FRONT PANELA B C D EF G H I J K L MA PHASE - Changes the polarity of the Mic signal from 0º to 180º In 0º a positive going signal at the inputproduces a positive going signal at the output. Be aware that many mics were built before the XLRstandards were agreed upon (PIN 2 = HOT). The effect of this switch is apparent when two mics areused on one instrument. In general the setting with the most lows is probably "in phase". One exampleis with one mic above a snare drum and another mic below. When combined the result will usully be aloss of bass because one mic is hearing the skin going toward the mic while the other hears the skingoing away. "Flipping" the polarity of one of the mics usually solves the problem. Anytime leakage isobvious then phase should be a concern. Distance is one factor that makes selecting the phase more ofa decision than a science. Certain instruments sound more natural when the phase of even a single micis right. Vocalists will hear the headphones better if the phase is correct too.B PHANTOM - When ON puts 48 volts onto the MIC INPUT XLR. Leave it OFF for dynamic or ribbonmics, tube condensor mics or passive DI's and ON for most solid state (FET) condensor mics. Youmust gently PULL the switch to toggle. This is a safety feature to prevent damage to speakers,recordings, the mic or the input transformer. A shorted mic cable or unbalanced input combined withPHANTOM could also cause damage. The LED indicates PHANTOM POWER.C EQ INPUT - Selects either the MIC PRE OUTPUT or LINE INPUT to feed the EQ SECTION. If aCompressor (etc) is patched between MIC PRE OUTPUT and LINE INPUT then this switch acts as a"INSERT" switch.D MIC GAIN Controls the amount of microphone pre-amp gain from Off to +45 dB. More gain if needed isavailable with the LINE GAIN control.E LINE GAIN - Controls the Output Level (before the meter).F EQ / BYPASS - When this switch is up the EQ section and amplifier are in circuit. BYPASS mode is a"hardwire" bypass connecting LINE INPUT directly to LINE OUTPUT.G 100 HZ / 40 HZ - Switches the LOW FREQUENCY EQ "center" frequency.H LF SHELF / PEAK - Switches the LOW FREQUENCY EQ to a "modified" shelf and lowers the Q whenup. Shelf mode affects frequencies below the center frequency which means if "40 HZ" is selectedlittle difference will be heard. See the typical EQ curves on page 7 and the explanation on page 6.I LOW FREQUENCY EQ - Cut and Boost at 40 or 100 HZ in 2 dB steps. A quality Grayhill gold contactswitch is used rather than a pot. At "0" position this section is truly bypassed. In SHELF mode thesteps are smaller and the maximum cut is 7 dB and boost is 6 dB.J HIGH FREQUENCY EQ - Similar to above except highs are boost and cut.K HF SHELF / PEAK - Similar to above except highs are affected. See the curves.L HIGH FREQUENCY SELECT - Choice of 3kHz, 5 kHz, 7 kHz, 10 kHz and 15 kHz.M VU METER - Reads the signal from the LINE OUT XLR. 0 VU = +4dBm.N POWER SWITCH - This switch should be up and both the LED and meter will illuminate - Sound willfollow in about 10 seconds. Let it warm up 15 minutes for best results. Do not flip the power on andoff rapidly as this could damage the bridge rectifiers in the power supply.PHANTOMPHASEBYPASSEQ 100 HZ40 HZLINE GAINPOWERPULLEQ INPUTPEAKLINE INMIC PRE OPMANLEYMIC / EQ 500 COMBOFULLY DIFFERENTIAL ALL TUBE180º48V ONSHELF-0+246810246810MIC INPUTLEVEL LEVEL108642 246810SHELF35 71015-0+dB KHz0ºPEAKdBLFHFDESIGNED BY DAVID MANLEYHANDCRAFTED IN CHINO, CALIFORNIA
