How to Use This Manual:

After this introduction, a getting started guide will help you get things set up fast. The hookup diagrams show some typical setups, while the remaining sections provide details of the CR3-XBT, CR4-XBT, CR5-XBT and CR8-XBT monitors.

This icon marks information that is critically important or unique to these monitors. For your own good (and our peace of mind), please read and remember them. You will be quizzed later.

Getting Started

We realize that you can’t wait to hook up your CR-XBT Multimedia Monitors and try them out. Nevertheless, please take the time to read this page NOW, and the rest can wait until you’re good and ready.

1. Turn the volume control on the front of the powered CR-XBT monitor down (fully counterclockwise) before turning the unit on for the first time.

2. Set the power switch on the back panel off. This will prevent you from accidentally connecting a hot signal source to the monitor and getting a rude surprise.

3. Connect the black (–) and red (+) speaker wires from the powered monitor’s ± spring clips to the passive monitor’s ± spring clips.

4. Connect the affixed line cord into an AC outlet. The monitor may accept the appropriate voltage as indicated on the back panel.

5. Turn on the power switch on the rear panel of the CR-XBT monitor.

6. Connect your device via Bluetooth [instructions on pages 8-9]...


Connect the line-level monitor signal from your computer, mixer, or other signal source to the input jacks on the rear panel of the monitor (1/4", RCA or 1/8").

7. Turn the front panel volume control clockwise until the monitor “clicks” on and the ring surrounding the volume knob illuminates.

8. Play an audio file and slowly turn the front panel volume control to a comfortable listening level.

If you desire a more thorough walk-through of your CR-XBT monitors, there is a wealth of information in the following pages!

Please write the serial numbers here for future reference (i.e., insurance claims, tech support, return authorization, make dad proud, etc.) Purchased at: Date of purchase: Additional Tidbits of Wisdom

• Never listen to loud music for prolonged periods. Please see the Safety Instructions on page 2 for information on hearing protection.

• When you shut down your equipment, turn off the monitors first to prevent thumps and other noises generated by any upstream equipment from coming out the speakers. When powering up, turn on the monitors last.

• Save the sales receipt and original packaging in case you ever need warranty service. See page 16 for details.

Hookup Diagrams

CR3-XBT / CR4-XBT / CR5-XBT / CR8-XBT CR3-XBT / CR4-XBT / CR5-XBT / CR8-XBT The illustration above shows a typical use for CR-XBT Series Multimedia Monitors. Everyone needs tunes while working, right... or is it just me?

In this example, simply connect the (included) cable from the computer’s 1/8" output jack to the L/R RCA inputs of the powered CR-XBT Series Multimedia Monitor. If you prefer to use 1/4" inputs instead of RCA inputs, that option is available, too. As seen above, the CR5-XBT and CR8-XBT also have an 1/8" input jack if that’s more your jam.

Next we’ll want to connect the passive speaker. The included black (–) and red (+) speaker wires should be connected from the powered monitor’s ± spring clips to the passive monitor’s ± spring clips as detailed by the dotted lines above: Connect black (–) to black (–) and red (+) to red (+).

Almost there! Move the ‘Powered Speaker Position Select’ switch to either the “L” or “R” position based on whether the powered reference monitor – the one with the volume knob – will be on the left or right side.

Now position the monitors where you would like them. Play audio through the computer, making sure that the volume of the computer and monitors are above “0”.

Last step: move the monitors around until the optimal sound has been achieved and adjust volume to taste.

Optional (CR5-XBT and CR8-XBT): place the included acoustic isolation pads underneath the monitors to minimize boomy bass build-up and provide up/down tilt control for more focused listening.

Hookup Diagrams continued...

CR3-XBT / CR4-XBT / CR5-XBT / CR8-XBT CR3-XBT / CR4-XBT / CR5-XBT / CR8-XBT The illustration above shows a common use for CR-XBT Series Multimedia Monitors. Perhaps a friend created a playlist on their smartphone and wants to share it. With great hesitation, you finally oblige. Everyone has that one friend with terrible taste in music. We know, it happens.

In this example, a smartphone is connected to the CR-XBT Series Multimedia Monitors via Bluetooth.

