The OLHO-2R is an analog 2-channel rotary DJ mixer, hand-built in Leipzig, Germany. Its 100% analog signal path is designed for ultra-low noise and minimal distortion – so your music sounds the way it was meant to.

ALPS potentiometers, Neutrik connectors, a large VU meter and a housing of CNC-milled European oak give it a feel that lasts for decades. Every mixer is built to order: choose channel EQ or isolator, center detents, an optional Innofader crossfader and the color of the front panel.

Features a master isolator (24 dB/octave, true bypass), send/return as well as booth and record outputs. Hard case and 2-year warranty included.

Channel EQ

Choose between a channel equalizer with natural sound (-24 dB attenuation) or a flexible channel isolator with full cut.

Channel Equalizer
Frequency response of the OLHO-2R rotary mixer channel EQ (-20 dB to +9 dB)

Attenuation / Boost: -24 dB / + 9 dB
Frequencies: 50Hz, 1kHz, 20kHz

Channel Isolator
Frequency response of the OLHO-2R rotary mixer channel isolator (-∞ dB to +9 dB)

Attenuation / Boost: -∞ dB / + 9 dB
Crossover Frequencies: 230 Hz, 4.5 kHz
Master ISO

The master isolator uses powerful 4-pole filters with a slope of 24 dB per octave to completely isolate frequencies for creative transitions or targeted dynamics. For maximum sonic fidelity, the circuit can be completely bypassed via a relay-controlled true bypass. As with the channel EQ, you can also choose whether the controls have tactile center detents or not.

4-pole isolator (24 dB / Octave)
Attenuation / Boost: -∞ dB / + 9 dB
Crossover Frequencies: 320 Hz, 3.2 kHz
True bypass switched by relay
Frequency response of the OLHO-2R master isolator: low, mid and high bands with boost and cut
Crossfader

The OLHO-2R complements the classic rotary controls with a maintenance-free Innofader mini pro, which enables rapid cuts via VCA technology outside the signal path. The crossfader curve can be switched between "cut" and "fade" and can even be internally adjusted to a cut-in of just 1 mm. Thanks to capacitive non-contact technology, the system is extremely durable and ideal for precise cutting and scratching.
