About Ocean Way
It all started with speakers. Ocean Way Recording began in 1968, as a showcase for
Allen’s custom monitors.
Allen needed impressive sounding material for his speakers so he began to record music
that sounded dramatic! The studio business boomed and he met the demand with many
rooms in several locations. At the peak of the studio business, Allen designed and owned
four recording studio complexes.
Five time Grammy® Award winning Allen Sides has personally recorded over 1,000
albums, many of which have become audiophile classics. He has worked with the finest
and most famous artists of the last four decades. Albums recorded in Allen’s studios have
sold over a billion copies. Allen’s hearing capabilities enables our engineers to translate
every sonic nuance, bringing a new dimension and understanding to what is possible in
high-end speaker design. His ears are our final design tool.

S12A Description
1) High Resolution HR4
The Ocean Way Audio HR4/HR4S Reference Monitor is an accurate, wide-dynamic-range, sound-delivery system for the
professional listening environment. It is 25.5” wide and features an integrated 2-way dual-horn, directivity-control loudspeaker
that can be placed as a pair in any environment to provide an exceptionally-accurate and revealing stereo monitoring
At the heart of the acoustic design is HR4’s dual/hybrid waveguide system. Its unique design was engineered utilizing 3D
modeling and then cast in a stone-like resin. This accurate process allows for the creation of geometrically-complex surfaces
that are accurately-matched for delivering detailed imaging. As a result, the HR4 delivers a stunning 100 x 40 degree
dispersion pattern over a very wide audio range. A massive horizontal “sweet-spot” is revealed with rich detail across a broad
area of the listening spectrum. The consistency of its stereo image, even at the far corners of the room, is achieved due to the
highly consistent directivity response of the speaker system. This is often a delightful surprise to the listener in light of what is
available today.
The HF driver is a high-definition silk fabric dome design with excellent mechanical linearity. The LF driver is a geometrically
reinforced aluminum cone with a vented cast-aluminum chassis yielding optimum strength and high-power linearity. Combined
with a rock-solid wood/composite cabinet, the system is tuned to perfection with an undetectable crossover transition between
the drivers. Our two-way, self-powered design delivers an unprecedented level of performance allowing for flexibility of
placement in the room with a matched uniform frequency response of 35 Hz to 25 kHz.
For those who wish to achieve even greater SPL, we offer a 3-Way version with dual 12” sub-bass cabinets – entitled HR4S.
HR4S delivers 25 Hz to 25kHz @ 118 db.
We carefully select and match each set of components getting them as close as possible to achieve our high performance
standards. Our process could easily be compared to building a fine musical instrument.

3) Inputs and Controls HR4
4) Input Selectors & Legends
The HR4 & HR4S are factory pre-set to Analog Input. Just plug in your source and start enjoying
the rich sound quality – nothing more to do!
Operation: There are four presets stored in the speaker’s memory. The four LEDs give you an indication of
which preset and input are active. To scroll through the options, make short (1/2 second or less)
successive pushes of the ‘LED selector.’ Once you have decided on a preset, make a push long enough
to see a change of state (i.e. flashing LEDs now stay solidly lit or turn off completely).
Inputs are clearly marked and are selected utilizing the momentary pushbutton labelled –
‘LED Selector’ on the right top corner of the panel. The legend printed below indicates which
Preset is active via the illuminated vertical LED display. Each short push of the button will cycle through to
the next factory preset. LED3 and LED4 will illuminate or extinguish per the legend.
Selecting Digital or Analog Inputs
Selecting Digital Inputs:
If you want to use the direct digital inputs, it’s very simple once you’ve toggled through the simple set-up.
Steps are: Using a small blunt tool (like the cotton swap stick one end removed) push and hold the LED
selector switch for a full second and LED #1 will be “OFF” and LED #2 is now “ON”. Now you’re in the
digital input mode.
AES/EBU requires the user to tell the speaker if it’s the left channel or right channel so… press the LED
selector switch for a ½ second or less until only LED #3 is blinking. Press and hold the LED selector
switch for one full second and LED #3 will be “ON” solid. The speaker is now digital left channel.
Press the LED selector switch for a ½ second or less and until LED #3 and LED #4 are blinking together.
Press and hold the LED selector switch for one full second and LED #3 and LED #4 will be “ON” solid.
The speaker is now digital right channel.
To return to the Analog input mode:
Push and hold the LED selector switch for a full second and LED #1 will be “ON” and LED #2 is “OFF”.
Now you’re back in the Analog input mode.
Selecting 2-Way or 3-Way
Selecting 2-Way or 3-Way mode:
If you own an HR4S model and wish to use the speaker in a 2-Way mode without the sub-bass S12A
speaker; Turn off the power to S12A then…
Press the LED selector switch for a ½ second or less until LED #3 and LED #4 are blinking
alternately. Press and hold the LED selector switch for one full second and LED #3 and LED #4 will
be “OFF”. The speaker is now in 2-Way mode.
Note: If you own an HR4S model; The speaker system will only allow for the Analog mode
when selected to 2-Way. Contact Ocean Way Audio support with any questions.
To return to 3-Way mode… Press the LED selector switch for a ½ second or less until LED #4 is
blinking. Press and hold the LED selector switch for one full second and LED #4 will be “ON”. The
speaker is now in 3-Way mode.
Note: If you own an HR4 model; you can add an S12A Sub-Bass at any time however the
speaker system will only allow for the Analog mode when selected to 3-Way. Contact Ocean
Way Audio support with any questions. (When 3-Way mode is selected, the low frequency output
has a 4th order L-R filter at 85Hz.)