Next we’ll want to connect the passive speaker. The included black (–) and red (+) speaker wires should be connected from the powered monitor’s ± spring clips to the passive monitor’s ± spring clips as detailed by the dotted lines above: Connect black (–) to black (–) and red (+) to red (+).

Almost there! Move the ‘Powered Speaker Position Select’ switch to either the “L” or “R” position based on whether the powered reference monitor – the one with the volume knob – will be on the left or right side.

Now position the monitors where you would like them. Play audio through the smartphone making sure that the volume of the smartphone and monitors are above “0”.

Last step: move the monitors around until the optimal sound has been achieved and adjust volume to taste.

Optional: plugging a pair of headphones into the 1/8" headphones jack auto-defeats the speaker output. The front panel volume control then controls the level going to the phones.

3. Signal Inputs

Connect the line-level signal from a computer, mixer, or other signal source to one pair of these input jacks. There are two types of input connectors to choose from: 1/4" line-level signals driven by balanced or unbalanced sources or RCA line-level signals driven by unbalanced sources. Since these are connected together electrically, do not connect more than one signal at a time to the input jacks.

A balanced signal provides better noise rejection and is the preferred method, especially if using a cable longer than 20 feet (6 meters).

They are wired as follows, according to standards specified by the AES (Audio Engineering Society): 1/4" TRS Balanced Mono Wiring: Sleeve = Shield (Ground) Tip = Hot (+) Ring = Cold (–) RING SLEEVE SLEEVE RING TIP TIP RING TIP SLEEVE 2 1 To connect unbalanced lines to these inputs, use a 1/4" mono (TS) phone plug, wired as follows: 1/4" TS Unbalanced Mono Wiring: Sleeve = Shield (Ground) Tip = Hot (+) SLEEVE SLEEVE TIP TIP TIP SLEEVE

1. AC Line Cord

Plug the attached power cord into a live AC outlet that has the correct voltage indicated on the rear panel.

2. Power Switch

Press this switch left to turn the CR-XBT multimedia monitors on. Make sure the volume knob is off [fully counter-clockwise] before turning it on. The ring surrounding the Running Man logo on the front panel illuminates white when the CR-XBT multimedia monitor is plugged into an AC outlet, the power switch is turned on and the front panel volume control is turned clockwise until the monitor “clicks” on.

Press the right side of this switch down to turn the CR-XBT multimedia monitors off.

The unbalanced RCA plugs are wired as follows: Unbalanced RCA Sleeve = Shield (Ground) Tip = Hot (+) SLEEVE TIP SLEEVE TIP

4. 1/8" Stereo Input [CR5-XBT and CR8-XBT]

Connect a line-level signal from an MP3 player, phone or other signal source to this input jack using an unbalanced 1/8" connector.

It is wired as follows, according to standards specified by the AES (Audio Engineering Society): Stereo 1/8" TRS Sleeve = Shield (Ground) Tip = Left Channel Ring = Right Channel Owner’s Manual 7

5. Powered Speaker Position Select Switch

Here you get to decide if the powered monitor is to be positioned on the left side (switch up) or right side (switch down) of the desk. One convenience is that it keeps the power cord, front and/or rear panel connections from crossing your work space. Additionally, it doesn’t discriminate between right or left-handed users. Simply set it up to suit your preference.

6. Wire Terminals (±)

Connect the included black (–) and red (+) speaker wires from the powered monitor’s ± spring clips [big green ball number 6 on the previous page] to the passive monitor’s ± spring clips (as seen to the right).


CR-XBT: Front Panel Features

8. Phones Output

This 1/8" TRS connector supplies the output to stereo headphones. The volume is controlled with the volume knob. The signal to the power amp is killed when headphones are connected.

The phones output is wired as follows, according to standards specified by the AES (Audio Engineering Society): Stereo 1/8" TRS Sleeve = Shield (Ground) Tip = Left Channel Ring = Right Channel Warning: listen carefully.

