DITOS ★ Transformer-Coupled Balanced Output Board for CompIQ Stella Pro Compressor Pedal


In stock


Built to order, 4-6 workdays

SKU: DITOS Categories: ,


If you are looking for the convenience of having a high-end analog audio compressor and a transformer output in a box, we offer one of the most compact and performant dynamics processor that you can find. The optional DITOS board is really complementary to the superbly transparent Blackmer® VCA’s main output on the CompIQ Stella Pro Compressor.

Bass Player A super-clean, studio quality second output to send to a desk or soundcard provides another ‘They’ve thought of everything’ moment.

Coupled in series with Stella’s main circuit, the DITOS transformer balanced output is filled with a warm richness that is excellent for live playing, instrument tracking, or for tone-conditioning of any electric instrument — bass, guitar, acoustic guitar, violins, keyboards, synths, and even vocals or anything else, really, with an appropriate preamp. The DITOS board comes pre-installed when ordered along with the CompIQ Stella compressor.

Making the CompIQ Stella Pro Compressor even more powerful

The DITOS MK2 transformer-coupled balanced output is suitable for direct recording, or for sending the signal to a mixing console. It can also be used as an unbalanced transformer-isolated floating output to send the signal to another pedal or an amplifier. This brings a new and warm voice to the main dynamic audio processing. When Stella is in bypass, the signal still passes the DITOS circuit, so this may account for an active bypass (as opposed to the main output which will be true bypassed).

The unbalanced main output and the transformer-balanced output may be used at the same time, they are both in-phase.

Ground-lift jumpers are available internally for dealing with potential ground-loop noise issues. The Ground Lift Jumper on the Stella board connects the chassis to the circuit ground carrying the negative power. The Chassis Lift Jumper on the DITOS board connects the chassis to the Sleeve in its output connector (equivalent to Pin 1 on an XLR connector). They both are ON by default (jumper contacts closed) which means the DITOS output is set by default for use with a balanced cable — a standard balanced type of connection to a mixing console input or the input of a recording interface. The operation manual has detailed information on how the balanced and unbalanced floating connections can be used and how these jumpers may help.

The DITOS board comes pre-installed if ordered along with the CompIQ Stella and it removes the functionality of powering the pedal with a 9V battery by taking up its space. If ordered separately, you must drill your Stella’s aluminum enclosure yourself for the 1/4″ TRS output connector. This connector is positioned higher than the input connector in the pedal to allow overlapping of the cables one on top of the other.

The DITOS board comes prepared for simple interconnection with CompIQ Stella mainboards manufactured after September 2021. However, the DITOS is also backward compatible with older versions.

The DITOS transformer output works exquisitely well to complement the Burr-Brown signal conditioning in the main circuit. The tone is filled with natural warmth, rendering tight and punchy lows, enhanced low-mids, and warm-ringing highs. The audio transformer was intensively tested and selected for minimal distortion, and almost flat frequency response, and it will only slightly saturate the very Lows at high signal levels. The transformer is driven by one of the highest performance, low noise, low distortion, and most pristine-sounding balanced line drivers out there.

The DITOS is truly a studio-grade transformer-coupled output that makes the Stella Pro Compressor a very powerful analog-audio dynamic processor in a very compact package.
