Congratulations on your purchase of the SYN-2 preamp. The SYN2 is the culmination of many years refining and fine tuning our
modular preamp concept. Please familiarize yourself with the many
possibilities to get the best performance out of your preamp.
The SYN-2 can be used in three primary applications:
1) The SYN-2 can be used to add channels to an existing head or combo
• Your amp MUST have a series effects loop
• It will NOT work with certain loops. See details later in this manual.
2) Straight to front of house or monitor
• In a live setting you can use the cab simulated DI output to go straight to your board or
active monitor.
3) Recording
• Use the DI output to connect to an external mic preamp and then directly to your
software.
• The cabinet simulation can be bypassed if you wish to use your own IRs.
Quick connection guide:
Option 1) To use the SYN-2 as a standalone preamp to record directly into your computer or direct
to a PA live, simply use the balanced XLR DI output to send the signal to the desired location.
Option 2) To use the SYN-2 in a “normal” live rig using guitar type speakers, connect the MAIN out
to the input of your power amp/speaker combination or into a powered speaker specifically voiced
for guitar. Alternately, you can connect the MAIN out into the effects return of most amps and use
the head or combo as just a power amp and the SYN-2 becomes the preamp.
Option 3) This is the coolest thing the SYN-2 can do. With this setup, you can actually use the SYN-2
to add the module as another channel to your amp and footswitch between the channels in your
amp and the SYN1.
These different methods will be explained in detail later in this manual. Please read the entire
manual to get a true understanding of all the possibilities.
SPECIFICATIONS: POWER CONSUMPTION: 40 WATTS 50/60Hz
FUSE:
T500mA/250V @ 110-118VAC 50/60Hz - NORTH AMERICA
T250mA/250V @ 220-240VAC 50/60Hz - EUROPE
TUBES: ONE 12AX7
FRONT PANEL
REPLACING MODULES: When inserting or removing modules, simply turn both thumbscrews to the left until
they fall loose. Do not remove the screw completely. Remove the module by pulling out on the
thumbscrews. Slide in a new module, and push in on the center knobs until flush with the front panel.
Tighten the thumbscrews, by turning to the right until snug. The thumbscrews must be snug for proper
module grounding. You don’t need to “crank” them down but do not leave them loose.
It is HIGHLY recommended that you turn the SYN-2 OFF before swapping modules. If however you "hot
swap" a module, you may find that at times the switching logic may not work correctly. To re-set this,
simply turn the SYN-2 OFF and then back ON after one second.
1. INPUT JACK - Connects directly to your instrument
2. CH./STORE - Selects the desired channel on your module. This momentary push button will sequentially
step through the module channels. Each time the button is pressed and released, the SYN-2 will step to
the next channel. This is also used in MIDI programming - described later in the manual.
3. SAG - Under license from Steven Fryette Designs, the SAG knob mimics the voltage sag of a tube
amplifier. This effect is subtle and is really a “feel” thing. It is recommended that you adjust the knob to
level where the LED just comes on with heavy guitar pick attack.
4. VOLUME - Depending on how the SYN-2 is connected, this knob either controls the overall volume of the
SYN-2 or the level of the main output.
IMPORTANT - When using the SYN-2 to add channels to your head or combo, the
VOLUME control will not be active. In this scheme, the VOLUME will adjust the
level of your MAIN OUTPUT ONLY.
REAR PANEL
1. AC MAINS INPUT – Connect to a grounded outlet in accordance with the voltage and frequency
specified on the rear panel of your amplifier.
Use only the factory supplied cord or a UL approved equivalent type.
2. MAINS FUSE – The Mains fuse is located in the pull out tray at the bottom of the AC jack. This fuse
protects the unit from serious damage in case of electrical faults
3.
Warning! Replace only with same fuse type and rating.
4. AC power switch turns the SYN-2 on or off.
5. GROUND LIFT SWITCH - This switch is used to eliminate ground loops that can occur when different
earth grounded pieces of audio equipment are interconnected. Simply set the switch for the least
amount of hum. If you do not hear any difference, leave the switch in the left position.
6. PHANTOM POWER IN - Used to power a foot controller that is connected to the MIDI IN jack.
Connecting an external power supply (or wall wart) to this input will automatically send the power
back out to pins 6 & 7 of the MIDI IN jack. Use a 7 pin MIDI cable to send the power through the MIDI
cable alleviating the need to remotely power your pedal.
