At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Overview: JL Audio CleanSweep CL-SES is a high-quality audio source
switch that allows you to select from up to three input devices via automatic
signal sensing or a manually operated switch. This gives you the freedom to
install your choice of audio sources, without resorting to weak sounding FM
modulators or cassette adaptors. The CL-SES can be used to expand the auxiliary
input capabilities of the CleanSweep CL441dsp or any head unit that provides an
auxiliary line-level input, including many OEM head units.
Differential-Balanced RCA Inputs: The CL-SES utilizes
differential-balanced RCA inputs to provide superior noise immunity and ensure
compatibility with a wide range of source units.
CMOS Switching: Advanced, solid-state CMOS switching ensures clean,
distortion-free audio with no mechanical contacts to wear or corrode. Switching
between source unit can be accomplished via automatic signal sensing or a
manually operated witch which is included with the CL-SES Source Expander Switch
- Automatic Switching Mode: Automatic Mode uses signal-sensing to
switch between source units plugged into the CL-SES interface. You determine
which source units have priority over others by plugging them into to the
appropriate inputs on the CL-SES and then select between them simply by
turning them on or off. When switching from an higher priority source to a lower
priority source the CL-SES will delay switching by 10-12 seconds. This
prevents undesired switching during quiet passages in a track and/or
silence between tracks. If a track has an unusually long quiet passages
or a very long fade in or fade out, the CL-SES may switch unexpectedly.
- Manual Switching Mode: Manual Mode uses the included remote
push-button to switch between source units. When you are finished with a
particular source, press the switch to go the next source. Active inputs
switch in sequence from A to B to C and then back to A. In Manual Mode, the CL-SES will remember the last Aux
Input source selected when the vehicle is turned off and return to that
source when the vehicle is restarted. The push-button
switch features an attached 6' cord terminated by a male 3.5mm minijack
connector which plugs into the CL-SES expander. The push-button switch is
designed to be flush mounted to a flat surface of your vehicle such as the
dash or console within reach of the driver. The outer diameter of the switch
measures 0.557" while the cut-out diameter measures 0.493". The cut-out
depth of the switch measure 0.4375".
Level-Trim Controls: Level-Trim controls are provided for each input
to aid in achieving equal sound levels between sources plugged into the CL-SES
expander module and your headunit. If your AUX source unit gives you the option of a fixed
line-level output or a variable output (controlled by its volume
control), use the fixed line-level output for best fidelity.
LED Indicators: Each input has a corresponding LED indicator (located
on the top panel of the CL-SES) to indicate when it is the active input.
Connections: The CL-SES features the following connections.
- Power Connector: The CL-SES has a three-wire inline jack which
connects to the supplied power/ground harness. The harness features a Ground
lead, +12V Switched Power lead, and a +12V Constant Power lead. Since the
CL-SES does no draw much current during operation, 18 AWG to 16 AWG wire is
ample for making all of these connections.
- Manual Override Connector: To operate the CL-SES in Manual Mode,
connect the included push-button switch to this 3.5mm minijack port.
- Output Connection: Two RCA-type jacks provide two-channels of
analog audio output to feed the auxiliary input of your headunit or OEM
Interface Processor. You will need either a stereo RCA cable (sold
separately) or Mini to Stereo RCA cable (sold separately) to make this
connection depending on auxiliary input of your headunit or OEM Audio
- Input Connections: The CL-SES accepts up to three separate stereo
input sources via six RCA-type jacks located on one end of the main chassis.
The input architecture is setup in a differential-balanced configuration,
making these inputs compatible with virtually any analog audio signal. To
connect an auxiliary source, you will need standard RCA-type audio
interconnect cables (not included). For sources that use a 3.5mm minijack
plug you will need a Mini to Stereo RCA adapter cable (sold separately). The
input connections on the CL-SES are labeled as follows - AUX INPUT A (first
priority), AUX INPUT B (second priority), and AUX INPUT C (third priority).
