These balanced inputs may be unbalanced if desired. Either pin 2 or 3 may be tied to ground (pin 1) to unbalance the inputs of the Mjr Mixer. Note: The AES standard for unbalancing an XLR connector is to tie pin 3 to ground (pin 1).
In the interest of keeping the Mjr Mixer design simple and up to date with today’s technology, we have not offered “12T” or “AB” microphone powering. Although some “12T” microphones are still in existence, all new microphone designs are 48PH.
“prosumer” camcorders. HEADPHONE OUTPUT The Headphone output is located on the rear panel of the mixer. The Mjr Mixer’s headphone amplifier circuitry is designed to drive virtually any headphone with an impedance rating of 32 to 600 Ohms.
BATTERY MONITORING The Mjr Mixer is equipped with a two LED battery indicator located on the front panel of the mixer. When the mixer is turned on, the green LED will light when the battery is in good condition. When the battery needs to be replaced, the Green LED will switch off and the Red LED will switch on alerting the operator to replace the battery at his or her earliest convenience.
This process provides a silk-screened label that is virtually wear proof. The lettering will not wear off as on other mixers. ELECTRONIC TOPOLOGY The new Mjr audio mixer was designed from a clean sheet of paper. It utilizes completely new circuitry designs based upon the latest advances in semi conductor technology.
Ground PSC manufactures a selection of standard Beta Snake cables for use with the new Mjr Mixer. Please note that the Mjr Mixer and M4mkII Mixers use the same cables. These cables are available in standard and camera breakaway versions from any authorized PSC dealer.
The Mjr Mixer can also be used to send audio signals to Betacams via wireless transmitters. The use of transmitters is normally accomplished by connecting the Mjr’s 10 pin output connector to the audio input of the specific transmitter. It is important to note that transmitter placement greatly affects transmit range and clarity.
