Harman Kardon RHK670 Owners Manual - Page 9

TAPE MONITOR switch to TAPE 1 or TAPE 2. When the switch is set to TAPE 1 or TAPE 2 the red LED (40) above the switch will glow. Note that as long as the switch is set to TAPE 1 or TAPE 2, no sound will be heard from any other program source, regardless of the position of the FUNCTION control. The hk670 is a high-quality precision instrument. If the instructions in this manual are followed thoughtfully, the receiver should provide many years of musical pleasure. To Record Tapes The TAPE OUT jacks allow you to record program material from any source selected by the FUNCTION control. The VOLUME and BALANCE controls, and the various tone controls do not affect the signal at the TAPE OUT jacks. Hence you can change the settings of these controls without altering a tape recording in progress. If your tape deck has a separate monitor head, you can use the TAPE MONITOR feature of the hk670 to compare the original source with the recording. Set the TAPE MONITOR switch (39) to the appropriate position (TAPE 1 or TAPE 2), and you will hear the recording a fraction of a second after it has been made. Return the TAPE MONITOR switch to SOURCE, and you will hear the original source. The hk670 also provides the ability to record directly from one tape deck to another, while you listen to a separate source (such as records or FM) as the tape is being copied. With the TAPE COPY switch (41) set to 1 TO 2 you can copy a tape from deck 1 onto deck 2. With the switch set to 2 TO 1, you can copy from deck 2 onto deck 1. At any time, you may listen to either tape by setting the TAPE MONITOR switch (39) to TAPE 1 or TAPE 2. When you have finished making the copy, return to TAPE COPY switch to the SOURCE position. Speaker Protection An electronic circuit in the hk670 protects your speakers from short circuits and other conditions of excessive current. Resetting is automatic. Maintaining Appearance Clean the metal panel with mild, diluted detergent applied with a soft cloth or cotton swab. Never use a strong abrasive cleaner. Remove dust or smudges from the acrylic front window with diluted glass cleaner applied with a soft cloth. Do not use a strong solvent-type cleaner or ammonia.
