RADIO and TELEVISION INTERFERENCE
The equipment described in this manual generates and uses radio-frequency energy. If it is not
installed and used properly-- that is, in strict accordance with our instructions - it may cause
interference with radio and television reception.
This equipment has been tested and complies with the limits for a Class A computing device in
accordance with the specifications in Subpart J of Part 15 of the FCC rules. These rules are designed
to provide reasonable protection against such interference in a residential installation. However,
there is no guarantee that the interference will not occur in a particular installation, especially if
a "rabbit ear" television antenna is used.
If the Emax II does cause interference to radio or television reception, you can try to correct the
interference by using one or more of the following measures:
■Turn the television or radio antenna until the interference stops.
■Move the Emax II to one side or the other of the television or radio.
■Move the Emax II farther away from the television or radio.
■Plug the Emax II into an outlet on a different circuit than the television or radio.
■Consider installing a rooftop antenna with a coaxial lead-in between the antenna and
television set.
7. This product, in combination with an amplifier and headphones and speakers, may be capable
of producing sound levels that could cause permanant hearing loss. Do not operate for a long
period of time at a high volume level or at a level that is uncomfortable. If you experience any
hearing loss or ringing in the ears, consult an audiologist.
8. This Emax II may be equipped with a polarized line plug (one blade wider that the other). This
is a safety feature. If you are unable to insert this plug into the outlet, do not defeat the safety
purpose of the plug. Contact an electrician to replace your obsolete outlet.
9. The power supply cord of the Emax II should be unplugged from the outlet when left unused
for a long period of time.

WHAT’S AN EMAX II?
Emax II is a responsive, low cost, surprisingly easy-to-use musical instrument with
staggering creative possibilities. It’s also a composer’s personal orchestra, a recording
studio’s chance to have hundreds of acoustic and electronic instruments “on call” at any
one time, a university’s research tool...but most of all, it provides the means for some
truly special musical experiences. To give you a better idea of its capabilities, here are
just a few of Emax II’s highlights:
In addition to synthesizing sounds, Emax II digitally records (“samples”) real-world
sounds into its memory with 16-bit, CD quality in either mono or stereo (optional). If you
want Emax to sound like a piano, sample a piano; if you want it to sound like a barking
dog, sample a dog. Pre-sampled sounds can also be loaded into Emax II’s memory from
disks. Emax II also contains Spectrum Synthesis, a powerful additive synthesizer.
These sounds may then be modified with Emax II’s synthesizer processors and/or state-
of-the-art digital processors. The synthesizer-type processors include:
●Dynamic digital lowpass filters (VCF) with AHDSR envelope generators
●Digital amplifiers (VCA) with AHDSR envelope generators
●LFOs with adjustable rate, delay, and speed variation
●Two programmable wheels for real-time control over pitch, filter cutoff, AHDSR
attack rate, level, LFO modulation index, etc.
●Two programmable footswitches for real-time control over sustain, release,
sustenuto, “patch” change, and sequencer start/stop
● Velocity sensitive keyboard, where keyboard dynamics can control any or
all of the following: VCA level, VCA attack, VCF cutoff, VCF attack, and VCF Q.
The keyboard can play up to sixteen notes simultaneously; however, Emax II can chorus
its voices or play in stereo with no loss of polyphony! Note that like standard analog
synthesizers, there is a complete set of modifiers for each note. Therefore, when we refer
to the “filter”, "LFO" or “VCA," we are really talking about sixteen filters, LFOs and
VCAs.
Digital processing techniques include:
●Truncation (shortening the beginning and/or the end of the sample)
● Looping the sample (or any portion thereof)
● “Crossfade” looping for smooth, clean loops
●Digitally combining (mixing) two samples
●Sound reversal, as well as sample rate conversion and pitch conversion
●Transform Multiplication™, a powerful new DSP effect
●Splicing two or more samples together (imagine a piano that turns into a voice, that
turns into a seagull...)
●Advanced split capabilities and the ability to layer four presets on a single key
●Easy doubling, plus velocity-controlled crossfading and switching between
samples
●Individual tuning and attenuation for each sample
●Ultra-flexible, programmable arpeggiation
●16 track “scratchpad” sequencer