7. DI OUTPUTS - Balanced XLR outputs used to send your SYN-2 tone straight to the mixing board or
active cabinet
XLR LEVEL - A level switch for the XLR outputs. Use the setting that best matches your mixer.
GROUND LIFT - Lifts ground to prevent ground loops. Set for the lowest hum level.
CAB SIM BYPASS - Removes the cabinet simulation circuitry to become a balanced, full range
output.
8. MAIN OUTS - Left and right full range outputs to connect to external devices such as power amps, FX,
etc. Note: These are not speaker emulated outputs.
9. FX SEND JACK- This output connects to the input of your effects unit. Use a shielded cable.
10. FX RETURN JACKS - Connect the output(s) of your effects unit using shielded cables.
11. EFFECTS LOOP LEVEL SWITCH - Selects between line level and pedal level of the effects loop. Use the
setting that sounds best and does not cause excessive noise or distortion/loss of volume.
12. FROM AMP EFFECTS SEND and TO EFFECTS RETURN jacks - Used when using the SYN-2 to add
channels to and existing amp. This is explained later in the manual.
13. MIDI IN - Input from the SYNERGY 5F foot controller (sold separately), or any external MIDI switching
system.
14. MIDI THRU - MIDI messages/data that is received at the MIDI IN connector is passed through to the
MIDI THRU jack for “looping” to other MIDI controlled units (such as additional SYN-2 units)
15. MIDI CHANNEL-OMNI/SELECT – Used to set up communications with external controllers. See the
MIDI section later in this manual for details.
16. INST IN - Same as the input on your front panel and usually used in a rack set up.
Note - When using the input on the front panel, the "INST IN" is disengaged.
CONNECTING SYN-2 TO YOUR HEAD OR COMBO
The SYN-2 can be used to ADD channels to your existing head or combo. You will need three high quality,
shielded instrument cables in addition to your guitar cable.
1) Connect your guitar to the front or rear INPUT of the SYN-2. These inputs are functionally the same except
the front input overrides the rear.
2) Connect an instrument cable from "TO AMP IN" on the rear of the SYN-2 to the INPUT of your amplifier.
3) Connect an instrument cable from "FROM AMP FX SEND" to the FX LOOP SEND of your amplifier
4) Connect an instrument cable from "TO AMP FX RETURN" to the FX LOOP RETURN of your amplifier
5) The LEVEL switch between the "FROM AMP FX SEND" and "TO AMP FX RETURN" jacks is used to set the
level of the SYN-2 to help match your effects loop. Because there can widely varying levels between
different effects loops, a little bit of experimentation may be needed to find the optimum setting for this
switch.
There are some special requirements and/or caveats when using the SYN to add channels to your amp.
The loop on your amp MUST be a 100% series loop. The SYN1 will not work in a parallel loop. If in doubt,
consult the manufacturer of your amp to determine this. One known issue is with the Mesa Dual and Triple
Rectifier, Road King and Roadster amps that prevents the SYN1 from working properly in the loop. By design,
the Boogie loops always have a small amount of dry signal mixed in with the loop which will wreak havoc
with many effects and also the SYN1. There may be other amps that we are not aware of with loops that are
not compatible. We will make this information available as we discover these issues.
CONNECTING SYN-2 TO RACK MOUNT POWER AMP
•
Use the MAIN L (left) and R (right) outputs to connect to rack mount power amps
________________________________________________
CONNECTING SYN-2 TO ACTIVE MONITORS/MAIN PA
•
Use the MAIN L (left) and R (right) DI outputs to connect to your mixer or active monitors. When
using external cab simulation devices (think IR loaders), you can defeat the cabinet simulation
circuitry using the BYPASS switch.
MIDI
The SYN2 is compatible with most MIDI controllers on the market. You can set up 128 different presets, each
of which can recall a different channel on the preamp.
Connections
MIDI IN – This is where you connect your MIDI controller or Synergy 5 button pedal. The connector is 7 pin,
but it can also accept a standard 5 pin MIDI cable. 7 pin cables are only used with MIDI devices that accept
phantom power over pins 6 and 7. If your MIDI device has a 5-pin MIDI connector, it doesn’t accept
phantom power and must be powered with its own power supply.
