Chapter 3 Fast First-Time Setup Follow these instructions to get your 565E up-and-running as quickly as possible. The intent of this section is fast setup. Refer to later chapters for explanation of the 565E’s controls and functions. Connect the line-level signal source for Channel 1 to either the female XLR input jack (pin 2 hot) or the 1/4-in. -

(such as a processor or an amplifier) would go into terminal overload. The solution is to make soft signals softer, a.k.a. downward expansion. This is what the 565E’s down- ward expander does. When the signal level falls below the level set by the threshold control, the expander reduces its gain by the amount dictated by its expansion ratio. - Page 7 Ratio The compression ratio of the 565E determines how much the output changes for a change in the input. A linear amplifier (like a simple preamp) has a ratio of 1:1 because a change of 1 dB at its input results in a 1 dB change at its output.
- Page 8 VCA (voltage controlled amplifier) what to do. The 565E’s sidechain is routed through a TRS jack labeled “KEY INPUT”. This jack is located on the rear panel, and it provides both a send and return via the same jack. The sidechain connection affects all three processors in the 565E.
- Page 9 You can save time, and make life easier, by listening to the output of the equalizer (instead of the 565E’s output) that you’re using in the sidechain. Doing this allows you to hear the signal that will control the 565E, and perhaps to find the range that you wish to emphasize...

Generally, peak limiting is associated with short release times and compression, or leveling, is associated with longer release times. The 565E’s release circuitry has a unique dual-release time feature designed to make life easier. The dual-release feature makes the release time partially program-dependent, giving you the best of both worlds: fast release for short-duration peaks and a longer release time for longer- duration peaks. - Page 11 565E’s processing circuitry when it is set to YPASS YPASS the “IN” position, and places the 565E’s processing section in bypass when the switch is set to the “BYPASS” position. Note This is not a hard-wire bypass; the 565E will not pass signal unless the unit is powered and turned on.

Symetrix equipment inputs are designed to bridge the output of whatever device drives the input (i.e. to be greater than 10 times the actual source impedance). Symetrix equipment outputs are designed to drive 600-ohm or higher loads (600-ohm loads are an archaic practice that won’t go... -

2 to 200 times the output source impedance). Signal Levels The 565E is designed around studio/professional line levels: +4 dBu or 1.23 volts RMS. The unit is quiet enough to operate at lower signal levels such as those found in semi-pro or musical instru- ment (MI) equipment (-10 dBu or 300 millivolts). - Page 15 In an emergency (the show must go on), you can ground pin 3, but if you have the choice...leave it open. If you must ground pin 3, it is must be grounded at the 565E, rather than at the other end of the cable.
- Page 16 Then, route the aux send’s line-level output to the K NPUT of the 565E. Typically, signals such as the output signal of a keyboard or a drum machine are already at line-level, so these outputs could be connected directly to the K of the 565E.
- Page 17 To use the K as a sidechain insert point for external processing of the 565’s sidechain NPUT signal, connect the K jack’s tip (+) and sleeve (ground) to the input of the external pro- NPUT cessing device, and connect the K jack’s ring (+) and sleeve (ground) to the output of the NPUT external processing device.

Page 18: Chapter 8 Applications
Applications Chapter 8 Here are a few applications for which the 565E is an optimal processing tool. The following applications make one assumption: settings for the threshold control(s) are a function of each individual system’s actual operating level. Wherever specific threshold settings are mentioned, they are referenced to either a particular gain reduction level as indicated by the meter, or to a 0 dBu input level. - Page 19 By splitting the host signal, part of it can be used to tell the 565E when to take action and lower the background source by an amount determined by the threshold control.
- Page 20 Remember that you’re equalizing the signal to emphasize the sibilance, not to sound groovy. Let the 565E do that. (Do you have a recording where the cymbals drive you nuts?...Try the same technique on the overall mix.) Set the peak limiter threshold for 6 dB of gain reduction when Sam Screamer is on the system.

565E is a line level signal, not mic level. Check gain settings on downstream equipment. The system gain structure should be such that the 565E operates at or near unity gain. Is the input signal already noisy? -
