Rane check by Paul White. If this unit doesn't solve youn EQ problems — you've got problems!

This compact rack package from Rane is essentially five parametric equalisers connected in cascade, each one tailored to cover a specific portion of the audio band. Unlike the more common sweep equalisers, the bandwidth of each filter section is independently variable and may be set as narrow as ¹/₃₀ of an octave, with the exception of the lowest band which has a minimum width of ¹/₇ of an octave. Each filter section may be switched in or out of the circuit as required and an overload LED indicates if clipping is imminent anywhere along the signal path.

The equaliser may be used to cut or boost any frequencies within its range. The maximum amount of control available is 15dB of boost or 20dB of cut per section. Bands one and five incorporate a pull switch built into the bandwidth control and this changes the filter from bandpass mode to give a shelving response.

"One way to consider this unit is as a 5-band graphic equaliser where the frequency and bandwidth of each section is under user control..."

In order to be fully compatible with professional installations, the Rane PE15 features a balanced input with a choice of balanced or unbalanced output, a choice of jack or XLR connector being available in both cases.

A master level control and bypass switch completes the compliment of controls and a green LED cunningly indicates the presence of any signal in excess of -20dBm.

Conclusions

There is no doubt that this is a well designed and extremely flexible equaliser but like all parametrics, it can take a long time to set up properly. The fact that you can switch equaliser sections out of circuit is the saving grace in this instance. If all the equalisers were constantly in the signal path, you wouldn't stand a cat in hell's chance of coming up with the optimum settings.

One way to consider this unit is as a 5-band graphic equaliser where the frequency and bandwidth of each section is under user control, and indeed, this type of device is occasionally referred to as a paragraphic equaliser - though it really should have sliders to qualify for this title.

"There is no doubt that this is a well designed and extremely flexible equaliser but like all parametrics, it can take a long time to set up properly."

The signal present LED is a good idea, especially if you're in the habit of losing signals somewhere in your patchbay and not knowing where they've gone, and the option of switching the end filters to shelving operation is a sensible inclusion. In a sound reinforcement situation, this device should be a great aid in keeping feedback at bay and in the studio, its corrective and creative possibilities extend far beyond those of the equaliser section of your mixer or even a graphic.

Like any equaliser, the Rane should be used sparingly but it really is capable of doing anything that you might reasonably require of it.
