Frequently Asked Questions - CSM-32 JBL

How should I clean the JBL CSM-32 blender?

After use, fill the jar halfway with warm water and add a drop of dish soap. Run the blender on low speed for 30 seconds, then rinse thoroughly. The jar and lid are dishwasher safe (top rack only). Wipe the base with a damp cloth; do not immerse in water.

Can I blend hot liquids in the CSM-32?

No, avoid blending hot liquids above 60°C to prevent pressure buildup and potential leaks. Always let hot ingredients cool before blending, and never fill the jar more than halfway with hot contents.

How do I use the pulse function?

Press and hold the Pulse button for short bursts to control chopping or blending. Release to stop. This is ideal for coarse chopping or mixing without over-processing.

What is the maximum capacity of the blender jar?

The jar has a maximum capacity of 1.5 liters. Do not exceed the 'MAX' line to avoid spills and motor strain. For hot liquids or foamy recipes, fill only to the 1.0 L mark.

Can I replace the blade assembly?

Yes, the blade assembly is replaceable. Contact JBL customer service for genuine spare parts. To remove, unscrew the blade base from the jar. Always handle blades with care as they are sharp.

Is the blender jar dishwasher safe?

Yes, the jar, lid, and measuring cap are dishwasher safe on the top rack. The blade assembly should be rinsed immediately after use to prevent residue buildup. Do not use abrasive cleaners.

Why does my blender leak from the bottom?

Leaks usually occur if the blade base is not tightened properly or the sealing gasket is worn. Ensure the blade assembly is screwed on firmly. Check the rubber gasket for cracks and replace if needed.

How should I store the blender?

Store the blender with the jar placed upside down on the base to allow airflow and prevent odors. Keep the power cord loosely wrapped. Do not store the blender near heat sources or in damp areas.

Can the CSM-32 crush ice?

Yes, the stainless steel blades can crush ice for smoothies and frozen drinks. Use the Pulse function in short bursts for best results. Do not fill the jar more than halfway with ice.

What should I do if the blender does not start?

Ensure the jar is properly seated on the base and the lid is locked securely. The blender has a safety interlock that prevents operation if not assembled correctly. Check the power cord and outlet, and reset the circuit breaker if needed.

1.0 Introduction

1.1 JBL Commercial CSM-21 and CSM-32 Mixer

The JBL Commercial ^® CSM-21 and CSM-32 mixers (hereafter called mixer) are specifically designed for flexible routing and control of multiple audio sources. To facilitate this, JBL has equipped the mixer 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 the realm of business. The mixers have been designed to make them easier to operate than any other product in their class. In reality, the feature set provided by the mixers put them in a class by themselves.

CSM-32 mixers provide 3 channel stereo inputs and 2 zone full range stereo outputs, and are equipped with functional connectors that provide connections to your microphones, direct input (fire alarm system), auxiliary devices, and CSR remote controls. CSM-21 mixers provide 2 channel stereo input, 1 zone full range stereo output, and are equipped with functional connectors that provide connections to microphones, direct input (fire alarm system), and CSR remote controls. For details about connectors and controls of mixes, refer to later chapters in this guide.

JBL's AutoWarmth™ and LevelGuard™ controls give you excellent sounding, easy to use equalization and dynamics control. This function allows the signal to be tailored for a wide variety of rooms, taste, and volume requirements.

1.2 Other Mixer Features

The mixers also feature linking capability. This is accomplished by connecting standard category 5 UTP cables to the mixer's LINK jacks.

Linking of multiple mixers provides additional output zones yet does not increase the number of inputs. SOURCES linking simply allows multiple mixers to share the same input source, eliminating the need for Y-cables. MAIN linking allows multiple mixers to share MIC input, MUSIC MUTE, and DIRECT INPUT functions. When multiple units are linked, there is no master or slave designation. The functions are simply paralleled so that sources, MIC input, MUSIC MUTE, and DIRECT INPUT can be run into any of the linked mixers.

