| With the PAN05, two microphone signals can be mixed down to one. Since decoupling occurs via the balanced resistor network, the PAN05 also lets phantom power "pass through“, useful for condenser microphones. However, due to the difference in sound and signal level, mixing dynamic and condenser mics should be avoided. Best results will be achieved using two identical mics.

- Load impedance >200 Ω
- Symmetrically decoupled through resistors
- Total ohmic value: 200 ohms
- Typical attenuation: 6 dB
- Housing: metal casing 110 x 73 x 42 mm

Cable Tester ACT-100
The Alphaton active remote cable tester can be used for testing either normal short
cables or long ones, especially mufticores, wkh connectors not being accessible at
one time. The tester is especially suded for fixed installations where cables can not
be tested with a standard type cable tester or Ohm meter. Either symmetric and
unsymmetric cables can be tested.
“Cold" solderings and junction resistances are displayed by color or luminosity changes
in three color LED Display. The imprinted fault table incorporates alt important fault
conditions, indeed not all possible ones due to their reiatively large number. In case the
display is in a state which cannot be found on the imprinted table, it can be looked up in
the user's manual. In any case, however, the cabie is in aquite unusable state and should
be repaired or replaced.The Alphaton cable tester has a SEND and a REMOTE section.
The REMOTE sectionconsistsof two recessed mounted XLR type male or female connector
and a stereo phone jack at the right hand side of the tester. Additionally, a separate REMOTE
plug is delivered togetherwith the active remote cable tester for testing long cables in fixed
installations.
