Carrozzeria (Pioneer) DEH-313
24 September 2026
The Carrozzeria DEH-313 is a single-DIN main unit with a CD transport and an FM/AM tuner. Pioneer's description on the manual cover is CD/チューナープレーヤー. Mounting dimensions are 178 x 50 x 162 mm with a nose of 170 x 46 x 14 mm and a mass of 1.3 kg excluding the cord unit.
The CD section is specified with 44.1 kHz sampling and 16-bit linear quantisation, a frequency response of 5 -> 20,000 Hz within plus or minus 1 dB, signal-to-noise of 94 dB at 1 kHz on the IHF-A network and dynamic range of 92 dB.
The equaliser is listed as a three-band type with plus or minus 12 dB of adjustment on each of its low, middle and high bands. Unlike the DEH-003 and the MEH-P515, the DEH-313 specification gives no centre frequencies and no Q factors for those bands, so it is documented as a three-band equaliser rather than a parametric one.
The loudness contour is specified at three levels, from 3.5 dB at 100 Hz on the low setting to 11 dB at both 100 Hz and 10 kHz on the high setting, measured at minus 30 dB volume. Output is rated at 22W x 4 across 50 -> 15,000 Hz at 5 percent THD with a maximum of 50W x 4.
Tuner performance is quoted below the DEH-003 on two counts: 70 dB signal-to-noise against 75 dB, and 40 dB stereo separation against 45 dB. Its AM selectivity is given as 50 dB where the DEH-003 is 65 dB. The supplied parts list covers the cord unit, mounting screws and documentation, with no remote control and no specified pre-out.