JBL offers several optional remote controls: CSR-V, CSR-2SV, and CSR-3SV. These remote controls provide remote source selection and/or volume adjustments within a zone location.

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 is carefully checked before packing to ensure flawless appearance and operation and that it reaches you in first class condition.

Please unpack and inspect your 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. We will be happy to help as needed. Save the shipping carton as evidence of damage for the shipper's inspection.

We also recommend that you save all packing materials so you will have them if you ever need to transport the unit. Never ship the unit without the factory pack.

2.2 Mechanical Requirements

Adequate ventilation must be provided by allowing sufficient space around the sides, top, and rear of the mixer to ensure free circulation of air. Forced cooling is not required. The mixer requires a vertical rack space of 1U. Failure to do so may damage the mixer and invalidate the warranty.

2.3 Installing the Mixer

CAUTION: Before you begin, make sure that your mixer is disconnected from the power source and all level controls are turned completely down (counter-clockwise).

To install the mixer, you can use one of the following approaches:

• Use the original brackets come with the mixer.
1. Align holes of a bracket with the holes on the case.
2. Fasten the bracket with the provided screws.
3. Follow step 1 to 2 to install rest bracket(s) to the case according your application.
4. Install the assembly into the cabinet. For details of installation in the chassis of the cabinet, refer to the user guide of your cabinet.
• Install the mixer to the wall. See the Method 2 in the above figure.
• Stack amps without using a cabinet.

NOTE: When transporting, the mixer should be supported at both front and back.

2.4 Audio Input and Output Wiring Convention

Balanced wiring - The convention for balanced wiring (2-wire plus shield) is:

Unbalanced wiring - The convention for unbalanced wiring to the inputs (1-wire plus shield) is:

NOTE: The above wiring conventions are applicable for the following connectors: MIC INPUT, DIRECT INPUT, ISO AUX OUTPUT and ZONE OUTPUT.

2.5 Using Optimal Settings When Working with CSA-2120 Amplifiers

When working with the default level settings of CSA-2120 amplifiers, to optimize the volume performance of the mixer and CSA-2120 amplifiers, you are recommended to use the following settings:

1. Set the Bass and Treble trim pots on the front panel of the mixer to the vertical positions, as shown below:

1. Set the MIC gain trim pot on the rear panel of the mixer to the optimal level as shown below:

1. Maintain a gap around 10 cm between the speaker's mouth and the microphone.

3.0 Rear Panel

1. Power Supply Input

Connect your included JBL power supply here.

2. Firmware Update

The USB connector allows you to connect your computer to the mixer and update the firmware of the mixer.

You can know the version of this firmware by observing the LEDs on the rear panel during the mixer booting process. The LED in SOURCE 1 section indicates major. The LED in SOURCE 2 section indicates minor. The LED in SOURCE 3 section indicates build. The LED beside MIC connector indicates revision. Each LED will flash in green once or more times for the numeral it stands for. The format is "major.minor[.build[.revision]]". For example, if the first released version is "v1.0.0.0", when you switch on the mixer, the LED in SOURCE 1 section will flash once, and the rest LEDs will turn red directly. Then the unit is ready for use.

3. Crossover

This switch activates the ZONE output 125 Hz crossover functionality on the left, right, and subwoofer outputs. When the crossover is “in”, the left and right outputs will allow frequencies above 125Hz to pass. The subwoofer output will allow frequencies below 125 Hz to pass. When the crossover is “out”, the left, right, and subwoofer outputs will pass full-range audio to allow the end-user to utilize the built-in crossover functionality on their speakers if desired. Use this crossover if the bass response of your room is too boomy, when you are using inexpensive loudspeaker transformers or in conjunction with the subwoofer crossover (see subwoofer crossover section).

4. Zone Output(s)

The mixer outputs utilize balanced Euroblock connectors. These outputs carry the Left, Right, and Subwoofer signals. Connect these to your zone power amplifier.

