11、nt the leakage of AC line hum into the audio circuitry). Page 2 of 2 REMOTE Remote control of EFFECT BYPASS and REPEAT HOLD functions. RadioFans.CN 收音机爱 好者资料库 ADA S1000 owners manual version 1 Used with standard ” stereo cord and dual footswitch (momentary type). EFFECT OUT A 600 ohm unbalanced outp

12、ut. The level is set with the OUTPUT LEVEL control and carries the mix of dry and delayed signal set by the OUTPUT MIX control. DIRECT OUT A 600 ohm unbalanced output of dry signal only. The level is the same as the input signal level. INPUT An unbalanced high impedance input which interfaces with l

13、ow or high impedance sources and low and high signal levels. FIGURE 3-1 INITIAL FRONT PANEL SET-UP / ONE SECOND DIGITAL DELAY 3.0 INITIAL SET-UP ADA DIGITALS interface with a wide variety of input sources including high level microphones, electronic instruments and mixing consoles. The INPUT circuit

14、ry is high impedance which functions properly with both low or high impedance sources and low (-10dBV) and high (-24dBV) signal levels. (A) To prepare your DIGITAL DELAY for use, set the rear panel POWER SWITCH to the OFF position. Also set your amplifiers power switch to the OFF position. (B) Conne

15、ct your DIGITAL DELAYS AC CORD to a grounded outlet. (C) Set the front panel controls as shown above (Figure 3-1). (D) Connect your signal source to the INPUT jack located on the rear panel. (E) Connect the EFFECT OUTPUT on your DIGITAL DELAY to your amplifier input or mixing console effects receive

16、 input. The DIRECT OUTPUT is used with a second amplifier for stereo effects. (F) Select the ON position of the rear panel POWER SWITCH (the TRIANGLE LED should now be lit), then set your amplifiers power switch td the ON position. (G) Engage the EFFECT IN pushbutton. Your DIGITAL DELAY is now ready

17、 for operation 3.1 INPUT/OUTPUT ADJUSTMENT (A) The HEADROOM LED Meter provides accurate monitoring of the input signal level relative to the clipping level. To properly set the input level find the strongest signal or musical passage that you will put into your DIGITAL DELAY and set the INPUT LEVEL

18、control to just barely light the red 0dB HEADROOM LED. The LED should flicker only on the strongest signals or notes Never set the INPUT LEVEL control so the 0dB LED is constantly on. Note that the HEADROOM LED Meter monitors all signals entering the delay line. The REGENERATION LEVEL control may ef

19、fect the headroom and therefore the readings. While performing, always remember to monitor the HEADROOM LED Meter for possible overloads. (B) The OUTPUT MIX control mixes the processed signal with the dry input signal. For use with instruments, the control will most often be in its center range. For

20、 studio applications where your DIGITAL DELAY is in an effects loop, the MIX control is most useful in the full clockwise, DELAY position. The processed signal level (and thus the dry/effect mix) is now controlled at the console. (C) The OUTPUT LEVEL control sets the level of the EFFECT OUTPUT wheth

21、er in bypass or effect IN mode. In general, guitar level signals will have the control in its mid-scale or higher, line level signals will generally require positioning the control more counter-clockwise. Remember, proper setting of me INPUT/OUTPUT LEVEL controls is necessary to achieve maximum perf

22、ormance with the least amount of noise and distortion. Page 3 of 3 ADA S1000 owners manual version 1 3.2 REMOTE FUNCTIONS EFFECTS BYPASS and REPEAT HOLD are remotely controllable via the rear panel jack labeled REMOTE. The stereo cord connects with two momentary footswitches. In the EFFECT BYPASS mo

23、de, the input signal source is routed to the EFFECT OUTPUT BYPASS is actuated by a momentary closure which grounds the tip to the sleeve. The REPEAT HOLD function allows non-deteriorating repeat of any source stored in the delay memory. REPEAT HOLD is actuated by a momentary closure which grounds th

