Page 5: Introduction
Introduction Balanced Stereo Limiter The LIM012 balanced stereo limiter is a small size, easy to use, device that can be used for limiting the signal coming from an input device such as a mix-table, microphone, etc… that is then send to a (power)amplifier. Limiting this input signal will not only protect your PA system, but also enables you to comply to restrictions by law. When the input signal of this input device exceeds the desired level, the LIM012 will attenuate the output signal sent to the output device in such a way that it will again reach the desired level. This level can be set by turning the Limit switch and can be limited at 6 different levels: 0 dBV, -6 dBV, -12 dBV, -18 dBV, -24 dBV and -30 dBV. At the bottom the green LED’s indicate the limit level. When the output signal is exceeding the desired Level, attenuation will take place and the red LED will indicate the location of the Limitation (Left or Right). The LIM012 balanced Stereo Limiter has 2 channels that work separately whereby it can be used as a stereo, or 2 x mono limiter. The LIM012 needs to be connected to a 24 DC power source. The PSD242 Power supply is included. -

Chapter 3 Overview LIM012 Front panel The front panel of the LIM012 contains all the controls and indicators. 1) Power switch: By toggling this switch, the power for the LIM012 can be switched ON and OFF. The power LED will illuminate when the power is switched ON. 2) Limiting level adjustment switch: By changing the position of this rotatable selection switch, the limiting level can be adjusted. The switch has 6 different positions whereby the limiting level can be set between -30 dBV and 0 dBV. A screwdriver should be used to change the position. 3) Limiting level indication LED’s: By means of these green LED’s the selected limiting level will be indicated. The LED located next to the selected limiting level will illuminate when device is operating. 4) Limiting indication LED’s: These red LED’s will illuminate when the signal of the corresponding channel is beïng overdriven compared to the selected limit level. The limit circuit will intervene bringing the output signal to the selected level. -

Rear panel At the rear panel of the LIM012 are all the connections provided. 1) 24 Volts power connector: The included 24 volts power supply (PSD242) should be connected to this connector. Pay attention to the polarity when connecting the power supply. 2) XLR Input connectors: The signal coming from the input device such as an audio source, mixing table, pre- amplifier should be connected to the 3-pin Female XLR inputs. 3) XLR Output connectors: The output signal is available at these 3-pin Male XLR connectors. The output signal is the audio signal which is driven through the limiting circuit. The level of the output signal will always be lower or equal to the selected limiting level. -
