****** Page 1 ****** electro-barmonix SWITCHBLADE PRO Congratulations on your purchase of the Switchblade Pro, our deluxe switching box featuring true mechanical bypass, soft switching, high quality and low noise buffers, volume controls for all input signals, high headroom, and a multitude of different possible configurations for all of your signal routing needs. CONTROLS 9V Power Jack – The SWITCHBLADE PRO operates with a standard 9VDC AC Adaptor capable of delivering at least 170mA to the 9V power jack, such as the EHX9.6DC-200. The AC Adapter must have a center negative plug. The SWITCHBLADE PRO has a current draw of 165mA at 9VDC. This iV jack is the audio input of the SWITCHBLADE PRO. The input INPUT Jack impedance is 2.2MQ. This input will accept any audio source that is instrument or line level up to 4.2Vp-p without clipping. SEND A Jack — This 1/4″ jack is an audio output of the SWITCHBLADE PRO. Connect this to the input of the effect(s) you want in FX loop A or send it to the input of an amplifier. The output impedance is 220Q. RETURN A Jack This 1/4″ jack is an audio Input of the SWITCHBLADE PRO. Connect this jack to the output of the effect(s) you want in FX loop A. This jack can also accept another instrument output. The input impedance is 90kQ. SEND B Jack — This 1/4″ jack is an audio output of the SWITCHBLADE PRO. Connect this to the input of the effect(s) you want in FX loop B or send it to the input of an amplifier. The output impedance is 220Q. This 1/4″ jack is an audio input of the SWITCHBLADE PRO. Connect this RETURN B Jack jack to the output of the effect(s) you want in FX loop B. This jack can also accept another instrument output. The input impedance is 90kQ. A LEVEL Knob Controls the volume of signal going into the RETURN A jack. Unity gain is achieved with the knob at 12:00. Turning this knob fully clockwise achieves a gain of 6dB. DRY LEVEL Knob — Controls the volume of signal going into the INPUT jack. Unity gain is achieved with the knob at 12:00. Turning this knob fully clockwise achieves a gain of 6dB. B LEVEL Knob — Controls the volume of signal going into the RETURN B jack. Unity gain is achieved with the knob at 12:00. Turning this knob fully clockwise achieves a gain of 6dB. SERIES/ PARALLEL Switch This switch works in conjunction with the A/B and A+B footswitches to determine how the input signal is routed through the A and B FX loops. In SERIES mode, the FX loops are cascaded into one another with the A/B footswitch determining which FX loop is first. See Fig. 1.
****** Page 2 ****** IN FX LOOP A FX LOOP B OUT Fig. 1. Series Mode Switchblade Pro series signal flow with FX loop A selected and A+B engaged In PARALLEL mode, the input signal is routed to the A and B FX loops simultaneously. With the A+B footswitch engaged, both signals will be mixed together at the output. With the A+B footswitch disengaged, only FX loop A or B will be engaged which is determined by the A/B footswitch. See Fig. 2. IN FX LOOP A OUT FX LOOP B Fig. 2. Parallel Mode Switchblade Pro parallel signal flow with A+B engaged (A/B setting irrelevant) If using the SWITCHBLADE PRO to switch between two amplifiers, set the SERIES/PARALLEL switch to PARALLEL in order to utilize both amps at the same time. BYPASS FOOTSWITCH – This soft footswitch engages the SWITCHBLADE PRO, routing the signal on the INPUT jack to the SEND jacks. The signal routing is via relay and true mechanical bypass. A/ B FOOTSWITCH — This soft footswitch selects between FX loop A (RED) and FX loop B (GREEN). With the SERIES/PARALLEL switch set to SERIES mode and the A+B footswitch engaged (both FX loops on), the A/B footswitch determines which FX loop is flrst in the signal chain. A+B FOOTSWITCH — This soft footswitch engages both FX loops A and B, regardless of configuration (e.g. two effects loops, two amps via the SEND jacks, two instruments via the RETURN jacks, etc.). PHASE A & B SWITCHES These internal slide switches allow the signals at the SEND A and SEND B jacks to be flipped 1800. This is for use with effects whose output signals are out of phase with the input signal. To access these switches, remove the four screws on the bottom of the SWITCHBLADE PRO and remove the lid. Be careful not to touch any components other than the PHASE A/B switches for danger of shocking sensitive components.
