NOTE! The factory setting for all eight Preset memories is wire-through. Signals are passed from input to output without any processing. Each Processor must be config- ured as desired by the user. You may select configurations from the sample files (*.cfg) within Signal Manager or create your own. - Page 26 Processor Use: Configuring the Processors (Discrete 2.1 continued) Example 1- Discrete 2.1 (continued) The Subwoofer Processor is next. In Discrete Mode, the Subwoofer Processor’s input signal comes from the Input 3 XLR. Input 3 is routed to the Subwoofer Processor’s IN1 block (see example, below). The IN2 block is not placed when operating in Discrete Mode.
- Page 27 Processor Use: Configuring the Processors (3-way Mono Stack) Example 2- Active 3-way Mono Stack In a 3-way configuration, the Top Box amplifier’s two channels are used for low- and high-frequencies and the subwoofer handles bass. The Processors perform the required crossover and time delay functions. This Top Box configuration has time delays included in the DSP chain to align the impulse response of the audio.

Page 28: Troubleshooting
• Check each end of the power cord. The twist-lock connectors need to be fully inserted and twist-locked into place. • If using the DataPort inputs and QSC amplifier network control applications, the amplifier could be in STANDBY mode. Check with the system operator to place the amplifiers in POWER ON mode. If required, you can check this by temporarily disconnecting the DataPort cables to each Processor;... - Page 29 - Remember, all you need to do is switch the COM Port setting and then restart Signal Manager. • Consider upgrading to QSC’s amplifier network products. With QSControl, the Processor’s DSP is set up using the DataPort connections. No RS-232 connections are required and amplifier operating status can be monitored and logged.
- Page 30 The 215PCM supports two channels of amplification for Top Boxes. • QSC 8 ohm top boxes have dual-, feed-through Speakons that allow 1 or 2 additional top boxes to be daisy- chained.
