Application Guide for

Yamaha Installation Series Speakers

Recommended Limiter Setting

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.

“DME library data for Installation Series Speakers” can be freely downloaded from the Yamaha

website. http://www.yamahaproaudio.com/

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

default presets.
