The sound quality of the two-channel device is shown to its best effect when particularly recording vocals or acoustic instruments. High precision and naturalness help every vocal timbre to develop fully and emphasise the sound character of acoustic instruments. Since even the differences of the used microphones are shown clearly up to the finest nuances, the Goldmike gives a lot of room to experiment.

The lively sound quality and extreme low noise predestine the Goldmike for digital recording. The dual-mono construction of the class A tube amp guarantees a perfect channel separation and thus enables high spatial imaging for stereo recordings from piano to choir.

With the Goldmike reinforcements up to 72 dB are possible. A full tube preamp can’t reach those values. The tube/ IC design of SPL, however, combines the tonal qualities of tubes (improved spatial imaging, high in detail, pleasant soft focus) with high, very linear amplification performance and excellent common mode rejection. Thus the Goldmike is the perfect pre amp, even for high-end HD recording, as the dynamic range of 111 dBu proves: This value is above the, in practice, achieved values of 24-bit recording.

Equipment: The FLAIR circuit enhances the presence and clarity of the signal and allows sound optimisation while recording in particular for voices.

In addition, the Goldmike has a high pass filter at 50 Hz, phase reverse switch, 30 dB pad, 48 V phantom power with separately filtered power supply, high quality Alps potentiometers, crackle-free switches, five LEDs for each channel, two illuminated VU meters, star point grounding for best sound quality, thick conductors for stable voltage supply, a complex filtered power supply (6000 µF in the main power supply, 400 µF in tube power supply), symmetrical XLR inputs and outputs as well as unbalanced jack outputs. The ground-lift circuit helps to avoid ground loops.

The Chandler TG2 mic preamp has evolved into the classic studio standard for microphone recordings of electric guitars in recent years. Both dynamic (e.g. Shure SM57, Sennheiser e906) as well as condenser microphones (Neumann U87, U47) or ribbon mics (Royer 121) can record a punchy, differentiated and noble guitar sound meeting the highest demands, which is present and dominant in the mix from the beginning.

The TG2 is also suitable as a preamp for bass drum and snare giving those instruments the punch and aggressive timbre known from countless records.

As vocal preamp it is suitable especially with the Shure SM58 for rock-like and loud vocalists who want to be heard. That is why the TG2 mic preamp can be found in all the major studios and is used by celebrities like Michael Brauer (Coldplay) and Michael Wagner (King's X Metallica) on a daily basis. Anyone looking for an "all-rounder" mic preamp for rock music will find it with the TG2.
