2、o.1 for TFX4 Time Effects OWNERS MANUAL RadioFans.CN 收音机爱 好者资料库 Thank you for purchasing the TFX4 TIME EFFECTS. By doing so, you have qualified yourself as an innovative user of state-of-the-art technology. Since analog delay technology first came to the consumer market in the early seventies, desig

3、n engineers and manufacturers have steadily increased the performance and features available in signal processing equipment. We feel the TFX4 represents the very latest in application of electronics to live performance time effects processing. To properly set-up and familiarize yourself with the TFX

9、 QUALIFIED SERVICE PERSONNEL. 2.0 INITIAL SETUP The TFX4 is equipped to interface with a wide variety of input sources including high level microphones, electric instruments, and mixing consoles. Since the INPUT is high impedance, it will function properly with both low or high impedance sources. A.

10、 To prepare the TFX4 for first use, set the front panel controls as shown below: B. Connect your input source to the INPUT jack on the rear panel. C. Connect the EFFECT OUTPUT to your amplifier input or mixing console effects receive input.The DIRECT OUTPUT would be used with a second amplifier for

11、stereo effects. D. Connect the REMOTE IN jack to the TFX4 CONTROLLER with the 1/4-inch STEREO CORD (included). E. With the INPUT and OUTPUT jacks properly terminated, apply power to the unit by connecting the A.C. CORD to a grounded outlet and select the ON position of the rear panel POWER SWITCH. M

12、ake sure your amplifiers input level is set at minimum before selecting the ON position of the TFX4 to prevent turn-on thump. 2.1 INPUT/OUTPUT LEVEL ADJUSTMENT 1. As your instrument or signal source is applied to the TFX4, slowly turn the INPUT LEVEL control clockwise until the CLIP LED begins to fl

13、icker. The LED should flicker only on the strongest notes or signals. Never set the INPUT LEVEL control so the LED is constantly on. 2. The OUTPUT LEVEL control can be set to suit your needs. In general, guitar level signals will have the control set in its mid-scale or higher. Line level signals wi

14、ll generally require positioning the control in a counterclockwise position. Page: 3 You can use the TFX4 as a pre-amp for your instrument in either a selected effect mode or in the bypass mode. It can also boost your signal to overdrive a guitar amp. Remember, proper setting of the INPUT/OUTPUT LEV

15、ELS is necessary to achieve maximum performance with the least amount of noise and distortion. 3.1 TFX4 CONTROLLER The TFX4 CONTROLLER provides remote footswitch control of the effect mode and BYPASS function. The 20-foot long, 1/4-inch STEREO CORD allows convenient placement of the CONTROLLER on-st

16、age for live performances. Should a longer cord be necessary, use a high-quality stereo headphone extension cord with a female jack. The logic controlled switching circuitry in the TFX4 rack unit permits cable lengths up to 500-feet without any loss of switching ability. When one of the effect modes

17、 is remotely selected with the smooth operating momentary footswitch, the effect is accessed and its corresponding LED is illuminated on the TFX4 rack unit. 3.2 SELECT SECTION The six SELECT pushbuttons on the front panel are used to switch between the delay modes or bypass them and also change the

18、phase of the delayed signal with the INVERT switch. BYPASS MODE The straight signal is passed and no effect mode LEDs are illuminated. The output is free from any processing other than the interaction of the INPUT and OUTPUT LEVEL controls. EFFECT MODES When any one of the effect modes is selected:

19、FLANGER, CHORUS, DOUBLER or ECHOits corresponding section is now processing the input source and its corresponding LED is illuminated. Figure 3.2 EFFECT MODE LED COLOR CHART EFFECT MODE LED COLOR FLANGER YELLOW CHORUS RED DOUBLER GREEN ECHO ORANGE INVERT When the button is engaged, the delayed signa

20、ls phase is reversed. Inversion of the delayed signal results in altered phase cancellations, especially useful in the FLANGER mode with regeneration. Page: 4 3.3 FLANGER CONTROLS DELAY Sets the static delay time. WIDTH Determines the mix between the DELAY control and the SPEED control. As the WIDTH

21、 control is turned clockwise, the SPEED is swept over a wider range. SPEED Sets the rate at which the FLANGER sweeps up and down. HEGEN Determines the amount of the delayed signal feedback to the delay line input. Increasing the REGEN level setting from 0 to infinity tends to sustain sounds and crea

22、te resonant effects. Page: 5 3.4 CHORUS CONTROLS DEPTH Determines the range of delay time over which the RATE control will sweep. At minimum DEPTH settings effects will be very subtle. RATE Sets the speed at which the CHORUS sweeps. Page: 6 3.5 DOUBLER CONTROLS DELAY Adjusts the length of the delay

23、time. MIX Mixes between the DOUBLER delay signal and dry input signal. REGEN Determines the amount of the delayed signal feedback to the delay line input. Increasing DOUBLER regeneration adds sustain and produces hard reverb effects. Page: 7 3.6 ECHO CONTROLS DELAY Adjusts the length of the delay ti

24、me. MIX Mixes between the ECHO delay signal and dry input signal. REGEN Determines the amount of the delayed signal feedback to the delay line input. Increasing ECHO regeneration produces reverb at shorter delay settings and repeat echoes at longer delay settings. Page: 8 4.0 specifications BACKGROU
