The MONO BLOCK power amplifier was created using a simple yet meticulous design that appropriately captures the INDIGO Series ambience. We have maximized the benefit of having a configuration of two large monaural chassis to achieve clear sound reproduction in line with INDIGO’s sound policy when combined with the INDIGO LINE-Amplifier. Even when connected to a non-INDIGO LINE-amplifier, it produces such uncolored, high-resolution sound of such depth and tangibility that the expressive power of the pre-amplifier is exposed for better or worse.
At the input stage, in order for the entire music signal to be amplified and to suppress intermodulation distortion, lower impedance and facilitate a smooth transfer to the next signal stage, the highest possible level of amplification precision is enabled. At the output stage a power operational amplifier, which is capable of flat amplification down to 0 Hz, was used to measure the output increase.
The MONO BLOCK having these features, we recommend using it in conjunction with the INDIGO LINE-Amplifier. When purchasing this product together with the LINE-Amplifier, we assume they will be used as a pair. Therefore, after receiving your order, our experienced technicians will begin mounting parts and assembling both the Pre-Amplifier and the MONO BLOCK at the same time. After assembly is complete, the product will undergo in-house testing for approximately 2 weeks before it is shipped. Therefore, please note that it will take approximately 50 days from the time we receive your order until delivery.
