PreSonus announces the ADL 700 channel strip.
It combines a Class A tube preamplifier with a variable, FET-based compressor and a four-band semi-parametric equalizer.
The new channel strip provides separate balanced XLR mic, balanced XLR line, and ¼" TS instrument inputs and a single balanced XLR output.
The ADL 700 incorporates a single-channel version of the PreSonus ADL 600 two-channel tube preamplifier. It incorporates one 12AT7 and two 6922 vacuum tubes per channel, operating with ±300V power rails.
Among the features of ADL-series preamps is an Input Source Select switch with variable mic-input impedance. This switch enables you to choose among signal sources and patches the selected input through the signal chain, bypassing the other two inputs. It also provides a choice of four mic-input impedances: 1500Ω, 900Ω, 300Ω, and 150Ω. Lowering or raising the ADL 700 mic-input impedance can create subtle coloring and filtering effects, enabling you to get a variety of tonalities without using the EQ.
The ADL 700 compressor features include variable attack, release, threshold, ratio, makeup gain, and bypass. When Threshold is turned fully counterclockwise to the ST position, the onboard compressor controls are bypassed, and compression is controlled externally via a Stereo Link connection to a second ADL 700.
The preamp offers 48V phantom power, polarity reverse, and a -20 dB pad. In addition, it provides variable mic-input gain, employing an 8-position rotary switch that provides 35 dB of gain in 5 dB increments. A Trim potentiometer (±30 dB) allows you to make adjustments to the final preamp stage of the ADL 700 input.
You also get a -12 dB/octave high-pass filter whose frequency threshold can be set at 20 Hz, 40 Hz, 80 Hz, or 200 Hz, or it can be turned off completely.
The 4-band semi-parametric EQ combines isolated filters and per-band Q. All bands have Gain (±16 dB) and Frequency controls, with overlapping frequency ranges and fixed Q (0.6). The low and high bands are switchable between shelving and peak.
Dual-mode analog VU metering enables monitoring of output and gain-reduction levels. A -6 dB switch offsets the meter for use with hot source signals. A master level control adjusts the overall output from -80 to +6 dB.
Pricing & Availability:
The ADL 700 is expected to ship in the fourth quarter of 2012 with an expected MAP/street price of $1,999.
