VU Meters

VU Meters can be used al-

ternatively for each meter. 

In  addition,  LED  and  VU 

meters  can  be  mixed  in 

any way. The VU-meters 

are  brand  Sifam.  Theyfit 

into  two  channel  slots. 

Two  meters  can  be  in-

stalled,  one  above  each 

other.  The  meters  have 

an active rectifier circuit with level adjustment. The attack and release time is 

300 ms. The lead can be adjusted to any desired value.

RTW-Peakmeter 

Different versions of 200 segment plasma bar-graph meters, brand RTW, Ger-

many can be installed. These meters can be used for each sour-

ce, alternatively to LED-PPM‘s and VU Meters. The Series 1000 

devices can be mounted vertically and fit into the module grid. 

This series is best choice for use with the BC4 system. 

Devices in standard cassette housings 190 x 40 mm (type 1113, 

1115 or 1119) must be installed horizontally. A maximum of 2 

devices, one above each other can be installed. Special front 

panels are available for both, the Series 1000 and Series 1100 

units. Phase correlation meters are available as well.

The pictures on this page show some of the available versions. 

Please check the RTW website (www.rtw.de) for details about 

the different versions. 

All RTW devices need special front panels and special wiring. 

These meters do not fit into the standard meter frameboards. 

The series 1000 can be adapted to the frame PCB‘s while the 

series 1100 devices require a frame slot where no PBC‘s are 

installed.  

Loudspeakers

For use as PFL and talkback loudspeaker we offer an active mini speaker that 

fits into the meter bridge. One or two speakers can be used in a console. Th-

ey are normally driven by the mini speaker output and can be used in stereo 

if two system are installed.The loudspeakers are equipped with 

coax wide-band systems. The 8 watts power amplifier is supplied 

from a separate voltage that is available with all power supply 

units. The speaker fits into 4 meter bridge slots.

 

Additional devices

The  picture  shows 

a  TFT  multifunc-

tion  display,  RTW 

Portamonitor. Such 

devices can be inte-

grated into the me-

terbridge with spe-

cial made front pa-

nels if they fit into 

the  height  of  the 

top plate (145 mm) 

and if the depth is 

not more than 100 

mm. Please ask for 

details.