The headphone amp is loud and could cause permanent hearing damage. Even intermediate levels may be painfully loud with some headphones. BE CAREFUL! Always turn the volume knob all the way down before connecting headphones. Then turn it up slowly as you

7. Custom-Tuned Rear Port

The custom-tuned rear port uses the radiation from the rear of the woofer cone to extend the low-frequency response of the speaker. The size of the port is carefully designed with respect to the volume of the cabinet and the characteristics of the woofer to produce low-frequency extension.





9. Volume Knob

CR-XBT Series multimedia monitors expect a line-level signal at its input. Use this control to adjust the sensitivity of the input section according to the signal strength at its input.

The volume knob not only adjusts the overall output level, but it also turns the monitor on and off. Simply turn the knob counter-clockwise until it “clicks” off. Turn the knob clockwise to turn the volume up.

Refer to the Quick Start section on page 4 for the level-setting procedure.

10. Running Man Bluetooth Button / LED

The ring surrounding the Running Man logo on the front panel illuminates white when the CR-XBT multimedia monitor is plugged into an AC outlet, the power switch is turned on and the front panel volume control is turned clockwise until the monitor “clicks” on.

The logo isn’t just for pretty looks and LED illumination... it’s also how to connect your device to the monitor via Bluetooth! Read on...

Upon powering up the CR-XBT, the Bluetooth function is either: (1) In sleep mode. See ‘Pairing and connecting for the first time’ (next page) or...

(2) ...Paired and connected. See ‘Previously paired and connected devices’ (next page).

8 CR-XBT Multimedia Monitors

Pairing and connecting for the first time: To enter pairing mode, press and release the Running Man logo – it doubles as the Bluetooth button! The ring surrounding the button will illuminate and flash green for approximately 30 seconds while in pairing mode. [The LED will continue to flash until it has successfully paired and connected].

While CR-XBT is in pairing mode, simultaneously scan for Bluetooth devices on your smartphone. You should see CR-XBT appear in the list of “avail able devices”. Select it by tapping it. From there, your Bluetooth device should indicate that it is successfully connected. Additionally, the Bluetooth button will stop flashing and remain solid white. If it does not, start the pairing process again, and make sure that CR-XBT and your device are both in pairing mode at the same time.

Even though these cables are included, they might need to be replaced at some point [e.g. cats play tug-of-war, you ran out of ribbon to tie a gift and used these instead]. Or perhaps you prefer to use the 1/4" inputs. If so, we recommend using high-quality, shielded cables to connect the signal source to the sig nal input jacks on CR-XBT Series multimedia monitors. Three types of input connectors are provided to interface with virtually any application you may have: • Balanced TRS / Unbalanced TS cables work well with the 1/4" inputs.

• Unbalanced phono cables work well with the RCA inputs.

• Unbalanced TRS cables work well with the 1/8" input. [CR5-XBT and CR8-XBT] Previously paired and connected devices: The Bluetooth connection will disconnect if it’s out of range. Previously paired and connected devices will automatically reconnect and the Running Man logo / Bluetooth button will illuminate (if the volume knob is at least clicked on).

While your Bluetooth device is connected to a CR-XBT, you can quickly press the Bluetooth button on the front of the unit to pause/play your audio (the same as if you’d pressed pause/play on your device).

The Bluetooth may disconnect when affected by Electrostatic Discharge [ESD]. Manually reconnect the Bluetooth connection.

11. Season Knob

Have you ever wished that you could play the role of Mother Nature and change the season? Perhaps not, but we’re located in the cold, grey, dark Pacific Northwest and could use extra vitamin D in our systems!

Rotate this knob to the season you desire. You will feel the knob “click” into place. Note that while there are four seasons listed, the in-between settings also work. For example, the last days of Winter heading into Spring are quite delightful ‘round these parts. Play with the settings and let us know what you like!

NOTE: Route the cable away from AC power cords and outlets. These are common sources for hum in an audio signal. Wall warts and line lumps are especially insidious hum inducers!

NOTE: In certain home theater applications, it may be necessary to connect the speaker outputs from a stereo receiver to the inputs of the CR-XBT Series multimedia monitors if the receiver doesn’t have preamp outputs or other line-level output connections.

