11 English – DYNAMICS PROCESSOR Dynamic range is the difference between the loudest and quietest levels of an audio signal. Controlling dynamic range plays an important role in good audio quality . Using the DP1 1EQ Dynamics Processor , you can control the dynamics of a sound system to improve audio quality . Y ou can use the gate or expander to [...]

12 English – Dynamics Parameters The edit boxes are used to adjust the parameters of each dynamics process. This section gives general definitions of the parameters. See Dynamics Processes for more specific information. THRESHOLD. The Threshold parameter determines the input level at which dynamics processing begins. For the gate and the expander[...]

13 English – Dynamics Processes Gate Definition: A gate mutes an input signal when it drops below a user defined threshold. Every sound system has a certain amount of noise or hiss. Some of this noise is in the background (the hissing of air conditioners), and some may be caused by electrical sources affecting the equipment (electromagnetic hum c[...]

14 English – AGC Leveler Definition: The AGC leveler (AGC stands for Automatic Gain Control) automatically lowers or raises the signal level for sounds of varying loudness in order to create a more consistent volume. Application: The leveler can be used for podium and lectern microphones, where it is desirable to maintain a constant volume level [...]

15 English – Compressor Definiton: A compressor reduces the dynamic level of an input audio signal by an amount determined by the ratio setting (usually less than 10:1). T ypically , a compressor has a slower reaction time than a limiter . Application: Compression can be used in order to scale a signal with a wide dynamic range to audio equipment[...]

16 English – No Overshoot Peak Limiter Definition: The no overshoot peak limiter has the ratio fixed at infinity to one ( ∞ :1), uses fast time constants and inserts 1 millisecond signal path delay , allowing the gain reduction to act instantaneously , without audible clipping artifacts, once the input level goes above the threshold. With the n[...]

17 English – P ARAMETRIC EQUALIZER The DP1 1EQ also contains two parametric equalizers, with up to 1 1 parametric filters possible. These equalizers can be used for tuning out feedback or other anomalies in the frequency response of the acoustics of a room or sound system. There are high- and low-frequency rolloff/shelf filters, and parametric fi[...]

18 English – Setting and Adjusting Parametric Filters Point and click on a filter . It will change colors to show that it is selected. Then, drag the filter by the center to the desired frequency and gain. A parametric filter can be used to cut or boost over a desired bandwidth. Notice that each filter dot also has wings with two smaller dots. dr[...]

19 English – Response Graph This section describes how to use the Response Graph, which displays the frequency response for the DP1 1EQ. Snapshots A helpful feature of the response graph is the ability to take snapshots of a frequency response curve. A snapshot allows you to view a trace of the original response curve while making changes. This i[...]

20 English – IN/OUT Meters and Output Control The IN and OUT level meters located next to the response curve graph display the levels of the input and output for the selected equalizer in dB. When the levels indicate OVR (over), the unit is clipping. This is a useful tool for observing net gain for the equalization settings. T o compensate, you c[...]

21 English – DELA Y There are some potential problems with the arrival of sound in systems utilizing multiple loudspeakers. The DP1 1EQ Delay is designed to solve two of these problems: remote speaker alignment and phase cancellation.
