INTRODUCTIONGeneral Overview
Introduction
Thank you and congratulations on your purchase of the ISIS 215PCM Powered-System Control Module or 215SB Subwoofer. This product represents the state-of-the-art in all-weather, lightweight SR (sound reinforcement) loudspeaker systems. The “215” marks the introduction of QSC’s ISIS loudspeaker systems. ISIS is short for Integrated, Self-Powered—Self Processed, Industrial Systems. To get the most from your investment, we encourage you to review this manual carefully.
The 215PCM is a self-contained active subwoofer system with dual 15-inch drivers. It provides power amplification not only for itself, but also two channels for driving fullrange or biamp “top box” speakers as well. It is the most advanced core module for portable live sound reinforcement systems and is ideal for corporate and industrial events. The 215SB is a passive subwoofer system with no backpack electronics, equipped with a single Speakon™ connector.
215SB Subwoofer Highlights
Composilite™
QSC enclosures incorporate Composilite, a patented cored composite technology that yields superior acoustic properties, lighter weight, and greater weather resistance compared to conventional enclosure materials. Multiple skins of carbon fiber are layered over a honeycomb core to form a rigid, seamless enclosure. The extreme stiffness of Composilite construction prevents flexing of the cabinet enclosure, significantly reducing energy loss due to cabinet vibration. The result is reduced enclosure loss, increased low frequency output, and substantially less sound radiating from the back and sides of the enclosure for greater sonic accuracy. Furthermore, the enclosure’s light weight translates to safer rigging and reduced handling costs.
The frequency response of the 215PCM is 35 to 150 Hz (-3 dB). Two 15-inch, diametrically opposed (facing each other) drivers fire in opposite directions with equal excursion. The net effect being the driver forces counterbalance, minimizing vibration in the cabinet. This is essential in lightweight, ultra-stiff cabinet designs to keep the walls from vibrating excessively and to keep the cabinet from “walking away” during use.
215PCM Powered Control Module Highlights
The “PCM” version adds a 55 pound amplification and signal processing backpack to the 215SB subwoofer cabinet. This backpack houses two independent power amplifiers, one for the subwoofer and one for the “top boxes”. Driving the subwoofer is the equivalent of a bridged-mode PL230 amplifier providing up to 3000 watts to the two 15-inch drivers. Top boxes are powered by the equivalent of a PL236 amplifier (725 W/ch. @8 ohms, 1100 W/ch. @ 4 ohms, 1850 W/ch. @ 2 ohms). Signal processing is provided by two DSP-3 Digital Signal Processors with 24-bit, 48 kHz. convertors. Both processors have eight userconfigurable and -selectable presets. An RS-232 connection to a PC running the provided QSC Signal Manager Software enables system tuning and configuration.

INTRODUCTIONTechnical 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 Subwoofer Processor, and Input 3 is used to feed the Subwoofer Processor.
Independent DSP is provided for each amplifier. The DSP engines are 24-bit resolution, 48 kHz. sampling rate. They boast less than 0.01% THD+N, 20 Hz. -20 kHz. ±0.7dB frequency response and a dynamic range exceeding 93 dB. All that is required is configuring the Processors with the desired signal chain before use.
Each Processor must be configured using QSC’s Signal Manager software, included with the 215PCM. Install the software on a PC meeting the specified system requirements, then connect to the Processors (one at a time) with an RS-232 connection and run Signal Manager. Each Processor has 8 Preset memories enabling the most used configurations to be saved as convenient, easy to recall Presets. The last applied configuration will be the power-on default, ensuring the system powers-up in the state it was last left. Refer to the software’s on-line Help system for detailed information. All software related operation information is located in Signal Manager’s Help system.
The Top Box Processor’s OUT1 and OUT2 DSP ports are connected to the 3600 watt Top Box amplifier’s CH1 and CH2 Inputs, respectively. The Top Box amplifier is configured to operate in stereo mode without any filtering. All filtering and is done in the Processor.
The Subwoofer Processor’s OUT1 DSP port is connected to the Subwoofer amplifier’s CH1 Input. The Subwoofer amplifier is operated in Bridge Mode. The amplifier has no filtering. All desired processing must be done in the Processor. The Bridge Mono outputs are wired internally to the subwoofers.
Post Processor output connections are provided on each Processor. These 3-pin terminal block connectors make daisy-chaining the processed signal to other equipment a snap.
The amplifiers are modified QSC Powerlight2 models. They feature PowerWave™ high frequency switching power supplies for maximum performance and minimum weight. Gain controls are preset to full, but each amplifier’s Gain controls are accessible through small access holes in the respective cooling air intake grill; this allows a relatively tamper-proof maximum gain setting. The amplifiers provide features such as soft-start inrush current limiting, tempera- ture-tracking bias control, variable speed cooling fans, and full output protection.
A variety of Top Box speakers are connected to the Speakon™ connectors on the rear panel. The upper Speakon is wired for optional biamp use (4-wire), and the lower Speakon is wired normally (2-wire). This connection scheme allows for biamp users to plug into one connector for all four biamp wires, while still keeping the standard two Speakons for two channel applications.

