frequency band centers of the 131s and 231s are marked at 1/3rd of an octave intervals on ISO standard spacings, while the frequency band centers of the 215s are marked at 2/3rds of an octave intervals on ISO standard spacings.

Low Cut Enable Switch

The LOW-CUT switch inserts or removes the 12 dB per octave 50 Hz low-cut filter from the signal path. When the LOW-CUT switch is pushed in, the LOW-CUT filter is IN the audio path.

Section 3 - Connecting the EQ to Your System

The 2-Series Equalizers have balanced inputs and impedance balanced outputs that can be used with any balanced or unbalanced line-level device.

To connect the equalizer to your sound system refer to the following steps:

•Turn off all equipment before making connections.

•Mount equalizer in a standard-width rack.

Install the EQ in a rack with the rack screws provided. It can be mounted above or below anything that does not generate excessive heat. Ambient temperatures should not exceed 113° F (45°C) when equipment is in use. Although the unit’s chassis is shielded against radio frequency and electromagnetic interference, extremely high fields of RF and EMI should be avoided.

•Make audio connections via XLR or 1/4" TRS jacks (according to application needs).

Both types of connectors for the inputs and outputs can be used for balanced or unbalanced connections. The use of more than one connector at a time for the inputs could unbalance balanced lines, cause phase cancellation, short a conduc- tor to ground, or cause damage to other equipment connected to the equalizer. More than one output may be used simultaneously as long as the combined paral- lel load is greater than 2 kΩ.

•Select the operating range with the Boost/Cut range selection switch.

NOTE: Be sure to reduce audio levels at the power amplifiers when changing the setting of this switch as it may generate an audible transient.

•Apply power to the equalizer.

Connect the AC power cord to the AC power receptacle on the back of the equal- izer. Route the AC power cord to a convenient power outlet away from audio lines.
