SLM4A is a desktop quad analog stereo audio meter. Comprising two 41 segment stereo bar graph meters, SLM4A displays both VU and Peak Program information simultaneously. A pair of "sticky" peak LEDs can be set to display peaks that exceed a preset limit. A seven segment phase correlation meter is included. Input connections to SLM4A are made on pluggable terminal block connectiors on the rear panel.
A rear panel dip switch array allows for configuration of various parameters such as meter ballistics and calibration levels of the SLM meters, please refer to the DIP SWITCH SETTINGS table in this manual. Connections to the SLM meters are made via pluggable 3pin
screw terminals when connecting analog or balanced AES signals or via BNC connectors when connecting unbalanced AES signals. If a viable AES signal is connected to the SLM the "LOCK" status LED will illuminate. If the signal is lost or corrupted the "ERROR" status LED will illuminate.
