MASS-Kobo Model 465

MASS-Kobo Model 465

The Model 465 is designed with independent left and right power, creating a twin balance monaural configuration. This unique design enhances the audio experience by providing a clean and stress-free sound, where the presence of the amplifier is virtually undetectable. It delivers a flagship sound quality that surpasses expectations.

In terms of output, this amplifier offers balanced output of 3.5 W + 3.5 W (32 Ω load), ensuring sufficient power to drive compatible devices. The input options include Balanced XLR 3-pin and Unbalanced RCA, catering to various connectivity needs.

When using the Balanced input, it's important to note that the reference input level can be selected between +4 dBm and -10 dBm. This feature allows you to optimize the input level based on your specific setup and equipment requirements.

It's crucial to maintain the appropriate connection between devices to ensure optimal audio performance. If you connect a device with an unbalanced output to a balanced input, the output will not remain balanced. Therefore, it's recommended to connect devices with unbalanced outputs to the RCA input terminals to maintain the intended balance.
