The E520 Hyperion is a mono/stereo in, stereo out effects module.
Powered by a 480MHz ARM Cortex M7 CPU, the E520 has 64MB on on-board SDRAM for recording up to 6min of stereo audio at 48KHz sample rate. The LCD screen and optical encoder navigation uses the same 'shallow' menu scheme of our E352 and E370 modules, with the addition of 4 'soft keys' for selecting options without having to leave the main page.
The module uses a premium audio path not usually found in Eurorack. Crystal Semi CODECs, TI OPA-series op amps (in the audio sections) are used along with low-noise, dedicated LDO voltage regulators for a clean, full soundstage. Audio conversion uses 48KHz sample rate, 24bit resolution with a line or synth level setting.
They are based on the most versatile BBD (bucket brigade delay) chip out there: the MN3011. Thanks to this chip, the RS-650 offers both delay and reverb settings in one module. Flip the switch to quickly change between delay or reverb effect.
The MN3011 BBD was an intermediate stage between normal delay chips and digital reverb. It has multi-tapped outputs which are configured in a way that simulates multiple acoustic reflections with a non-overlapping pattern. This yields a semi-reverberant characteristic and produces a warm, dense and organic reverb sound.
In Echo mode the delay time can be set with the according potentiometer between 75 and 200 milliseconds and with control voltages, from 50 to 2000 ms. Beyond a delay time of 300 ms the internal clock frequency becomes audible which can be minimised by using a low-pass filter. Create a chorus effect by sending an LFO to the Delay Time CV Vary input. Adjust the speed and depth to taste! The intensity of the effect is voltage controlled thanks to the Dry/Wet CV input. This offers further creative possibilities.
The resonance parameter sets the number of repeats and can be considered as the feedback parameter. It goes up to self-oscillation which will work even without input signal. Try sending a trigger into the audio input!
All in all the RS-650 brings a great vintage and oldschool BBD sound to the table!
Black Corporation Deckard's Voice eurorack module is an entry level semi-modular synth for eurorack systems. Sharing the same paradigm and circuit as its bigger brother Deckard's Dream, trimmed down for eurorack and supplemented with the flexibility available only in a modular format.
The Koantenn is a versatile overdrive/resonant filter pedal with CV input. The Amplaer Red Elektrek is a stereo tube headphone amp with balanced dual mono 6.35mm jack outputs and 3.5mm stereo headphone output. Both use high quality components and are manufactured entirely in France.
