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.

"The Maxon PAC-9 provides a large range of great chorus sounds with completely silent operation. I had never used choruses before this one, as they often resulted in tones that sounded overly processed for my personal taste. This one allows for lovely subtlety, and is rugged and straight-forward to use." - Gretchen Menn - www.gretchenmenn.com

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.
