The Theater Amplifier Standard is a five-channel power amplifier boasting our latest circuit topology and a substantial power output of 200 Watts per channel into 8 Ohms (400 Watts per channel into 4 Ohms). The elegant Krellcoat exterior houses the technology developed in the Krell Full Power Balanced amplifiers including a gigantic power supply, Krell Current Mode circuitry, and balanced operation. The Theater Amplifier Standard is the reference multi-channel amplifier for systems that are used for stereo or multi-channel music and movie playback.

Power Supply
Two 1400 Watt toroidal transformers and 109,000 microfarads of filter capacitance make up the massive 2800 Watt power supply that is the engine of the Theater Amplifier Standard. The power supply is configured to provide the entire capacity of the transformers to any of the channels at any time. A design that uses smaller individual transformers, while cheaper, limits each channel to its own transformer's lesser capability. If a channel's demand exceeds its own power supply's capability, the music suffers. With one common power supply, there is additional power available whenever a channel needs it -- the music is never compromised.

Power Output
Today's multichannel music and movie soundtracks place tremendous stress on amplifiers. Each Theater Amplifier Standard output channel employs ten output and four driver devices to deliver the exact power required by the speakers under any demand. All speakers benefit from greater power, the more the better. The Theater Amplifier Standard outputs 200 Watts into 8 Ohms and 400 Watts into 4 Ohms. Additionally, any two adjacent channels can be bridged into a monaural amplifier with an 800 Watt (8 Ohm) output.

Circuitry
Featuring circuitry sourced from the Full Power Balanced amplifiers, the Theater Amplifier Standard includes technology previously incorporated in the reference level components only. The circuit topology is executed with Krell Current Mode circuitry featuring balanced topology for the lowest noise and true insight into the recording. Class A input, pre-driver, and driver stages provide the most accurate signal path for critical low level signals. Surface mount technology is utilized for maximum circuit density resulting in the widest dynamic range and bandwidth possible. Class A input, pre-driver, and driver stages provide the most accurate signal path for critical low level signals. The amplifier circuitry also features exceptionally low negative feedback for improved clarity and detail resolution.
