Superlux IS103A Starter System 3 users (max of 10 users)

A complete single-channel wired intercom starter system built around the Superlux CS101A user station — the right choice where one position needs to hear comms through a loudspeaker rather than wearing a headset.

Unlike a beltpack, the CS101A has a built-in loudspeaker, making it ideal for any user who cannot or does not want to wear a headset whilst working — a sound mixer already wearing monitor headphones, a lighting user at a desk, or a showcaller who needs to hear the intercom line without a headset. Press-to-talk operation for reply. The loudspeaker can be switched off when the position needs to go quiet, and a line out allows connection to an external active speaker for larger rooms.

This kit includes:

• 1× Superlux CS101A compact user station with loudspeaker + rack kit
• 2× Superlux BP101 wired beltpacks (steel, black finish)
• 3× Superlux HMD685A single-sided dynamic headsets (2 for beltpacks, 1 for CS101A)
• 1× Superlux PS101A power supply (supports up to 10 users)

XLR 3-pin cable (standard microphone cable) required — not included.

Call alert on every position
Both the CS101A and BP101 feature light and sound alert — so calls are never missed even in noisy environments. The sound alarm on the BP101 is switchable.

Expandable to 10 users
The PS101A supports the CS101A plus up to 9 BP101 beltpacks. Additional BP101 beltpacks and HMD685A headsets are available separately — see related products below to expand your system up to 10 users.

Compatible with existing wired kit
Altair, ASL, Stonewood and Tecpro beltpacks are compatible with this system — useful if you already have beltpacks from another installation.

Typical applications: Theatre and live events, broadcast and sporting events, sound and lighting desks, showcalling positions, houses of worship, schools, colleges and educational institutions.
