POWERBASS AMPLIFIED BASS SYSTEM fEATURES BUILT-IN HIGH POWERED AMPLIFIER: Contains a high power Class D monaural amplifier complete with chassis mounted adjustable Gain, Low Pass Filter and Bass Eq controls for sonic integration into most existing factory or aftermarket car stereo systems and engineered perfectly to power the subwoofer. SELECTABLE SENSITIVITY SETTING: With this button pressed in, the preamp sensitivity will accept input voltages from 2V-1 OV.

Fig.1 Possible locations for installation CONNECTIONS TO AMPLIFIER FOR BATT+, GND and REM For maximum transfer of Voltage it is highly recommended to attach insulated Ring and/or Spade terminals to wire ends connecting to the amplifier for Power Connections. These terminals (not supplied) should be soldered or at the very least crimped to the wire-make sure no wire strands stray outside the terminal barrel.

Before final mounting, be sure to check the sound one last time and make sure the enclosure is properly placed to produce the desired bass output. Use the four mounting 20mm screws provided and secure them to the enclosure. Mounting holes located on the top of the unit.
STA-10 AMPLIFER CONTROL PANEL LAYOUT 3 11 Fig.2 1. REMOTE LEVEL (3.5mm Input Jack) This is the connector port for the STA Remote Level control. Now the amplifiers secondary gain circuit can be adjusted from the driver's seat. 2. HIGH INPUT Use the High Input 4-pin Molex style jack when connecting to the speaker leads directly from a factory radio without the use of a low level convertor. Be sure to observe the correct speaker polarity. (Do not use if you are using the LOW INPUT from the RCA jacks). 3.
6. LPF (Low Pass Filter) Control This filter allows the low pass of frequency and has an adjustable crossover point from 40Hz to 200Hz. A setting of 40Hz will produce only the low frequencies (deep bass). A max setting of 200Hz will allow the amplifier to produce a more punchy (higher) bass response. 7. SUB SONIC Control This control is continuously adjustable from 20Hz-50Hz at 12dB per octave to provide an extra level of speaker protection from bass robbing power at unheard frequencies 8.
POWER WIRING AND SIGNAL CONNECTIONS POWER CONNECTION BATT+ The amplifier should be wired directly to the vehicle battery using a 8ga power cable. Start at the vehicle battery and run the power cable through the vehicle's firewall using grommets to the amplifier's BATT + screw terminal. If factory grommets are not available install grommets yourself to protect the cable from sharp metal edges. Avoid running the power cable over the engine components and near heater cores.
INPUT SIGNAL (CHOOSING THE HIGH OR LOW INPUTS) The STA amplifer control panel input signal connects to the head unit's High Level (speaker wire) output OR Low Level (RCA) output-provided the radio is so equipped with Line Out. A dedicated subwoofer or low level signal will deliver the best performance. If unavailable use the high level inputs, as will be the case with most factory head units.
CHASSIS GROUND © +- -- ® +- FUSE HOLDER within 18" of Battery Fig.4 High Level Connections NOTE: Use 8ga power/ground wire for BATT+ and GND connections. Remote lead is not needed with a High Level connection but is strongly recommended.
Low Level Input and RCA Interconnect Wiring (fig 5) For radios that have RCA line outputs. You will need to connect the low-level RCA style inputs from the STA to the line-outputs from the radio (source) via an RCA interconnect commonly called a "stereo patch cord". Choose the correct length and style of RCA interconnects for your needs.
SET UP ADJUSTMENTS Your STA enclosure uses several controls to provide sonic integration with virtually any vehicles unique acoustic properties. Please read the following section carefully to familiarize yourself with the function of each control. The following adjustment sequence is recommended to properly tune your STA enclosure. By first adjusting the GAIN, the LPF, then the PHASE switch, followed by the BASS EQ (in this order) will give you the best results. GAIN ffi MIN MAX Fig.
0° 180° Fig.8 PHASE Switch Setting the PHASE switch Start with the PHASE switch set at o· and play a favorite music track that contains some solid bass (make sure the BASS EQ control is set at the 12 o'clock position). Then flip the switch to 180° and listen to the same musical track again. Choose the setting that provides the best bass response according to your taste. BASS EQ □ dB 12dB Fig.
Fig.1 ORemote Level Controller/ PB-GAIN1 Remote Level Controller Your PowerBass STA enclosure includes a wired Remote Level Subwoofer control module. To connect the Remote Subwoofer Gain control to the amplified enclosure, simply insert 3.5mm input jack into the REMOTE gain port. Mount the module within easy reach or under your dash.
TROUBLESHOOTING TIPS Problem Solution Power BLUE LED not ON With a Volt OHM Meter (VOM) check: • + 12 Volt power terminal (should read +12 to + 16VDC • Remote turn-on terminal (should read +12 to + 16VDC) • Ground Terminal Power LED lights BLUE, no output • • • Check RCA connections Substitute known good Source Unit Check for signal on the RCA cable with VOM in AC position • Thermal protection is engaged. Check for proper impedance at speaker terminals.
