The Monster EQ ML-116 is an advanced 2-channel equalizer to meet the versatility demands of professional recording and mastering engineers. Special analog design techniques has been used to obtain a precise control of the sound structure down to the minimum details.

The Monster EQ ML-116 is an advanced 2-channel equalizer to meet the versatility demands of professional recording and mastering engineers.

The ML-116 features HI and LO cut filters and a 5 band parametric equalizer section including high & low shelving filters. This advanced set of tools for the manipulation of the frequency spectrum allow for unique filtering designs so for a perfect tuning of the structure of the sound down to the smallest detail. The ML-116 is based on Livio Agentini’ s patented single-stage parallel filters. This innovative phase coherent EQ design offers the lowest distortion/noise specifications, not available on similar units on the market.

The equalizer architecture provides a -6dB/+6dB rotary switch controlling the input level, a 50 KHz HI-cut filter and a LO-cut filter with 6 selectable cut-off frequencies.

The filtering section offers low and high Baxandall shelving filters with 3 different shelving slopes selected by a switch. The gain is controlled in the -10dB/+10dB by pots. A special button labeled “Range” halves the pot’s dB intervention range, increasing its resolution for super fine-tuning of the filter parameters. When this button is pressed, the pot’s entire 270° rotation is spread on a -5dB/+5dB range (rather than the default -10dB/+10dB range).

The Monster EQ provides 5 single-stage fully parametric bands. Each band has a Q control and a switchable CUT/OFF/BOOST function that allows the use of the full knob rotation for the Emphasis/De-Emphasis control in the 0/10 dB range. In the parametric section the “Range” button is used for finer adjustments of the gain spreading the 0/+5 dB range on the full 270° potentiometer rotation angle. The F x 2 switches are used to multiply by 2 the frequency bands.

The Monster EQ is an innovative and uniquely flexible design equalizer, ready to take its place in any high profile recording or mastering

    ML-116 Key-Technologies

  • LARGE BANDWIDTH (LBW)

    Large Bandwidth (LB) means a very fast transient response able to represent the original sound with the maximum temporal resolution. LB is required to improve the perception of a “real sound” and to represent the details of the original sound.

  • PERFECT SQUARE WAVE (PSW)

    Large bandwidth plus very low total harmonic distortion means a perfect square wave reproduction.

  • ULTRA LOW NOISE (ULN)

    Ultra Low Noise (ULN) active and passive components and ULN design techniques. This requirement is especially important when the audio bandwidth is large as in the case of ARREL Audio products.

  • VERY HIGH DYNAMIC RANGE (VHDR)

    Very High Dynamic Range (VHDR) means that the saturation probability of the output stages is extremely low. This is obtained by using special rail to rail circuits and by increasing the power supply voltage of the analog circuits.

  • ELECTROMECHANICAL FAULT TOLERANCE (EFT)

    Electromechanical tolerance means that electromechanical components are doubled in every situation in which maximum reliability it is important due to a frequent use (switches, push buttons, potentiometers).

  • THROUGH-HOLE TECHNOLOGY (THT)

    Through Hole technology means the maximum reliability in terms of thermal and mechanical stresses especially for connectors and electromechanical components.

  • LOW PHASE DISTORTION EQ (LPHD EQ)

    Special patented circuits guarantees very low phase distortion in ARREL equalizers and filters.
