SPL2(TS) and SPL3(TS) user manual Installation

Introduction

The SPL2, SPL2TS, SPL3 and SPL3TS are sound pressure limiters (SPL), especially designed for

use in public houses, discotheques, etc. The SPL-limiters are no peak-limiters, they only limit the

average sound pressure. Trimmers for on-site calibration are positioned behind removable cover

(plates) which can be put under seal.

The four different Dateq SPL-limiters form one family. The SPL2 and SPL2TS function without a

microphone, the SPL3 and SPL3TS use a special measuring microphone. The SPL2TS and

SPL3TS are supplied with a timer, able of setting the maximum sound level for certain periods of the

day (see table 1). Basically, all four types are identical. This manual covers all different types.

Directions for one specific type are indicated with a logo in the left margin.

Measuring microphone (advantages and disadvantages)

In some cases, authorities dictate the use of a measuring microphone. Also when using the limiter

with live-music, a measuring microphone will be essential. Using a measuring microphone can have

advantages and disadvantages.

• Calibrating the limiter usually takes place during the day, in an empty room. When this room fills

with a crowd during the night, acoustical damping will occur, so the maximum sound level will be

lower than the level set earlier. When making use of a microphone, the limiter will compensate for

this difference.

• Using a measuring microphone can be a disadvantage in smaller rooms, with relatively low

maximum sound levels (less than 100 dBA). In these situations, the crowd can easily drown the

music, when singing along. This will be detected by the microphone, and the limiter can only react
