iP 24

Multi-function DSP



Multi-function DSP loudspeaker management system (single 19” rack unit) featuring the iMode Technology to control external amps and passive sound reinforcement systems
2-IN/4-OUT Analogue and Digital (AES3) configurable matrix
2 GPI – General Purpose Input, 2 GPO – General Purpose Output configuration settings on a DB9 connector (with +5V and GND) that allows third party integration of alarm/fire systems, power control, mute, and fault notification to an external monitoring system
Extremely advanced WFIR (Warped Frequency FIR) filtering technology, which is based on the same principle as the human ear, distributing the frequency resolution over a semi-logarithmic scale
Raised Cosine modelling for parametric, shelving and band pass filters for each input stage
Ethernet Switch with 2 Ethernet Ports


In a major advancement of Outline’s proprietary iMode Processing Platform, the iP24 is a multi-purpose 2-input/4-output DSP loudspeaker controller housed in a single 19” rack space. For the first time, it provides all the features associated with the iMode platform, now able to control external amplifiers and passive sound reinforcement systems.

The iP24 uniquely features WFIR (Warped Frequency Finite Impulse Response) filtering technology, based on the same principle as human hearing. WFIR filtering – not found in other loudspeaker control systems due to the limited amount of DSP they provide – distributes the frequency resolution over a semi-logarithmic scale and produces a more natural auditory response.

Outline iP24 ensures really superior precision. The tools provided by iMode technology to control sound systems’ response include modern Raised Cosine filters. Compared to traditionally implemented parametric functions, they provide better transfer curve shaping, controlling intervention frequency bandwidth more precisely while maintaining minimum-phase response.

All onboard audio I/O can operate in either analogue or digital, and connection via standard Ethernet protocol allows total system control via PC web browser, as well as iPhone / iPad and Mac OS X. The 2 Inputs/4 Outputs can be configured in a number of ways depending on the application requirements. Inputs and outputs can run as either analogue or digital (AES3).