5. AutoWarmth™ Indicator and Trim Pot

These indicators flash green when the AutoWarmth function is being activated. This trim pot adjusts at what point AutoWarmth ^™ is engaged.

6. Zone Remote Jacks

These inputs are for the optional remote controls: CSR-V, CSR-2SV, and CSR-3SV.

7. Isolated Auxiliary Output*

This sends a transformer isolated mono signal for a music-on-hold system, or for a separate mono auxiliary 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. The level control adjusts the output level to match a variety of applications.

P11

NOTE : THE P11 JUMBER IS LOCATED ON THE PCB OF THE MIXER. AS SHIPPED, THE SOURCE FEEDING THE AUXILIARY OUTPUT IS SELECTED BY THE ZONE 1 SOURCE SELECTOR. WHATEVER SOURCE IS SELECTED BY ZONE 1 IS WHAT COMES OUT OF THE AUXILIARY OUTPUT. THIS CAN BE CHANGED TO ALWAYS BE SOURCE 3 BY REMOVING AN INTERNAL JUMPER CAP.

8. Page Assign

This allows you to assign pages between output zones. This can be accomplished with a simple remote selector switch or can be hard wired if pages are to the same zone every time. Shorting a zone pin (Z1 or Z2 or both) to the "G" pin assigns the page to that zone.

9. Source Inputs

Connect your RCA equipped source signals here.

10. Link Jacks

These inputs allow you to network multiple CSM mixers together. The units are connected by standard category 5 UTP cables. The length of the linking cable must be kept to under 2.4 meters.

11. Music Mute

This can be wired to a switch that mutes the background music when pin 2 is shorted to ground pin 1.

NOTE 1: MUSIC MUTE DOES NOT MUTE THE PAGING MIC AND DIRECT INPUT. IN AN EMERGENCY SITUATION, THE SYSTEM USER MAY NEED TO USE THE PAGING MIC FOR EMERGENCY ANNOUNCEMENTS.

NOTE 2: WHEN THE CSM-21 AND CSM-32 MIXERS ARE LINKED TO PROVIDE AN ADDITIONAL OUTPUT ZONE, MUSIC MUTE WILL BE APPLIED TO OTHER CSM-21 AND CSM-32 MIXERS THROUGH THE LINK CONNECTION.

12. Direct Input

The Direct Input signal is buffered and sent directly to the outputs. This is useful for alarms, emergency pages, or for another priority level of paging. The gain control adjusts the volume of Direct Input to the Zones.

NOTE : THE DIRECT INPUT REQUIRES A LINE-LEVEL SIGNAL, A MICROPHONE PRE-AMP IS NEEDED TO BOOST A MIC LEVEL SIGNAL BEFORE IT CAN BE RUN INTO THE DIRECT INPUT.

Items with * are the controls only found on the CSM-32 mixer.

13. Priority Hold

Priority Hold smoothly adjusts the time it takes for the normal input source to become audible 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. Line level paging inputs from telephone systems must be externally transformer isolated and reduced in volume to microphone level.

15. Phantom Power

This switch provides +48 V power for condenser microphones.

4.0 Front Panel

CSM-32 illustration

CSM-21 illustration

1. Source Selector

The SELECT knob selects which source is sending to that zone, or selects remote control with a remote control. To activate source selector on the remote 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. The range of this knob is: -inf, -48 to +15dB

3. Microphone Level Knob

This MIC level knob increases or decreases the level of the paging mic. The range of the knob is -inf,-30 to 0dB.

NOTE: the range of the MIC level knob is determined by the Mic Minimum setting. When the Mic Minimum trim pot is set to full clock-wise position, the range of the MIC level knob is limited to -10 to 0 dB.

4. Bass Zone EQ

The Bass trim pot cuts/boosts the zone's low frequencies.

5. Treble Zone EQ

The Treble trim pot cuts/boosts the zone's high frequencies.

6. Stereo/Mono Switch

This switch reduces the stereo image to mono. This is helpful for adjusting for mono input sources, or for stereo input sources into a mono system.

