Lex Rotary user manual REV C
Each of our Strymon digital effect pedals (excludes OB.1) have the ability to be used with mono or stereo connections. Here are 3 different connection setups you can use with these pedals.
Mono Input => Mono Output
For Mono input and Mono output on our small 2 footswitch pedals, just use a standard mono TS instrument cable into the INPUT and connect a mono TS instrument cable to the LEFT OUTPUT of the pedal.
For the TimeLine, BigSky, and Mobius, connect a mono TS instrument cable into the LEFT INPUT and LEFT OUTPUT for a mono connection. Make sure the switch on the back of the pedal is set to STEREO IN/OUT.
Mono Input => Stereo Output
For Mono input and Stereo output on our small 2 footswitch pedals, just use a standard mono TS instrument cable into the INPUT and connect a mono TS instrument cable to both the LEFT and RIGHT OUTPUTS of the pedal.
For the TimeLine, BigSky, and Mobius, connect a mono TS instrument cable into the LEFT INPUT and both LEFT and RIGHT OUTPUTS for stereo output. Make sure the switch on the back of the pedal is set to STEREO IN/OUT.
Stereo Input => Stereo Output
For Stereo input and Stereo output on our small 2 footswitch pedals, you must first open up the pedal to move the internal jumper over the LEFT 2 pins to set the pedal for TRS Stereo input. Please see the following FAQ for further information on this setup:
Once the pedal is set for TRS Stereo input, make sure to use a TRS Stereo cable into the INPUT and connect a mono TS instrument cable to both the LEFT and RIGHT OUTPUTS of the pedal.
For the TimeLine, BigSky, and Mobius, connect a mono TS instrument cable into the LEFT and RIGHT INPUTS along with both LEFT and RIGHT OUTPUTS for stereo input and output. On the TimeLine and Mobius, make sure that the switch on the back of the pedal is set to STEREO IN/OUT.
***Please note that Stereo Input and Mono Output is NOT available on our pedals as they will NOT sum to mono when there is a connection to the RIGHT INPUT or RIGHT OUTPUT.
We know that there are some out there that want to emulate David Gilmour’s unique Leslie sound, in which he ran his signal to both a rotary speaker and a regular guitar amp. You might be wondering why we did not add a Mix control to our Lex Rotary pedal. Wouldn’t this allow you to achieve the sound David achieved with his setup? Actually, the answer is no.
The problem is that there’s a big difference between running two physical amps (one dry and one ‘Leslie’d’) versus blending a dry signal with a Leslie signal electronically and running the summed signal through one amp. The electronically summed signal will have interferences that don’t happen with two physical amps.
A simple example is to send the same signal to two amps, but one is out of phase with the other. It may sound funny and make you feel dizzy, but you will still certainly hear something. If you combine two out-of-phase signal electronically and send it to one amplifier—you will hear nothing at all! So we don’t feel a wet/dry Mix or blend control would lead to a satisfying experience in this case. You’re actually better off with two separate amps and a Y-cable if you’d like to achieve this sound.
We have tested the Moog EP-2, Roland EV-5, Mission Engineering EP-1, and they will all work with our pedals to varying degrees. (There may be others but we haven’t tested them yet.)
We recommend using expression pedals that have a minimum 25k ohm potentiometer such as as the Mission Engineering EP-25k. For best results to access the full sweep of the parameter range, we recommend an expression pedal that has a 100k ohm or higher potentiometer.
Yes. Once you adjust the secondary function settings on your Strymon pedal they will not change after powering down your pedal until you manually change them again.
Based on customer feedback, in May 2012 we introduced an updated Lex design that includes an internal jumper allowing for selectable TRS stereo input, as well as non-click footswitches. Lex mono input (now discontinued) was manufactured before May 2012 and includes a mono input.
Lex mono input (discontinued) has:
Based on customer feedback, in May 2012 we introduced an updated Lex design that includes an internal jumper allowing for selectable TRS stereo input, as well as non-click footswitches. This FAQ does not apply to Lex mono input (now discontinued), which was manufactured before May 2012 and includes a mono input. Read this FAQ to determine which pedal you have.
The input can be set for either mono input or TRS stereo input. The pedal ships in mono configuration from the factory. Here’s how to adjust this configuration.
Remove the back cover of your pedal.
