14) Refer all servicing to qualified service personnel. Servicing is required when the apparatus has
been damaged in any way, such as power-supply cord or plug is damaged, liquid has been

2
spilled or objects have fallen into the apparatus, does not operate normally, or has been
dropped.
15) DO NOT ATTEMPT TO OPEN THE AMPLIFIER ITSELF; IT IS NOT USER-SERVICEABLE.
i. WARNING:The loudspeaker is supplied with an AC mains power cable. Depending on the
voltage model ordered, this cable is configured with the most common ac mains connector
for that voltage. If the connector is not compatible with the local ac mains receptacle,
employ a licensed electrician to re-configure the cable with the proper connector. Ensure
that ac power supply has a properly grounded safety ground. Failure to follow this warning
could cause equipment damage, injury, or death.

RS™ System Overview
RS is the newest powered point‐source loudspeaker from EAW. Drawing from EAW’s rooted legacy as a
manufacturer of high‐end touring loudspeakers, RS is designed specifically for the professional audio users in
corporate AV, rental & staging, and installation. RS Series consists of four two-way, point source models (RS121,
RS123, RS151, & RS153) and two subwoofers (RS115 & RS118).

Unpacking
You should have visually inspected the outside of the shipping carton and noted any damage on the shipping
bill you signed. After unpacking, if you find concealed damage to the loudspeaker, save the packing materials
for the carrier's inspection, notify the carrier immediately and file a shipping damage claim.
Although EAW will help in any way possible, it is always the responsibility of the receiving party to file any shipping
damage claim. The carrier will help prepare and file this claim.

Functions and Operations
RS 121, 123, 151, 153 Rear Input Panel Diagram
1. Level (Gain) Control
Adjusts the level of the INPUT signal. Turning counterclockwise will reduce the output level and
turning clockwise will raise the overall output level of the speaker.
2. XLR Input Connector
Balanced XLR input connector for analog input signal.
3. XLR Thru (Output) Connector
Balanced XLR output connector to daisy-chain input signal to other speakers. This signal comes
directly from the input signal and is unaltered by speaker’s internal processing.
4. Balanced TRS Connector
Balanced 1/4” TRS input connector for analog input signal.
5. Line/Mic Switch
This switch controls the input sensitivity. For low-voltage signals, such as from a microphone, set the
switch to the MIC position. For high-voltage signals, such as from a mixing console, set the switch to
the LINE position.
NOTE: Utilizing the MIC switch position with a high-voltage signal may cause damage to your speaker –
be sure to use the proper switch settings based on the incoming signal strength.

6. Main/Monitor Button
This button is used to toggle between the speaker’s two pre-defined voicings – MAIN and MONITOR.
The MAIN voicing should be chosen when the speaker is placed on a tripod or installed. The MONITOR
voicing should be chosen when the speaker is placed on the floor or at its monitor angle – this setting
reduces the impact of low frequency floor coupling that occurs when a speaker is placed on the floor,
providing a cleaner and more coherent output.
7. Status LED Indicator
The status indicator will remain lit if the speaker is in functioning condition. If the light blinks, it
indicates that the speaker has entered temperature protection mode and must be cooled down and
power-cycled before it will function normally.
8. Signal LED Indicator
The status indicator will turn green when an input signal is detected. NOTE: Low-voltage signals may
not be able strong enough to trigger the LED indicator, but may still be heard from the speaker – this
is perfectly fine.
9. Limit LED Indicator
The limit indicator will turn red when the output has reached its maximum level. If the LED blinks
occasionally, EAW DynO™ will optimize the output and continue to provide clear output at its
maximum volume. If the LED blinks frequently or is lit continuously, reduce the level control (1) to
prevent output distortion.
NOTE: Only one signal input may be used at a time (2 or 4) – using both at the same time will result in a
distorted signal.