PHANTOM POWER IN - Used to power a foot controller that is connected to the MIDI IN jack. Connecting an
external power supply (or wall wart) to this input will automatically send the power back out to pins 6 & 7 of
the MIDI IN jack. Use a 7 pin MIDI cable to send the power through the MIDI cable alleviating the need to
remotely power your pedal.
MIDI THRU – If you have additional MIDI devices (such as additional SYN-2 units) in your system, you can
connect them here. Commands from your MIDI controller will be passed through this port to the next
device, allowing your controller to control multiple devices simultaneously.
Setup – The 16 position rotary miniature rotary switch selects the MIDI channel to communicate with your
controller. Use a small screwdriver to set to the desired channel. The slide switch selects OMNI or SELECT
modes. Set the slide switch to SELECT to activate the rotary MIDI CHANNEL switch. OMNI is an alternate
mode that allows the SYN-2 to receive commands on all 16 channels simultaneously.
Programming
To program the SYN2 to respond to your MIDI controller, do the following:
1. Make sure your MIDI controller is connected to the SYN2’s MIDI input jack
2. Select a preset on the MIDI controller
3. Using the channel select button on the SYN2, select the module channel (or bypass) you wish to have
come on when the preset is selected using the SYN-2 front panel SELECT pushbutton.
4. Hold the channel select button until the bypass LED flashes. This should take about 3 seconds.
Repeat steps 2 through 4 above for each controller preset you wish to store. The next time you select one of
the programmed presets, the SYN_2 will automatically switch to the desired channel.
Please note: If the bypass LED doesn’t flash after holding the channel select button for a few seconds, the
amp is likely not receiving MIDI commands and the setting will not be stored. Check your MIDI controller and
its connection to your amp. Also make sure that the MIDI controller is set to the same MIDI channel as the
SYN-2.
Continuous Controllers
The SYN2 also responds to MIDI continuous controller (CC) messages. These MIDI messages are typically
used for “instant access” buttons on more advanced MIDI controllers – buttons that can be set up to directly
select amp channels. When using CC messages, you don’t need to go through the programming process
described above.
CC Number
Function
56
Select channel 1A
57
Select channel 1B
58
Select channel 2A
59
Select channel 2B
60
Bypass
64
Mute
When selecting a channel using CC messages, only a message with a CC value of 64 or higher will have any
effect. Messages with a CC value of 63 or lower is ignored. The Mute CC (#64) will mute all channels of the
SYN-2 if a value of 64 or higher is received, and will unmute the amp if a value of 63 or lower is received.
Connecting Multiple SYN2s
Follow the steps below to combine 2 or more SYN2 units. In this connection scheme the first SYN2 in the
signal chain is called the “Master” and the second SYN2 is the called the “Slave”.
- Connect your instrument to the Input of the Master unit.
- Run a cable from the "TO AMP IN" of the Master unit to the "INST. IN" on the rear panel of the Slave unit.
- Connect the main output L/MONO of the Slave unit to the "FROM AMP FX SEND" of the Master unit.
- Use the MAIN OUT(s) or the DI output(s) of the MASTER unit to connect to your power amp / monitors.
- Program the Slave with the Master in Bypass Mode.
Note - When using the input on the front panel, the "INST IN" on the back panel is disengaged.
The same procedure is recommended for adding a third, fourth etc. unit to the system
For most systems, it’s recommended that you set your SYN2s to the same MIDI channel. You can follow the
programming instructions above, repeating the steps for each SYN2. When you want to access the second
SYN2, make sure that the first SYN2 is set to bypass.
USING THE SYNERGY 5F PEDAL
The pedal is essentially a 5 button MIDI pedal that is preset to send program change commands 1 through 5
on MIDI channel 1. Your SYN2 will come preprogrammed to respond to modules channels 1 through 4 on
buttons 1 through 4. Button 5 will be assigned to BYPASS. You can change/assign any module channel to
bypass to be on any buttons you wish by following the steps under PROGRAMMING above. The 5F pedal can
operate from any power supply that puts out 9 to 12 volts AC or DC and has a current rating of at least 50
milliamps.
