Overview

CMX6208SP is an integrated active subwoofer. It has built-in DSP audio processor and 3- channel ampliﬁer. The 800W channel powers the internal subwoofer and the other two 280W channels can power external speakers such as CMX6903, CMX6403 or CMX6203 as system solution. The built-in DSP processor includes compressor, limiter, noise gate, parameter equalizer, matrix routing, delay and preset. CMX6208SP allows central multiple device management networking through USB, TCP/IP and RJ45, as well as audio transmission through Dante. System with CMX6903, CMX6403 and CMX6203, it provides ﬂexible conﬁgurations for diﬀerent applications. For example, conference rooms, multifunction halls, rental PA sound reinforcement.

Panel Function Descriptions

Display screen: 1.5-inch LCD colorful display screen, 240*240 pixels.
Function navigation: rotate to the left to decrease the volume of INPUT A/B, and rotate to the right to increase the volume of INPUT A/B. Press: enter the function menu and conﬁrm; rotate: select and change a value.
Protection indicator (red): when a module temperature exceeds 75°, the LED is turned on.
Clipping indicator (yellow): the indicator is turned on when the input level is ≥8dBu (the volume knob is at the maximum volume position).
Signal indicator (green): the indicator is turned on when the input level is ≥-52dBu.
RJ45 port: this RJ-45 connector is used to connect the product to a network or PC. Then the product can be conﬁgured and controlled, and you can also update the module to the latest ﬁrmware from the PC. Dual network port control, DANTE input ports, regardless of primary and secondary ports, and supporting LINK (this Dante interface has a receiving function only, with no transmission function).

LINK OUT A/B output interface: balanced XLR-Male.
INPUT A/B input interface: balanced XLR-female “Phone Jack, with the input impedance of 20KΩ.
Volume knob A/B: control the gain of the input preamp, rotate the button to the left to control the gain of the INPUT A/B preamp to decrease until -∞; and rotate the button to the right to control the gain of the INPUT A/B preamp to increase until 0dB, and in this case, the maximum input level is 8dBu. When the knob is at the middle position, the gain of the INPUT A/B preamp drops by 8dB, and in this case, the maximum input level is 16dBu.

Installation

Before installing the subwoofer, please inspect whether all hardware, hangers, cabinets, sensors, brackets, and associated components are damaged or not. Any missed, corroded, deformed, or unloaded rated components may greatly reduce the safety of the location. Any such situation can seriously reduce installation safety and should be corrected immediately. The limitation of hardware or devices shall never be exceeded. For installation of physical devices, please consult licensed professional engineers. Please ensure all local and national regulations are known and followed for safety and operation of the speaker and related devices.

□Note: when the CMX6903 is installed on the top of the CMX6208SP, a base must be used at the bottom of the CMX6208SP. The base needs to be purchased separately, please contact your local dealer.
Note: all connection wiring should be carried out when the power supply is disconnected.
When the CMX6903 is plugged into the top of the CMX6208SP, the CMX6903 will be automatically connected to the EXT CH1. In this case, if you intend to extend the connection to other CMX series sound columns, they should connect to EXT CH2 instead.
When the CMX6903 is not connected to the CMX6208SP, the EXT CH1 and EXT CH2 can be connected to the CMX series sound columns simultaneously. JBL

8.2 Input port wiring
Balanced input: connect to a plug as shown JBL CMX6208SP Integrated Active
Subwoofer - fiig 5 Unbalanced input: connect to a plug as shown. If a 3-core (XLR) plug is used to connect an unbalanced sound source, pin 3 and pin 1 must be connected to jumpers as shown.

8.3 Output port wiring
Before output connection is established, please ensure that the product’s power cable is completely disconnected and inspect the total impedance of all speakers at all output. If multiple speakers are connected to the output (that is, in series, in parallel, or in seriesparallel), in a low impedance mode, please ensure that the total system impedance is within the channel speciﬁcation.
Cable speciﬁcations are determined according to the following wiring guidelines, depending on a distance between the power ampliﬁer and the speaker.

Distance:	Cable speciﬁcation:
Within 25 ft.	16 AWG
26-40 ft.	14 AWG
41-60 ft.	12 AWG
61-100 ft.	10 AWG
101-150 ft.	8 AWG
151-250 ft.	6 AWG

Note: never use shielding cables for output wiring.
Use the following method to connect a stereo speaker to the Speakon® connector:
Insert CMX6403/CMX6203 into the Speakon® interface of the EXT CH1 (upper), and CMX6403/CMX6203 into the Speakon® interface of the EXT CH2 (lower).