water. Disconnect the mains power cable when cleaning to avoid risk of electric shock. Do not use alcohol
or ammonia based cleaners.
Driver active surfaces will not require cleaning as they are deep-set inside horn expansions.
5) HR4S & S12A / Physical Setup
HR4 & S12A Sub-Bass Combine
forming HR4S
(Stand not included or required)
Best practice is to physically
align the top HR4 speaker with
the Sub-Bass S12A cabinet –
as shown on left. This ensures
optimum time-alignment.
See next slide for typical
console set up.
Some consoles will not afford a safe support the HR4, and we generally recommend using the Sound Anchor ADJ2 for
this. The HR4 is easily positioned on the ADJ2 platform and can be rotated safely as its center of gravity falls well within
the platform’s generous footprint. In most cases, the stand’s base will probably need to be positioned parallel to the
console’s “legs” and the HR4 rotated to best horizontal aim. More on this follows.
Achieving wideband stereo sound is deceptively simple; you must be able to hear the full range of two speakers. The HR4
represents a breakthrough in modern stereo studio monitor technology. It employs advanced, full-spectrum directivitycontrol as compared to the typical compact direct-radiator monitor which exhibits narrow HF “beaming”. While most
compact monitors establish a “sweet spot” between them, the HR4 establishes a wide-area Stereo-Zone™ in a wide area.
The HR4 can easily be aimed to establish a truly accurate Stereo-Zone™ for multi-person listening. For example, we have
plotted, below, the 100 degree horizontal pattern of the HR4 in an overhead plan-view with a typical console. Speaker
centers are about 72” apart. You can see where the individual HR4 sound-fields overlap; this defines a wide area where you
can hear full-band stereophonic sound. In this case, we chose an inward aiming of 20 degrees. If the pair were aimed more
inward, the stereo-zone narrows. Aiming more outward, the Stereo-Zone™ widens but the result is more sound impacting
the sides of the studio environment, changing the overall sound of the space. It is up to the HR4 owner or studio designer to
choose what works best. Often this is a matter of listening and achieving the most acceptable aesthetic sound (always our
first recommendation). A 20 degree inward aiming angle is a good place to start, nice wide field at the console and also for
anyone behind or off to the sides (two or three persons can work at once on a mix and hear the full stereo sound): Below is a
graphical depiction showing (below right) the location of the stereo zone in yellow, which is simply the mutual overlap zone
of the two HR4’s.
The HF horizontal pattern of the HR4 (S) is largely controlled by the HF horn walls. There is a very easy onsite test for aiming: If you can see the little “dot” or circle at the entrance to both HF horns, you will be in the
stereo-zone. You can set up your HR4’s this way by just visual inspection. Below is a depiction of a location at
the fringe of the stereo zone:
HR4 & HR4S are perfect for any teaching environment. Its 100 degree dispersion pattern allows everyone to hear
the full stereo mix in great detail. Below, an almost zero-aiming-angle achieves a wide Stereo-Zone for a classroom.
6) Signal Flow 2-Way & 3-Way
The HR4 is configured as a 2-way system with no programmed roll-off in the low end response. There is a
factory preset installed that will allow the speaker’s low frequency response to be extended by adding a subbass cabinet. Ocean Way Audio offers the S12A subwoofer which has been matched to create a balanced
system response.
Select Preset 2 - LED3 off/LED4 on to make the 3-way preset active when choosing this option.
7) S12A Description
< Caution!
Do Not Press and Hold Select Button!
Loss of Factory Programing could occur.
Only a quick tap of the "Select" toggle
switch is required to change Presets.
Applies to HR4S 3-way systems and can be added to
an HR4 2-way system if desired. The S12A sub-bass
cabinet is a single 12” long throw woofer in a bass
reflex cabinet extending the response down to 25Hz. It
is powered by an 800 watt amplifier.
The sub-bass is factory programed to Preset #2. The
sub-bass can be decreased 1db by selecting Preset
#1. The sub-bass can be increased by 1db by
selecting Preset #3 and an additional 1db by selecting
Preset #4.
The Voltage is set internally
by the factory. Not user
selectable from panel
The “Select” button is a momentary toggle switch.
