About the MRC EQ LIMITED

The MRC EQ LIMITED is the EQLimit sound level limiter-controller by MRC Audio, a Madrid-based manufacturer of recording sound limiters since 1991. It measures level with up to two microphones and limits the signal globally or by frequency, without abrupt cuts in the music, while logging all activity. It is aimed at anyone who must keep a music activity below a maximum sound level. Renting the MRC EQ LIMITED in Madrid and throughout Spain saves buying a unit for a specific date: ask us for availability and a quote.

What it is rented for

It is used for music activities in venues and spaces where the room level must not exceed a set threshold: the unit compares the signal with levels programmed by time and date and is designed so that only the level is limited, not the sound quality. With two microphones it can control two zones of the same venue, and the third-octave EQ matches it to the room's insulation curve. If you also need to measure the level, it could be paired with a sound level meter from our catalogue, such as the NTI XL2 or Dateq SPL-D2 MKII.

Key specs

• Limits the audio spectrum globally or by equalising the control signal with 12 third-octave filters (63 Hz to 8 kHz) to match the venue's insulation curve.
• Two microphone inputs (Type 2-equivalent microphones) to measure at two points or zones, with simultaneous SPL and Leq logging and A, C or 'Bass' weighting per channel.
• The control source can be the microphone or the line signal; it keeps limiting even if the input rises by more than 60 dB and remembers the last attenuation after a pause in the music.
• Balanced audio inputs and outputs up to +20 dBv, plus a built-in pink noise generator for automatic initial calibration.
• 3 time slots with different levels for each day of the week and 10 special periods; level change for open or closed door and an auxiliary input to give priority to fire alarm messages.
• Over 6 months of time- and date-stamped activity stored in non-volatile memory, 3 alarm types (level, microphone disconnected and efficiency) and reports exportable to PDF, Excel, Word or XML.
• Front-panel USB, RS232 (DB9 for a GPRS/GSM modem) and optional Ethernet; settings protected by a password through the manufacturer's SCL software, with sealable rear connections.

Frequently asked questions

How much does it cost to rent the MRC EQ LIMITED?

The rental price is €60 excluding VAT. Tell us your dates and location, in Madrid or anywhere in Spain, and we will confirm availability and send a quote by email (info@peaksound.es) or WhatsApp (+34 636 410 986). Ask what is included when you request it.

Who sets the limiter's levels?

According to MRC Audio, EQLimit settings can only be changed with its SCL software, which requires a licence granted to authorised installers or control authorities, plus a password on the unit that prevents unauthorised tampering. Tell us about your case when requesting a quote.

Does it limit from the microphone or from the line signal?

Either: you choose the microphone or the line signal as the control source, globally or by frequency. According to the manufacturer, controlling from the line signal prevents voices or shouting from influencing how the music is limited.
