The ARREL Audio ER-140 SUMMUTE Muting Summing Unit has been conceived to offer to the EURORACK Synthesizer technology the superior audio performance of the ARREL audio professional products. The ER-140 is characterized by high reliability, rugged design, outstanding audio quality, versatility and ease of use typical of the tradition of ARREL Audio products.
ER-140 is a passive muting unit working on 8 channels, red/green leds indicates the on/off muting, the push buttons are high quality devices used for our professional audio products. The muting circuit is passive so you can mute both audio signals and control voltages (CV).
Moreover the ER-140 SUMMUTE works as a DC coupled audio summing unit on blocks of 4 channels. Being the summing circuits DC coupled, both CV and audio signal can be summed.
Channel 1 through 4 can be summed into the SUM 1-4 output, the same for the block including channel 5-8. Every summing block is equipped with an output gain in the range (-70 dB, +10 dB) and a peak led.
Due the variable amplification of the summing unit and to the DC coupling, the ER-140 can be used as a C.V. translator.
The peak led start to be active when the signal is about 3 dB below the maximum output signal level.