CAUTION: Do not attempt to connect a speaker output directly to the input of the CR-XBT Series multimedia monitor! Speaker levels are much higher than line levels and can damage the input circuitry in the CR-XBT Series multimedia monitors.

However, it is possible to insert a speaker-level to line-level signal attenuator between the receiver’s speaker output and the CR-XBT Series multimedia monitor’s input. Any local authorized dealer should be able to assist, or you can build your own.

Input Signal Wiring

Included with the CR-XBT Series Multimedia Monitors are multiple accessories, including: • 1/8" to stereo RCA cable to connect computer output to speakers • Speaker-to-speaker cable • 1/8" to 1/8" cable to connect a smartphone or media player [CR5-XBT and CR8-XBT]

Care and Cleaning

CR-XBT Series multimedia monitors will provide many years of reliable service if you follow these guidelines.

• Avoid exposing the monitors to moisture.

• Avoid exposure to extreme cold (below freezing temperatures).

• Use a dry cloth to clean the cabinets. Only do this when the power is turned off.

Appendix A: Service Information

If you think your CR-XBT Multimedia Monitors have a problem, please check out the following troubleshooting tips and do your best to confirm the problem. Visit the Support section of our website ( where you will find lots of useful information such as FAQs and other documentation. You may find the answer to the problem without having to part with your monitors.

Poor sound

• Is it loud and distorted? Make sure that you’re not overdriving a stage in the signal chain. Verify that all level controls are set properly.

• Are the input connectors plugged completely into the jacks? Be sure all connections are secure.


• If possible, listen to the signal source with headphones plugged into the preamp stage. If it sounds bad there, it’s not the monitor.

No power

• Make sure the power cord is plugged all the way into the AC outlet.

• Our favorite question: Is it plugged in? Make sure the AC outlet is live [check with a tester or lamp].

• Too much bass or not enough bass? Move around the room and see if the bass response changes. It’s possible your listening position coincides with a room mode where the low frequencies either become exaggerated or nulled. If so, try moving the monitors to a different position, or moving your listening position.

• Our next favorite question: Is the power switch on? If not, try turning it on.

• Is the front panel volume control “clicked” on? The power is on only when the rear panel power switch is on and the front panel volume control is not fully counter-clockwise.

Noise / Hum / Buzz

• Check the signal cable between the computer/mixer/ MP3 player/phone and the reference monitor. Make sure all connections are secure. These problems usually produce crackling noises, hum, or buzz.

• Is the power LED on the front panel illuminated? If not, make sure the AC outlet is live. If so, refer to “No sound” below.

• The internal AC line fuse may be blown. This is not a user serviceable part. If you suspect the AC line fuse is blown, please see the "Repair" section next.

No sound

• Is the level knob for the input source turned all the way down? Verify that all the volume controls in the system are properly adjusted.

• If connecting an unbalanced output to the CR-XBT Series reference monitor’s balanced input, make sure the shield is connected to the unbalanced ground of the source.

• Make sure the signal cable is not routed near AC cables, power transformers, or other EMI sources (including wall warts and line lumps!). These sources usually produce hum.

• Is there a light dimmer or other triac-based device on the same AC circuit as the monitor? Dimmers cause buzzing noises. Use an AC line filter or plug the monitor into a different AC circuit.

• Is the signal source turned up? Make sure the signal level from the computer, mixer, MP3 player, phone (or whatever device immediately precedes the multimedia monitors) is high enough to produce sound.

• Excessive hiss is an indication of an incorrect gain setting somewhere before the speaker.

• If possible, listen to the signal source with headphones plugged in. If it sounds noisy there, it’s not the monitor.

• If it’s a stereo pair, try switching them around. For example, if a left output is presumed dead, switch the left and right cords at the monitor end. If the problem switches sides, it’s not the monitor. It could be a bad cable, or no signal from the source.

10 CR-XBT Multimedia Monitors

• Try disconnecting the cable connected to the input jack. If the noise disappears, it could be a “ground loop,” rather than a problem with the CR-XBT Multimedia Monitor. Try some of the following troubleshooting ideas: • Use balanced connections throughout your system for the best noise rejection.

• Whenever possible, plug all the audio a common ground. The distance between the outlets and the common ground should be as short as possible.
