Sound Level Control Rack Mount System
Model: SLC1
- Triggering Circuit:
- This circuit will respond when the SLC1/SLC2 monitors a sound which is over the user's specified level.
- A switched output control relay and an audio attenuation circuit will be triggered.
- Switched Output Control:
- The SLC1/SLC2 provides a rear panel mounted terminal strip to which an installer can connect ancillary equipment suitable for the installation.

The Model SLC1 is a single rack space Sound Pressure Level meter with special triggering circuits. When monitored sound exceeds a specified level, a relay connected to a switched output is activated. The switched output can then activate connected ancillary equipment which can be used to notify the manager, light a light, ring a bell, or activate a compressor. It can even be used to activate a counter to determine how often sound exceeds the specified level. The choice of ancillary equipment is made by the installer to accommodate the particular situation.
A second relay allows the SLC1 to reduce sound levels by 6dB (20%) for 5 seconds. This feature is designed to encourage performers / DJs to reduce to the specified sound level.

- Triggering Circuit:
- This circuit will respond when the SLC1/SLC2 monitors a sound which is over the user's specified level.
- A switched output control relay and an audio attenuation circuit will be triggered.
- Switched Output Control:
- The SLC1/SLC2 provides a rear panel mounted terminal strip to which an installer can connect ancillary equipment suitable for the installation.
- This terminal strip becomes "active" when the switched output control relay is triggered.
- Connected equipment can range from a simple light bulb to a heavy duty solid state relay capable of handling multiple announcement devices.
- Audio Attenuation Circuit:
- The SLC1 will accommodate two audio channels.
- The input and output connectors for these channels are hard wired through the unit and will not interfere with the sound quality.
- If connected, the audio attenuation circuit will reduce the all over sound level by 6db (20%) for a 5 second interval.
- If the sound level is not reduced the circuit will be repeatedly activated to reduce the sound level for 5 second intervals.
- The switched output control circuit and the audio attenuation circuit can be utilized simultaneously or independently.
- The Controls
- Set: (SLC1/SLC2)
- The set control is provided to specify the maximum allowable sound level.
- SPL Weight: (SLC1/SLC2)
- Measurements can be made in SPL FLAT, A, or C.
- The Response Control: (SLC1 Only)
- A potentiometer is provided to determine how quickly the SLC1 will respond to a signal that exceeds the specified level.
- At minimum the SLC1 is most sensitive and will respond quickly to a small amount of overage.
- As the control is advanced, it will take longer to respond to the same amount of overage but will respond more quickly to a larger overage.
- At maximum the SLC1 will take a while to respond to a small overage but will respond relatively quickly to a large overage.
- Recovery Control: (SLC1 Only)
- This control has been pre-set by the factory to cover most situations. A cap has been placed over the control.
- For special applications the customer can remove the cap and re-set this control.
- The recovery control determines how quickly the SLC1 responds to occasional bursts that exceed the specified level.
- At minimum the SLC1 will ignore short duration bursts that exceed the specified sound level.
- As the control is advanced, the SLC1 will retain the effect of shorts bursts longer resulting in a more sensitive response.
- At maximum the unit will be factoring in any overages regardless of duration.
- Reset Delay Control: (SLC1 Only)
- The reset control sets the time interval after the relay is triggered before it will allow the relay to trigger again.
- The minimum interval is approximately 10 seconds and the maximum interval approximately 120 seconds.
