LSP 500 PRO

Microphone Level Adjustment

This document describes the correct adjustment of the sensitivity of the wireless microphones and

their receivers in Slots 1 - 3 of the LSP 500 PRO in order to obtain an adequate microphone level for

different applications.

The LSP 500 PRO has three slots for installing microphone receivers of the Sennheiser evolution

wireless G4 series. In some applications, especially for speech (e.g. lectures or presentations), the

microphone sensitivity of the wireless transmitter (handheld or bodypack) needs to be adjusted to

achieve a sufficient level of the microphones.

The default microphone sensitivity setting of the evolution wireless G4 series is -12 dB. This is an

adequate level for singers and vocalists with a powerful voice. For speech, a more adequate level is

-6 dB or even 0 dB.

Sensitivity setup of the evolution wireless handheld transmitter

To manually set up the sensitivity of the handheld transmitter:

f Press the multi-function switch of the handheld transmitter to open the main menu.

f Move the multi-function switch to change to the “sensitivity” menu item.

f Press the multi-function switch to call up the menu item.

f Move the multi-function switch to adjust the input sensitivity.

f Press the multi-function switch to store the setting.

Output level of the ew G4 microphone receivers

The ew G4 receivers used with the wireless microphones have to be set to AF Out +18 dB in order to

get an accurate microphone level.

Also refer to the Application Note AN IS-1003 v1.0 for additional information on ew G4 receivers

used with the LSP 500 PRO.

Automatic sensitivity setup using the SYNC function (ew 300

G4 / ew 500 G4 only)

The microphone sensitivity of the wireless handheld and bodypack transmitters can be adjusted

automatically via the SYNC function of the EM 300-500 G4 microphone receiver. For that purpose,

the desired microphone sensitivity of the transmitter can be adjusted in the receiver and can then

be synchronised to any wireless transmitter of the Sennheiser evoultion wireless 300 G4 and 500

G4 series.

This is especially useful when you are using different wireless microphones with different micro-

phone receivers. You only need to adjust the sensitivity for the transmitters once in the receiver and

you can synchronise it to the every transmitter you are using in the respective application.

Adjusting the sensitivity for other applications

After using the wireless transmitters for speech applications with a microphone sensitivity of -6 dB

or 0 dB, you should make sure to adjust the microphone sensitivity for any following applications

which might require a different microphone sensitivity. Otherwise this might leed to unwanted

distortion.

If you are using the SYNC function with different receivers in other applications, you need to make

sure that the sensitivity parameters are also synchronised. If you do not activate the transfer of the

sensitivity parameters, the sensitivity of the transmitter might remain at -6 dB and might be too

high for other applications.
