The SPL crescendo audio now has a little brother – Crescendo Duo is a 2-channel Microphone Preamplifier and is suitable for both individual signals and stereo recordings. As with the large 8-channel preamp, the company’s 120V Rail technology is also included.
The 120V Rail technology is the reference technique according to the manufacturer. This works with a DC voltage of 120 volts and is intended to enable an improved dynamic range, higher signal-to-noise ratio, and stable overdrive resistance. The SPL Crescendo Duo makes use of this and thus promises the same tonal characteristics as the larger Preamplifiers.
Let’s take a look at the features: condenser microphones supply the device with 48-volt phantom power. The high-pass filter eliminates low-frequency noise. You will also find a PAD switch (to lower the input level) and a button to reverse the polarity on the microphone preamp.
VU meters visualize the output level. For more accuracy you lower the displayed levels by 10 dB. Mic gain and output gain can be individually adjusted – very nice. Thanks to the subdivision into stages, tuning the two channels is easier with stereo recordings. The Crescendo duo is perfectly suited for the most demanding stereo recordings but is also ideal for mono signals such as vocals. It is the ultimate front end for all professional recording studios.
Another nice feature concerns the outputs. There are two XLR sockets connected in parallel. For example, you can feed two recording systems at the same time or send the signal into different effect chains. You’ll also note the prominent gain dial, -20 dB pad, output attenuator, and meter trim for, particularly hot signals. A power cord is included.
