INTRODUCTION
Thank you for your purchase of the MA258.The MA258 is intended for high end
audiophile speakers or headphone listening. It has a FR4(V94-0) rated glass
epoxy circuit board, and a powder coated all steel chassis. It is designed to last.
OPERATION
The MA258 was designed to have the highest level of sound quality, whether
you are using it as a headphone amp or with speakers. At every design stage we
spent a considerable amount of time focused on one thing, sound quality.
The inputs and outputs of the MA258 are self explanatory. Plug a signal in, select
the source, and connect to your desired headphones or speakers.
One thing to note about the MA258 is the speakers are the default output. When
you plug Headphones into the headphone jack on the front of the unit. The power
amp section is then completely disconnected from the circuit. Meaning that when
using the Headphone output of the MA258 the unit is only a headphone amplier.
