Maxon PAC-9 Pure Analog Chorus Pedal

• Analog chorus with lush, organic tone
• Wide-range Speed control for Rotary speaker effects
• Special noise filtering circuit
• Bright and Pure switches for additional tonal options
• Stereo outputs
• Works in FX loop or front-end of amp
• True Bypass Switching

The first thing you’ll notice when you step on the PAC-9 is a beefy, full-bodied chorusing that punches you directly in the chest – gone are the thin, hissy, sissified chorus tones of yesteryear, replaced instead by a full-frequency effect that simply sounds massive.

The PAC-9’s circuit uses professional-grade IC’s typically reserved for High-End Audio applications, providing audiophile performance in a compact stompbox format.

When compared to a standard chorus, the PAC-9’s effect appears more dramatic and has more presence in a mix – this is due to the retention of low and low-mid frequencies that are typically chopped out by other boxes.

The PAC-9’s LFO has an extended range that allows it to nail classic rotary speaker sounds with ease.  In addition to standard Speed and Width controls, The PAC-9 also features two unique controls:  The Pure switch boosts the delayed signal by 4 dB to create a more dramatic, tremolo-like chorus effect, while the Bright switch subtly scoops lows on the delayed signal for a more traditional chorusing sound.

Standard and inverted (90 degrees out of phase) outputs allow for mono, stereo, or inverted mono signal routing options.

The PAC-9’s internal voltage-doubling circuitry provides maximum headroom to eliminate input distortion.  The higher operating voltage also allows it to be used in an FX loop to place the chorus effect post-gain.

A new spin on an old classic, the PAC-9 brings classic 80’s chorusing into the 21st century with modern features and improved sound quality.

TECH TALK

NOTE ON POWERING THE PAC-9 - this pedal’s voltage regulator IC requires a high inrush current of approximately 2000 mA upon startup.  When using with a Power Brick such as the Voodoo Labs Pedal Power 2+, this pedal should be connected to a high current power jack when possible.

If it is not possible to connect to a high current jack, you can power the PAC-9 by leaving a battery in the pedal.  Upon initial start-up, unplug the external DC power input cable, engage the pedal, and then plug the DC power input cable back in – the pedal will now power up normally off the external power supply until you power down your pedalboard.
