#Hollyland Spares - 4-Pin XLR Power Supply (EU), For Syscom 1000T & Mars T1000

The Hollyland 4-Pin XLR Power Supply (EU Version) is a heavy-duty, direct replacement AC/DC adapter engineered specifically to power the central base stations of the Syscom 1000T and Mars T1000 wireless intercom systems.

Unlike consumer electronics that rely on fragile barrel jacks, professional broadcast base stations use locking 4-pin XLR DC inputs to prevent accidental cable disconnects on active production sets. This specific SKU includes a standard European Type-C/E/F wall plug.

Core Technical Specs & Pin Architecture

• Input Range (AC): Universal 100V to 240V (~50/60Hz), making it compatible across EU grids and versatile for international travel with simple plug adapters.

• Output Range (DC): Steps down voltage safely into the wide 7V to 36V DC power requirements native to Hollyland base stations (typically outputting a stable 12V or 24V supply).

• Standard 4-Pin XLR Output Layout: Uses industry-standard broadcast wiring conventions to protect your equipment:

  • Pin 1: Ground (GND / Negative)

  • Pin 2: No Connection (Null)

  • Pin 3: No Connection (Null)

  • Pin 4: Power (Positive / +V)

Key Advantages for Production

• Locking XLR Mechanism: Features a rugged quick-release latch button that locks securely into the base station’s chassis. It cannot be pulled loose by a crew member tripping over a cable.

• Heavy-Shielded In-Line Transformer: Built with thick rubber strain relief and an internal ferrite core filter. This blocks electromagnetic interference (EMI) and radio frequency interference (RFI), keeping the intercom channel free from background hums or buzzes.

Hot-Swapping Tip: Both the Mars T1000 and Syscom 1000T base stations feature integrated dual NP-F battery plates alongside the 4-pin XLR input. If you need to move your master station desk position mid-event, keep two charged NP-F batteries mounted onto the unit. You can unplug the 4-pin XLR mains power line without shutting down the station; the system instantly shifts to battery power without dropping connection to any active crew beltpacks.
