3 Inputs Handmade Portable Mixer
This small size and low weight portable mixer lends itself to being mounted on a camera or attached to a belt. It has 3 inputs and 2 outputs with limiters on microphone inputs and the main outputs. There are two configurations; a one mic plus two line inputs or three mic inputs. It is capable of being set and left to process the audio.
FEATURES
- Mic Inputs: 1 or 3 electronically balanced type with XLR connector, 48V phantom power, high-pass filter, gain control and mic or line input selection
- Line Input: Instrumentation grade electronically balanced with gain/level control
- Routing: Each input is routed to left, right or left and right by two toggle switches
- Output: Electronically balanced with XLR type connectors and stereo rotary level control. Can be unbalanced without loss of level or degradation of quality. A push-button switch selects line or microphone output levels to the XLR connectors. A 3.5mm jack socket carries output signals at microphone level
- Limiters: Incorporated in the microphone inputs and the two main outputs. The mic input limiter is permanently in circuit. A push-button switch introduces the output limiters into circuit and two LEDs indicate the onset of limiting
- Line-Up Oscillator: 1kHz tone injected output level
- Powering: Either external power via a 4pin Hirose connector, or a separate PP3 mixer. A LED indicates power present and flashes when the voltage is too low
