Frequently Asked Questions - TORUS T820 Martin Audio

What is the coverage angle of the TORUS T820?

The TORUS T820 has a horizontal coverage of 120° and a vertical coverage of 30° that can be adjusted by changing the splay angle between cabinets.

How do I connect multiple T820 cabinets?

Use Neutrik speakON NL4 cables. The cabinets have two connectors for looping through. Ensure total impedance load does not fall below the amplifier's minimum rating.

What amplifier is recommended for the TORUS T820?

A high-quality amplifier capable of 400W into 8 ohms per cabinet is recommended. For multiple cabinets, use amplifiers rated for the total load.

Can the TORUS T820 be used outdoors?

Yes, but it is not weatherproof. Protect from rain and humidity. Use a cover when not in use.

How do I clean the TORUS T820?

Use a soft, dry cloth to remove dust. For grime, use a damp cloth with mild soap. Do not use solvents or abrasive cleaners.

What is the maximum SPL of the TORUS T820?

The maximum peak SPL is 133 dB at 1 meter.

How do I rig the TORUS T820 for a flown array?

Use the integrated rigging system with the provided captive pins. Always follow the rigging manual and ensure structures are rated for the total weight.

What type of enclosure is the TORUS T820?

The enclosure is made of birch plywood with a durable polyurethane coating and a steel grille.

Is the TORUS T820 compatible with subwoofers?

Yes, it can be used with Martin Audio subwoofers such as the SX218 or SX118 for full-range reinforcement.

Where can I find a replacement driver for the TORUS T820?

Contact Martin Audio customer support or an authorized dealer. Use only genuine Martin Audio parts to maintain performance.

HRIG100

The HRIG100 is a rigging accessory used to suspend TORUS in a horizontal configuration. The HRIG100 can be mounted to a cabinet or between two cabinets, given the best options to suspend multiple cabinets.

HRIG100 can be mounted on the top or bottom of the cabinet in portrait mode, this allows the HF horn to be positioned at the top or the bottom of the array.
