SpeciÞ cations (Signature Edition)
AmpliÞ er Output
2,700 watts rms (3.3 Ω impedance)
High Cut Filter
30 Hz - 100 Hz adjustable, with a
"Bypass" position.
Frequency Response
16 Hz - 100 Hz
Power Line Voltage
US model
120 VAC 50/60 Hz
International model
230 VAC 50/60 Hz
Dimensions
13" x 13" x 13"
Weight
53 lbs
Finish
High gloss, dark rosewood Þ nish.
Line Power Consumption:
800 watts average, at maximum continu-
ous output. 8 watts at idle.
2,700 watts peak, time limited basis
Output Levels:
Greater than 116 dB peak SPL (includes
room gain) from 16 Hz to 100 Hz. Mea-
surement is one meter, anechoic.
A typical SunÞ re subwoofer can be
ex pect ed to ‘best’ its spec i Þ ed minimum
peak SPL by several decibels.
Total Harmonic Distortion
Typically less than 1/10 of the fun da -
men tal between 18 to 80 Hz.
Input Sensitivity for full
output:
250 mVrms from left input with volume
control at 0 dB, 60 mVrms volume con-
trol fully clockwise
*
0.75 Vrms from right input with volume
control at 0 dB, 200 mVrms volume
control fully clockwise
*
Input Impedance:
30 kΩ for Line-Level inputs
56 kΩ for Hi-Level inputs
40 kΩ for XLR input, each leg balanced
to ground
XLR Input
Pin 1 Ground
Pin 2 Positive
Pin 3 Negative
Driver: 12 inch
Extra large magnet and long throw
me chan i cal design yield very high
back-emf. The result is ex traor di nar i ly
high operating efÞ ciency – that is, more
acoustic output for each watt of input.
Internal System Gain:
50 dB from left input jack to speaker
with volume control at 0 dB, 62 dB with
control fully clockwise
*
40 dB from right input jack to speaker
with volume control at 0 dB, 52 dB with
control fully clockwise
*
*
The SunÞ re True Sub woof er utilizes
differential gain on the left and right
inputs to retain both L+R and L-R
information.
12 VDC Trigger Input
Input voltage range: 5 -18 VDC
Impedance: approx 600 Ω
(20 mA @ 12 V)
Removable terminal block, and one 1/8”
Mono minijack, tip positive.
