DISCRETE FM/AUX In this position, the addition of an accessory 4-CH decoder will permit the reception of discrete FM. This position, when not being used for discrete FM, may be used as an additional 4-CH/AUX position. As soon as an FM broadcast system has been selected, Harman/Kardon will be in the position of supplying an appropriate decoder. MID RANGE CONTROL In addition to the normal BASS and TREBLE controls, we have incorporated a MID RANGE control which offers wide latitude of adjustment over the entire mid range of frequencies. You may now add depth and dimension to the low, mid range or high frequencies or mask excessive harshness in a recording that is excessively bright. DISCRETE PHONO/AUX This selects the four discrete phono/aux receptacles on the rear panel for playback through your system (tape recorder, cartridge player, discrete phono system) with appropriate decoder. This quadriphonic system is different than the SQ matrix design and requires a special decoder between your phonograph and Harman/Kardon 150+ receiver. Your phonograph should employ a high compliance, low tip-mass phono cartridge capable of extending in frequency response to beyond 45,000 Hertz to play back the CD-4 disc. The special decoder should be connected to the LEFT and RIGHT FRONT/BACK DISCRETE PHONO/AUX receptacles located on the rear panel of the 150 + . (Refer to "Connecting a Stereo Record Player with 150+ Decoder"). Harman/Kardon intends to manufacture a decoder for use with discrete systems. For additional information on this system and the availability of the Harman/Kardon discrete phono decoder, write to our Customer Service Department. AM This selects the AM section of your receiver. BASS & TREBLE CONTROLS These controls are employed to set the tonal balance of your stereo or 4-CH system. The Bass control adjusts the low frequencies, either strengthening or diminishing the intensity of these sounds. The Treble control adjusts the higher frequencies in the same manner - either strengthening or diminishing the sound. In most instances these controls will be set to the "flat" or center position. If bass or treble adjustment is necessary, do not rotate these controls to their maximum settings. This may introduce distortion especially if your speakers cannot handle the power of the boosted sound. These controls should be used sparingly and with the knowledge that live music is neither excessively sharp or boomy. You may adjust both the BASS and TREBLE for front and back pairs of speakers simultaneously or individually. The inner knobs adjust the front speakers and the outer knobs, the back speakers. In order to adjust both pairs, turn both inner and outer knob. In order to adjust front or back only, hold one knob while adjusting the other. MODE SWITCH This switch allows you to select the proper mode of operation for the various sources available. MONO In this position, all program sources will be reproduced in the monophonic mode. If an external monophonic source (one channel) is used it MUST be con- nected to the appropriate LEFT FRONT input receptacles in order to reproduce g sound in all speakers. The mode indicator light will be illuminated indicating a monophonic mode of operation. STEREO In this position, all stereophonic program sources will be reproduced in the STEREO mode. All pairs of speakers connected to the FRONT terminals will reproduce stereo program material. With the STEREO/QUAD REAR PANEL SWITCH in QUAD position, speakers connected to the BACK terminals will also reproduce stereo in each pair. 6 In the STEREO position, the mode indicator light will be illuminated indicating a stereophonic mode of operation. SQ MATRIX/SQ MATRIX BLEND These positions may be used to reproduce all SQ program material. In the SQ MATRIX and SQ MATRIX BLEND positions the 4 EI 4 mode indicator lights will be illuminated. These lights denote the methods used from the source material to the recording, to reproduction. The SQ MATRIX BLEND position performs the same function as the SQ MATRIX position except that it changes the relationship of separation between the LEFT and RIGHT and FRONT and BACK speakers. 7
