Names of Things and What They Do
2 Digital Input
Coaxial Input Connector (Digital Input)
This is the digital input connector for coaxial cable.
NOTE
It cannot be used for input of analog audio signals (no sound is
produced).
Optical Input Connector (Digital Input)
This is the digital input connector for optic-fiber cable.
Use commercially available optical cable for audio
equipment to make the connection.
NOTE
Optical-connector Protective Cap
• After removing the protective cap, put in a safe place
so that it doesn’t get lost.
• When not using the optical connector, attach the cap
to keep the connector safe.
• When using the optical connector, be sure that the cap
you removed is placed out of the reach of children. If
a child has accidentally swallowed a cap, see a doctor
immediately.
Digital Input Select Switch
This switch selects Optical or Coaxial. Select the
connector used for the input signal.
Assign Switch
This switch selects the stereo position of the digital signal.
It selects Right, L+R, or Left when using two DS-50A
monitors for stereo sound (with digital signals).
Choose the setting appropriate for your setup.
MEMO
With the DS-50A, there is no difference between L and R.
When using the digital input connectors of two DS-50A
monitors for stereo sound, the digital signal can be input
to either L or R.
3 Input Select Switch
Used to select Digital Input or Analog Input.
Select the connector used for the input signal.
4 Thru (Digital Out) Connector
When connecting multiple DS-50A monitors with digital
signals, this connector is used for output to the second
DS-50A.
Refer to “Connection Examples” (p. 8, 9).
5 Level Control
This adjusts the input level. Turning the control
clockwise increases the sound from the speakers.
6 HF Trim Control
This adjusts the sound quality of the treble range
(10 kHz, +/-3 dB).
7 LF Trim Control
This adjusts the sound quality of the bass range
(80 Hz, +/-3 dB).
MEMO
The LF Trim and HF Trim controls on the DS-50A are
designed to correct the sound quality of the sonic field.
Use these to make fine adjustments to match the usage
conditions.
8 Power Switch
This switch turns the power on/off.
NOTE
• Before turning the power on or off, you must lower the
volume of this unit and your connected device etc.
• This unit is equipped with a protection circuit. A brief
interval (a few seconds) after power up is required
before the unit will operate normally.
9 AC Inlet
Connect the included Power cord here. Plug it firmly in,
so that the cable does not accidentally become
disconnected.
10 Heat Sink
This is a heat-radiating plate that dissipates excess heat.