Instant Gratification
Sounds can be stored on Emax II’s built-in hard disk drive, on an external hard disk
drive, or on commonly available double-sided, double-density (DSDD) 3.5 inch floppy
diskettes (as used with many personal computers). Thanks to sophisticated disk
managementtechniques, it’s easy to save, organize, retrieve, rename and catalog various
sounds. Perhaps best of all, Emax II is fully compatable with Emax I disks, allowing
access to the huge Emax I library already in existence.
For outside world interfacing, the built-in sequencer can sync up to a 24, 48, or 96 pulses-
per-quarter note clock or MIDI sync; there’s also a complete complement of MIDI
functions.
Despite all this flexibility Emax II is nonetheless not that hard to learn...as you will see
during the course of this manual.
SEND IN YOUR WARRANTY CARD NOW!
It is vital that you send in your warranty card so that we can notify you of enhancements,
new features, and software bugs (nobody’s perfect) and cures. Don’t miss out: Send it
in now!
INSTANT GRATIFICATION!
If you just can’t wait another second before hearing the Emax II, we understand. Follow
the directions below EXACTLY as given and get ready to hear some great sounds.
(Incidentally, in case you make a mistake or run into problems, don’t worry. This process
is described in greater detail later.)
1. With the Emax II unplugged, patch the rear panel Right & Left, or Right Mono jack to
the input of a high quality amplification system. You can also plug stereo headphones
directly into the headphone jack.
2. Check that the rear panel voltage selector is set for the correct voltage in your part of
the world.
3. Plug the Emax II line cord into an AC outlet.
4. Check that no disk is currently in the drive. If so, or if the disk drive contains cardboard
packing materials, push in on the disk eject button towards the bottom of the drive,
remove the disks or packing materials, and put them in a safe place.
5. Turn on power; Emax II will do a drive check for a few seconds, then the display will
say “Please Insert Disk” if you do not have a hard disk or “Checking SCSI 1, then Booting
from SCSI 1” if you do have a built-in hard disk.
If you don’t have a hard disk, insert one of the diskettes that came with your Emax II into
the disk drive. The Emax II will begin loading software from the disk you have placed
in the drive.

SELECT DRIVE
6. Press the button labeled DRIVE SELECT on the front panel of Emax II. Use the data
slider to select "SCSI 0: Floppy", if you want to load a floppy disk; or "SCSI 1 Conner",
if you have a built-in hard disk drive. Then, press ENTER.
LOAD FROM FLOPPY DISK
7a. Press the LOAD BANK button, then simply insert a floppy disk and press ENTER.
LOAD FROM HARD DISK
7b. Press the LOAD BANK button, then select one of the sound banks using the data
slider. When you find one that strikes your fancy, press ENTER.
8. Raise the volume slider to the up position.
9. The display will show the name of the Current Preset (we’ll talk more about the
Current Preset concept later). Turn up the volume control and start playing the
keyboard. All right!! The display will show you the ID number (P followed by two digits)
and name of the sound you are playing. These sounds are called presets, for reasons
which will become clear later.
10. Use the telephone-type numeric keypad underneath the display to call up different
presets. Press a two-digit number; start with 01 and play the keyboard for awhile, then
press 02 and play, 03, 04, etc. At some point you will run out of factory presets, and the
display will say “Empty Preset.”
If you want, vary the control wheels towards the left hand side of the keyboard. They
may not be active with some presets, as they perform different functions with different
presets.
To load another floppy disk, press LOAD BANK,and the display will say:
Load All Presets
And Sequences
Insert another floppy disk, then press ENTER. Emax II will begin loading the new bank.
Note: Some Emax II banks require two or more floppy diskettes. In this case, simply
insert the diskettes in sequential order (1, 2, 3...).
To try out presets from other factory hard disk banks, locate the LOAD BANK button
(in the group of four buttons to the right of the numeric keypad) and press it. Use the data
slider to scroll through the available hard disk banks. When you find a bank that
interests you, press the flashing ENTER button right below it. The disk drive will start
making noises, and a few seconds later you will have loaded another bunch of sounds
into the Emax II.

CONNECTION TO A MIXER
■STEREO:Emax II has provisions for a variety of output connection schemes. The most
common hookup will probably be for stereo operation. Once you have heard the Emax
II in stereo, you will never be satisfied with mono again. Connect the left and right audio
out phone jacks to the inputs of your mixer or stereo preamp. Emax II will also drive
stereo headphones, which can be plugged directly into the headphone output. For
maximum dynamic range, keep the front panel volume control turned up full.
■ MONO: If a monophonic amplifier is used, simply connect the right/mono output to
the input of the amplifier. Guitar amps are not recommended because they are generally
noisy and low fidelity. The output level of the Emax II is somewhere between instrument
and line level. Care should be taken when connecting to an instument amplifier so that
the delicate nerve cells in your ears are not damaged.
■ SUBMIX OUTPUTS: There may be times when different equalization or reverb
settings are desired on the various instruments that have been sampled. Emax II has
eight polyphonic outputs that can be used when individual processing on specific
instruments is desired. Any combination of voices can be programmed to appear at any
channel output. Voices are assigned to output channels using the Edit Assignment
function in the Preset Definition module or in the Keyboard Mode function of the
Dynamic Processing module. Each of the Sub A, Sub B, and Sub C outputs on Emax II
are stereo jacks. The tip of each jack (accessed when a standard phone plug is inserted)
connects to the right or left output of the group. If a stereo plug is inserted, the Ring of
the stereo plug serves as a signal return, which sums into the Main outputs.
Therefore, the Sub A, B, C jacks can serve as effect sends and returns in order to further
process selected voices and then return them to the main mix.
The submix send/return jacks can be used to process selected voices and return them to
the main mix instead of using the effects bus on your mixing board. In a pinch, the effects
returns could also be used to sum additional instruments into the main outputs of the
Emax II.

