0 Discrete Left and Right channel 18-bit D/A converters with Opto-Drive'
Onkyos Optor Drive is a revolutionary new type of steady state current supply which ensures that the output from the WA converters
is completely free of electromagnetic interference. Instead of using a conventional zener diode as a current source, Opto-Drive uses a
phoiotransistor to convert light energy Into electricityThe output is then amplified and used as the steady state current supply
Both the DXE7500 and DX-SSOO feature two such"0piOEDrive D/A converters one each for the left and right channel signals. Using
discrete D/A converters eliminates phase differences between the stereo channels which can cause muddy, unfocused sound.
Finally, true 18-bit D/A conversion expands dynamic range and S/N ratio 7 a significant advance compared with earlier 14, or lSEbit
systems. Delicate musical nuances which could be masked by noise from semiconductors, etc. in conventional CD players emerge with

crystal clarity for stunningly vibrant, detailed sound reproduction.

0 Opto-Coupling

Onkvo's OptoECoupling keeps digital pulse noise out of the analog circuitry by electrically isolating the digital block Beams ol light,
not electricity, transmit the necessary signals via a "bridge" composed of photocoupleis and Onkyos "OptorCoupling Modules " (In
the DXE7500, a full Six data signals are transmitted optically, two Via Cote-Coupling modules.)Since there is no electrical contact at
all between the digital and analog blocks, DSI (digital signal interference) doesn't even have a chance to develop The resulting sound
is clear and lifelike, without the harshness sometimes associated with the CD format.

0 Optical and Electrical Coaxial Outputs

Users With amplifiers equipped With digital input facilities or outboard D/A converters can take their choice between two types of digital
output, Digital data transfer between CD player and amplifier provides unmatched signal integrity, Optical transfer boasts the additional
advantage of eliminating any possibility of electrical interference "looping from CD player to amplifier via the AC power supply
