(1) ? FX-7000 PRO STEREO MIXER WITH DSP EFFECTS CONTENTS: Connections refer to D.S.P. EFFECTS (54) for which effect you want to use. Displayed by the PARAMETER LED DISPLAY (55). The effects parameters (1-99) can be adjusted using the PARAMETER (56) knob. DSP EFFECTS (54): All the DSP effects are listed on the mixer here. Turning the PARAMETER (56) knob clockwise increases the effect in most cases. Here is a brief explanation of their uses: 01. SEND/RETURN: Used to connect outboard effect units. 02. DELAY: Delay effect; adjust time with PARAMETER (56) knob. 03. ECHO REGULAR: Echo effect, adjust time like delay effect. 04. PING PONG ECHO: Echo effect with left/right panning, adjust time like delay effect. 05. REVERB: Reverb effect for depth, adjust time just like delay effect. 06. PITCH UP: Increases the pitch of the selected CHANNEL, Mic 1 or MASTER (PGM). 07. PITCH DOWN: Decreases the pitch of the selected CHANNEL, MIC 1 or MASTER (PGM). 08. FILTER 1: Low pass filter increases with clockwise knob movement. 09. FILTER 2: High pass effect increases with clockwise knob movement. 10. BRAKE: Simulates the manual stop of a record on a turntable. 11. AUTO PAN: Automatic panning from left to right, turning knob clockwise increases the effect speed. 12. FLANGER: Flanger sound is an effect, which is often referred to as a “whooshing” or “airplane fly-by” sound, turning knob clockwise increases the intensity of the effect. 13. PHASER: Very close to flanger, phaser is a similar but different effect. 14. ROTARY: Simulates a rotating speaker effect. 15. AMBIENCE: Adds ambient effect to mix. 16. PRESET REVERBS: F1. HALL 1, F2. HALL 2, F3. ROOM 1, F4. ROOM 2, F5. ROOM 3, F6. PLATE 1, F7. PLATE 2, F8. PLATE 3, F9. ROOM CHORUS PARAMETER LED DISPLAY (55): The PARAMETER LED DISPLAY (55) displays which effect is chosen as well as the parameters. PARAMETER (56): The PARAMETER (56) knob changes the effects parameters from (1-99), except for effect number 1. However effect number 16, has 9 different preset reverb settings (F1- F9). WET/DRY (57): Turning the WET/DRY (57) knob lets you pan the selected effect into and out of the PGM (program) SPECIFICATIONS: AUDIO SECTION: INPUT TERMINAL (input level/impedance) gain max.: LINE 1, 2 , 4.-20dB(100mV) 47 KOhm LINE 3, 5.-20dB(100mV 13 KOhm PHONO 1, 2, 3.-54dB(2mV) 47 KOhm MIC 1, 2.-56dB(1.5mV) 2 KOhm (Balanced) RETURN.-20 dB (100mV) 5 KOhm OUTPUT TERMINAL (output level/impedance): MASTER OUTPUT (RCA).0 dBV (1V) 300 Ohm MASTER OUTPUT (1/4 BALANCED).6 dBV (2V) 600 Ohm REC OUTPUT .-18dB(120mV) 5 KOhm ZONE MONITOR.0 dBV (1V) 300 Ohm SEND.-18dB(120mV) 2 KOhm PHONES.0 dBV (1V) 47 Ohm FREQUENCY CHARACTERISTICS: LINE/MIC.20Hz 20 kHz (+/-2dB) PHONO (RIAA).20Hz 20 kHz SN RATIO (with effect off). better than 80dB TOTAL HARMONIC DISTORTION.rate less than 0.02% CHANNEL EQUALIZER (LINE, PHONO, MIC 2); HI.+12 dB, -32 dB MID.+12 dB, -32 dB LOW.+12 dB, -32 dB MICROPHONE EQUALIZER (MIC 1): HI.+12 dB, -12 dB LOW.+12 dB, -12 dB TALKOVER ATTENUATION.16dB ELECTRICAL SECTION, ETC.: POWER SUPPLY VOLTAGE.AC 18 V, 50-60 Hz (from adapter) POWER CONSUMPTION.20 W OPERATING TEMPERATURE.+5C to +35C (+41F - +95F) OPERATING HUMIDITY.5% to 85% EXTERNAL DIMENSIONS.254(W) 355 (D) 110 (H) mm/10(W) 14 (D) 4-1/3(H) in.
