Big QUAD receiver in elegant two-tone color, from when Quadro-sound was on the verge of loosing its attraction potential.
The KR-7340 can power eight loudspeakers, decode all Quad formats and do all the tricks serious Quad units can like converting a mono or stereo source into a 4-channel signal, see through the SQ format, the RM and Discrete modes, set volume, balance, bass and treble separately for the front and rear speakers, record to tape in Quad (or not), power two sets of Quad 'speakers in two different rooms, plug a MICrophone in to spread your voice over said rooms, and flash plenty of lights at its proud and singing (if a little lost) owner.
The VU meters can be switched to a +20dB sensitivity - really serious Quad unit !
There are four separate amplifiers in which can be bridged for higher output power in 2-channel mode ; the switch is at the back, under the speakers' terminals and 2-CH has to be selected.
The FM part starts with a FET input and two ceramic filters, while the MPX block works alongwith Kenwood's DSD circuit ("double-commutation demodulator").
The FM-DET ouptut allows to receive Dolby FM broadcasts - or should have allowed it.
The KCD-2 optional module allows to decode CD-4 (JVC's Quad format) which wasn't that widespread so Kenwood lowered production costs by making it an option and not a fixture.
The strange and strangely named "Radar" mode indicates that a CD-4 disc is being played - why "radar" was chosen will remain in the dark.
Just above was the technically equivalent KR-8340 (KR-8840 in the US) which mainly offered more power output. But the KCD-2 still was an option for most markets.
The KR-9340 (KR-9940 in the US) was the Quad topper bringing more power and an added FM center tuning meter - a topper after which Quad disappeared from the Kenwood catalogs.