7. Bass Mic EQ

The Bass trim pot cuts/boosts by +/-6 dB the Microphone's low frequencies.

8. Treble Mic EQ

The Treble trim pot cuts/boosts by +/- 6 dB the microphone's high frequencies.

9. LevelGuard™ Threshold

This LED flashes amber when the LevelGuard ^™ function has been activated. Adjusts the threshold at which the LevelGuard ^™ function is activated. Fully clockwise is off.

10. Mic Minimum Volume Trim Pot

Sets the desired minimum paging microphone level, enabling the microphone's lowest preferred level to be set. This ensures that the main mic level control cannot be accidentally set to totally turn off a page into that zone.

11. Source Priority Switch

Selects whether Sources 2 and 3 are overridden by the Source 1 input.

12. Ducking

Ducking automatically decreases the level of the background music when a page takes place. Set the Sensitivity control so that the ducking occurs reliably whenever a mic page occurs. Set the depth control to suit the application. Typical ducking would be with the control straight up, letting through some of the background music during a page. You can set the depth for full, minimal, or no ducking of the music, as required.

13. Power Switch

Turns the mixer on/off.

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 end up. The mixer outputs a stereo or mono signal to your chosen zone. Built-in subwoofer crossovers allow you to include a subwoofer in that zone. This allows you to attain the wide bandwidth sound your patrons are used to hearing.

5.3 Volume

What is a good volume? Determining a good volume is a balance of art and science. You need maximum coverage without interfering with the workplace environment or customer comfort and communication.

The mixer gives you the tools you need in the form of AutoWarmth™ and LevelGuard™ to get the best sound quality from the volume that each application requires. Once you have set your volume preferences, AutoWarmth™ and LevelGuard™ help you keep it that way.

5.4 AutoWarmth™

What is AutoWarmth™? In its simplest terms JBL's AutoWarmth™ can be thought of as being similar to the "loudness" control on a home stereo, except its actual functions are considerably more complex. AutoWarmth™ operates on a variable basis and automatically makes the proper adjustments to maintain an even tonal perception. This function constantly adjusts for the ear's tendency to hear more low frequencies at low volumes, and less low frequencies at high volumes. AutoWarmth™ automatically ensures full music fidelity at all volumes.

5.5 LevelGuard™

What is LevelGuard™? The LevelGuard™ function helps keep the volumes of various sources consistent by sensing the level of the incoming audio source and automatically processing the signal to a user selected preference.

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. Background music (SOURCE 2 and SOURCE 3)

In this example, your alarms would connect to the Direct Input, your page microphone connects to the MIC Input, prerecorded announcements connect to SOURCE 1, and background music connects to SOURCE 2 and 3.

NOTE: MUSIC MUTE DOES NOT MUTE THE PAGING MIC. IN AN EMERGENCY SITUATION IT IS USU-ALLY BEST TO KEEP ALL MICROPHONES ACTIVE FOR ANNOUNCEMENTS.

6.2 Connecting Sources

Connecting your sources is also very simple. Just connect the left and right outputs of your source to the left and right input of the mixer.

6.3 Adjusting Source Gain

Check the input level LEDs, they should show green for continuous signal. Red will flash if the input is too strong. Occasional flashes into the red are not harmful if no distortion is apparent.

6.4 Using EQ

The best determination for needed equalization is to trust your ears. Does the output sound boomy. Reduce bass setting or engage the high pass filter, this will reduce the bass frequencies. Does it sound dark or muffled? Turn up the treble. Or if it sounds thin or harsh, decrease the treble. Just like the tone controls on a car or home stereo.

6.5 Using 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 with a slope of 24 dB per octave), forming a full subwoofer crossover. When the XOVR switch is NOT engaged, the main speaker outputs and the subwoofer outputs are full-range.

