The recording industry has gone through some dramatic changes in the past years. The home recording market produces professional results with modest investments. Mainly inexpensive mixing consoles with lots of channels and 8-bus-option are being used. High class filtering and microphone preamplification are not incorporated in these systems. The “direct to DAT” recording philosophy has created another growing market. Sampling and direct cutting through quality mic preamps has become popular. The MIKEMAN is the ideal choice for both recording situations. It is the cost-effective entry into high performance preamplification and ideally suited to partner your favorite mic in getting the best possible performance on tape. It improves the sonic quality of small mixing consoles with two channels of superior preampli- fiaction and it is the ideal tool for “direct to DAT”applications.

The MIKEMAN is a dual channel microphone preamplifer with excellent noise and CCMR specs. It has a large input headroom (+26,5 dB), which makes limiting a less important issue. Microphone and line level signals can be preamplified up to +72 dB. Activating the padding switch attenuates the preamplifier stage by -35 dB. The superior phantom power supply for condensor microphones is also ideal for old tube microphones which need a very stable and clean +48 V phantom powering. The Phase Reverse switch is used to change the polarity of the micro- phone. PPM-meters displaying output values between -18 dB and +9 dB are also incorporated. The input and output stages can optionally be equipped with beyerdynamic transformers.

The housing of the MIKEMAN has the standard 19" EIA format and occupies 1 unit (1 U = 44 mm) in your rack. When installing the unit in a 19" rack, the rear side of the unit needs some support, especially in a touring case. The MIKEMAN should not be installed near units which produce strong magnetic fields or extreme heat. Do not install the MIKEMAN directly above or below power ampli- fiers or digital processors. If possible, the MIKEMAN should be placed in an »analog rack« where the majority of (or all) the equipment installed is analog. This eliminates problems which could result from interfering high-frequency signals such as clock frequencies, MIDI or SMPTE control signals.

Check that the voltage details quoted on the back panel are the same as your local mains electricity supply. Use a minus (-) screwdriver to set the voltage selector to the voltage for the area in which the unit will be used.

Never cover up the ventilation slots on the top of the unit. If, during operation, the sound is interrupted or indicators no longer illuminate, or if abnormal odor or smoke is detected, or if water is spilled on the unit, immediately disconnect the power cord plug and contact your dealer or an authorized service center.

Only clean your MIKEMAN with a soft, lint-free cloth. Use only standard cleaning agents. Never use alcohol or paint thinner, because they may damage the finish.