****** Page 3 ****** CONFIGURATIONS The SWITCHBLADE PRO offers many different possible conflgurations to satisfy your various effects pedal, amp, and instrument routing needs. Here are a few examples. SERIES EFFECTS Shown below are two effects chains that can be used individually as clean (delay and reverb) and dirty (overdrive and phaser) sounds, but can also be used in series (FX loop B -5 FX loop A) when engaging the A+B footswitch. 000 eoe 00 OOO IO REVERB DELAY FX LOOP A eoe PHASER OD FX LOOP B O RETURN B RETURN A A LEVEL SEND A SERIES < DRY LEVEL SEND B B LEVEL BYPASS B (GREEN) OFF ****** Page 4 ****** CONFIGURATIONS (cont.) PARALLEL EFFECTS This is an example of two effects chains that you may want to use in parallel. The synth pedal is feeding the delay in FX loop B while the compressor is feeding the reverb pedal in FX loop A. With the SERIES/PARALLEL toggle switch set to PARALLEL, each FX loop is independent and does not affect the other. The outputs of each FX loop are summed and sent to the guitar amp. 00 OOO IO 000 REVERB eoe COMP DELAY SYNTH FX LOOP A FX LOOP B RETURN A A LEVEL SEND A O RETURN B PARALLEL DRY LEVEL BYPASS ON SEND B B LEVEL ****** Page 5 ****** CONFIGURATIONS (cont.) TWO AMPLIFIERS Utilizing just the SEND jacks of the Switchblade Pro will allow you to split your signal between two amps. Use the A/B footswitch to switch between SEND A and SEND B. The SERIES/PARALLEL toggle switch only needs to be set to PARALLEL if you want to use both outputs at the same time (A+B). Note: To avoid hum, the ground connection on one of the amplifiers may need to be lifted. Either use the ground lift feature on the amplifier or use a 3-prong-to- 2-prong power adapter (aka "cheater plug" or "AC ground lifter"). oo 000100 0000 SEND A RETURN A O A LEVEL SEND A SEND B O RETURN B PARALLEL O DRY LEVEL SEND B O B LEVEL BYPASS A (RED) OFF ****** Page 6 ****** CONFIGURATIONS (cont.) THREE INSTRUMENTS TO ONE AMPLIFIER A multi-instrumentalist can use the Switchblade Pro to connect up to three instruments to a single amplifler. To engage the guitar in the example below, put the Switchblade Pro into bypass. Engaging the Switchblade Pro allows you to switch between either the electric violin or the keyboard and the volume of each instrument is controlled by the A and B LEVEL knobs. oo 00010 RETURN A RETURN B o SEND A SERIES O O RETURN B RETURN A A LEVEL SEND B B LEVEL DRY LEVEL BYPASS A (RED) OFF ****** Page 7 ****** CONFIGURATIONS (cont.) INSTRUMENT MIXER In a similar configuration as the previous example, switching to PARALLEL mode allows you to mix all three instruments together. This could be useful for three players to play into a single amp, or for an electronic music setup.

VINTAGE PEDAL TRUE BYPASS WITH DRY BLEND With its DRY LEVEL control, the Switchblade Pro is great for bass players, especially those who may have vintage pedals that do not have true bypass. Below is an example setup where the output not only has the original input signal mixed in, but it is also not susceptible to tone-suck when the pedals in the FX loops are disengaged. 00000 o eoe O DISTORTION FX LOOP A CHORUS FX LOOP B O RETURN B RETURN A A LEVEL SEND A SERIES SEND B DRY LEVEL BYPASS A (RED) ON ****** Page 10 ****** FUNCTIONAL BLOCK DIAGRAM O O ****** Page 11 ****** ADVANCED MODES & CONFIGURATIONS During normal operation, when an FX loop is inactive the signal coming out of that loop's SEND jack and any signal coming into that loop's RETURN jack are muted. The Switchblade Pro enables you to disable either mute in both FX loops for an even broader range of switching applications. UNMUTE SEND A/B This can be useful for any application where you want the INPUT signal routed to SEND B to stay active when FX loop A is selected (or vice versa). For example, you may use this as a "dry out" to send to another amp or effects chain and want it to stay active at all times. How to disable SEND A/B mute: 1. Select the channel whose SEND you want to unmute with the A/B footswitch (RED = A, GREEN = B). 2. Press and hold the A+B footswitch for at least 3 seconds. 3. The A+B LED will blink rapidly to signify that the selected FX loop's SEND has been unmuted. How to re-enable SEND A/B mute: 1. Select the channel whose SEND mute you want to re-enable with the A/B footswitch (RED = A, GREEN = B). 2. Press and hold the A+B footswitch for at least 3 seconds. 3. The A+B LED will blink slowly to signify that the selected FX loop's SEND mute has been re-enabled (normal operation). UNMUTE RETURN A/ B — This can be useful for any application where you want the signal plugged into the RETURN B jack to stay active when FX loop A is selected (or vice versa). For example, you may use this to retain the tails of a delay or reverb in FX loop B when switching back to FX loop A. How to disable RETURN A/B mute: 1. Select the channel whose RETURN you want to unmute with the A/B footswitch (RED = A, GREEN = B). 2. Press and hold the BYPASS footswitch for at least 3 seconds. 3. The BYPASS LED will blink rapidly to signify that the selected FX loop's RETURN has been unmuted. How to re-enable RETURN AIB mute: 1. Select the channel whose RETURN mute you want to re-enable with the A/B footswitch (RED = A, GREEN = B). 2. Press and hold the BYPASS footswitch for at least 3 seconds. 3. The BYPASS LED will blink slowly to signify that the selected FX loop's RETURN mute has been re-enabled (normal operation). Note: If you disable the muting of both the SEND and RETURN ofa given FX loop, that loop will remain always active regardless of the state of the footswitches/LEDs. If this is an undesirable state for you, see the factory reset instructions below. ****** Page 12 ****** FACTORY RESET — If you were experimenting with unmuting the SENDs and RETURNs and want to reset the Switchblade Pro back to its original, out-of-the-box factory settings, perform these steps: 1. 2. 3. Unplug the AC adapter power cable from the Switchblade Pro. Hold down the A/B footswitch and plug the AC adapter power cable in, continuing to hold down the A/B footswitch for at least 3 seconds. If all of the LEDs blink rapidly and the Switchblade Pro shows both the A/B LED and BYPASS LED as RED, then the factory reset was successful.
