Ashly FTX-1501 User Manual 2

FTX-1501

The power amplifier, being of two channels, shall deliver a mini­mum power of 185 watts RMS per channel into 8 ohm loads and
275 watts RMS per channel into 4 ohm loads, or 275 watts per
channel into 2 ohm loads with both channels operating. When
switched into bridged-mono mode, the amplifier it shall deliver at
least 370 watts into a 16 ohm load, and 550 watts RMS into an 8
ohm load. The amplifier shall be immune to damage from shorted,
open, or mismatched loads. The amplifier shall have a gain of 29
dB +/- .2dB per channel and an input sensitivity of 1.3 Volts +/­2% for full rated output. Frequency response shall be 20Hz to
20kHz +/- .2dB. It shall be stable into any load, including pure
capacitors and inductors. Hum and noise shall be at least 100dB
below full output and SMPTE intermodulation distortion shall be
less than .01% at full output. The amplifier shall have rear panel
switching for parallel mono and bridging modes and rear mounted
level controls. The inputs shall be of balanced bridging type with
barrier strip, 1/4 phone jacks, and female XLR connectors. A
three-color L.E.D type indicator shall be employed to show the
power level of each channel and self contained forced air cooling

shall be used. Each channel shall have a PROTECT LED which
indicates an open relay due to short-circuit, ultrasonic, DC, or turn­on delay. The power output devices shall be of the Lateral MOS­FET type.

The amplifier shall weigh 41lbs net and mount in a standard 19
inch rack using two spaces (3.5 high). The power requirement shall
be 110-125VAC, 50-60-Hz. The power amplifier shall be an Ashly
FTX-1501.