24、e ring to the sleeve. Note that the front panel switches may also be used while the dual footswitch is connected. 3.3 REGENERATION SECTION As the REGENERATION LEVEL control is turned clockwise, more of the delayed audio signal is sent back to the input of your DIGITAL DELAY. When using short delay s

25、ettings, from 0.5 to 40ms, the REGENERATION LEVEL control adds emphasis or resonance to flanging and chorusing. At longer time delays, from 64 to 1024ms, the REGENERATION LEVEL control adds repeat echos extending to 50 seconds or more. 3.4 REPEAT HOLD When engaged, the REPEAT HOLD pushbutton will ca

26、pture and repeat the signal stored in memory indefinitely without any loss of audio quality. Up to 1024ms of a musical passage may be repeated as a counterpoint or a background rhythm.When your DIGITAL DELAY is initially powered up, an ( internal protection circuit defeats the REPEAT HOLD function t

27、o prevent howling/ 3.5 PHASE The delayed signals phase is inverted when the PHASE pushbutton is engaged. Inverted phase may correct phasing problems in mixing consoles, or alter the tonal characteristics of short delay effects such as resonant flanging and doppler chorusing. 3.6 DELAY SECTION The DE

28、LAY MULTIPLIER control allows continuous 0.125X to 1X adjustment of the delay time selected from any one of the interlocking DELAY range pushbuttons. The ranges of each of the DELAY pushbuttons are as follows: FIGURE 3-2 - S1000 DELAY TIME RANGES 3.7 MODULATION The MODULATION DEPTH control allows yo

29、u to fade between the static setting of the DELAY MULTIPLIER control and the sweeping voltage of the internal low frequency oscillator. When the DEPTH control is set at 0, the delayed signal is not swept and the delay time remains stationary. As the DEPTH control is turned clockwise, a wider range o

30、f the selected time delay is swept. With the DEPTH control set at 10, the full 8:1 range is swept and the MULTIPLIER control is disabled. At settings less than 10, the MULTIPLIER sets the center of the sweep range. The MODULATION SPEED control adjusts the low frequency oscillator from 0.1 sec to 25s

31、ec. Extremely slow sweeps are useful for chorusing, flanging and subtle effects. Faster sweeps can produce vibrato, fast flanging and rotating speaker simulation. Page 4 of 4 ADA S1000 owners manual version 1 4.0 PATCH DIAGRAMS FIGURE 4-1 CLASSIC FLANGE This demonstrates the full 8:1 sweep range of

32、your digital delay. Turning the REGENERATION LEVEL control clockwise produces more resonant or more dramatic flanging effects. FIGURE 4-2 EVEN/ODD HARMONIC At minimum MULTIPLIER control settings, switch between in-phase and out-of-phase settings with the PHASE switch. Inverted signals will cancel lo

33、wer-frequencies thereby apparently emphasizing treble content. FIGURE 4-3 THICK CHORUS This is a dramatic, very deep chorus. Adjust the SPEED control for the desired effect. FIGURE 4-4 LESLIE CHORUS This simulates the popular rotating speaker effect. FIGURE 4 5 STEREO DOUBLING The OUTPUT MIX control

34、 is set at full delay (10) for double tracking when using the DIRECT OUTPUT and the EFFECT OUTPUT in a stereo PA or recording system. In mono systems, set the OUTPUT MlX control in its center position (5). A single short repeat of the note or chord is produced for added thickness. FIGURE 4-6 REPEAT

35、ECHO By carefully adjusting the REGENERATION LEVEL control, you can select from one repeat to multiple repeats lasting 30 seconds or more, Page 5 of 5 ADA S1000 owners manual version 1 FIGURE 4-7 REPEAT HOLD This captures, stores, and repeats a segment of sound without signal degradation. The pitch

36、and repeat rate may be modified by using the DELAY MULTIPLIER control Many useful special effects can be produced by varying the MODULATION DEPTH and SPEED controls. The key to using Repeat Hold is to depress the REPEAT HOLD button after the passage has been played. FIGURE 4-8 REVERB Mixing a higher
