Channel EQ
Choose between a channel equalizer with natural sound (-24 dB attenuation) or a flexible channel isolator with full cut.
Channel Equalizer
Attenuation / Boost: -24 dB / + 9 dB
Frequencies: 50Hz, 1kHz, 20kHz
Channel Isolator
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
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.
