Wohler AMP1A Plus Dual Source Stereo Analog Audio Monitor
With audio fidelity as good as in-rack audio monitoring gets, the AMP1A Plus provides two stereo, balanced analog XLR input sets with controls for volume, left/right balance, and selecting which input pair to listen to. Sound is reproduced with a pair of high-bandwidth loudspeakers, and two woofers, as well as a 1/4" auto-muting headphone jack. The loudspeakers and woofers have their own fully independent amplifiers and circuits for maximum output performance without distortion.
All AMP1 Series models contain high performance speakers driven by three power amplifiers; two amplifier/driver combinations handle midrange and high frequency information in the left and right (stereo) speaker channels, while the third amplifier channel sums the left and right channel information below the 500 Hz crossover point in the woofer (bass) speaker(s). Note that the woofer channel is not a dedicated LFE or center channel.
The 1U rack size AMP1 Series products are configured with two speakers (left and right) to reproduce mid- and high-range audio frequencies (in stereo), but feature two woofer speakers to reproduce the summed (combined) low-range audio frequencies from the left and right speaker input channels. It should be noted that both woofer speakers, which are wired in series, are driven from one woofer speaker channel, and are not stereo. See the simplified diagram in the product specifications or user manual for a block diagram of the AMP1 Series audio amplifier/speaker configuration.
