The evolution of the entertainment industry has necessitated the creation of an outboard mic/line device to compliment existing mixing consoles. Whether you’re recording, mobile mixing, or broadcasting, there are occasional needs to expand your existing arrangement. Frustrations abounded when it came to adding mics for interviews, karaoke, and live performances because it was cost prohibitive. Now it’s quite inexpensive to enhance your existing gear and expand the number of live mics for any gig. The MLM42S is unique. These mic preamps give you the studio-grade quality you need.
The MLM42S can mix four mics or instruments, each with 3-band tone controls. The Effects Return can be a fifth input when using a line-level instrument like a keyboard. The RCA outputs easily connect to a recording device. A small portable rack could contain the wireless receiver or an amplifier.
The MLM42S can double its inputs as your needs grow. Simply connect the Effects Send of the first mixer to the Effects Return of the second mixer, with the ability to daisy-chain more. Set the Effects control on the second mixer to "Wet."
Each Input section features microphone-level XLR and line-level 1/4" TRS Inputs. Use only one Input jack for each channel. Both Inputs are balanced, but the 1/4" jack accepts unbalanced TS plugs.
If you are using condenser mics, flip the PHANTOM POWER switches to the ON position. 15 volts is enough for most condenser mics. For dynamic mics and line-level devices, leave these switches OFF. Phantom Power only affects the XLR Inputs, not the 1/4" TRS Inputs.
The OUTPUT MIC/LINE switch changes the balanced XLR and TRS Outputs to either LINE-level or MIC-level. Be aware of what sort of signal your mixer or amplifier wants to see before you scare yourself.
The mix of the four Inputs appears on the EFFECTS SEND Output, before the Master Level. This Output can provide the input to an external processor.
The EFFECTS RETURN Input receives the output from the effects processor. To prevent loss of signal when a plug is not installed in the RETURN jack, this jack is a switching type. The SEND is internally connected to the RETURN when a plug is not inserted. The DRY/WET pan control allows the user to control how much processed verses unprocessed signal appears in the final output mix.
An alternative use for the EFFECTS loop is for Expand Output and Expand Input. For example, if you wish to use two mixers, the SEND Output of the first mixer can drive the RETURN Input of the second mixer. The relative mix level of mixer one versus mixer two is determined by the DRY/WET pan control of the second mixer.
Other applications for the EFFECTS loop may use only the SEND Output or only the RETURN Input. For example, a drum machine, keyboard or other mono source may be connected to the RETURN Input. The relative mix of the 4 Inputs versus the source present at the RETURN Input is determined by the DRY/WET pan control. The SEND may be used as a direct Output for recording.
Accelerated-Slope™ Tone ControlsRane’s patented tone control technology produces steeper slopes than normal, thus allowing boost/cut of high and low frequencies without disturbing the critical midband frequencies. The MLM42S features full-cut Tone Controls, allowing much greater contouring than possible with regular controls.
