Input Gain Control: This control sets the signal level to the equalizer. It is capable of -12dB to +12dB of gain. Its effect is apparent by viewing the OUTPUT LEVEL BAR GRAPH.

EQ Bypass: This switch removes the graphic equalizer section from the signal path. (See Block diagram on Page

8.) The BYPASS switch does not, however, affect the INPUT GAIN, or LOW CUT filters. EQ Bypass LED: This red LED lights when the EQ is in bypass mode. Note that bypass mode only effects the

graphic equalizer section of the 12 Series EQs. The INPUT GAIN and and LOW CUT controls remain unaffected when the EQ is bypassed.

Boost/Cut Range Selection Switch and LEDs: This switch selects which of the two boost/cut ranges the equalizer will use, either ±6dB or ±15dB. The red LED lights when the ±15dB range is selected, and the yellow LED lights when the ±6dB range is selected. Note that the BOOST/CUT switch is slightly recessed. This is to prevent accidental activation of the switch, possibly causing damage to other sound system components.

Output Level Bar Graph: These four LEDs indicate output level of the equalizer. The red LED is 3dB below clipping and is marked as +18dBu. It monitors the level at the output of the equalizer after all other processing.

Clip LED: This LED lights whenever any internal signal level reaches 3dB below clipping which may occur when any of the following happen: 1) the input signal is “hotter” than +22dBu, 2) excessive gain is applied by the input gain control, or 3) excessive boost is applied using the frequency sliders.

Frequency Band Slider Controls: Each one of these slider potentiometers will boost or cut at its noted frequency by ±6dB or ±15dB, depending upon the position of the BOOST/CUT RANGE switch. When all the sliders are in the center detented position the output of the equalizer is flat. The frequency band centers of the 1231 are marked at 1/3rd of an octave intervals on ISO standard spacings, while the frequency band centers of the 1215 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 18dB/octave 40Hz Bessel low-cut filter from the signal path. When the LOW-CUT switch is pushed in, the LOW-CUT filter is IN the audio path.

CONNECTING THE EQ TO YOUR SYSTEM

The 12 Series Equalizers have balanced inputs and outputs that can be used with any balanced or unbalanced linelevel device. For more specific information about cabling possibilities, please refer to the section entitled Installation Considerations, Page 5.

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 EQs 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, barrier strip, or 1/4" TRS jacks (according to application needs)

All three 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 conductor 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 parallel load is greater than 600Ω.

• 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 equalizer. Route the AC power cord to a convenient power outlet away from audio lines. The unit may be turned on and off from the rear panel

power switch or a master equipment power switch. Since the 12 Series Equalizers consume a relatively small amount of power, the units may be left on continuously.

REAR PANEL DESCRIPTIONS

Rear Panels

1231 - dual channel 31 band graphic equalizer

1215 - dual channel 15 band graphic equalizer

Power Switch: Switches the power on and off. Always make audio connections with the power switch in the OFF position.

Power Cord Receptacle: Connects AC power to the equalizer. Output Connectors: Three types of output connectors are provided for output connections: male XLR type con-

nectors, 1/4" tip-ring-sleeve phone jack connectors and a barrier strip. Input Connectors: Three types of input connectors are provided for input connections: female locking XLR type

connectors, 1/4" tip-ring-sleeve phone jack connectors, and a barrier strip. The maximum input level that the equalizer can accept is +22dBu (ref: 0.775Vrms).

Chassis Ground Lift Strap: By removing the jumper connecting the two screws on the barrier strip, the chassis ground is separated from the circuit ground of the equalizer. This is sometimes necessary to prevent “ground loops” in a sound system. When lifting the ground strap, you must make a connection from the circuit ground ( ) terminal to some other ground point in your audio system in order for the equalizer to function properly.

INSTALLATION CONSIDERATIONS

Hookups and Cabling: The 12 Series Equalizers are designed for nominal +4dBu levels. The equalizers can be used with either balanced or unbalanced sources, and the outputs can be used with either balanced or unbalanced loads, provided the proper cabling is used.

A balanced line is defined as two-conductor shielded cable with the two center conductors carrying the same signal but of opposite polarity when referenced to ground. An unbalanced line is generally a single-conductor shielded cable with the center conductor carrying the signal and the shield at ground potential.

Input Cable Configurations: The equalizer has an input impedance of 40kΩ balanced and 20kΩ unbalanced. This makes the 12 Series Equalizers’ audio inputs suitable for use with virtually any low source impedance (under 2kΩ).

Output Cable Configurations: The equalizer’s output is capable of driving a 600Ω load to +18dBu. For maximum hum rejection with a balanced source, avoid common grounding at the equalizer’s inputs and outputs. Most balanced (3-conductor) cables have the shield connected at both ends. This can result in ground loops which cause hum. If hum persists try disconnecting the shield on one or more of the cables in the system, preferably at the input of a device, not at the output.

OPERATION AND APPLICATION NOTES

The dbx 12 Series Graphic Equalizers are useful audio signal processing tools in situations where precise frequency control is required across the audible frequency spectrum.

When used with an audio spectrum analyzer the EQs can tune any acoustical environment -- from the studio to the concert hall -- to stop ringing, increase clarity, and flatten the overall frequency response of the environment. A real-time spectrum analyzer or other types of audio environment analyzers are very useful in determining the amount of equalization needed.

Insert the graphic equalizer between the signal source (usually a mixer) and the power amplifiers (or the crossover if there is one). Adjust the level and equalization as required to yield the desired system response. The long throw faders of the EQs allow very precise settings of the equalization for accurate equalization curves.

For optimum signal-to-noise response, the gain structure of the sound system must be properly set up. Each component of the sound system should be set at its nominal operating level, starting with the first element in the system, usually a mixing console. Each element should be run at its nominal operating level in order to take advantage of the maximum signal-to-noise properties of that element. Loudspeaker amplifiers, as the last element in the chain, should be set only as loud as necessary, in order to avoid inducing unnecessary noise into the system.
