Denon DRA-335R Service Manual

Specifications and Main Features

The model is DRA-435R.
The maximum sound output is as follows:
For DRA-435R and DRA-335R, 55 watts and 40 watts respectively with RMS driving not exceeding 0.05%.
If we were to put the IHF indicator into consideration, the power output would be `10 Hz - 40 kHz (T.H.D. 0.15% both channels driven into 8 ohms)`
The harmonic distortion rate has been measured to be 0.03%
The CD and VIDEO output brings in 20 Hz - 5 KHz with a harmonic distortion of 1.5dB
MM when put on 2.5mV at a frequency of 47K ohms becomes the minimum impedance level on the PHONO port while sitting at 150mv at kanda 29ohms becomes the output on the CD and VIDEO ports.
The amp output across the range of 1kHz swings across MM 120MV which turns out to be the inphi output for PHONO
The noise ratio output according to IHF-A for PHONO MM at 5MV is 78dB while for CD, VIDEO, TAPE-1, TAPE-2/VCR it swings up to lower 96dB
Taking the HW and SW into account, the BASS has been measured to be -10dB while the TREBLE is +10dB.
Control Effects of the Loudness as Sound System control with DRA-435R is set to have a variable loudness across 10 positions with a frequency response of 50 Hz/10 KHz with a gain of +10 dB/+5 dB.
The Doppler Holographic Acoustic Impact Field outputs through the Pre-Out terminals compatible with the DRA-435R is rated at 2V with a load of 100 ohms.
With the video section NWA 9700 X series, the DRA-435R is tested and found to Respond from a Frequency of 5HZ to 6 Mhz boosting by upto 1.5 decibels.
The Subwoofer production Adapters and Modules with DRA-435 owe a Frequency Range of FM 87.5 to 108 MHZ, AM 520 to 1710 kHZ.
As for sensitivity with SCHA12v Range output modules:
FM: 0.9 uV at 10.3 dB, MONO at 1.6 uV at 15.3 dB, STEREO usage at 23uV at 38.5 dB.
AM: Usable input 18 pV.
As a ratio analysis regarding the even harmonic distortion ratio it can be concluded that:
For FM: MONO at 82dB and STEREO at 78dB.
AM: 55 dB.
With a general power supply of 120 volts with a frequency of 60 Hertz, the modifiers DRA-435R and DRA-335R have a power consumption of 264 watts and 180 watts.
With US standards the dimensions of the Device were measured to be: Width: 434 mm, Height: 120 mm Depth: 312 mm.
The weight of the machine DRA-435R approximately weighs around 6.7 kg while DRA-335R weighs 6.4 kg.
As for remote control units DRA-435R utilizes RC-129 whereas DRA-335R implements RC-129A, Both units are Chargeable consuming 3V DC with 2 AA dry cell batteries.
Driven Transmitter and Receiver Units: 3V IR pulse system added with

DRA-335 uses RC-129A Remote Control through IR pulse system.
