- Liner Notes
The 4270 is a high quality stereo and quadradial 4-channel receiver developed by Marantz. The unit incorporates Marantz's exclusive Vari-matrix circuit which simulates 4-channel sound from normal 2-channel stereo programs, and is capable of reproducing 4-channel sound from any matrix encoded source. The 4270 will also reproduce any discrete 4-channel program as well as regular stereo and monaural programs.
An optional plug-in decoder adapts the unit receiver for any specific matrix system such as Columbia's SQ.
- Packing
- Prepare to be impressed. We have arguably the best packing process around. We use our InstaPak machine and white open cell foam to build a custom enclosure for your piece that ensures that it's stable and secure. If it is particularly fragile or heavy, we typically opt for private courier delivery. Depending on where you are in the country, that may cost a bit extra.
- Shipping
- This piece ships to the contiguous United States for a flat rate of $150, which includes our packaging and our insurance. Of course, we'll ship anywhere in the world, just drop us a line and we'll give you an estimate – even if you're just curious.
