CAUTION:

Earthquake products are capable of generating high sound pressure levels. You should exercise caution when operating these products. Long-term exposures to high levels of sound pressure will cause permanent damage to your hearing. Sound pressure levels exceeding 85dB can be dangerous with constant exposure. Set your audio system to a comfortable loudness level. Earthquake Sound Corporation does not assume liability for damages resulting from the direct use of Earthquake amplifier or other Earthquake products and urges users to play their music at moderate listening levels.

Thank you for choosing Earthquake Sound’s EQ-4000BT v2 equalizer for supe­rior enhancement of your mobile audio system. With proper installation and responsible listening, your equalizer(s) will give you years of near perfect sound reproduction. We strongly recommend you to have your new equalizer(s) in­stalled by an authorized Earthquake Sound dealer. Installation professionals employed by your dealer have the correct tools and knowledge to install your product neatly and successfully. Also, when your new products are installed by an authorized dealer, your product will include a FIVE (5) YEAR LIMITED WAR­RANTY.

If you choose to perform your own installation, your warranty will be subject to limitations. Dealer policies on handling warranty requests may vary from one dealer to the next. Please read the warranty information (page 11) in its entirety and use good judgment when making these vital decisions.

CARE AND MAINTENANCE

Your Earthquake Stereo 4-Band Graphic Equalizer is an example of superior design and craftsmanship. The following advisories will help you care for your equalizer so you can enjoy it for years to come.

Keep the parametric equalizer dry. If it gets wet, wipe it dry im­mediately. Liquids contain minerals that can corrode electronic circuits. Additionally, liquids can cause severe electrical shock.

Use and store the parametric equalizer only in normal tempera­ture environments. Temperature extremes can shorten the life of electronic devices and warp or melt plastic parts.

Handle the parametric equalizer gently and carefully. Dropping it can damage the circuits or cause components to break or be­come loose. These kinds of actions can cause the units to work poorly or improperly.

Keep the parametric equalizer away from dust and dirt, which can cause premature wear of parts.

EQ-4000BT v2 FRONT PANEL OVERVIEW

1. FADER
   Use this rotary knob to blend more action into either the Front or Rear channels of the system.

2. VOLUME CONTROL
   Push in once to eject button then rotate to adjust volume.

3. AUX/MAIN SELECTOR
   Push button to switch between the MAIN input and AUX input. Note that the EQ- 4000BT v2 has both front-mounted and back-mounted auxiliary inputs. If the front-mounted auxiliary input is in use (when an audio source is plugged in through the front 3.5mm jack), the EQ-4000BT v2 will automatically treat that audio source as the MAIN input.

4. BT ON/OFF SWITCH
   Push button to turn the Bluetooth® feature on or off of the EQ- 40008Tv2. To connect your device to the EQ-4000BTv2, pop the BT button, enable the Bluetooth ® of your device and pair to the EQ-4000BTv2. You can then wirelessly play music from your device. If you want to switch back to the MAIN/AUX input, push the BT button in and the Bluetooth® feature will be disabled.

5. SUBGAIN&SUBFREQCONTROLS
   Gives you complete control of low musical frequency ranges.The Sub knob is equal to level control. It allows you to adjust subwoofer sound levels for a particular source type: Tape, broad-cast, CD, etc.
   The subwoofer frequency crossover control allows you to adjust the cross-over point for your subwoofer system. The EQ-4000BT v2 features separate dual RCA outputs for the subwoofer channel, so that the subwoofer(s) can run on a separate amplifier or separate channels of a multi-channel amplifier. The crossover is adjustable from 35Hz-120Hz. Depending on the subwoofer frequency response, adjust this knob to the most desired setting.

6. 4-BAND EQUALIZATION CONTROLS
   Gives you control of the higher musical frequency ranges that most head units cannot accomplish.

7. 3.5MMAUXIN
   This feature is used for connecting devices through a 3.5mm auxiliary cable. Once this connection has been made, it will override the MAIN input plugged into the back of the unit.

INPUT GAIN SETTINGS

Designed to set the maximum upper volume level, the Input Gain is a tool for installer to protect the system from excessive-high volume.Note that the Input Gain level depends on thesources’maximumsignal strength (expressed in Voltage). Your installer will need to know the output voltage of the source unit(s) in order to set the Input Gain accordingly.
Below, please find sample settings of the Input Gain according to the source units’ output voltages:

EQ-4000BTv2

Input Gain’s Position| Source Voltage| Volume Control Position| Front & Rear Output V@0.1%THD| Subwoofer Output Voltage (Sub Gain @ MAX)
---|---|---|---|---
9 O’clock| >13V| MAX| 4.2V| sv
12 O’clock| 2V| MAX| 4V| SV
3 O’clock| 1V| MAX| 3V| SV
MAX| 200mV| MAX| 600mV| 1.6V
