Important:
Phantom power
The wrong selection of microphone power may harm your microphone ! Always select the proper
setting on the mixer before connecting the microphone !
Use of Batteries
To change from battery to external power supply extract the dry cells from the battery case to
avoid damage. (Detailed information is available on page 10)
1. General description
Designed for sound for film and video, the SX-PR is a very compact and light weight mixer renowned for its high quality microphone pramplifiers and reliability.
The mixer is composed of one master module and a number of input modules. The number of input modules can easily be changed to upgrade the unit to next larger version. Each
input module provides two input channels which means the SX-PR 2 has one, the SX-PR 4 two and the SX-PR 6 3 modules.
Dual Mic /Line input Module
The inputs are electronically balanced (+ connected to pin 2 on the XLR) and are equipped with HF-filters.
Microphone powering is selectable between P12 and P48V (phantom) and T12 Volt (Tonader).
The gain control is a 12 step rotating commutator in the range from 0 to 78 dB. On request these 12-step commutators can be replaced by a contineous potentiometer.with a reduced
range, however, between 10 and 78 dB.
The overload (OVD) indicator LED lights up at 6 dB below distortion.
A switcheable high pass filter (80 Hz or 120 Hz) is on each channel.
The panorama potentiometer allows panoramic placement of the input signal between the stereo main channels. Switching to MONO the PAN control has no effect and the signal is
sent to both output channels at an equal level.
Mastermodule
The master module is equipped with two electronically balanced outputs on XLR connectors, one unbalanced input and a headphone output with volume control settable in 6 levels.
The power supply can be dry cells or NiCd batteries or an external source providing 6-12 Volt DC, 500 mA.
The level meter can be used to monitor the battery voltage periodically. An additional LED indicates the approach of reaching the lower limit of the working voltage.
The built in limiter operates on the output signal and can be channel linked for of stereo recording.
A small slate microiphone is integrated in the frontplate
A 1kHz generator can be switched to the outputs.
