Install-friendly amplifier puts power where you need it
SpeakerCraft's Vital 1250 multi-channel amplifier offers versatile setup flexibility and plenty of clean, high-quality power when and where you need it, for top-notch sound. You can customize this powerful 12-channel amp to best suit your specific multi-room applications. Enjoy clear stereo sound in six rooms, or combine two channels into one to give your speakers more juice — a great option for power-hungry outdoor speakers. Use a single channel of power for mono sound in smaller listening areas, like a walk-in closet or bathroom.
More flexible options for enjoying music throughout your home
The Vital 1250 can distribute music from one audio source, such as a networked music streamer, to multiple rooms in your home. Or you can connect additional sources directly to the individual amplifier channels and assign each one to a single listening room. Each channel features its own separate level control so you can easily adjust the volume to fine-tune the sound of your system.

Overview: The SpeakerCraft Vital 1250 amplifier delivers the power and fidelity needed to distribute music throughout your home. This amplifier includes the necessary features needed for flexible, reliable custom installation. Sophisticated design and superior internal components, result in outstanding sound quality, performance, and long term reliability.
50W x 12Ch Amp: The SpeakerCraft Vital 1250 amplifier is rated at 50 watts x 12 channels (in 8Ω at 20-20kHz with 2-channels driven and 0.40% THD), or 75 watts x 12 channels (in 4Ω at 1kHz with 2-channels driven and 0.50% THD).
Bridgeable: The power output of adjacent amplifier channels can be combined to provide extra power when needed in certain locations & applications. This is easily accomplished by flipping a single switch on the amplifier's rear-panel. Bridged power rating of the amplifier is 170 watts x 6 channels (in 8Ω at 1kHz with 2-channels driven and 0.50% THD)
Binding Posts: The SpeakerCraft Vital 1250 amplifier is fitted with gold-plated, binding posts for each channel. The binding-post terminals will accept bare-wire (up to 10AWG), pin-connectors, and banana plugs (dual or single).
Flexible Input Selection: Each of the amplifier channels can be assigned a variety of source inputs; a dedicated input can be assigned to each channel or each channel can be configured to play common signals from the Bus or Auxiliary inputs. This provides the flexibility needed in sophisticated custom audio installation.
- Bus Input: The Main bus input (stereo RCA) allows outputs from receivers, CD players, TVs or an stereo audio sources to be amplified across all channels of the amplifier for easy multi-room applications.
- Aux Input: The Auxiliary input (stereo RCA) allows an additional audio source to be played on any channels that are switched to AUX.
- Dedicated Channel Inputs: Individual channels inputs (mono RCA) allow you to connect different audio sources to each channel of the amplifier.
Note: When either a Bus or Aux input is selected, there is a switch on the rear-panel used to direct the channel to play the left signal, the right signal, or a combined right and left signal from that amplifier channel.
Bus & Aux Outputs: The Bus output (stereo RCA) allows the Bus input of the amplifier to be sent to another amplifier in your system. The Auxiliary output (stereo RCA) allows you to daisy-chain the amplifier's input to other amplifiers in your system.
Channel Level Adjustment: Each channel has its own level adjustment. This allows the loudness of each speaker to be perfectly matched to its location and application and balance your system's sound.
Protection Circuitry: Each channel of the amplifier is individually protected. If the advanced circuitry determines that a channel must be shut down for protection (a rare occurrence) only the channel affected will be turned off, while the other channels continue to play. Once conditions return to normal, the affected channel will be turned back on and operate as normal.
Note: When the Protection LEDs (Red) on front of the amplifier are lit, it is indicating either a fault in the wiring, the speaker, or the amplifiers of that particular channel.
Power Modes: There are three ways to turn the amplifier on; Constant, Trigger, or Audio Sense. This allows the amplifier to operate seamlessly as part of a sophisticated custom installation. The 3-way power mode switch is located on the amplifier's rear-panel.
- Constant: Select Constant mode when you wish to manually turn the amplifier on and off by using the front mounted power button.
- Trigger: Use Trigger mode if you prefer the amplifier turn on when it receives voltage (3-30V) from an external source and turn off once that voltage has stopped. The voltage source must be connected to the trigger input jack (3.5mm) on back of the amplifier.
- Audio Sense: Audio Sense mode turns on the amplifier when the amp's main input receives an audio signal. Once the signal stops, the amplifier waits 3 minutes and then turns itself off.
Trigger Output: A separate output trigger (2.5mm) allows the amplifier to activate other components via a 12-volt trigger.
Rack Mountable: The amplifier includes a set of rack ears for rack mounting applications.
