The Q Series consists of three models: Q130 is a high quality, constant Q, 1/3 octave, Graphic Equalizer; The Q215 is a high quality constant Q, 2/3 Octave Equalizer and the Q230, dual channel, constant Q, 1/3 Octave Equalizer. They are designed to provide transparent and accurate frequency shaping capability in an easy to use package. The separate frequency bands, ranging from 25 Hz to 20kHz allow you to “tune” the sound system to the room to create the best sounding system. Using long throw faders makes fine adjustments of each band easy and accurate. Other features include a by-pass switch to allow you to compare the equalized sound from the unfiltered sound, thereby allowing you to fine tune the system. The Q Series uses balanced and unbalanced Input/Output connectors to allow you to use it in a variety of applications. The rack-mountable chassis allows you to quickly install the units into an equipment rack or your audio cabinet. 3 Q Series INTRODUCTION Wharfedale Q Series Equalizers are the result of many years of experience in the use, design and manufacturing of professional sound reinforcement products. We take great pride in engineering and building every Wharfedale Pro product and wish to thank you for entrusting us with your sound. From the time Gilbert Briggs built his first loudspeaker in 1932, to the present, Wharfedale Professional products have maintained the same standard of quality in components, workmanship and performance. Please take a few minutes to read this manual completely in order to ensure that you get the most out of your equalizers. Q SERIES EQUALIZER OVERVIEW: The Q Series Equalizers are accurate, high quality, Constant Q graphic equalizers. This allows you to tailor your sound to make it sound the best in a room or tailor the sound of your music. With low distortion and flexible features, these equalizers are the right tools to bring to the show. The Q Series has many user-friendly features. These easy to adjust and use features include, long travel slide faders (Q-130), by-pass switch, soft limit switch, variable high pass filter control and easy to read LED meters. 4 OPERATING MANUAL AND USER GUIDE FEATURES ♦ Three models o Q-230: Two Channel 30 band, 1/3 Octave Equalizer o Q-130: Single Channel 30 band, 1/3 Octave Equalizer o Q-215: Two Channel 15 band, 2/3 Octave Equalizer 5 ♦ Constant Q ♦ By-pass switch ♦ Soft Limit Switch ♦ Variable High pass filter 10Hz – 200Hz (Q-130) ♦ Variable High pass filter 10Hz – 100Hz (Q-230) ♦ Easy to read LED meters ♦ Professional long throw slide faders (Q-130) ♦ XLR/ 1/4” TRS balanced/unbalanced inputs/outputs ♦ Output Ground lift switch Q Series BLOCK DIAGRAM TYPICAL WIRING DIAGRAM FOR THE Q130 CROSSOVER IN SYSTEM SETUP SIGNAL INPUT MIC, CD etc. TO MIXER MIXER OUTPUT OUTPUTS FROM GRAPHIC EQUALISER TO CROSSOVER INPUT TO GRAPHIC EQUALISER SEPARATE HIGH/MID AND LOW OUTPUTS TO AMPLIFIER(S) FROM CROSSOVER INPUTS TO CROSSOVER SEPARATE HIGH/MID SPEAKER OUTPUT TO HIGH/MID SPEAKER FROM AMPLIFIER INPUTS TO AMPLIFIER(S) SEPARATE LOW SPEAKER OUTPUT TO LOW FREQUENCY SPEAKER FROM AMPLIFIER = SIGNAL (SHIELDED) CABLE = LOUDSPEAKER (NON-SHIELDED) CABLE 6 OPERATING MANUAL AND USER GUIDE SETTING UP The Q Series Equalizers are easy to install and operate. Before plugging in the Q Series Equalizers, or any electrical audio device, be sure that the power switch is in the off position, the volume control is all the way down (at 0 level) and all audio connections are made. After power-up, speak into your mic start the CD or MP3 player or other line level device and slowly increase the volume to the desired level. Avoid distortion (or overdriving the input) as it can damage your system in the long term. If you cannot achieve the desired sound level in your system, you must add more speakers or a subwoofer to the system. CONNECTIONS / WIRING Connecting Q Series Equalizers to your system is straightforward. You simply plug in your cables (microphone or line level) from the output of the mixer to the input of the EQ; then from the EQ output to an amplifier. Always use good quality microphone (2 conductor + shield) cable. After you plug in the components, you must adjust the sound level to produce the best sound. A good place to start is the mixer then EQ then amplifier. 7 Q Series Gain Stage Adjustments: • Plug the mic in and position the volume control at ´0´ (zero) dB. Keep the main output volume down as well as the other components volume controls. • Whilst watching the meters, speak or sing (it’s always good to warm up your voice) into the mic in the same way as your performance and adjust the GAIN control, usually at the top of the mixer channel near the mic input jack, to the point where the meters spend a lot of time at or near the ´0dB´ (zero). An occasional red peak light is OK, just make sure the meters are not in the red area very long. • Next adjust the main output so that the meters are at the ´0´ (zero) position most of the time, or at the loudest part of your performance. This takes time and practice to get the best sound. • The next stop is the EQ. The idea of all these adjustments is be sure you get the best and