● Analog Input
In addition to an XLR connector, which provides for
balanced input, a 1/4" TRS phone jack accommodating either balanced or unbalanced input
is also provided. This assures broad-ranging connectivity.
● Digital Input
The DS-30A is provided with digital input connectors (coaxial and optical) that support 96
kHz sample rate and 24-bit digital audio.
Digitally input signals are reproduced faithfully through 24-bit D/A conversion, thus
preventing noise or a drop in sound quality.
You can use the monitors with a wide variety of equipment and applications through
selective use of the analog and digital settings.

Input or Analog Input).
• Make sure the Digital Input select switch has been set to
the connector where the input signal is connected
(Optical or Coaxial).
• Input a digital signal to the Digital Input connector. No
sound is produced when an analog signal is input.
926
The volume level of the instrument
connected to ANALOG INPUT is too
low
• Could you be using a connection cable that contains a
resistor? Use a connection cable that does not contain a
resistor.
