T-215 Amplification

T-215 (500 series) 2 channel amplifier module

Installation Process

When installing the amplifier pack, remove the passive panel on the back of the enclosure by un-screwing the t-nut bolts. Once the passive panel has been removed, connect the amplifier by following the simple color coded diagram provided. Once the amplifier has been properly connected, slide the amplifier module into the enclosure and secure with the t-nut bolts.


Amplifier Channel One: When installed into a T-215 it will power that loudspeaker at a 4 ohm load. To power a second loudspeaker, connect the second loudspeaker to “Output 2” and NEVER patch into “Output 1” when using an internal amplifier. “Output 1” is only used when the T-215 is powered by external power at a 2 ohm load.

Amplifier Channel Two: Amplifier channel two is wired directly to NL4 “Output 2” on the rear panel of the speaker cabinet. “Output 2” will power a second T-215 loudspeaker or two T-118 subwoofers at a four ohm load.

**Note: The amplifier will be pre-tuned to a chambered flat response curve that is specific, per channel, for the models it will be used with. Users can make DSP, gain, delay and other adjustments through the amplifier control software, “TVi Control.” Each amplifier has a single signal input / output so gain and DSP adjustments between channels must be adjusted and stored within the amplifier’s control software that can be accessed easily with a laptop computer.

Powering Combinations
Diagram [A]

A single internal amplifier powering two T-215 loudspeakers at a four ohm load per channel (Note: “Output 2” powers the second loudspeaker).


Diagram [B]

A single internal amplifier powering one T-215 loudspeakers & two T-118 subwoofers at a 4 ohm load per channel.


**Note: Each amplifier channel may also operate at an 8 ohm load, so the diagrams above only show the maximum number of T-Series cabinets that can be powered using a single internal amplifier. Each user’s application is different and may require fewer cabinets per amplifier channel.
