General Operation
The BTC Control is a 2-band equalizer for Bass guitar. The BTC features single-pole filters for broadband equalization. Often the broader
single-pole filters are preferred for musical instruments because they are less selective, easier on the ear, and sound more “musical”. One of
the features of the BTC Control is a 2-position dip-switch that controls the slope of the high frequency response. By choosing one of the four
combinations the high frequency response can be tailored to your liking. The BTC Control has a high input impedance and can be used with active
or passive pickups. Bass and Treble controls are mounted on a concentric shaft and knobs are included.
Battery Power:
If you play the instrument very hard, and are boosting the bass or treble with the BTS, you should consider operating the instrument on +18
Volts (2 Batteries in series, see page 4). If you play mildly and use a minimum of boost the instrument should operate easily on a single 9-Volt
battery. Use an Alkaline or Lithium battery for the best battery life and always unplug your guitar when you’re not using it.

Installation Instructions:
EMG Model: BTC Control
High Frequency Response Selection:
The BTC has the added feature of allowing you to choose from 4 different
high frequency response curves. This is a nice feature especially if you are
using the BTC with passive pickups. The following diagrams show the dip-switch
positions and the graphs show the resultant frequency response.
The BTC Control is an equalizer style control, offering both boost and cut
at the same frequency locations. The controls feature a center detent (notch)
that lets you know when no equalization is in effect.

The BTC Control is easily installed by using the connector cables supplied.
Diagram #1 shows the cables connected to the BTC Control. This 5-pin
layout is the same for all EMG Accessories, so they can be interchanged.
There are a variety of ways instruments can be wired. The examples shown
here are only a few. If your instrument has different wiring than shown here
go to our website: http://www.emgpickups.com for alternate diagrams.
