If the MAC 4200 amplifier is not going to be used, insert a pair of non-shorting phono plugs in the POWER AMP IN jacks to disconnect it from the preamplifier output.

USING THE PUSHBUTTONS TAPE PUSHBUTTONS: The MAC 4200 is designed so it may be used with two tape recorders. Four TAPE pushbuttons control the signal inputs and outputs of the tape recorders. Recordings can be monitored as they are being recorded. Tapes can also be copied from one recorder to another while listening to a different program source. -

MONO The MONO pushbutton switches the audio output of the receiver from stereo mode to MONO. When the IN- PUT SELECTOR is in the FM position and tuned to a stereo broadcast the FM MPX light will remain on regardless of the position of the MONO pushbutton. - Page 14 response is electrically flat. As the control is turned clockwise, both bass and treble frequencies increase in the correct proportion to each other. The contour is not affected by different settings of the VOLUME control. VOLUME The VOLUME control is a precision step control manufactured for Mclntosh Laboratory.

For instance the batteries will charge should you wish to play records, or tape on FM. To bring the batteries to full charge, operate for twenty-four con- tinuous hours.
- Page 16 SIGNAL/TUNING INDICATOR The SIGNAL/TUNING indicator is to the right of the sta- tion display area. The vertical column of LED indicators show the relative signal strength of an AM or FM station being received. The greater the number of dots il- luminated, the greater the received station's signal strength.
- Page 17 POWER GUARD* POWER GUARD* assures that the amplifier can not be overdriven so amplifier output clipping is eliminated. Clipping is caused when the amplifier is asked to produce more power output than it can deliver with low distor- tion. Amplifiers are capable of delivering large quantities of power when they are driven to clipping and can have more than 40% harmonic distortion.
