Frequently Asked Questions
- What is the continuous power output of the amplifier?
The amplifier produces a continuous power output of 36 W + 36 W such that the load impedance is 8 ohm.
- What is the frequency response of the amplifier?
For the PHONO RIAA input, the band width is in the range of 20Hz-20kHz with a maximum ±0.5dB.
- How is the signal-to-noise ratio for the PHONO MM input?
The S/N ratio is 80dB for a 5.0 mV input.
- What is the measured effective minimum signal strength of FM radio?
This signal is acceptable for radio if the strength of the incoming signal is above 1.0 µV or 11.2 decibels.
- How to consider the form factor of device?
Dimensional values that have metric measurements in milliliters include 434 mm x 112 mm x 400 mm. The given values correspond to 17-3/32", 4-13/32" H and 15-3/4" D.
- Does the device need foreign voltage input?
During United Kingdom’s 240 V 50 Hz power supply or Europe’s 220 V 50 Hz power supply, the device works correctly.
- What is the weight of the tuner amplifier?
The quantitative bounds for the weight of tuner amplifier would be 7.5 kg or 16 lbs 4 oz.
