electro-harmonix Nano Battalion Bass Preamp and Overdrive User Manual

NANO BATTALIONBASS PREAMP + OVERDRIVE

Congratulations on your purchase of the Electro-Harmonix Nano Battalion. The all-analog circuitry of the Nano Battalion provides you with an amazing variety of bass tones in a sturdy and compact pedal. At the core of the Nano Battalion’s tone is a versatile MOSFET drive circuit that can range from subtle, light overdrive to fully saturated distortion. A flexible three-band equalizer includes a three-way EQ Position switch to select where the EQ falls in the pedal’s signal path. The Nano Battalion features a normal ¼” input, plus a ¼” output that can output either a normal, unbalanced signal (with a normal TS cable) or a balanced signal (with a TRS cable) to go right into a mixing console or recording interface. The Nano Battalion features buffered bypass and runs on a standard 9.6VDC center-negative supply, drawing 45mA.

Using the Nano Battalion 

Plug the 9VDC adapter into the jack on the top of the Nano Battalion. The unit must be powered to pass signal even in bypass. Connect an instrument cable from your bass into the INPUT jack. Insert a normal TS instrument cable between the OUTPUT jack and a suitable amplifier, or insert a TRS cable (or TRS to male XLR cable) between the OUTPUT jack and a suitable mixing console or recording interface. Click the BYPASS footswitch to engage the Nano Battalion. The LED lights to indicate that the unit is active.WARNING: Your Nano Battalion comes equipped with an Electro-Harmonix 9.6DC-200BI power supply (same as used by Boss® & Ibanez®: 9.6 Volts DC 200mA). The Nano Battalion requires 45mA at 9VDC with a center-negative plug. Use of the wrong adapter or a plug with the wrong polarity may damage your Nano Battalion and void the warranty.

Main Control 

BYPASS Footswitch & LED ­ The LED illuminates when the effect is engaged. The LED will not light if the Nano Battalion is bypassed. Press the footswitch to toggle between effect on and buffered bypass mode.VOL Knob ­ Sets master output level of the pedal.BLEND Knob ­ Sets the ratio between clean signal and distorted signal. Turn BLEND up for a more distorted signal.DRIVE Knob ­ Sets the intensity and saturation of the distortion.TONE Knob ­ Cuts high frequencies from the distortion as the knob is turned down.EQ CONTROLS:TREBLE Knob ­ Boost or cut high-end. No effect when the knob is at 50%. Boosts/cuts frequencies starting above 1kHz. Maximum boost/cut about +/-12dB around 5kHz.BASS Knob ­ Boost or cut low end. No effect when the knob is at 50%. Boosts/cuts frequencies starting below 200Hz. Maximum boost/cut about +/-12dB around 60Hz. MID Switch ­ No effect when the switch is in the middle position. In the upwards position, 9dB boosts around 500Hz. In the downwards position, 9dB cut around 500Hz.

EQ POS. & Signal Path

The EQ POS switch determines where the EQ (TREBLE, BASS, and MID controls) falls in the Nano Battalion’s signal path. In all cases, the TONE knob controls follow immediately after the distorted signal, regardless of EQ position, and the VOL control is last in the signal path. There are three EQ POS modes, as illustrated below.

DIST MODE:

In DIST mode the EQ comes after the distortion signal, having a strong effect on the sound of the distorted signal. The clean signal is not affected by the EQ at all.INPUT MODE:

In INPUT mode the EQ comes first in the signal path, affecting both the clean signal and the signal fed into the distortion. Boosting frequencies in this mode can help drive the distortion signal to a more saturated tone.DRY MODE:

In DRY mode the EQ affects the clean signal but doesn’t affect the distorted signal at all.

I/O & Power

INPUT ­ Plug your bass, or the output of another effects unit, into this jack with a standard ¼” TS cable. The Nano Battalion has an input impedance of 1M.OUTPUT ­ This jack can output an unbalanced or balanced signal. An unbalanced signal is the more standard output type for an effects pedal. Plug a normal ¼” TS cable into this jack to output an unbalanced signal. Use this to plug the output of the Nano Battalion into a bass amp or another effects unit. To output, a balanced signal, plug a TRS cable into this jack. Use this to plug the output of the Nano Battalion directly into a mixing console or recording interface, or other situations where you would use a DI box. Use a TRS to male XLR cable to plug the output of the Nano Battalion into an XLR input.9V Power Jack ­ Plug the output of the included EHX 9.6DC-200 adapter into the 9V power jack of the Nano Battalion. The Nano Battalion draws 45mA at 9VDC with a center-negative plug. The Nano Battalion accepts Boss® and Ibanez® style AC Adapters capable of delivering at least 100mA. The Nano Battalion does not accept batteries and only works with an external 9V power supply. Do not open the unit as there are no user-serviceable parts.

The CE logo indicates that this product has been tested and shown to conform with all applicable European Conformity directives.
