CONNECTIONS- Post Processor Outputs

Post Processor Outputs

Each processor has two post-processor outputs. They are labeled CH1 OUTPUT and CH2 OUTPUT. The audio present at these outputs is processed and the signal is the same as at the OUT1 and OUT2 blocks in the Signal Manager software. See Block Diagram, page 7, for details.

These are electronically balanced outputs with an impedance of 600 ohms with the shield terminal connected to the chassis. The outputs are suitable for daisy chaining the post processor signal on to other devices in the system. We recommend that no more than five balanced, pro-audio devices be daisy chained from any output.

The output connectors on the Processors are three pin terminal block connectors. They are sometimes called “Phoenix- or Euro-type” detachable terminal blocks.

The appendix provides part number information on these connectors.

Top Box Processor- Both CH1 and CH2 OUTPUTs are active for most applications. The signal output from each connector is same as the signal applied to the inputs of the top box amplifier.

Subwoofer Processor- Use CH1 OUTPUT only. CH1 OUTPUTs signal is the same signal applied to the input if the subwoofer amplifier. CH2 OUTPUT is not normally used.

The post processor outputs are recessed, located on the processor faceplates. Each processor has post processor outputs suitable for daisy chaining the processed audio on to other devices in your system using detachable terminal block connectors.

NOTES: The output levels of each processor are dependant on your settings in the Signal Manager

software when you configure the processor. If post processor outputs do not behave as expected,

connect your host PC to the processor and verify your configu- ration.

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.

Subwoofer post-processor output is available for daisy chaining from the CH1 OUTPUT receptacle. The Subwoofer Processor CH2 OUTPUT is not normally used.

ISIS 215PCM specifications

The QSC Audio ISIS 215PCM is a powerful loudspeaker designed to meet the demands of professional audio applications. Known for its exceptional sound quality and robust construction, the ISIS 215PCM is engineered to deliver a superior listening experience in various settings, including live events, concerts, and installations.

One of the main features of the ISIS 215PCM is its dual 15-inch low-frequency drivers, which provide deep, resonant bass and a wide dynamic range. This design allows for high SPL (Sound Pressure Level), making it suitable for large venues. The enclosure is strategically designed to enhance performance by minimizing distortion, thus ensuring clear audio reproduction even at high volumes.

The ISIS 215PCM is equipped with a high-frequency compression driver coupled with a wide dispersion horn. This combination yields excellent high-frequency response and seamless integration with the low-frequency drivers. The dispersion pattern has been meticulously engineered, enabling consistent sound coverage throughout the audience area, which is essential in live sound applications.

In terms of technology, the ISIS 215PCM features advanced acoustic design principles that optimize both performance and durability. The enclosure is constructed from high-grade plywood and reinforced to withstand the rigors of touring and installation, while the dual ports facilitate enhanced airflow and reduced turbulence, resulting in accurate sound reproduction.

Additionally, the loudspeaker employs a sophisticated passive crossover network that effectively separates frequencies, allowing each driver to operate within its optimal range. This technology minimizes phase issues and ensures that the transitions between the low and high frequencies are smooth and natural.

Portability is another significant characteristic of the ISIS 215PCM. It includes robust handles for easy transport and installation, making it a great choice for sound engineers and technicians who need to set up and break down equipment regularly. The professional-grade connections further enhance convenience and reliability in diverse applications.

Ultimately, the QSC Audio ISIS 215PCM is a remarkable loudspeaker that combines innovative technologies, premium materials, and thoughtful design. It is ideal for audio professionals seeking a reliable solution that delivers exceptional sound quality and performance. With its versatility and robust features, the ISIS 215PCM stands out as a formidable choice for both live sound and permanent installations.