PREPARATION FOR FIRST USEAmplifier Gain Controls
Adjusting the Gain Settings of the Amplifiers
Ordinarily, the Gain controls of the amplifiers are left set at full gain. This is not recommended for first-time users of freelyconfigurable DSP. Freely configurable DSP, while being the most flexible and desirable, will do precisely what the user configures it to do. This may not be the expected, desired result and could damage your speakers or hearing. For this reason, QSC recommends the initial “learning” sessions with the 215PCM be carried out with the amplifier Gain controls set at their minimum useful settings.
Each of the two cooling air exhaust vents (one on each end of the cabinet) has two small, rectangular openings for adjusting the Gain controls. The exhaust vent closest the wheels has the access holes for the Subwoofer amplifier. The exhaust vent closest the handles has the access holes for the Top Box Amplifier.
Below, the illustration shows the location of the Subwoofer amplifier’s gain adjustment access holes. The Top Box amplifier’s access holes are on the vent located on the other end of the cabinet (left, as viewed). The access holes are not labeled. This is to discourage gain tampering after the 215PCM is set up. Use a 6- inch #1 flat blade screwdriver or similar tool. Fiberglass-shaft TV adjustment tools work well, are nonconductive, and won’t scratch equipment easily. Use a flashlight to aid in locating the gain control.
Gain control adjustment access holes (Subwoofer amplifier shown). The lower hole accesses CH1’s gain control. CH2’s gain control has no effect because the Subwoofer amplifier is configured in bridge mono mode at the factory. Access is available for CH2’s gain control for users that modify the 215PCM. Note that modifications may void warranty.

CONNECTIONSAC 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 information.
At peak output power, the 215PCM can supply up to 6,600 watts of music power. At these levels, the AC line current can easily reach levels in excess of 20 Amps. Proper AC connections are required at such high power levels.
Connect the 30 Amp twist-lock connectors by orienting the locking L- shaped prong with the corresponding connector entry, then fully insert the three prongs. Twist the plug about 1/8 of a turn clockwise to lock
the connector and plug.
Power switch.
The 215PCM requires 120 Volt, 30 Amp AC service. Attempting full power operation on lower rated circuits may overheat wirirng and cause breakers to switch off.
Use only heavy-duty 12 or 10 ga. extension cords.
AC Power Switch
Above and to the right of the AC entry connector is the Power switch. The switch is labeled POWER ON, above it.
To turn the power on: Press in on the upper portion of the rocker switch. Both DSP-3’s blue Power indicators should illuminate.
To turn the power off: Press in on the bottom portion of the rocker switch. It may take a few moments for the Power LED’s to extinguish. This is normal.
215PCM AC connection. The keyed connector fits only one way. Align the “L” shaped tang with the mating receptacle and fully insert, then twist 1/8 turn clockwise to lock in place. Reverse procedure to remove plug.
11
CONNECTIONS- RS-232 Processor Configuration Connection
RS-232 Connection (215PCM only)
Each Processor has a 9-pin “D-sub” connector labeled RS-232. The RS-232 connection is used to configure the Processor by connecting to the PC’s COM port.
Important points:
–The 215PCM must be ON (powered up) in order to configure the Processors.
–Each Processor is configured individually.
–The serial cable connection is not required after configuring a Processor.
–Configurations are kept in the Processor’s nonvolatile memory and on the PC.
RS-232: Used to setup (or configure) the Processor. Connect to your PC’s COM port using a normal 9-pin serial data cable (25 ft. maximum length). The Signal Manager software used to create your DSP chain “talks” to the Processor through the computer’s COM port connection. Once the Processor has been configured, RS232 connection is no longer required. Any change to the Processor’s setup requires the RS-232 connection to the PC’s COM port.
To Configure a Processor (215PCM only)
1- Install the included Signal Manager software on a PC/laptop meeting the minimum system requirements. See page 22 for complete installation instructions.
2- Connect a normal 9-pin serial data cable between your PC’s COM port and the RS-232 connector of the Processor you want to set up (or configure).
3- Start the Signal Manager software and establish communication between the PC and the Processor. If the status indicator (bottom right of the Signal Manager window) shows ONLINE, the software and Processor are connected. If it does not, verify cable connections and refer to the top of page 29, Troubleshooting.
4- Use the Help system to learn how to use Signal Manager.
12
CONNECTIONSMode Switch and Signal Routing
MODE SWITCH (215PCM only)
The position of the Mode Switch determines how the input signals are routed. Select your operating 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– Use CH1 and CH2 Inputs OR Input 3 (mono).
Typical “Left-Right” mixes will provide a stereo feed for CH1 and CH2 Inputs. CH1 and CH2 Inputs will be routed to BOTH Processor’s IN1 and IN2 blocks (see diagram, below).
If only one input (mono) or one side of the mix is available, then use Input 3. Input 3 will route the input to the IN1 block.
DISCRETE MODE– Use all three inputs. CH1 Input is routed to the Top Box Processor IN1 block, CH2 Input to IN2. Input 3 is connected to the Subwoofer Processor IN1 block. Note, the Subwoofer Processor’s IN2 is not connected when operating in DISCRETE MODE.
SIGNAL ROUTING BY MODE SWITCH
The mode switch effects how
the input signals are connected
to the Processors.
