Now connect the program sources in the following fashion: 1.) Plug one end of the 3 foot shielded lead into the jack marked "MAIN OUTPUT" located on the back panel of the C-8. 2.) The C-8 "VOLUME" control on the front panel is turned fully clockwise. The changes in volume will be controlled by the C-8S ganged "VOLUME" control. 3.) Insert the left channel phono cartridge lead in "PHONO #2" on the C-8. 4.) If a tape deck is used for stereo playback, insert left channel lead into "MIC" input of the C-8, serial #10600 and above, after conver- sion as in section A, step #4 above. This input is terminated at 100,000 ohms. N.A.R.B. tape playback equalization is achieved by depressing the Bass Compensation switch labeled "950", adjusting the "BASS" tone control to - 1, and adjusting the "TREBLE" tone control to- 2.5. If a stereo tape playback with preamplifiers is used, insert the left output in the channel marked "TAPE". Next interconnect the C-8S: 1.) Plug the heavy inter-unit cable from the C-8S in the octal socket marked "Pre-Amp" on the right power amplifier. 2.) The loose end of the 3' shielded lead (section B, step #1) from the C-8 "MAIN OUTPUT" is plugged into the "LEFT STEREO IN" on the C-8S. 3.) Interconnect by means of one of the 6' shielded cables between the jack marked "LEFT STEREO OUT" on the C-8S and the "0.5 VOLT" input of the left power amplifier. 4.) Interconnect by means of the other of the 6' shielded cables between the "MAIN OUTPUT" on the C-8S and the "0.5 VOLT" input on the right power amplifier. 5.) Plug the A.C. cord from the C-8 into one of the auxiliary A.C. receptacles on the C-8S. 6.) The A.C. cords from both power amplifiers can now" be plugged into the auxiliary A.C. plugs on their respective preamplifiers. The on-off switch on the volume control of the C-8S now controls turning on the entire system. (c.) (B.) -2-

Connect the program source equipment to the C-8S as follows : 1.) Plug the right channel phono cartridge lead into the C-8S input marked "PHONO #2". 2.) Connect the output of the right channel tape head to the input marked "TAPE HEAD". For N.A.R.B. equalization from a tape head, depress the bass compensation switch labeled "950", adjust "BASS" tone control to - 1, and "TREBLE" tone control to - 2.5. 3.) If a tape recorded with preamplifiers is used, plug the output of the right channel into the input marked "TAPE". 4.) If a monaural cartridge is used, plug it into "PHONO #1". 5.) Connect a tuner output to input marked "TUNER", The balance of the stereo system will be maintained in all modes of operation by following these system balancing instructions: 1.) Turn input selector switches on both preamplifiers to "PHONO #2". 2.) Turn the stereo "MODE" selector switch to "MON RIGHT". 3.) Adjust the "BALANCE," "BASS," and "TREBLE" controls to 12 o'clock. 4.) Adjust the RECORD COMPENSATOR" to RIAA settings. 5.) Adjust the "INPUT LEVEL CONTROL" on both compensator "PHONO #2" channels totally clockwise. A monaural record is used for correctly balancing the system. Turn up the volume control on the C-8S. With the mode selector switch in "MON RIGHT" the same signal will be heard from both loudspeakers. 6.) If the sound from each loudspeaker is not of equal loudness adjust the control marked "GAIN" on one power amplifier until the sounds from the loudspeakers are of equal intensity. Do not use the Balance Control for this adjustment. -3- (E.) (D.)
