1. XLR Input: This jack accepts XLR input connections
with either balanced or unbalanced wiring. The input
wiring of an XLR connector should be as follows:
• XLR Pin 1: signal ground (shield)
• XLR Pin 2: signal positive (+)
• XLR Pin 3: signal negative (–)
2. TRS Input: This jack accepts 1/4" connections with
either balanced or unbalanced wiring. For balanced
wiring, a three-conductor TRS plug is necessary. The
input wiring of a TRS connector should be as follows:
• TRS Tip: signal positive (+)
• TRS Ring: signal negative (–)
• TRS Sleeve: signal ground (shield)
Unbalanced 1/4" wiring can be done with either a two-
or three-conductor (TS or TRS) plug. A two-conductor
(TS) plug automatically grounds the signal negative
input, whereas a three-conductor (TRS) plug, wired
unbalanced, provides the option of leaving the negative
input open or grounded. We recommend that you
ground the unused negative input (this can be done by
wiring the ring and sleeve of the TRS plug together).
The TRS input is summed through a balanced input
amplifier with the XLR input, allowing both inputs to be
used simultaneously. Input specifications apply to both.
3. Acoustic Space Switch: Your DN-308S loudspeakers should ideally be placed at least one foot away
from the nearest wall, ceiling, or other large, flat surface. In the real world, this may be impractical due
to space limitations. For that reason, DN-308S loudspeakers feature an acoustic space switch. This
switch compensates for placement near walls where bass response is affected by its proximity to
other objects.
Tip: Be sure to leave at least 3" of space between the rear of the loudspeaker and a wall to allow the
rear-firing port to "breathe" properly. Placing the loudspeaker any closer than 3" may adversely affect
low-frequency response.
4. Sub-Frequency Vent Port: This port aids in reproduction of very low frequencies by discharging
frequencies below 60 Hz and to act as a cooling mechanism to prevent overheating. This port should
not be blocked.
5. Volume Control: Use the volume control to set the output sound pressure from the
DN-308S to proper levels as required.
6. Power Switch: This switch turns the loudspeaker on and off. The "auto-power" feature will go into
low-power "eco" mode if there is no signal present for about 12 minutes. To "wake" from low-power
mode, send an audio signal to the speakers.
7. Power Receptacle: Accepts a detachable 3-circuit line cord in order to power the loudspeaker.
8. Fuse Holder: Holds the external main fuse.
9. Voltage-Select Switch: Provides two selections, 115V AC and 230V AC, and should be set to match
the "house supply" (receptacle) voltage of the country or location in which the loudspeaker is used.
The 115V setting is correct for the USA, while the 230V setting is correct for most of the UK and
Europe.

Front Panel

1. Power LED (front panel; not pictured): The power indicator illuminates when the loudspeaker is
receiving power and the rear panel Power Switch is in the "ON" position.
2. HF Driver (tweeter) (front panel; not pictured): The high-frequency driver outputs the top range of the
audio spectrum.
3. LF Driver (woofer) (front panel; not pictured): The low-frequency driver outputs the bottom range of
the audio spectrum.