6.6 Setting Up AutoWarmth™ Method 1

To set up AutoWarmth™ begin by turning the AutoWarmth™ trimmer to the twelve o'clock position. Use this as your "baseline" setting. Now turn up the source volume (on front panel) to a typical operating level for that zone. Check the AutoWarmth™ indicator LED, on quieter passages the indicator should flash green. If it does not, start turning the trim pot clockwise until it does. If the indicator is constantly on, turn the trim pot counter-clockwise until it flashes only occasionally.

Then adjust the bass and treble tone controls for that zone. To check the adjustments, turn the volume down to as low as its ever going to be used in that zone and make sure the tone sounds full enough. If not then turn the AutoWarmth™ trimmer further clockwise to increase its effect. Go back and forth between typical level, low level, and high level. Adjust AutoWarmth™ for the best overall sound at all the compared levels.

6.7 Setting Up AutoWarmth™ Method 2

An alternate method is to turn the AutoWarmth™ trimmer full counter-clockwise. Turn the Source volume (on front panel) to the highest volume at which that zone will be operated. Adjust the AutoWarmth™ trimmer clockwise until the green LED just starts to light on musical peaks. Then turn the AutoWarmth™ trimmer back counter-clockwise until it does not light at all. Next turn the zone's level down to normal operating level and adjust the bass and treble controls for that zone, the AutoWarmth LED will light.

With either of these setup methods, AutoWarmth™ should shut off when operating at higher volumes and be lit at both normal and lower volumes.

6.8 Setting Up LevelGuard™

To set up LevelGuard™ begin by turning the LevelGuard™ trim pot to 12:00. 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. It is useful to set LevelGuard™ so that the LED stays unlit during very low volume music, flashes on and off during normal volume, and then lights continuously as the volume increases. Adjust by ear to sound best.

6.9 Security Cover

Affix the security panel over the front panel setup controls to prevent tampering.

Appendix A. Optional Item - CSR Series Remote Controls

CSR-V

CSR-2SV

CSR-3SV
Optional remote controls are available from JBL to provide source selection and volume control from a remote location other than your mixer.

Selecting Source

The Source Selection control on the remote control only functions when the Source Selector switch for that zone is set to "REMOTE" on the mixer. When the remote control is active, the green LED on the remote control below the Source switch (labelled ACTIVE) lights. When this LED is not lit, the remote source control is not operational.

Controlling Volume

The LEVEL on the mixer is ALWAYS operational, regardless whether the Source Selector is active or not. This remote control is ATTENUATE ONLY.

To set the volume control of the remote control, you can follow the steps:

1. Turn the remote control LEVEL to maximum (full clockwise).

Appendix B: Applications

Retail

This is for facility comprised of one zone, for example, the retail consisting of the shopping area and change rooms. The remote controls allow you to select source and control volume from a remote location. The CSM's LevelGuard™ features keeps the volume range at optimum and AutoWarmth™ automatically adjusts to ensure full high-fidelity sound regardless of the volume. The store audio system has background music and paging capability.

Restaurant

This is for facility comprised of two zones, for example, dining area and kitchen. Each zone is with independent volume capability and source selection via remote controls located within that zone. The CSM's LevelGuard™ features keeps the volume range at optimum and AutoWarmth™ automatically adjusts to ensure full high-fidelity sound regardless of the volume.

Fitness Center

This is for a facility comprised of four zones, each with independent volume capability and source selection via remote controls located within that zone. The reception area comprises one zone. The central hall, cardiovascular training area, aerobic training and strength training areas constitute another zone. The pool is one zone, and the cycling room, dancing room, yoga room, and locker rooms are as the fourth zone. The selection of loudspeakers for the facility depends on which form factor the architecture requires, how the floor plan is laid out for coverage, and the sound level requirements. For high SPL facilities, the amplification system is expandable. For wide bandwidth fitness centers, a subwoofer can be easily added. The CSM's LevelGuard™ feature keeps the volume range at optimum and Auto-Warmth™ automatically adjusts to ensure full high-fidelity sound regardless of the volume.
