The Basic Series provides a cost-effective solution in more limited applications that require full duplex, party line communication. All interconnections are made with standard, balanced microphone cable with XLR-3 connectors. Installation requires no expert knowledge, and clear layout of controls assures trouble-free operation with a very short learning curve. A current-driven interconnect loop ensures that operator listening levels do not change as stations are added to or removed from the network.

Headphone Amplifiers – High-quality, push-pull headphone amplifiers contribute to a system frequency response of 200 Hz to 15 kHz and a dynamic range of 80 dB. Output is 400 mW @ 200 Ohms. A proprietary frequency contouring circuit optimizes voice range reproduction to ensure exceptionally high intelligibility even in high ambient noise environments.
Headset Connections – Both the master station and beltpack accept either dynamic or electret microphones as standard. Mic gain is adjustable internally for optimum results with any microphone. A headset detection circuit ensures the mic pre-amp is active only when a headset is connected. A volume control enables the user to listen at any desired volume, and to balance levels on the two channels of the BS 216 Master Station.
Side Tone – Each user station includes a side tone trimmer for each channel to adjust level for the operator’s voice as heard through his or her own headset or loudspeaker.
Switch-mode Power Supplies – In case of short circuits, faulty wiring or excessive thermal conditions, the power supply will self-protect by reducing power output, eventually shutting down under prolonged extreme stress. Once the fault is corrected, the power supply automatically resets and restores normal operation.
TALK Function – TALK button with green LED indicator connects to all user stations and beltpacks on the indicated channel.
CALL Function – The combined audible and visual CALL alert adapts to both sound- and light-sensitive environments. An incoming our outgoing call signal is indicated by a large red LED. Pushing the CALL button for more than two seconds activates the internal BUZZER. Volume of the BUZZER can be trimmed or muted.
AUX INPUT – The 2-channel Master Station (BS 216) and Power Supply (BS 286) each offer a balanced auxiliary attenuated input normally used to carry the auditorium or on-air program audio. Inputs may be switched between line level and microphone level with 30 V phantom powering.
