The joy of par balance amplification.

The operational principle of the electrostatic condenser type is based on a
system whereby plus and minus output signals are input by push-pull into
two electrodes sandwiching a diaphragm with a high level otaccuracy and
equidistantly. resulting in the vibration ol'an ultra-thin membrane through
the repulsive force and suction force of static electricity. which is then
converted into sound. The balance method. which is considered to be the
ideal for amplification. is thus extended to speakers. The electrostatic
system entails input by balance. output by balance. and sound conversion
by balance. and. in realizing all these features. constitutes the perfect

balance system. It is the only system that makes it possible to listen to
sound in the ideal manner permitted by the balance system.

The new SRM-007tll is our flagship model of
a driver unit intended exclusively for
earspeakers characterized by their \siderange.
high dynamic range and outstanding
operating features with full allowance made
for SACD and other new-generation highs
density formats. 'lhe ultra-light polymer film.
only a few microns thick. realizes
unprecedented response and a high degree of
resolution. Since it is driven on all sides. there
is almost no partitioned vibration and there is
no phase distortion. Nor is there any
imbalance in the sound quality of the unit or
distortion caused by the network.
Electromagnetic distortion also does not
occur. It opens up the world of high sound
quality that is the mark of headphone
listening. :1 world characterived by the
absence of need for large output. the high
degree of freedom pemtittcd by the use of
high sound quality elements for use with
small signals. and the even balance between
left and right unaffected by acoustic
conditions in the listening room.

- improved circuit. higher grade of reproducibility for
SACD and other new-generation audio formats

- Pure balance amplifier in which the XUt balance input
does not have to pass through a transformer. an
inversion amplifier, etc

~ Simple twostage amplification structure based on
hand selected low-noise PET. Load resistance consists of
nomlnductive coil resistance manufactured by Dale. thus
delivering straightforward properties that take
advantage of the features of vacuum tubes and
outstanding sound quality with a high level of clarity.

- Output stage is designed to lower impedance by using
a hand selected high voltage dual triode l6FQ7 type) in
parallel connection. which has resulted in an
impmvement in dynamic range especially in the high
frequency.

SR-007

- the heater power source for the vacuum tube uses a
power circuit of the DC ignition type using an electrolytic
condenser and a highopecd Schottky barrier diode.
further improving the SN ratio.

- Large-capacity power transformer and condenser.

- Equipped with one XLR (balanced) input and two RCA
(unbalanced) input systems. total of three input systems.

SR- 404 HF SR- 303 F SR- 202

- RCA inputs. switching with earth side ensures that there
is almost no interference between devices.

- The RCA terminal 'lnput 1' is equipped with parallel
output terminals and enables input throughout.
Connection with other pro-amplifiers and recording
decks, etc. is also possible.
