Hollyland Spares - D-TAP to DC 2.1 Power Supply Cable (for Wireless Intercom Series)

The Hollyland D-Tap to DC 2.1 Power Supply Cable (Model: HL-DT01) is an official factory-spare power interface accessory designed specifically to drive the base stations of professional Wireless Intercom Systems from high-capacity cinema batteries.

Unlike standard short cables meant for lightweight camera-top accessories, this dedicated intercom power cable is engineered with a longer reach and structural reinforcements. It allows production crews, technical directors, and sound engineers to power their entire communication hub directly from a V-Mount or Gold Mount block battery when filming on location without access to main AC wall outlets.

Core Electrical and Structural Features

• Continuous Intercom Hub Operation: Engineered to supply stable power to high-draw multi-user intercom base stations, allowing for full days of uninterrupted crew communication on location.

• Premium Heavy-Duty D-Tap Male Pin: Connection Terminal A features an industry-standard male D-Tap (P-Tap) connector. The internal gold-plated contact pins are designed to prevent arcing and maintain a constant electrical flow, even during sudden voltage spikes.

• Locking 2.1mm DC Barrel Connector: Connection Terminal B features a $2.1\text{mm}$ male DC plug with an integrated threaded locking collar. This screws securely onto the base station’s power input, completely preventing accidental power loss if the cable is tugged or tripped over on set.

• Extended Cable Length Profile: Measuring 39.3 inches (100 centimeters) in length, this cable provides the extra reach needed to neatly route power from a battery bracket on the bottom of a sound cart up to an intercom base station mounted at the top of the rack.

System Interoperability

This heavy-duty DC power bridge is designed specifically to interface with:

• Hollyland Intercom Infrastructure: Solidcom M1 Base Station, Mars T1000 Base Station, and Syscom series intercom mainframes.

• Cinema Power Sources: Professional V-Mount or Gold Mount batteries, sound cart power distribution blocks (such as PSC or Remote Audio), and cinema battery plates equipped with standard female D-Tap outputs.

On-Set Intercom Power Management Advice

Wireless intercom base stations draw a steady, continuous amount of power because they manage multi-channel radio networks and cross-routing systems simultaneously. When running your intercom station off a V-Mount or Gold Mount battery via this D-Tap cable, avoid stacking high-draw camera accessories (like high-bright production monitors or wireless video transmitters) onto the exact same battery if possible. Splitting your power sources helps prevent low-voltage drops, ensuring your crew's critical communication channel remains crystal clear and completely uninterrupted mid-take.
