FM Acoustics 115 mono block power amp
저가 잘 사용하고 있는 fm 115 모노 블럭을 소개 드리겠습니다.
가끔씩 아주 가끔식 fm 1811 파워엠프가 궁금하기도하나
허벅지를 바늘로 찌르고 있습니다.^^
아래는 스펙입니다.
최진혁 사장님! 참고만 하십시요^^
(115 배를 갈라본 사진이 흔들렸네요. 죄송합니다)

FM 115 MONO BLOCK POWER AMP.
Specifications
Minimum Power Output:
operating with music or continuous toneburst:
550 Wpeak into 8 Ohm
1000 Wpeak into 4 Ohm
1800 Wpeak into 2 Ohm
275 WRMS into 8 Ohm
500 WRMS into 4 Ohm
900 WRMS into 2 Ohm
Max. Output Voltage:
140 Vpp
Max. Output Current:
Unlimited repetitive peak output current. More than 35 A continuous.
No output or DC fuses,
absolutely no form of current-,
voltage- or any other kind of limiting.
Distortion:
0,005% THD, no higher order harmonics Bandwidth including Input Filter:
Less than 1 Hz to 60 kHz; if required, internally settable to any frequency
between 1 kHz and 60 kHz (Low-Pass)
and 1 Hz to 1 kHz (High-Pass).
Gain:
30.9dB
Risetime at Full Power -3db:
3 uS
Hum and Noise:
Minimal unweighted:
better than -100 dB (20Hz-20kHz).
Input:
Proprietary electronically balanced discrete enhanced class A circuitry, non-polarized,
floating ground, non-inverting or inverting mode. Optimal performance with either balanced
or unbalanced (single-ended) sources.
Unbalanced sources are automatically balanced right at the input of the FM 115.
Input Sensitivity:
1.2 V RMS for full output
Input Impedance:
At all level settings from balanced and unbalanced sources:
40 kOhm
Input Stage Common Mode Rejection:
100 dB typically, better than 95 dB at 50 Hz, even better at other frequencies.
Maximum Input Level:
+20 dBm (20Vpp)
Load Impedance:
No minimum impedance.
The amplifier is designed for 1 Ohm to 10’000 Ohm systems.
It can drive any speaker impedance (even below 1 Ohm)
with dynamic (music) signals without any limiting,
compression or other negative effects on the audio signal.
Despite this, the amplifier is fully protected against short circuits,
open circuits and all other adverse conditions via unique onboard circuitry
that continuously surveys all important parameters.
