Frequently Asked Questions - Trimode Radial Engineering
What is the Radial Engineering Trimode?
The Trimode is an active direct box with three selectable operating modes: Instrument, Line, and Speaker. It allows you to connect various audio sources to a mixing console or PA system.
How do I power the Trimode?
You can power the Trimode via 48V phantom power from the XLR output or with a standard 9V battery (not included). The unit automatically switches to battery if phantom power is not present.
How do I select the different modes?
Use the rotary switch on the front panel to choose between Instrument, Line, or Speaker mode. Each mode optimizes the input impedance and level for the respective source.
What is the ground lift switch for?
The ground lift switch disconnects the audio ground from the chassis ground, helping to eliminate hum and buzz caused by ground loops.
Can I connect a speaker output to the Trimode?
Yes, in Speaker mode, the Trimode can safely accept speaker-level signals from an amplifier. It then converts them to a balanced line-level output for the mixer.
What type of battery does the Trimode use?
The Trimode uses a standard 9V alkaline battery. It is recommended to remove the battery when using phantom power to prolong battery life.
Is the Trimode compatible with keyboards and synthesizers?
Absolutely. Use Instrument mode for keyboards and synths with unbalanced outputs. The high input impedance preserves tone and signal integrity.
How do I clean the Trimode?
Clean the unit with a soft, dry cloth. Avoid using liquids, solvents, or abrasive cleaners that could damage the chassis or electronics.
What does the pad switch do?
The -15 dB pad attenuates the input signal by 15 decibels. Use it when connecting hot line-level sources to prevent clipping and distortion.
Does the Trimode come with a warranty?
Yes, Radial Engineering offers a 3-year limited warranty against defects in materials and workmanship. Register your product online to activate the warranty.
