WIRING
ST-12PRO or HS-SUB12 in 70v
Powering the ST-12PRO or HS-SUB-12 in 70v (Standard Mode)
Connect the red wire (70v+) and the black wire (70v-) to the 70v amplifier.

ST-10PRO
Powering the ST-10PRO in 4Ω
Connect the red wire (+) and the black wire (-) to the 4Ω amplifier

Powering the ST-12PRO or HS-SUB12 in 4Ω
Connect the yellow wire (4Ω+ positive input) and the blue wire (4Ω – negative input) to the 4Ω amplifier.
SPECIAL NOTE: Make sure your subwoofer amplifier can handle a 4Ω load and has a maximum wattage output of no more than 200 watts.
TruAudio recommends running the st-12PRO and HS-SUB12 in 70v with an LEA amplifier using a custom DSP designed by TruAudio for maximum performance.

WIRING cont.
70V Tap Settings
Set taps to desired listening level. The tap settings can be changed as long as the total speaker wattage does NOT exceed 100% of the amp’s power.
NOTE: Lower tap settings allow for more speakers but a lower maximum volume.

Finding the Correct Tap Setting
Example:
AMP POWER = 700W
700W ÷ 64W (Tap setting) = 10 Speakers
OR
700W ÷ 50W (Tap setting) = 14 Speakers
OR
700W ÷ 30W (Tap setting) = 23 Speakers

NOTE: If using 70V, the Acoustiscape speakers MUST be set to the proper TAP setting prior to connecting it to the amplifier. The speaker will blow if set to 8Ω and will not be covered by warranty. The higher the TAP setting the more power it will receive from the amplifier and the louder the speaker will go. The TAP settings give the listener greater flexibility for layout design. It also allows each speaker to be tapped at different levels creating an even sound stage.
