Quick Start 1. Connect the included JBL power supply to the POWER jack on the rear panel of the mixer. 2. On the front panel of the mixer, switch the POWER switch to the on position. 3. Connect a stereo audio source to the SOURCE 1 input. Do not put any audio through the mixer at this time. 4. Turn the SOURCE 1 GAIN knob, on the rear panel of the unit, all the way counter-clockwise. 5. Turn the ZONE 1 LEVEL knob, on the front panel, all the way counter-clockwise. 6.
1.0 Introduction 1.1 JBL Commercial CSM-21 and CSM-32 Mixer ® The JBL Commercial CSM-21 and CSM-32 mixers (hereafter referred to as ‘mixer’) were specifically designed to provide signal routing flexibility and multiple audio source control. To facilitate this, JBL has equipped the mixers with a wide array of input and output capabilities. These features allow you to bring the same audio quality – that many of your patrons are used to hearing at home – into your place of business.
2.0 Installation Method 1 - Attaching the brackets to the front panel for rack mounting Method 2 - Attaching the brackets to the sides of the unit for wall mounting 2.1 Unpacking This product was carefully inspected before packing to ensure flawless appearance and operation. Please unpack and inspect your CSM mixer for any damage that may have occurred during transit. If damage is found, notify the transportation company immediately. Only you can initiate a claim for shipping damage.
2.4 Audio Input and Output Wiring Convention Balanced wiring - The convention for balanced wiring (2-wire plus shield) is: Input + Input - GND Shield Unbalanced wiring - The convention for unbalanced wiring to the inputs (1-wire plus shield) is: Input + GND Shield NOTE: THE ABOVE WIRING CONVENTIONS ARE APPLICABLE FOR THE FOLLOWING CONNECTORS: MIC INPUT, DIRECT INPUT, ISO AUX OUTPUT AND ZONE OUTPUT.

Firmware Update The USB connector allows you to connect your computer to the mixer for updating the firmware. To retrieve the firmware version of your mixer, observe the LEDs on the rear panel while the mixer boots. The LED in the SOURCE 1 section represents major.
6. Zone Remote Jacks These inputs are for the optional remote controls: CSR-V, CSR-2SV, and CSR-3SV. 7. Isolated Auxiliary Output* This output sends a transformer isolated mono signal for a music-on-hold system, or for a separate mono auxiliary zone (please note that paging and emergency announcements will not be sent to this zone). The +/- outputs are 600 Ohm transformer isolated so that they can interface to another system (telephone or remote amplifier) without having undesirable ground interaction.
13. Priority Hold Priority Hold smoothly adjusts the time it takes for the normal, or ducked, input source to become audible again after the priority source ceases. This allows for compatibility with the many different types of priority sources that exist in business environments. 14. Microphone Input Connect the paging microphone here.

Source Selector The SELECT knob selects which source is fed to each zone, or selects the REMOTE option – when using a remote control for source selection. To activate remote source selection control, this control must be set to the REMOTE position. 2. Source Level Knob This LEVEL knob increases or decreases the output level of the background music.
7. Bass Mic EQ The Bass trim pot applies cut or boost, by up to +/-6 dB, to the Microphone’s low frequencies. 8. Treble Mic EQ The Treble trim pot applies cut or boost, by up to +/-6 dB, to the Microphone’s high frequencies. 9. LevelGuard™ Threshold This LED flashes amber when the LevelGuard™ function has been triggered. This threshold pot adjusts the point at which LevelGuard™ will kick in. 10.
5.0 Knowing Your Mixer 5.1 Source What is a Source? This is a line-level input signal such as programmed music, CD player, VCR/DVD, satellite feed, tape player, radio, message repeater, or juke box. These sources are then equalized, dynamically controlled, and routed by your selections and priorities on the mixer. 5.2 Zones What is a zone? This is the area where you wish the signal to be heard. The mixer outputs a stereo or mono signal to your chosen zone.
6.0 Setup 6.1 Determining Source Priorities Determining the hierarchy of your sources is easier than it sounds. Generally, it follows this order: 1. Emergency/Alarm (Direct Input with MUSIC MUTE engaged) 2. Pages (Paging Mic) 3. Prerecorded announcements (or another source into SOURCE 1 with Priority engaged). 4.
6.5 Using the Subwoofer Crossover When the XOVR switch is engaged, the main speakers are high-passed at 125 Hz and the subwoofer outputs are low-passed at 125 Hz (both using a Butterworth 24 dB per octave filter), forming a full subwoofer crossover. When the XOVR switch is NOT engaged, the main speaker outputs and the subwoofer outputs will all pass a full-range signal. 6.6 Setting Up AutoWarmth™ Method 1 To set up AutoWarmth™, begin by turning the AutoWarmth™ trim pot to the twelve o’clock position.
6.8 Setting Up LevelGuard™ To set up LevelGuard™, begin by turning the LevelGuard™ trim pot to twelve o’ clock. Use this as your “baseline” setting. Now turn up the Source volume to the level desired for a particular zone. Check the LevelGuard™ indicator LED, on quieter passages the indicator should be off. On peak volumes the indicator should flash amber. If the indicator is constantly on, turn the trim pot clockwise until it flashes only occasionally.

Optional Item - CSR Series Remote Controls CSR-V CSR-2SV CSR-3SV Compatibility Between CSR Remote Control and CSM Mixers Remote Control CSR-V CSR-2SV CSR-3SV Mixer CSM-21 CSM-32 Q Q Q Q* Q *when using two input sources Optional remote controls are available from JBL to provide source selection and volume control from a remote location other than your mixer.
Controlling Volume The LEVEL on the mixer is ALWAYS operational, regardless whether the Source Selector function is active or not. This remote control is ATTENUATE ONLY. To set the volume control of the remote control, you can follow these steps: 1. Turn the remote control LEVEL to maximum (full clockwise). 2. Set the volume control on the mixer to the loudest you will ever need the system to be. 3. Turn the remote control LEVEL knob down to a comfortable or typical operating level.
