T-118 Amplification

T-118 (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.

T-118 AMPLIFER CHANNELS

Amplifier Channel One: When installed into a T-118, amp channel one will power that subwoofer along with a second non-powered subwoofer. To power the second subwoofer, connect the NL4 from the powered cabinet’s “Output 1″ to the non- powered cabinets “Input.” This creates a 4 ohm load on amp channel one.

Amplifier Channel Two: Amplifier channel two is wired directly to NL4 “Output 2″ on the rear panel of the speaker cabinet. “Output 2″ is only used when an internal power amplifier is installed into the cabinet. Users have multiple options on powering additional T-Series cabinets with “Output 2.” See the diagrams below.

**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 for each amplifier 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.

**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.
