2 fm Page 2 Thursday, September 23, :19 PM CONN NNECTIONS Follow these steps to connect the equalizer to your audio system. Cautions: Use only shielded audio cable with phono-type connectors, available at your local RadioShack store. Before you connect the equalizer, turn off all the components in your audio system and unplug their power cords. Before you plug in the equalizer s power cord, complete all the connections and be sure the equalizer s POWER button is set to the out position. Stereo Receiver Tape Deck 1 1. To connect the equalizer to your receiver, connect the receiver s left and right TAPE OUT jacks to the equalizer s L and R MAIN IN jacks. Then connect the equalizer s L and R MAIN OUT jacks to your receiver s left and right TAPE IN or TAPE MONITOR jacks. 2. You can connect a tape deck to each set of tape jacks (TAPE 1 and TAPE 2) on the back of the equalizer. To connect each tape deck, connect the equalizer s L and R TAPE OUT jacks to the tape deck s left and right IN jacks. Then Tape Deck 2 connect the tape deck s OUT jacks to the equalizer s L and R TAPE IN jacks. 3. Plug the equalizer s power cord into your receiver s switched power outlet or any standard AC outlet. Warning: The equalizer s power cord has a polarized plug. To prevent electric shock, do not use an extension cord or other receptacle unless you can fully and easily insert the plug s blades. 4. Reconnect the other components power cords. 2

3 fm Page 3 Thursday, September 23, :19 PM OPERATION Follow these steps to use the equalizer. 1. Turn the receiver s volume control to its lowest setting. Then set the receiver s tone controls to their center positions. If the audio source is a tape deck, set the appropriate TAPE MONITOR button (1 or 2) to the in position. If the source is not a tape deck, be sure both of the equalizer s TAPE MONITOR buttons are set to the out position. 2. Set the equalizer s slide controls to 0 db (center positions). TAPE MONITOR Buttons 3. Be sure BYPASS and EQ RECORD are set to the out position. If either is set to the in position, press it to release it. BYPASS Button Equalizer Slide Controls 4. Press POWER to turn on the equalizer. The SPECTRUM DISPLAY lights. 7. Start the audio source and adjust the receiver s volume. 8. Adjust the equalizer s slide controls for the desired sound (see Frequency Controls ). You can view the effect of the adjustments on the SPECTRUM DISPLAY. Note: The display shows the sound levels of the audio source you are listening to. For example, if you are dubbing from one tape deck to another but listening to the CD player, the display shows the sound levels of the CD player. 5 0 AUDIO ADJUSTMENTS Frequency Controls 5. Select the receiver s tape monitoring feature. 6. Turn on the receiver. Using the receiver s controls, select the audio source. The equalizer has separate LEFT channel and RIGHT channel controls so you can set the sound differently for your left and right speakers. 3

4 fm Page 4 Thursday, September 23, :19 PM You modify each channel s sound by moving the slide controls up or down. Each slide control affects a small range of frequencies. The frequency marked below a slide control is the mid-point of the band affected by that control. To boost a frequency band s level, slide the control above 0 db. To cut the level, slide the control below 0 db. If you do not want to change the sound level of a frequency band, leave its control set to 0 db. The following information groups the frequency bands into five ranges. This information can help you adjust the sound for the desired effect. 5 0 Mid-Range (400 2,600 Hz) Example: Most deep vocals Changes in this range cause the greatest effect. The best settings for this range vary depending on the type of music. Upper Mid-Range (2,600 5,200 Hz) Example: Most high vocals Boost these frequencies to brighten the sound. Cut these frequencies if the sound is harsh. High End (5,200 20,000 Hz) Example: Piccolo Boost these frequencies to enhance the brilliance of the music. Cut these frequencies if the sound is piercing. You can also cut these frequencies to filter highfrequency noise. Displa lay Level el Bass ( Hz) Example: Bass drum Use these controls to enhance the music s low tones or to reduce rumble, acoustic feedback, and other low-frequency noise. Mid-Bass ( Hz) Example: Bass guitar Boost the frequencies in this range if the sound is too thin. Cut these frequencies if the sound is muddy or boomy. The SPECTRUM DISPLAY shows the relative sound level of each frequency band. The highest and lowest sound levels might not fully appear. If necessary, slide DISPLAY LEVEL up to view low sound levels or down to view the peaks of high sound levels. DISPLAY LEVEL Slide Control 4

