Detailed Information: DUAL VITALIZED ROUTING INTERFACE DVI-1M

In and Out Vitalizer will keep the original sound as much as possible to low impedance the signal. This will avoid signal deterioration via many signal contacts such as jacks, plugs, switches and long cables.

Dual Vitalizer Equipped

Minimizes changes in signal sound quality, converts to low impedance, prevents sound quality changes or degradation in pedal systems or with long cables, and stabilizes the signal. Vitalizers are provided in two lines: after the IN input and after the RETURN input, allowing the Vitalizer to function in any routing set.

SEND/RETURN

The jacks are located to allow efficient routing of the input/ output for your pedalboard system.
TUNER OUT (Can also be used as a parallel output box)
Usually, a tuner is connected, but it can also function as a 3 parallel output box by switching the internal switch.

MUTE CTL

Using a third-party external latch footswitch for mute function.
It will mute the signal at the end of your effect chain when using the Send/Return. This will help to shut the noise or unnecessary sound reflection caused by the pedalboard system.

POP NOISE REDUCTION CIRCUIT

The mute circuit uses a relay contact circuit that does not change the sound quality. Besides, a POP noise reduction circuit is also installed to reduce the pop noise when the mute function is switched.

POWER/MUTE (LED)

When the power is on, the LED will light blue, when the mute function is active, the LED will blink red.

THRU

This THRU is structured as a stereo phone (TRS), and the signal line (Tip and Ring) and the ground line (sleeve) of 2 signals are completely isolated. It can be used for a variety of purposes as switching systems, amp channel selecting and two signal connections to external devices.

Wide Voltage DC Input

Various voltages from + 9 V to +18 V are usable. 006P battery is usable as well.

Detailed Information: Provolt9 PV-9

The Provolt9, with its auto-voltage controller function, supplies approximately 9.6V (the voltage of a new alkaline battery) to low-current-draw effects pedals where dynamics are crucial, such as boosters, overdrives, and distortions.

Short Protection & Auto-Recovery Function

If any of the Provolt9 DC outputs are accidentally shorted, this feature protects the internal circuitry from damage while keeping all other outputs active. When the cause of the short is removed the affected output will recover automatically and normal DC supply will resume.

Auto Voltage Controller Delivers Ideal Output for Each Effect Device

Although the output from most power supplies designed for use with effect pedals is 9 volts DC, the output from a brand new battery can be anywhere from about 9.4 to 9.8 volts. It's a small difference, but it can mean a noticeable change in sound quality. The Provolt9 Auto Voltage Controller ensures that approximately 9.6 volts DC (equivalent to a new alkaline battery) is consistently supplied to booster, overdrive, distortion, and other low-power-consumption effect pedals that need to deliver outstanding dynamic performance. That 0.6 volt difference can be a significant sonic advantage.

Double Filtering for Refined Sound

Double Filtering on each of the Provolt9 outputs ensures exceptionally clean power supply. Clean power is essential for highresolution, refined sound.

Star Grounding to Suppress Hum Noise

In most power supplies with multiple outputs the DC output jacks are simply connected in parallel – a configuration that increases the likelihood of hum. The Provolt9 employs star grounding that effectively suppresses hum for clean, high-quality sound.

Detailed Information: P-4TB True Bypass Box

The P-4 Routing Box Series inherited original P-1, P-2, P-3 series' top notch quality that were highly acclaimed by musicians since its first release in 1999 for more affordable price while maintaining hand wiring production and using well selected parts with special wiring method to minimize the noise by reviewing work efficiency that are not related to the sound quality and durability and renewing the body design.

P-4TB TRUE BYPASS offers true bypass feature that completely bypasses the effect pedals that are connected in between send and return. Some of the effect pedals degrade the sound quality because of the low input impedance, and some others can't bypass the buffer even though the effected is turned off. The P-4TB is very helpful to solve these situations.

Detailed Information: P-4E A/B Box

The P-4 Routing Box Series inherited original P-1, P-2, P-3 series' top notch quality that were highly acclaimed by musicians since its first release in 1999 for more affordable price while maintaining hand wiring production and using well selected parts with special wiring method to minimize the noise by reviewing work efficiency that are not related to the sound quality and durability and renewing the body design.

Providence P-4E is the A/B Box equipped with the Switchcraft jack and Providence OFC wire to minimize the sound degradation. The LED turns on by selecting A OUT. Unselected signal will be grounded, and input from the amp or effect pedal will be muted. It is same situation as the guitar or bass' volume is all way down where noise level is minimum. It avoids translating noise from cables, amp, and effect pedals' input and prevent the noise to come through from amp's output as well as crosstalk interference. For example, by connecting A out to a tuner and B out to the rest of your signal chain, and choose A OUT, you'll be able to tune with mute on.

Detailed Information: P-4LE 1 Loop + A/B Box

The P-4 Routing Box Series inherited original P-1, P-2, P-3 series' top notch quality that were highly acclaimed by musicians since its first release in 1999 for more affordable price while maintaining hand wiring production and using well selected parts with special wiring method to minimize the noise by reviewing work efficiency that are not related to the sound quality and durability and renewing the body design.

This is a model of the P-4E (A/B Box) with Effect loop. The effect loop is placed before A/B selector. If nothing is connected to the loop, the signal will be bypassed. Since the loop's ON/OFF can be visually seen by LED, this will be a suitable function for the units such as vintage effect pedals that are not equipped LED to check whether it is on or off. Also, some of the effect pedals go through buffer circuit even the pedal is off. Some players prefer not to use buffer when the pedal is off. The P-4 LE is designed to have completely separated signal line for the loop to answer these needs. We employed original measurement to ensure turning on and off reliable by having 60mm space in between the switches.