On the left side of the circuit board, you’ll see a jumper that can be set in two positions. Place the jumper on the left 2 pins for TRS stereo input. Place the jumper on the right 2 pins for mono input.
In order to use the TRS stereo input, you’ll need a TRS stereo input adapter like the one shown below. You can purchase one here.
Sorry, no. There isn’t any way to convert your Lex mono input to Lex (TRS stereo) specs or upgrade to the silent type switches.
The designs are different and parts are not interchangeable.
With the new TRS stereo input on El Capistan, Brigadier, and Lex, the L and R channels are summed together and fed into the effect, where it undergoes identical processing as would a mono input. On El Capistan and Brigadier, the dry portion of the output signal retains its stereo image at the output through the stereo mix control. With Lex, the stereo image is created through the rotating speaker process.
The big advantage of stereo input lies in the ability to place the pedal anywhere within a stereo rig and retain the stereo I/O throughout. All of our pedals continue to make use of the entire processing power of the SHARC DSP chip as they always have.
This info can be found on Page 5 in the Lex user manual.
The EXP pedal jack input can be used for either an Expression Pedal, an External Speed Switch, or an external Favorite switch. Lex is set up to use an Expression pedal by default. There is a quick power-up procedure to tell your Lex how to assign the EXP jack. You only have to do this once.
If you’re using the EXP jack for a Favorite switch:
NOTE: The EXP jack is set up to use an Expression pedal by default.
To set up your Strymon pedal to use a TAP Favorite switch, follow the steps below.
1. Power down your Strymon pedal.
2. Configure pedal and power on.
Pedals with toggle Switches – Set both toggle switches to the MIDDLE position. While holding down both footswitches, power up your pedal.
Pedals without toggle switches – While holding both footswitches, power up your pedal, Continue holding footswitches and turn the topmost left knob fully clockwise.
3. Let go of TAP and BYPASS.
Your pedal has now been configured to use the Favorite Switch.
All Strymon pedals sold within North America (except OB.1) include a 9VDC 660mA power supply. OB.1 includes a 9V battery.
We recommend a power supply that provides 9VDC (center negative) at a minimum of 250mA.
Do not subject your Strymon pedal to any voltage above 9V. Doing so will damage your pedal and void your warranty.
All pedals (except TimeLine, BigSky, and Mobius):
You can, but please take these precautions:
First, please make sure that the dip switch on the bottom of your Pedal Power is set to the NORMAL (9V) position. Do not subject your Strymon pedal to any voltage above 9V. Doing so will damage your pedal and void your warranty.
blueSky, Brigadier, Deco, DIG, El Capistan, Flint, Lex, Ola, and Orbit require a minimum of 250mA of current to operate reliably. You will need to use output 5 or 6 on your Pedal Power 2+. The OB.1 optical compressor only requires 20mA of current because of its all analog circuitry, so you can use outlets 1 through 4 with that pedal. Make sure to use the Pedal Power 2+ as the original Pedal Power 2 does not provide enough current (mA).
A better solution would be to use the Voodoo Lab Pedal Power Digital power supply which offers four (4) 9V DC high current outputs.
We don’t recommend using daisy chain power supplies. Ground loops are commonly caused when using a daisy chain power cable to power multiple pedals. This creates a ground loop between every pedal in the daisy chain. Ground loops allow stray magnetic fields to introduce hum into your signal path.
If the only type of effect you use is distortion you may not have (or hear) the ill effects. But, if you have modulation and delay pedals the likelihood of ground loops wreaking havoc on your signal is high.
If you don’t plan on using your Strymon power supply, we recommend an isolated power supply. The Voodoo Labs Pedal Power Digital and Iso-5 are some examples of cost effective, multiple output isolated power supplies. An isolated supply works by using a transformer (or multiple transformers) to keep every power outlet completely electrically isolated.
All of the inputs and outputs on our Strymon pedals use MONO TS unbalanced connections. You can use a TRS cable to plug into the inputs and outputs of the pedals, however, there is no benefit to using TRS balanced cable over a MONO TS instrument cable.
All Strymon products are crafted with love in the USA, right in the Los Angeles, California area.
blueSky, Brigadier, Deco, El Capistan, Flint, Lex, OB.1, Ola, and Orbit are all 4.5″ deep x 4″ wide x 1.75″ tall.
