1 1.1 1 1.1 ADL 700 Owner’s Manual Overview Introduction Overview Introduction Thank you for purchasing the PreSonus ADL 700. PreSonus Audio Electronics has designed the ADL 700 utilizing high-grade components to ensure optimum performance that will last a lifetime. The ADL 700 is a professional channel strip that includes a tube preamplifier with the same design as the award-winning ADL 600.
1 1.2 Overview Summary of ADL 700 Features 1.
2 2.1 2 2.1 ADL 700 Owner’s Manual Hookup Input Controls Hookup Input Controls Input Source Select. The Input Source Select switch allows you to choose among all signal sources that you have connected to the ADL 700 inputs. It patches the selected input through the signal chain, completely bypassing the other two inputs. The Input Source Select switch also provides a choice of four mic-input impedances: 1500Ω, 900Ω, 300Ω, and 150Ω.
2 2.2 Hookup Compressor Controls ADL 700 Owner’s Manual Polarity Invert: Reverses the polarity of the signal. Power User Tip: Use Polarity Invert when recording with more than one open microphone to combat phase cancellation between microphones. -20 dB Pad: The pad provides 20 dB of attenuation for the microphone preamp only. Power User Tip: The 20 dB pad reduces the signal level coming into your ADL 700, helping to prevent clipping and distortion from high-gain sources.
2 2.3 ADL 700 Owner’s Manual Hookup EQ Controls Compressor Bypass: Bypasses the compressor in the signal chain. Make-up Gain: Compression usually results in an overall reduction of level. The Make-up Gain knob allows you to restore the pre-compression level. You can adjust Make-up Gain from -0 dB to +18 dB. Attack: Attack sets the speed at which the compressor acts on the input signal.
2 2.3 ADL 700 Owner’s Manual Hookup EQ Controls Low Band Frequency: Sets the center frequency of the EQ’s low-frequency band. You can adjust the center frequency from 20 to 250 Hz. Low Band Gain: Sets the attenuation or boost of the EQ’s low band. The gain can be set between -16 and +16 dB. Low Band Peak: When the Peak switch is engaged, the low band of the EQ becomes a standard peak filter with a fixed Q of 0.6. When it is disengaged, the low band is a shelving filter.
2 2.4 Hookup VU Meter and Controls ADL 700 Owner’s Manual High Mid Band Gain: Sets the attenuation or boost of the EQ’s high-mid band. The gain can be set between -16 and +16 dB. High Band Frequency: Sets the center frequency of the EQ’s high-frequency band. You can adjust the center frequency from 2 kHz to 20 kHz. High Band Gain: Sets the attenuation or boost of the EQ’s high band. The gain can be set between -16 and +16 dB.
2 2.5 ADL 700 Owner’s Manual Hookup Master Controls Meter – GR: This switch changes the VU metering to display the compressor’s gain reduction rather than the ADL 700’s output level. 2.5 Master Controls Level: Adjusts the overall output volume of the ADL 700 from -80 dB to +6 dB Power: Turns the ADL 700 on and off. 2.6 Physical Connections Instrument Input: The ¼” TS connector on the front panel is for use with a passive instrument (guitar, bass, etc.).
2 2.6 ADL 700 Owner’s Manual Hookup Physical Connections Line Input: This balanced XLR connection can be used for line-level devices such as keyboards, drum machines, and sound modules. You can also use the line inputs on two stereo-linked ADL 700s to give a stereo mix an extremely full, rich character. To use this input, turn the Source Select switch to the Line position. Comp Link: Use this TRS connection to link the compressor stage of two ADL 700s.

3.0 3.1 3.0 3.1 Tutorial A Brief Tutorial on Dynamics Processing ADL 700 Owner’s Manual Tutorial A Brief Tutorial on Dynamics Processing ADL 700 includes a custom FET Compressor. What follows is an excerpt from a brief tutorial on dynamics processing written by PreSonus president and founder Jim Odom. It is included to help you get the most out of your ADL 700. This tutorial will take you through the basics of dynamics processing. 3.1.
3.0 3.1 Tutorial A Brief Tutorial on Dynamics Processing ADL 700 Owner’s Manual The world’s best mixing consoles offer compression on every channel because most instruments need some form of compression, often very subtle, to be properly heard in a mix. 3.1.2 Compression Demystified Punch, apparent loudness, presence—these are just three of the many terms used to describe the effects of compression. Compression is a form of dynamic-range (gain) control.
3.0 3.2 ADL 700 Owner’s Manual Tutorial Equalizers ass guitar can be difficult to record. A consistent level with good B attack can be achieved with proper compression. Your bass doesn’t have to be washed out in the low end of the mix. Let the compressor give your bass the punch it needs to drive the bottom of the mix. 3.2 Equalizers Your ADL 700 is equipped with a 4-band semi-parametric EQ.
3.0 3.2 ADL 700 Owner’s Manual Tutorial Equalizers bandwidth is also useful in boosting pleasant tones of an instrument such as the attack. Take for instance, a kick drum. A kick drum resonates somewhere between 60 to 125 Hz, but the attack of the kick drum is much higher at 2 to 5 kHz. By setting a narrow bandwidth and boosting the attack a bit, you can achieve a punchier kick drum without overpowering the rest of the mix. A broad bandwidth accentuates or attenuates a larger band of frequencies.
3.0 3.2 ADL 700 Owner’s Manual Tutorial Equalizers •• Your memory is not what you think it is. Comparing a flat EQ and the curve that you’ve created allows you to see and hear exactly what you’ve done. So be honest with yourself. Sometimes that EQ setting you’ve been working on for 15 minutes is not the right choice, so move on. •• Never be afraid of taking a risk. The best EQ tricks were found by mad scientists of sound.
