The amplifier provides outputs for 4-ohm, 8-ohm and 16-ohm loudspeakers, plus a 70-volt line output for distribution systems. In addition to the high-impedance input, the amplifier has an octal socket to accept a line-isolation transformer. A selectable high pass filter is included for use in speech systems. Cut-off frequency of the filter is 300 Hz. The 1593C is capable of operation from a 120V or 240V ac source or a negative grounded 28V dc source, and features silent, automatic transfer to
The 1590E provides 200 watts of power at less than 1% total harmonic distortion (THD) from 50 Hz to 12 kHz, and has a frequency response of -1 dB from 20 Hz to 20 kHz at one watt output. Output transformer taps provide connections for 70.7. 100. 140 and 200 volt line distribution systems. The 1590E features silicon solid-state circuitry, a switchable high-pass filter for use in speech systems, input connections for high impedance devices and for 150/600 ohm or 15,000 ohm balanced inputs, fail-s
The sound card’s documentation should help you determine which outputs to use with your speaker system. 1. Make sure the power to your computer is turned off. 2. Locate the lime green 3.5 mm stereo cable provided with your speaker system. 3. Connect one end of the lime green 3.5 mm stereo cable to the matching jack on the back of the right satellite, and the other end to the lime green output labeled “FRONT” on your sound card. Portable Audio Devices (MP3, Portable CD Players, etc.) 1. Make sure

For example, Channel 1 and Channel 2 together can provide stereo, mono, or bridged operation, completely independent of Channels 3-4 or Channels 5-6 settings. 7.4 50Hz Low Cut Switch Each pair of channels has a 50Hz second order (12 dB per octave) low-cut filter option which is applied to both channels within the pair. When the switch is pressed, the audio signal is -3dB at 50Hz, -15dB at 25 Hz, -27dB at 12.5Hz, etc. 8 Operating Manual 6125A and 4200A Multi-Channel Power Amplifier 7.5 Input Leve
