Recommended Limiter Setting

Application Guide for

Yamaha Installation Series Speakers

Note that the figures are not a guarantee of protection for your speakers. Please refer to them on the understanding that they are provided as a guideline only.

Limiters allow you to provide speakers with maximum protection from unpredictable signal overload. We have provided the following table as a list of threshold figures, which should give you a starting point to work from. When configuring threshold settings, you will need to know the power ratings of the speakers and the gain of the amplifier to which they are connected.

The table in the following pages provides figures for amplifier gain levels of either 26 dB or 32 dB. For amplifiers with gain levels other than those listed here, deduct the positive difference of the gain from the figures listed for the 26 dB settings to calculate the correct setting. For example, for a gain level of 30 dB, subtract 4 dB from the figures provided for a 26 dB gain level to calculate each threshold.

For amplifiers with specifications displayed in terms of input sensitivity, calculate the gain from the power and input sensitivity figures, then use the calculation method above to obtain the correct threshold.

"DME library data for Installation Series Speakers" provides processor settings for Yamaha's "Installation Series Speakers" in the form of library data for DME24N/64N "Speaker Processor Components." Limiter settings (enabled by default) have been added to each library file.

The settings assume maximum output gain of DME (excluding DME24N's analog output) is +24dBu and 26dB voltage gain of Amplifier (based on Yamaha PC series amplifier used at -6dB attenuation) for start point.

If the set up differs from this, please check the level diagram and change the threshold parameters before using limiter.

E.g. If +18dBu output cards such as MY4-DA or MY8-DA96 are used, raise the threshold by 6dB. E.g. If amplifiers with 30dB voltage gain are used, turn the threshold 4dB down.

Speaker Processor “SP2060” also contains these library files for Installation Series speakers as default presets.

IF2112 specifications

The Yamaha IF2112 is a prominent addition to Yamaha's line of professional passive loudspeakers, designed to deliver exceptional sound quality and reliable performance in various sound reinforcement applications.
