M-505
Complete DC Power Amplifier
High technologyfeatures
allow this completeDC power amp to deliver
the cleanestpossiblepower. It has dual line construction,four newly
developed l8,000prF capacitors, extra large power transformers,
protectioncircuitsand a low filter switch.

Continuouspower output is I l0 watts per channel,min. RMS, both
channels
driven into 8 ohms at I kHz. with no more than 0.0590THD.
P-303
Ultimate Stereophonic Preamplifier
Sophisticated
electroniccircuitry in the P-303 solvesall your preamp
problems.Dual line constructioneliminatestransientdistortion. Reed
relaytransientkiller circuitry cuts out annoying 'clicks' and 'pops'. Bus
feeders
and bus ground linesbring impedance
down to near zero, thus
virtually eliminatingdynamic distortion. There's a high performance
headamp for MC cartridges,too, with improved 70dB S/N ratio.
RIAA equalizationis +0.2d8,2OHz to 20kHz.

M-9000
The Power Amp For Any Need
All stagesof the signal path, even the power supply, are completely
separatedinto left and right mono amplifiers. This design effectively
reducesdynamic modulation and significantly improves stereosepara-
tion. Multi-purpose LED peak meters and large easy-to-readpower
metersassurepreciseyet simple operation. Large heat sinks and relay-
type protectivecircuits protect it from overheatingand circuit malfunc-
tions. Continuous power output is 55 wats per channel into 8 ohms at
lkHz, 0.190THD.
P-gm0
The Preamplifier lryith Everything
The P-8000 represents
one of the new generationof high grade stereo
preamplifiers.
An impressive
array of controls, including bassand tre-
ble defeatswitches
and both high and low filters, allows you ro ger e\-
actly the soundyou want. There'salsoa convenient

u-30
Peak Meler & Selector Unil
For line levelvoltageand power amp wattageoutput measuring,
Onkyo
givesyou the U-30 peak meterand selector
unit. The U-30 is designed
to
switch several
turntables,tuners,tapedecks,power amps and speakers
in and out of the system.The power metersare logarithmicallycom-
pressedand have an extremely fast lOGmicrosecond attach time for a
OdB reading. Frequencyresponse linear within +ldB from 20Hz to
is
2OkHz.
E-30
Octave Band Stereo Equalizer
This highly advancedoctave band equalizeris designedfor usewith the
P-303 preamp or in a top grade audio system to tailor frequency
response taste.Up to lOdB attenuation or boosting is possibleat nine
to
frequency poins spaced at l-octave intervals. Boost,/attenuation is
separablefor two stereochannelsand the lowest center frequencycan
be switched to either 63H2, 45Hz or 32H2. Total boost/attenuation
range switching to 5dB for precisefine adjustment is also possible.
