Output processing is the same for both line outputs and onboard amplifiers in the case of Zone 4P and Zone 8P. There are fewer loudspeaker presets available for the on board amplifiers where they are not sufficiently powerful to drive larger loudspeakers.
Loudspeaker presets give the best performance for the loudspeakers in use. they are available on both Line and Amp outputs.
All Zone models come pre-loaded with presets for a range of Optimal Audio and Martin Audio loudspeakers. These are selected by clicking Settings>Line Outputs and selecting the desired output.
Selecting Line Output Preset will bring up a list of available presets. Choose the appropriate loudspeaker model for your system and click the back arrow at the top of the page to return to Line Output Settings. You will now see the chosen loudspeaker model named under Line Output Preset.
Simplifying the setup of a system, each output can be given a user name for quick reference. This is appended to the Output number such that it is clear from a wiring point of view on the back of the Zone unit and what should be connected to this output.
WARNING - For line outputs no limiter settings are included in the presets. Amplifiers can vary greatly in gain, making it impossible to have a standard limiter setting. When using loudspeakers and amplifiers from other manufacturers it is strongly recommended that the appropriate limiter settings are calculated and applied under Settings>Line Outputs> Line Output Processing> Limiter to protect your loudspeakers from damage.
The EQ settings for the best performance of the chosen loudspeaker can now be seen by clicking EQ under Line Output Processing. It is highly recommended that these are not tampered with and that the User EQ settings are used for any tonal balance changes you wish to make.
User EQ
Any additional equalisation required for room compensation or personal preference can be applied using User EQ on the same page.
Crossover
Line output crossovers feature two crossover filters - High Pass and Low Pass - and are intended primarily for use when a system includes subwoofers. When a speaker preset is selected, you will see the high pass filter in use - this is to protect the loudspeakers from damage by filtering out frequencies that the loudspeaker is not able to reproduce. The High pass should only be adjusted when a subwoofer is deployed with the selected loudspeaker.
To access crossover settings click Settings>Line Outputs> Line Output Processing>Crossover
This section can also be used to apply processing to any other combinations of amplifier and loudspeaker that are connected to the line outputs on any Zone product.
Within the crossover section of WebApp you have the option to select a crossover type. The two options are:
- Linkwitz-Riley 24dB/oct
- Butterworth 24dB/oct
Level Trim
This is useful for setting relative gains between speakers in 2-way systems.
Trim settings above 0dB should be used with caution. Where inputs have their gain settings correctly adjusted, it is possible to drive full scale output from line and amplifier outputs.
In this case any positive gain set here will simply drive the limiter harder.
Delay
A maximum output delay of 100. milliseconds is available for time alignment of loudspeakers in larger systems. Apply delay by typing in the desired time.
NOTE: To calculate a delay time, measure the distance between loudspeakers. Those near the back of the room will need delaying to the ones near the front.
