There are three tools available for matching the BPM of two CDs:

− Use the pitch slider to adjust the BPM.

− Use the PITCH BEND +/- buttons to change the BPM temporarily.

− Turn the JOG dial to change the BPM temporarily.

a. Pitch Slider

1. To adjust the BPM by sliding the pitch slider up or down, press the PITCH button to turn on the PITCH adjustment function before using.

2. Slide the pitch slider up to decrease the BPM, or down to increase the BPM. The adjustme nt range is +/-8, +/-12, +/-16%.

b. Pitch Bending +/- buttons

 The BPM increases or decreases respectively when the PITCH BEND+ or PITCH BEND-

button is pressed.

 The BPM increase depends on how long you hold the button. If you hold the button for about

1/2 second, the BPM will either increase by 16% for PITCH BEND+ or decrease by 16% for PITCH BEND-. If you tap the button quickly, the BPM will only change a little so you can change the beat slightly without audible changes in the music.

 The CD will return to the tempo indicated by the Pitch slider when you let go of the PITCH

BEND+/ – button.

 Figure 11 shows an example of how to use the pitch bend function. In this example, both

players are playing and the BPM of the two CDs does not match. Use the PITCH BEND +/buttons to adjust the BPM.

c. JOG dial

Turn the jog dial clockwise during play to increase the number of BMP, and turn it counter clockwise to reduce the number of BMP. The faster you turn the wheel, the more the BMP changes. The BMP changes with a range of +/-8, +/-12, +/-16% When you release jog wheel, the CD will return to the tempo indicated by the pitch slider.

OPERATION

When switching the system on or off, we advise you to switch on the amplifier last and switch it off first so as to prevent any impact caused by the ON/OFF switch. Check whether the local power voltage the same as the one indicated on the back panel and that all the connections are correct before turning the power on.

Turn the volume adjustment dials for the left and right channels anti-clockwise to the (- ) position. Before pressing the power supply switch, please switch on the input ∝ signal source. After about 3 seconds, when you hear the relay, turn the volume adjustment dial for the left and right channels clockwise to the appropriate volume level. We suggest that you adjust the dial to the maximum (0) position and that you use the external appliance to adjust the volume level.

When using the amplifier, if the overload pilot lamp (OVERLOAD) blinks, this means the equipment is working properly and is safe to use. If the overload pilot lamp (OVERLOAD) no longer blinks, this means the equipment is overloaded. In this case, please turn down the volume until the indicator blinks again. Please carry follow this recommendation in order to avoid damaging the equipment by subjecting it to overload for too long.

About 3 seconds after switching on the equipment, you will hear a muffled sound. If you hear the same sound when using the amplifier, please switch it off then switch it back on again after checking the connections.

Connecting The Speaker System

Choosing the correct cables

The speaker connections must be made using the 6.35 mm MIC connectors on the back panel. You can use a variety of standard speaker cables that are available at your local professional audio retailer or musical instrument retailer. Ensure that standard, stranded speaker wire cables are used. A diameter between 1.63 and 2.03 mm is recommended. If you are making your own cables, use the diagrams below to ensure proper connections. If your amplifier uses binding posts you can use speaker cables with banana plugs, but be sure to pay attention to the phase otherwise you will not have the proper low-end response and stereo image.

In order to ensure that your system is in phase, be careful to pay close attention to the positive and negative markings on the amplifier and wires. Make sure that the + terminal of the speaker or connector is connected to the + terminal of the power amplifier and that the - terminal of the speaker or connector is connected to the terminal of the power amplifier.

About Impedance Before you connect your speaker, be sure that you understand a little about impedance. Impedance is the electronic load that the speaker places on the power amplifier. It is measured in Ohms.

IMPORTANT NOTE: There is minimum safe impedance for running power amplifiers so be sure to check the manufacturer's recommended impedance for your amplifier to avoid damaging your amplifier or vo iding your warranty.

Page 42

Choosing an amplifier to connect to the DJX 480 PK

The speaker has a specific power rating, which you can find out by checking the label at the back of the speaker. Refer to the Technical specifications section of this manual, to check that your power amplifier has the correct power output for this speaker. Be careful to consider the total impedance if you are connecting more than one speaker to one side of a stereo power amplifier. Using a power amplifier with a power rating that is too low can be dangerous since the output signal is often clipped in order to obtain the desired level. If the power is too high, this will result in catastrophic failure: the use of any amplifier with a power rating over the recommended power rating may damage your speakers.

Quick Set-Up

Follow the diagram and steps below to set up a basic stereo PA system quickly.

NOTE: Before plugging in and turning on the app liances, it is important to remember the rule: “LAST ON, FIRST OFF”. In other words, this means that when turning on your system, you should always turn your power amplifiers or powered monitors on LAST, and when turning your system off, turn your power amplifiers off FIRST. This helps avoid any loud noises caused by an inrush of current when the unit is switched on, as this can sometimes damage loudspeakers.

1. Before making the connections, make sure that all your system components are

turned off. Also, make sure that your power amplifier volume controls and the main left and right faders of your mixer are turned all the way down.

2. Connect the cables to your microphones and instruments, or a CD player, to your

mixer.

3. Switch on the mixer, instruments and/or CD p layer, an d then sw itch on your pow er

amplifier.

4. While speaking into the microphone (or playing an instrument or CD on a CD

player), place the main left and right faders on the mixer to the “0” position. Ensure that the signal is not clipping. If it is, turn the mixer volume down un til the signal cleans up.

5. Now, slowly increase the level on your power amp until you reach the desired

listening level.

Microphone Positioning-How to Reduce Feedback

Feedback is the annoying howling and squealing that is heard when the microphone is too close to the speaker and the volume is high. You get feedback when the microphone picks up the amplified signal from the speaker, and then amplifies through the speaker again, and then picks it up again, and so on and so on. In general, it is always recommended that any LIVE microphone (a microphone that is switched on) is positioned behind the speakers. This will allow you to obtain a better level from your system and will avoid feedback. One possible exception is when you are adjusting the sound of the microphones, since you want to be in front of the speaker to hear properly. To do this, lower the main volume while setting the EQ and effects from in front of the speakers. Once you have the sound you like, move the microphones behind the speakers and raise the main volume.

Speaker placement Whenever possible, it is a good idea to raise the speakers above the heads of the listening audience. Some speakers have a standard 1.39" (35 mm) pole mount receptacle, which is compatible with speaker stands from a variety of manufacturers.
