A A. RISK OF ELECTRI[ SHOCK. You have chosen a truly outstanding product. The Nakamlchi CA-5AlI is a control amplifier deSigned to provide superior performance and utterly pure Signal transmission , It achieves this aim without relying on a large amount of negative feedback, The Multi-Regulated Power Supply and Isolated-Ground principle effectively eliminate crosstalk and interference arising in the power supply. [. . . ] . ~ C Tape Deck 1 Recording (Output) Jacks C) Tape Monitor Switch Tape 1 For playback of a tape deck connected to the Tape 1 jacks. For playback of a tape deck Tape 2 connected to the Tape 2 jacks. Source To listen to the program source chosen with the Input selector. 2: For lape dubbing from tape deck 1 to tape deck 2. Copy 1 : For tape dubbing from tape deck 2 to tape deck 1. Tone Controls Serve to adjust the tonal balance. By turning a knob clockw ise, the respective range is emphasIzed, and by turning it one word the frequenc ies are attenuated. set the Tone switch to "On . " Bass : From the center clickstop position . adjustment is possible within the range of ± 10 dB (at 20 Hz) Treble: From the center clickstop position, adjustment is possible wi thin the range of ±10 dB (at 20 kHz) Tone Switch Setting this switch to "On" activates the tone control circuits. When the switch is set to "Off, " the circuits are bypassed and the signal Is routed directly 10 the power amplifier section, to further enhance sonic purity. o o Cartridge load/Gain Selector When a moving-magnet cartridge is used, th is switch selects the termination capacitance. With moving-coil cartridges, th e switch controls the gain of the head amplifier. o Terminal for Remote Power On/Off Switching Connect the opti onal System Power Control strip (SPC- 1) to this termina l 2" 8 Input Selector Serves to select one of the program sources connected to the CA-SAll : tuner, turntable, CD player, etc. o o o Balance Control Serves to adjust left/right speaker balance. Then insert the supplied power cord into th e AC Power con nector on the rear panel of th is unit and plu g the oth er end into an AC wall ou tl et. After all system connections are completed, make sure th at th is uni t's Outpu t Level control is turned to mini mum. Then set th is unit's Power switch to "On" and finally tu rn on the power amplifier. set the Tape Monitor switch to "Tape 1" or "Tape 2, " as requ ired. For recording on a tape deck, select the desired program source with the Input selector and set the Tape Monitor switch of th e CA- 5AII to "Source. " Then set the tape deck to the record mode. The signal supplied to the tape deck is completely unaHected by the volume, tone control and balance settings of the CA-SAIT . · The signal from the program source chosen by the Input selector is always present at both sets of tape recording outputs. Recording can therefore also be carried out on two tape decks simultaneously. When two tape recorders are connected, dubbing in both directions can be carried out easil y. To play back a tape on tape deck 1 and record it on tape deck 2, set th e Tape Mon itor switch to "Copy 1 ~ 2" To reverse the process, choose the "Copy 2~ 1" posi tion. In these switch positions, the output signal of the record ing deck is present at the preampl ifier output jacks 1 and 2. [. . . ] Movin g-coi I cartridge wilh ra ted output of less than 1. 0 mV used at "Moving Magnet" position. Load impeda nce seltin g incorrect. 1. Refer to OWrJer's Man ual of Power amplifier. No sound. Left /right channels r v rsed, no sound from one channel. 6. Route AC power lines as far as possibl e from ou tput cables and cartridge. [. . . ]
