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. 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.
4. Acoustic Space Switch: Your DN-306S 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-306S 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.
5. Volume Control: Use the volume control to set the output sound pressure from the
DN-306S 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.