cleanest signal going down the line. Start with the gain or volume control in the 0 position. • The next step: Tuning the room (a/k/a ringing out the system). See page 9,10. • In a simple system, the next component is the amplifier. Because your previous adjustments have resulted in the cleanest, loudest sound coming from the mixer to the EQ, it is not uncommon for the volume controls on the amplifier to be less than maximum (a/k/a “11”). Don ’ t worry, this means you have plenty of room to get louder. If your amplifier volume control is “max ’ d out” when you are at this point in the setup, you have no place to go. You must add to your system; either more amps or more speakers. • The bottom line is to keep watch over your meters, they will tell you if the sound levels throughout the system are in keeping with good practices. 8 OPERATING MANUAL AND USER GUIDE Tuning the Room: A graphic equalizer is a very valuable tool for the traveling musician. It allows you to get the best sound in a variety of venues. As we know, all rooms are not created equal. They have their own personality. That is to say, your sound system will not sound the same from room to room. Using the EQ correctly will help you maintain “your sound”. • The controls on the Equalizer provide level adjustment to frequencies in the audio spectrum. You adjust them either louder (up) or quieter (down) to make the overall sound in the room better. • To tune the system to the room, it takes some practice and patience. You play PINK NOISE through the system and adjust each frequency so that the response is the same for every frequency. You can download pink noise and save it to CD or MP3/4 player. • To effectively measure and adjust the system response, you will need a Real Time Analyzer (RTA). This device displays the system frequency response. They are available in rack mounted, hand held and software formats. • When your ear gets calibrated, you can tune the system by ear. • Using pink noise through the system and an RTA, adjust the frequency response of the system to look flat. Minor adjustments by ear can be made later, but only minor adjustments. • Leave the EQ alone until the next gig or the room changes significantly. However, if it changes too much, it is too late to run the above procedure and you must “do it by ear” • Use the individual channel EQ on the mixer to get the music and vocals to mix properly. 9 Q Series Q Series with connections shown 10 OPERATING MANUAL AND USER GUIDE SPECIFICATIONS Q-130 Q-215 Q-230 1/4" TRS, female XLR 1/4" TRS, female XLR 1/4" TRS, female XLR (pin 2 hot) (pin 2 hot) (pin 2 hot) Electronically balanced/ Electronically balanced/ Electronically balanced/ unbalanced, RF filtered unbalanced, RF filtered unbalanced, RF filtered Balanced 20k ohm, unbalanced Balanced 20k ohm, unbalanced Balanced 20k ohm, unbalanced 10k ohm 10k ohm 10k ohm Max Input Level: >+21dBu balanced or unbalanced >+21dBu balanced or unbalanced >+21dBu balanced or unbalanced CMRR: >40dB, typically >55dB at 1kHz >40dB, typically >55dB at 1kHz >40dB, typically >55dB at 1kHz Type: Impedance-balanced/ Impedance-balanced/ Impedance-balanced/ unbalanced, RF filtered unbalanced, RF filtered unbalanced, RF filtered INPUT/ OUTPUT Connectors: Type: Input Impedance: Output Impedance: Balanced 100 ohm, unbalanced 50 Balanced 100 ohm, unbalanced 50 Balanced 100 ohm, unbalanced 50 ohm ohm ohm >+21dBu balanced/ unbalanced >+21dBu balanced/ unbalanced >+21dBu balanced/ unbalanced into 2k ohm or greater into 2k ohm or greater into 2k ohm or greater Bandwidth: 20Hz to 20kHz, +0.5/-1dB 20Hz to 20kHz, +0.5/-1dB 20Hz to 20kHz, +0.5/-1dB Frequency Response: <10Hz to >50kHz, +0.5/-3dB <10Hz to >50kHz, +0.5/-3dB <10Hz to >50kHz, +0.5/-3dB Dynamic Range: 108 dB 108 dB 108 dB Signal-to-Noise: 90 dB 90 dB 90 dB THD + Noise: <0.004% <0.004% <0.004% Interchannel Crosstalk: <-80dB, 20Hz to 20kHz <-80dB, 20Hz to 20kHz <-80dB, 20Hz to 20kHz Bypasses the graphic equalizer Bypasses the graphic equalizer Bypasses the graphic equalizer section in the signal path section in the signal path section in the signal path Activates the 50Hz 12dB/ Activates the 50Hz 12dB/ Activates the 50Hz 12dB/ octave high-pass filter octave high-pass filter octave high-pass filter Selects either +/- 6dB or Selects either +/- 6dB or Selects either +/- 6dB or +/-12dB slider boost/cut range +/-12dB slider boost/cut range +/-12dB slider boost/cut range 100VAC 50/60Hz, 120VAC 100VAC 50/60Hz, 120VAC 100VAC 50/60Hz, 120VAC 60Hz, 230VAC 50/60Hz 60Hz, 230VAC 50/60Hz 60Hz, 230VAC 50/60Hz Power consumption: 12W 12W 12W Mains Connection: IEC receptacle IEC receptacle IEC receptacle Dimension: 482.6 x 170 x 88 mm 482.6 x 168 x 44mm 482.6 x 168 x 88 mm Weight 4.0 kg 2.96 kg 3.93 kg Max Output Level: SYSTEM PERFORMANCE FUNCTION SWITCHES EQ Bypass: Low Cut: Range: POWER SUPPLY Operating Voltage: DIMENSIONS/WEIGHT 11 Q Series Dimensional 88.00 Q130 88.00 482.60 435.00 44.00 Q215 482.60 88.00 Q230 435.00 88.00 482.60 434.00 WHARFEDALE PRO LIMITED WARRANTY Wharfedale Pro products are warranted of manufacturing or material defects for a period of one year from the original date of purchase.
