C2440 QUICK START UP If you're like most new owners, you're probably in a hurry to plug your mixer in and use it. Here are some brief instructions to get you going quickly. With the mixer unplugged and the unit turned off, complete the following p r o c e d u r e s : 1. CONNECTING AC POWER TO YOUR MIXER • The mixer can be used with 120 or 230VAC (it automati- cally switches internally) • Use only a grounded (3 prong) outlet to prevent a shock hazard. This gives the quietest grounding for your mixer. 2. CONNECTING INPUTS TO YOUR MIXER • For low level balanced devices such as microphones, plug into the balanced MIC inputs using a shielded microphone cable with XLR ends. • For high level balanced or unbalanced devices such as instruments & Keyboards, plug into the LINE input jacks using a shielded cable with 1/4" Stereo or standard phone plugs. Adjust the GAIN knob for the mic or line input being used. 3. TURNING YOUR MIXER ON • Adjust all channel FADERS and master LEVEL controls to their OFF positions • Adjust all channel HI, MID, and BASS controls center . • Adjust all the Channel "PAN" controls to their center position. • Turn the mixer on by the rear panel POWER SWITCH and watch for the POWER LED to come on. Your mixer is now ready to operate. become AUX 5 (the control labled 3-5) and AUX 6 (the control labled 4-6). This feature gives you a total of 4 auxiliary mixes and reduces the number of controls that need to be a d j u s t e d . 10. STEREO PANNING Each channel's PAN control allows sweeping stereo effects when panning from L to R for recordings or live sound. Superior channel separation is available because of the "dual element" pan controls providing 15dB greater Left & Right separation over standard mixers. A true stereo image can be obtained from any of the output connections marked L & R. 11. CHANNEL SIGNAL GREEN LED The signal indicator is pre-fader and post EQ. This LED verifies that the channel is receiving a signal from the mic or instrument inputs. C2440 CONTROLS CHANNEL FEATURES 1. 1/4" LINE IN 1 The line connectors are for connecting balanced and unbalanced instruments, mics and line level sources such as drum machines or keyboards. 2 2. XLR MIC IN 3 The balanced Mic inputs are for connecting pro micro- phones that use XLR connections. 3. CHANNEL INSERT/CHANNEL DIRECT 4 To insert a channel effect use a 1/4" TRS (Tip Ring Sleeve) 5 instrument cable and fully insert it into the jack. Connect 6 the other end of the cable to the effect's output. To use as a direct output for multi-track recording use a 1/4" instru- 7 ment cable and insert to the first "click" (1/2 insert). Connect the other end of the cable to an input on a multi- track recorder. 4. GAIN CONTROL 8 Adjusts the GAIN when connecting various instruments & mics. The type of mic (uni-directional, omnidirectional, etc) and model will require a custom GAIN settings for each individual mic. Monitor the GAIN level with the PEAK 9 LED. If an LED is constantly illuminated, decrease the amount of GAIN. If distortion is present, decrease the amount of GAIN until the distortion is eliminated. 10 5. LOW CUT SWITCH 75 Hz low cut filter helps eliminate unwanted low frequencies. Great for reducing "boom" noise from mic stands or from hollow body acoustic/electric guitars. This filter can also help "punch up" the bass by turning up the LOW tone control while using the LOW CUT switch. 11 12 13 14 15 6. MID SHIFT SWITCH The MID SHIFT is an exclusive feature giving you a choice of two different midrange center frequencies. This is ideal for vocals and/or instruments. The MID SHIFT is easier to use than conventional sweep controls because it allows you to compare for the best vocal or instrument sound by switchng between the two MID frequencies.(2.5k Hz or 700 Hz) 7. ACTIVE 3 BAND CHANNEL EQ This 4 buss mixer provides studio quality tone controls with distortion less than .01%-exceptionally clean for recording & live sound! The ±15 dB boost and cut gives an overall 30 dB range of powerful EQ control. The active circuits deliver deep bass from the 20-80 Hz LOW control. The MID control works in the 2.5k Hz range or the 700 Hz range depending on the MID SHIFT switch. The HI control functions at 11-20k for crisper highs. Start out with all tone controls at their center zero position. Determine which position your MID SHIFT sounds best at,then cut or boost your HI, MID and LOW frequencies as needed. If you are trying to mic instruments such as acoustic guitar or drums, try various mics and mic placement before adjusting your tone controls (condenser mics work well for these applications). Cutting and boosting frequencies improper 16 ly can cause an "un-natural" sound to your vocals or instruments. Your goal is to achieve a natural sound for the entire performance or recording. 8.CHANNEL AUX 1-2, PRE-POST AUX 1 & 2 can be used as 2 individual monitor mixes. Adjust the monitor level from each channel with the AUX 1 & 2 controls. The PRE-POST switch should be set to PRE (pre-channel EQ and pre-fader) when using AUX 1 & 2 as monitor mixes. The PRE-POST switch should be set to POST (post-channel EQ and post-fader) if AUX 1 & 2 is to be used for effects sends. 9. CHANNEL AUX 3-4, 5-6 Here are 4 more AUX controls paired up. With the 5-6 switch OUT the two AUX controls become AUX 3 (the control labled 3-5) and AUX 4 (the control labled 4-6). When the 5-6 switch is in the IN position, the AUX controls then 12. CHANNEL PEAK RED LED This peak indicator is pre-fader and post EQ. A constantly lit LED indicates the signal probably needs a reduction in GAIN to prevent input overloading. 13. CHANNEL MUTE SWITCH Mute a channel instantly without touching your faders. This is extremely useful when you need to mute channels but can't afford to lose fader settings. 14. CHANNEL PFL SWITCH This switch allows the operator to monitor each channel to set tone, gain and effect levels before turning up the fader 15. CHANNEL ASSIGNMENT SWITCHES These switches assign the channels' signal to the group faders for sub-mixing and to the Left & Right faders in the