5 fm Page 5 Thursday, September 23, :19 PM Bypass Control To hear sounds without equalization (just as you would hear them with all the equalizer frequency controls set to 0 db), set BYPASS to the in position to bypass the equalizer circuit. Set BYPASS to the out position to return to equalization. Caution: To prevent overdriving your amplifier or speakers, turn down the receiver s volume control before you press BYPASS. After you press BYPASS, slowly increase the volume. Stereo Image Enhancer The stereo image enhancer lets you adjust the perceived separation between the left and right channels so you can broaden the sound field. You can use this feature to compensate for improper speaker placement or simply to enhance the stereo effect. Set IMAGE ENHANCER to the in position to enhance the stereo effect. The image enhancer indicator lights. Then adjust the ENHANCER LEVEL slide control to increase or decrease the effect. You hear the expanded sound if you monitor either tape deck. ENHANCER LEVEL Slide Control Image Enhancer Indicator IMAGE ENHANCER Button Set IMAGE ENHANCER to the out position to return to normal sound. The image enhancer indicator turns off. Note: The BYPASS control setting does not affect the stereo image enhancer operation. RECORDING AND DUBBING ADJUSTMENTS If you connect a tape deck to the equalizer as described in Connections on Page 2, you can record from any other audio source connected to your receiver. If you connect two tape decks, you can make two recordings at the same time, or you can dub (copy) a tape from one tape deck to the other. Note: If you record the sound with equalization, we recommend you play it back without equalization. If you turn on the stereo image enhancer when you record, we recommend you turn off the stereo image enhancer during playback. Otherwise, the sound might distort. The recorded sound and the sound you hear as you record depend on the following settings. EQ Record Control To record sounds with equalization while you listen to unmodified sounds, first adjust the equalizer slide controls for the sound you want. Then set EQ RECORD to the in position and BYPASS to the out position. You hear the equalized sound if you monitor either tape deck. If you set BYPASS to the 5

6 fm Page 6 Thursday, September 23, :19 PM in position, you record sounds without equalization. Stereo Image Enhancer To record sounds with enhanced stereo effect while you listen to unenhanced sounds, set IMAGE ENHANCER to the in position. Adjust the ENHANCER LEVEL slide control to increase or decrease the effect. Then set EQ RECORD to the in position. You hear the expanded sound if you monitor either tape deck. Note: The BYPASS control setting does not affect the stereo image enhancer operation. Tape Monitor To hear a tape deck s output, set the appropriate TAPE MONITOR button (1 or 2) to the in position. To stop monitoring, set 1 or 2 to the out position. Notes: Do not press in both TAPE MONITOR buttons. If you do, you mute the sound from both tape decks. Some tape decks have a tape monitoring feature. If you select your tape deck s monitoring feature, and you press in the equalizer s TAPE MONITOR button for the tape deck you are recording to, the sound you hear is the actual recording. 6 EQ RECORD Button Dubb bbing To dub a tape from Tape Deck 1 to Tape Deck 2, set TAPE DUBBING 1 2 to the in position. To dub a tape from Tape Deck 2 to Tape Deck 1, set TAPE DUBBING 2 1 to the in position. Note: Do not press in both TAPE DUBBING buttons. If you do, neither tape deck records. CARE TAPE DUBBING Buttons To enjoy your RCA 10-Band Stereo Graphic Equalizer for a long time: Keep the equalizer dry. If it gets wet, wipe it dry immediately. Use and store the equalizer only in normal temperature environments. Handle the equalizer gently and carefully. Do not drop it. Keep the equalizer away from dust. Wipe the equalizer with a damp cloth occasionally to keep it looking new. Modifying or tampering with the equalizer s internal components can cause a malfunction and invalidate its warranty.
