Ordering Options – “S” – Mic-Level Outputs • The SC2000 BLL can be ordered with mic-level, (0.1 volts p-p), outputs instead of the standard line-level, (2.5 volts p-p), outputs on the Tape/Auxiliary Out and/or PC Audio Out connectors. • The mic-level option is used if these outputs are required to drive an external device having a mic-level signal input. Mechanical tape recorders, (such as Sony models ER8020 and ER-9060), often have only mic-level inputs. • Robotel uses the suffix “S” to designate a mic-level output configuration for the Tape/Aux output, and the suffix “SS” to designate a mic-level output configuration for both the Tape/Aux and PC outputs. Ordering Options – “M” – Stand-Alone Mixer • The SC2000 BLL is normally configured as part of a SmartClass system, and will be connected to a SmartClass workstation Interface module. • However, it is possible to order the BLL in a stand-alone configuration for non-SmartClass audio mixing applications. In such a configuration, the BLL unit requires an optional local power supply, (ALI-BLL-SA). One power supply can support two BLL units. (See diagram.) • Robotel uses the suffix “M” to designate a stand-alone mixer version of the BLL.
•
Ordering Options – “QUAD” – Additional Line Inputs • When equipped with the QUAD option, the SC2000 BLL mixes the mic signals, the intercom signal and up to 4 line-level inputs, (Tape/Aux, PC, A/V1 and A/V2). • With this option, the VCI control connector is removed.
•
Supplied Accessories • Every BLL model includes one 6 foot (1.8 meter) I-Link cable (RAL-TEL6PI) to connect from the BLL to the SmartClass Interface or power supply splitter. • Every BLL model includes a single 6 foot (1.8 meter) stereo audio cable (RAL-JACK3.5MM-DBL). Units equipped with one or more “S” options include two stereo audio cables. Units equipped with the “QUAD” option include three stereo audio cables.
