the DX4’s speaker output. When headphones are plugged into this jack, the
DX4 speakers are muted and headphone volume is controlled using the
volume control.

Rear panel contains only a single Speaker Terminal, for connectioin to the
Speaker Terminal of this (Left) Speaker.
1. RCA Line INPUTS (L & R) - There are two RCA Line Inputs, marked as follows:
“L” - Left Channel Input (white jack) &
“R” - Right Channel Input (red jack).
These jacks accept standard RCA input connections with unbalanced wiring.
The included 1/8-inch mini jack-to-RCA audio cable allows users to connect the
DX4s to other equipment accepting 1/8-inch mini jack connections.
2. TRS INPUTS (L & R) - There are two RCA Line Inputs, marked as follows:
“L” - Left Channel Input &
“R” - Right Channel Input
These jacks accept a 1/4” connection with either balanced or unbalanced wiring.
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’s
negative input. A three-conductor (TRS) plug, wired unbalanced, provides the
option of leaving the negative input open or grounded. We recommend
grounding the unused negative input, which can be done by wiring the ring
and sleeve of the TRS plug together.
