Frequently asked questions
When installing a limiter based on a measuring microphone, a few problems can rise, which not
everyone will realise in advance. To give a better insight in the operation of the limiter, the most
frequently asked questions and their answers are mentioned below:
If the crowd makes too much noise (singing along with the music), the SPL3/3TS reduces
the output level. How do I prevent this problem?
Especially in relatively small rooms, where the maximum allowed sound level is relatively low, the
crowd is often capable of drowning the music. Of course this will be detected by the measuring
microphone, and the limiter can only do one thing: reducing the music level, which is totally
comprehensable, but rather undesired. This problem can be prevented by mounting the
microphone at a location where the balance between crowd and music tends to tip the
scale in favour of music (closer to the speakers). Another possibility is not using the measuring
microphone. Realise that after relocating or switching off the measuring microphone, the limiter
needs to be recalibrated.
I only use the SPL3/3TS for live music. What to do with the threshold trimmer?
The threshold trimmer has no function in live-mode. The setting of the threshold is only
important in the case the microphone is not used. In that case the limiter is monitoring the input
signal in order to calculate the nessecary attenuation. When using the microphone, only the
measured microphone-sound-level is important.
Even with the SOUND LEVEL trimmer turned fully clockwise, the maximum sound level is
too low. What to do now?
It is likely that the maximum sound level is far higher than what will be allowed by the authorities.
The SPL3/3TS is designed to handle sound levels from as low as 80 dBA to nearly 120 dBA. If
for one reason or another, more sound level is desired, increase the distance between
microphone and speakers. This way the limiter will detect a lower sound level, so the limiter will
apply less reduction.
With a live band, some instruments and the vocals are going via the main PA-system,
through the SPL3/3TS. The other instruments are protected with the switched sanction
output of the limiter. When the maximum level is exceeded, all sources via the main PA-
system will be attenuated, while all "self support" instruments remain at the original level,
so the whole balance of the mix is gone.
This is right. The SPL3 and SPL3TS are not suitable to be used in music mode and live mode at
the same time. When the maximum level is exceeded, there is only one sensible thing to do for
the limiter: reducing the output level, which will disturb the balance of the mix if some instruments
are not controlled by the VCA's of the limiter. Use the limiter only in live mode in such cases.
