Blk BLX is a Quad Linear/Exponential Voltage Controlled Amplifier / Voltage Controlled Mixer / Distortion module
Blk bLX is an Ultra Compact (6 hp) High Performance Quad Linear/Exponential VCA and Voltage Controlled Mixer at once.
It also benefits from the strange new technology: "Advanced Calibration Amplifier Block"-the effect that can be engaged by pressing ACAB button.
VCAs use High Performance chips and like all good quality VCAs they're dead silent in absence of CV signals, so no unwanted cross-talks, "bleed-through" offset voltages, etc.
All four VCAs have CV attenuators for their four channels, have two offset controls for the first two channels and two mini potentiometers to smoothly transit from linear (on the right) to exponential response (on the left) for the channels 1 and 2 (for the channels 3 and 4 this can be set via trimmers on the back of the module -by default they are set in linear mode). Leds are indicating the signals strengths.
Module performs also as VC mixer since the CV channels are connected in cascaded way so the outputs will send out the mix of previous channels if they're not patched individually. That way, for exemple, you'll have an entire mix of all four channels by using the forth output and if ACAB button is pressed it will be applied on the whole mix - or, if the channels are used individually, it will be applied only on the fourth channel.
CVs are "normaled" to offsets so even if no CV is present the attenuators will then act like level controls which transforms the module into an audio mixer *with higher gain impacting amplitude it'll produce clipping when near maximum, note that with pushing also the offsets to maximum this will result in hard clipping.
The module is DC coupled so it's convenient for both audio & cv use.
"And what happens when I press ACAB ?" Well, be aware: in difference of the clean mix achieved in normal use - once ACAB button pressed it will smash your drums into peaces and boost and distort your synth lines!
It works like on/off button but the intensity and the overall impact of the effect can be at some point controlled by the VCA controls- manually or by the use of CVs as it will act differently depending on gain-amplitude/level and type of signal (LFOs, envelopes/inverted envelopes for ex.will increase/decrease levels and therefore change the way how the mix will be overdriven) As said previously, with cv/offsets pushed to clipping, loud exponential mode this may lead to a reel mess-so be careful with your ears & speakers :)
*if you find it too loud/agressive & noisy for your taste you can attenuate it via small trimmer pot inside the module with a small screwdriver. It is possible to set it at the same level as VCA's output but the impact will then be limited.

Dispatch times
Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.
If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
