For optimal performance the PowerDual™ iQ 18B has been designed to operate with PowerDual™ iQ 10 mid/high cabinet, where overall system control is achieved by utilising the TDX2 system controller. The TDX2 has been factory preset to provide the recommended cross-over points, delays and overall system balance. Please refer to the TDX2 manual for operation.

If you intend using an alternative loudspeaker management system (e.g. BSS™, Klark Teknik™, XTA™ etc) please contact your distributor or visit our website, www.tannoy.com for the correct parameter settings or refer to the recommended crossover points in the technical specifications section of this manual.

7. Equalisation

The iQ 18B loudspeaker is designed to need no equalisation or correction to overcome system limitations. As a result, it will only need equalisation to compensate for difficult acoustic environments.

Over equalisation can reduce system headroom, and introduce phase distortion resulting in greater problems than cures. If equalisation is required then it should be applied gently and smoothly. Violent equalisation will be detrimental to the overall sound quality.

Furthermore, its build quality is robust, designed to withstand the rigors of continuous use in busy environments while providing lasting performance.

The IQ 18B also offers versatility in installation. It features a Power over Ethernet (PoE) capability, allowing for easier cable management and reducing installation costs. Furthermore, the speaker can be controlled remotely, giving users the flexibility to adjust settings from a distance, which is particularly beneficial for larger venues.

To enhance user convenience, the IQ 18B comes equipped with a front-mounted volume control and an LED indicator. This allows for quick adjustments and status monitoring without needing to access the rear of the unit, making it user-friendly for both operators and maintenance personnel.

In summary, the TOA Electronics IQ 18B stands out as a powerful and efficient loudspeaker solution.
