Page 9: Installation
Using the RMK 502 Rack mount kit The RMK 502 Rack mount kit allows the PM 502 to be securely placed into a 19 inch rack, desk or table without covering the ventilation slots. When installing the PM 502 into a rack, please ensure sufficient ventilation. -
Page 10: Connection
Please, do not connect E-guitars or E-basses with passive, high impedance outputs directly to a MIC/LINE input. The MIC/LINE inputs of the PM 502, as with the line level inputs of mixers from other manufacturers, are designed for the connection of the relatively low source impedance of electronic instruments. -

Page 17: Speaker Processing (Lpn)
Table 6.1: Amplifier routing Speaker processing (LPN) The power amplifier channels of the PM 502 incorporate Low-Pass-Notch filters (LPN) exclusively designed by DYNACORD. The LPN filter corrects the frequency and phase response of the connected loudspeakers. This effect can not be achieved using equalizers or „Bass- Boosters“, because the LPN filter mainly optimizes the transient response of the connected... -

Table 6.4: Locking levels (- = available, X = locked) Microphone processing (TALK OVER) The integrated ducker of the PM 502 reduces the level of the signals at the STEREO inputs whenever a signal is present at the MIC/LINE inputs (above the THRESHOLD level). If there is no MIC/LINE signal present the STEREO signal automatically returns to its preset level. -

S/N-ratio and provides you with the full bandwidth of the PM 502’s outstanding sound capabilities. The following gain setting instruction is to be used as a guide to help achieve a good signal input level: Set the MASTER volume controls to their minimum values (counterclockwise). - Page 21 The peak indicator plays a key role when setting input levels. The PK (peak) LED on the PM 502 provides a visual indication of the risk of distortion before you hear it through the connected speaker systems. The peak indicator checks the signal level pre and post of the channel’s VOLUME control and indicates the maximum of both levels.

OUTPUT SETTINGS menu, please refer to section Menu, page 26. Below the LIM indicator, the PM 502 offers a 3-segment LED chain for visual monitoring of the output level of the signal. The meter’s 0 dB mark is referenced to a 0 dBu output signal at the mixer output. -
Page 25: Equalizer
Engage the MUTE switch to mute all MIC/LINE input signals. Equalizer The PM 502 employs a 7-band stereo graphic equalizer (GEQ). Seven frequency bands offering 10 dB gain/reduction and a quality of Q = 1.5 allow the shaping of the overall sound to meet your personal preferences or to optimally match it to the acoustic conditions of different locations. -
