Denon PMA 250 SE Amplifier
November 18, 2008
The sole function of amplifiers is to offer amplification to the sound signals that is it
strengthens the audio signals making it audible and effective. Many models and brands of amplifiers are available in the market but very few offers enhanced performance rate. Among that few names one is Denon PMA 250 SE Amplifier which caters to all the amplification requirements. Though compact in looks it is very efficient in operation. All the controls are easy to use and enhanced features makes it a better product.
The total RMS is calculated as 30 watts which results in power packed performance. This is a table top unit. The amplifier recording is calculated as A/R 20 with a power of 35Watts. Output power is calculated as 2 x 30W at 8 Ohms of 20-20kHz frequency. The output power differs at 4 Ohms and 1 kHz that is 2 x 50Watts.
Total harmonic distortions are 0.08% 1 kHz or 3dB noise ratio. Frequency response of the unit is 10Hz – 80 kHz that is for +0dB, -3dB @ 1W. Details of the line inputs are 150mV/47kOhms. Signal to the noise ratio of this unit is 98dB. Various tone controls are facilitated in the unit that is 100Hz ± 8dB fro bass and 10 kHz ± 8dB for treble and thereby you can amplify signals according to their audio nature.
Power consumed by this unit is 120W and requires a voltage of 230V AC for its functioning. The frequency is calculated as 50Hz. All together the unit can be considered as an energy efficient one.
This table top unit has a dimension of 434 x 115 x 286mm and weight of 5.5kg, which makes it convenient in operation. Denon PMA 250 SE 30W Amplifier offers unbeatable operation and out stands rest of the similar products in the market.
