The original Tundra Mono was developed from our stereo power amplifier Tundra and shared many of its qualities. Tundra Mono has only one channel and is therefore more powerful, but the main difference is that sound quality is even higher. Regardless of whether you play quiet or loud, the music becomes more alive and engaging to listen to.
Four important details make the single channel Tundra Mono better than Tundra:
1. The twin power supplies are of the same type as in Tundra, but in Tundra Mono they only have one channel to drive. This makes them run smoother and all the circuits of the amplifier gets cleaner voltages to work with.
2. The drive stage that handles the output is five times as powerful. This makes Tundra Mono less bothered with how much current the loudspeaker needs.
3. The cooling of important components has been improved. This makes Tundra Mono more stable when the music goes from silent to loud.
4. The circuit board has thicker tracks of copper and is mechanically more optimally secured. Just like in the stereo version of Tundra, all fasteners are tightened with torque tools to just the right torque. But in addition, new securing points were added to Tundra Mono after listening tests.
Every Tundra Mono is individually fine tuned. This requires a run in period, measurements and evaluation with music. The fine tuning process is time consuming and currently limits us to producing one Tundra Mono per day. Only if it performs as well or better than our reference will it get packed down and shipped to the customer.
