How to Connect 

Rear panel input jacks are provided for 2 stereo 

high level sources (AUX 1 and AUX 2), a stereo tuner 

(TUNER), 2 stereo turntables (PH 1 and PH 2), stereo 

high impedance microphones (MIC), and 2 stereo 

tape recorders (TAPE 1 and TAPE 2). 

Rear panel output jacks are provided to feed 2 

stereo tape recorders (TAPE 1 and TAPE 2), a stereo 

600 ohm unbalanced line (LINE) and 2 stereo 2.5 volt 

outputs (MAIN). 

Front panel jacks provide input and output 

facilities for a tape recorder using the circuits of the 
rear panel TAPE 2 connections. Two headphone 

jacks are provided which are fed by a stereo 

amplifier in the C 29. 

CONNECTING AUX 1 AND AUX 2 

Connect the left channel cable from any high level 

source (tuner, TV set, tape recorder, etc.) to the IN-

PUT AUX 1 left jack. Connect the right channel cable 

to the INPUT AUX 1 Right jack. A second high level 

source can be connected similarly to INPUT AUX 2. 

CONNECTING TURNTABLES 

The C 29 has shorting plugs in the phono inputs. 

To prevent unwanted noise remove the shorting 

plugs only from input jacks that are to be used. Con-
nect the cable from the left channel of the turntable 
into the INPUT PHono 1 left jack. Connect the cable 
from the right channel of the turntable into the IN-

PUT PHono 1 Right jack. For a second turntable, 

connect PHono 2 in the same way, after removing 

the shorting plugs. 

CONNECTING MICROPHONES 

Connect the cables from high impedance 

microphones directly in the INPUT MIC Left and 

Right jacks. 

CONNECTING TAPE RECORDERS 

To Record: 

Connect a cable from the OUTPUT TAPE 1 Left 

jack to the left high level input of the tape recorder. 

Connect a cable from the OUTPUT TAPE 1 Right jack 
to the right high level input of the tape recorder. Con-

nect a second recorder in the same manner to the 

OUTPUT TAPE 2 jacks. 

To Playback/Monitor: 

Connect a cable from the left channel output of a 

tape recorder to the TAPE INPUT 1 Left jack. Con-

nect a cable from the right channel output of a tape 
recorder to the TAPE INPUT 1 Right jack. Connect a 
second recorder in the same manner to the TAPE IN-

PUT 2 jacks. 

Front Panel Tape Recorder Jacks: 

Tape recorder inputs and outputs are available at 

the TAPE IN-OUT jacks on the front panel just to the 

left of the TAPE MONITOR pushbuttons. These 

jacks make connections to TAPE 2 facilities without 

having to go to the rear panel. A metal shielded 1/4 
inch stereo phone plug is used. Connections are tip: 
left signal, ring: right signal, and sleeve: common 

ground.
