Appendix A - Technical Specifications
Type: 3-way studio reference with subwoofer (2.1 System), expandable to 5.1
Subwoofer Driver: 8 inch diameter, specially-developed curved-profile pulp
cone, high-temperature voice coil and damped closed cell foam surround -
designed for sub-frequency pressure levels with very high efficiency and
extremely low distortion
LF Driver: 4-inch dia.,magnetically-shielded with curved mineral-filled polypropylene
cone, high temperature voice coil and damped closed cell foam surround
HF Driver: 1-inch dia., magnetically-shielded; specially-shaped mylar dome

Crossover Frequencies: 2.9kHz and 140Hz
RMS SPL @ 1 meter: 105dB
Subwoofer Amplifier Power: 60W
Sat Amplifier Power: 27W (Five Sat Amplifiers)
Dynamic Range: >100dB
S/N Ratio: >100dB below full output, 20kHz bandwidth
Input Connectors: Six TRS balanced/unbalanced input connectors (L, R, SL,
SR, C & LFE)
Polarity: Positive signal at + input produces outward low-frequency cone displacement
Input Impedance: 20k ohms balanced, 10k ohms unbalanced
Input Sensitivity, Sat: Input 100 mV pink-noise produces 90dBA output
SPL @ 1meter w/ vol ctl at max setting
Input Sensitivity, LFE: input 50mV pink-noise produces 90dBA output SPL
@ 1meter w/ vol cntrl at max setting
Protection: RF interference, output current limiting, over temperature, turn
on/off transient, subsonic filter, external main fuse
Indicators: Green-Orange Power/Protection indicator (Back Panel). When
the power switch is switched to ON, the LED will glow “Green”. When the
Protection circuitry of power amplifiers is turned on , the LED will glow
“Orange.” At the same time, the output level will reduce 12dB.
