CONNECTIONS- Mode 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.

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.