SAMPLE IN CONNECTION
The Sample In jack can accept any signal level from microphone level to line level. The
gain is adjusted with the data slider while in VU/gain mode in the sample module. The
level can be read in the liquid crystal display while in this mode.
If your Emax II contains the stereo sampling option, use a stereo plug in the Sample In
jack to sample in stereo. The Tip of the stereo plug corresponds to the Left channel and
the Ring of the plug corresponds to the Right channel.
MIDI CONNECTION
Emax II provides a MIDI In and a MIDI Out/Thru port.
■ The MIDI In port on the Emax II is connected to the MIDI Out port of an external MIDI
controller which could be a keyboard, a sequencer, MIDI drum kit or whatever. Note that
the Emax II can only respond to information that your controller transmits. Therefore,
if your MIDI keyboard does not have velocity and pressure sensitivity, Emax II will not
respond to velocity and pressure.
■ MIDI Out can be connected to another MIDI instrument or sequencer. In MIDI Thru
mode, MIDI Out will re-transmit any MIDI information that appears at the MIDI In port.
In MIDI Out mode, only information from the Emax II’s keyboard, sequencer or realtime
controls will be transmitted, except when overflow mode is selected. Overflow mode
allows a second Emax II to be connected to the MIDI Out to allow 32 channel operation.
Use cords that have been designed specifically for MIDI. While regular 5 pin DIN
cords may work, they are not shielded correctly for MIDI use and may cause ground
loops between equipment.
FOOTSWITCH AND PEDAL CONNECTION
■ Two control footswitch jacks are provided for performance control of sequencer,
arpeggiator, sustain, release, X-switch, and preset advance. The footswitches need not
be connected for the unit to operate but they offer exciting control possibilities. The
footswitches should be of the momentary contact type, but can be either normally-open
or normally-closed.
■The control pedal is used as a realtime control in the same manner as the wheels. It can
be programmably routed to a destination by using the realtime control section of the
preset definition module. The pedal can either be a voltage type, (which outputs a DC
voltage from 0-9 volts at the tip of the jack) or a resistance type (which varies a 10K ohm
resistance from the tip to ground of the jack). Both the footswitches and the pedal are
available from your dealer.
CLOCK IN CONNECTION
The Clock In jack allows a non-MIDI external device such as a drum machine or
sequencer to control the tempo of the sequencer or arpeggiator. Emax II can receive input
clock rates of 24, 48, or 96 pulses-per-quarter note. The pulses should be at least 1
millisecond wide and have a level of 1 to 5 volts.

Connections
CLOCK OUT CONNECTION
The Clock Out jack allows the Emax II to be the master clock and drive non-MIDI
sequencers and drum machines at a rate of 24 pulses-per-quarter note. This is a 5 volt
pulse which is about 6 milliseconds wide.
SCSI CONNECTION
The 25-pin connector on the rear of your Emax II is a SCSI port (pronounced scuzzy),
which stands for Small Computer Systems Interface. SCSI is an ultra high-speed parallel
port, normally used to connect external hard disk drives. Up to 7 external devices can
be connected the the SCSI port. Each device on the SCSI bus must have its own unique
ID number so that Emax II can distinguish it from the other devices. If you have an
internal hard disk, it will be assigned ID #1. The floppy drive is assigned ID #0. If there
are two devices on the SCSI bus with the same ID number, a SCSI error will result.
Consult the operation manual of your external storage device for information on
changing the ID number.
●Always use quality SCSI cables which are as short as practical (total length <12 ft).
● Tighten the thumbscrews on the jacks to ensure good electrical connection.
● Power up external SCSI devices before the Emax II.
● All SCSI devices on the bus must be turned on.
RS-422 CONNECTION
The RS-422 connector is a high-speed serial communication port which allows data to be
transferred to and from an external computer at a high rate (500K baud). The connection
cable to the external computer will generally be supplied with a software package (such
as Sound Designer by Digidesign) and will not usually be available from your music
dealer.
110V/220 V SELECTOR
The 110V/220V selector allows the Emax II to be used in either 110 volt or 220 volt
environments at either 50 Hz or 60 Hz. In the USA ,110 volts is the standard. To change
the voltage setting, first UNPLUG the unit; then use a flat blade screwdriver to change
the setting. WARNING: Operating Emax II at the wrong setting may seriously damage
the unit.
AC POWER CONNECTION and FUSE
The AC power connector is how the Emax II gets power (obviously). The fuse receptacle
is not as obvious. It is located directly over the power receptacle. Before changing or
checking a fuse, UNPLUG the power cord. To remove the fuse holder, squeeze the two
tabs located on either side of the fuse holder together. The fuse holder will now pop out
with it’s two fuses. The Emax II uses (2) 1 amp, 250 volt fast-blo mini-fuses. The Emax
II should not normally blow fuses. If a fuse that has been replaced blows again, do not
attempt another replacement. Have the unit serviced!
■ Warning: All SCSI
devices connected to
the SCSI bus must be
turnedon,orEmaxIIwill
not boot.
