1 mc loadS (r1, r2, r3): If you are using a Moving Coil (MC)cartridge, set this switch to a resistive load that closely approximatesthe value specified in the MC cartridge (this is usually specified in theMC cartridge). In general, use the lowest resistance for low outputcartridges and high resistance for medium output cartridges. For veryhigh output models up to 1 mV/cm/sec and internal resistance ashigh as 200 ohms, use the low or medium input resistance as you mayotherwise run into overload.The resistive values are R1= 600 ohms, R2= 100 ohms and R3=40 ohms.2 mm loadS (c1, c2, c3): If you are using a Moving Magnet (MM)cartridge, this switch selects the input capacitance of the phonopreamplifier. It enables you to optimise the load capacitance for thosecartridges whose frequency response is affected by this parameter.The selectable capacitance values are C1=220 pF, C2=330 pF andC3=400 pF.In order to select the best value of preamplifier input capacitance, youmust first determine the total capacitance recommended for the MMcartridge. This is usually included in the maker’s specifications.Next, subtract the capacitance of your turntable’s tonearm wiring signalcables. (Check the specifications supplied with the tonearm; generally,the cables has capacitance of 100-200 pF) After this subtraction, whatremains is the desired value of preamplifier input capacitance. Set theMM LOAD switch to the nearest value. It is not necessary to matchthe computed value exactly; with most phono pickups, a variation of50pF one way or the other will produce only a very slight change infrequency response.for example: Suppose a MM cartridge in a turntable has arecommended load capacitance of 275 pF and a cable capacitanceof about 100 pF. By computation, the required preamplifier inputcapacitance is 175 pF. Set the MM LOAD switch to C1.You may also set the MM LOAD switch by ear while listening torecordings that are strong in high frequency overtones. Typically, whenthe capacitance is too low, the upper midrange (the soprano voicerange) will be softened and the response at the highest frequency willbe peaky, leading to edgy violin tone and increased surface noise. Toohigh a value of capacitance will bring the upper midrange forwardwhile rolling off the extreme highs.3 mc input: Input for a Moving Coil phono cartridge. Connect the twin RCAlead from your turntable to this input if you are using a Moving Coil cartridge.4 mm input: Input for a Moving Magnet phono cartridge. Connectthe twin RCA lead from your turntable to this input if you are using aMoving Magnet cartridge.5 phono ground connector: Turntables normally includes a singlewire earth lead. Use the C 165BEE phono ground connector to connectthis lead. Unscrew the terminal to expose the hole, which will acceptthe lead. After insertion, tighten the terminal to secure the lead.6 mc-mm Switch: Slide this switch to either MM (Moving Magnet) orMC (Moving Coil) depending upon the phono cartridge being used.7 cd input: Input for a CD or other line-level signal source. Use atwin RCA-to-RCA lead to connect the CD player’s left and right “AudioOutputs” to this input.8 tuner input: Input for a tuner or other line-level signal source. Usea twin RCA-to-RCA lead to connect the tuner left and right “AudioOutputs” to this input.9 mp input: Input for a Media Player or other line-level signal source.Use a twin RCA-to-RCA lead to connect the Media Player’s left and right“Audio Outputs” to this input.10 aux input: Input for additional line level input signals such asanother CD player. Use a twin RCA-to-RCA lead to connect the auxiliaryunit’s left and right “Audio Outputs” to this input.11 tape 2 in/out: Connections for analog recording and playback to anaudio tape recorder of any type. Using twin RCA-to-RCA leads, connectto the left and right “Audio Output” of the tape machine to the TAPE 2 INsockets for playback. Connect the left and right “Audio Input” of the tapemachine to the TAPE 2 OUT sockets for recording.IDENTIFICATION OF CONTROLSrear panel3 987 10 11 12 13 14 15 172120191816ATTENTION!Please make sure that the C 165BEE is powered off or unplugged before making any connections.
