©@ High Power Output
The A-G10 delivers 135 watts of clean, continuous power per channel into 8 ohms with no more than a remarkably low 0.008% total
harmonic distortion. {ts ability to drive low impedance loads is truly outstanding: dynamic power is rated at 2.x 460 watts into 2 ohms.
®@ Oversized Power Supply Block for Effortiess Drive of Low Impedance Loads
To faithfully amplify any music signal and provide the abundant power reserves required to faithfully reproduce today’s wide dynamic
range digital sources—these were the goais in the minds of the Onkyo engineers who developed the A-G10. To achieve them theyemployed
only the finest quality components in the A-G10's power supply block, the foundation on which this emplifier’s impressive perlormance
js built. Five separate windings on the secondary side of the massive main power transformer provide independent valtages for each
of the separate analog circuit blocks, The digital block of the D/A converter employs a separate power transformer. Finally, the teft and
right channel rectifier blocks feature high speed switching diodes and a total of eight high current split chemical capacitors,
@ Modular Construction Separates Principle Circuit Blocks
Each of the four principie circuit blocks of the A-G10 are isolated as far as possible from the others in order to keep electromagnetic
interference to @ minimum, The massive left and right channe! power supply blocks are located as close to the output jacks as possible
and heavily shielded. The Opto-Driven D/A converter and digital processing blocks are located in the opposite side of the chassis from
the power supply and both encased in separate copper plated, electro-magnetically shielded cases.
@ Twin 18-Bit D/A Converters with Opto-Drive*
Built-in D/A converters mean that users can route digite! output from CD and DAT players directly into the A-G10. Both optical and
electrical input jacks are provided on the rear panel for this purpose. To convert the digital input into the purest, most distortion free
music signal possible, the A-G10's dual 18-bit D/A converters are both equipped with Opto- Drive. Separate converters for the left and
tight channels eliminate phase shifting which can muddy the sound —especially in the high frequencies. 18-bit D/A conversion provides
better linearity and higher resolution than 16-bit systems: benefits which are most apparent with delicate low level signals.
© Opto-Drive’ Power Amplifier Circuitry
The A-G10 employs Onkyo’s exclusive Opto- Drive in the crucial differential amplifier stage for a music signal free of distortion caused
by electromagnetic interference.
