Notes And Specifications - Electro-Harmonix Nano Q-Tron Quick Start Manual

2. MODE Rotary Switch (LP / BP / HP) Determines the frequency range
that the filter allows to pass through. LP (Lowpass) mode emphasizes low
frequencies, BP (Bandpass) middle frequencies and HP (Highpass) high
frequencies.
3. Q Knob Sets the bandwidth of the filter. As Q is turned clockwise, the
filter sounds more resonant or peakier, making the envelope effect more
dramatic. Low settings of Q yield a less intense filter curve. Start with Q
set to about 2 o'clock for a middle-of-the-road filter intensity.
4. VOL Knob Adjusts the overall volume at the OUTPUT jack. As VOL is
turned clockwise, the output level increases. Use VOL to match the effect
volume to your bypass volume or give the effect a volume boost.
5. FOOTSWITCH and STATUS LED The footswitch engages or bypasses the
effect. The Status LED lights when the effect is engaged. The LED is off in
bypass mode. The Nano Q-Tron employs True Bypass.
6. INPUT Jack Audio input to the Nano Q-Tron.
7. AMP Jack Audio output from the Nano Q-Tron. In bypass mode, the AMP
jack is directly connected to the INPUT jack.
8. 9V Power Jack An optional 9VDC, center-negative power supply can be
connected to the power jack to provide power without a battery. The Nano
Q-Tron requires 10mA at 9VDC on a center-negative plug. Do not exceed
12VDC at the power jack.
When using a 9V battery, plugging into the INPUT jack activates power.
The input cable should be removed when the unit is not in use to avoid
running down the battery.
To change the 9-volt battery, you must remove the 4 screws on the bottom
of the Nano Q-Tron. Once the screws are removed, you can take off the
bottom plate and change the battery. Please do not touch the circuit board
or adjust the trim pot while the bottom plate is off or you may damage a
component or set the filter sweep range to a non-ideal setting.
