Adcom GFP-915SE Stereo Preamplifier at Vinyl Sound Buffalo NY The Adcom GFP-915SE is the next evolution of Adcom's renowned preamplifier line. Building on the legacy of the original GFP-915, the SE version introduces triple amplifier output support, Bluetooth 5.4 wireless streaming, and high-resolution digital inputs without compromising the low-noise signal purity that defines the GFP-915 lineage. Available at Vinyl Sound in Buffalo, NY. Triple Amplifier Output Support The GFP-915SE is designed for complex, high-performance audio setups requiring simultaneous connection to multiple amplifiers. Three independent output paths — unbalanced Main 1, unbalanced Main 2, and balanced XLR — allow for multi-zone configurations, dedicated subwoofer integration, or bi-amping arrangements without additional splitters or converters. The upgraded software platform provides smooth input switching and stable operation across all analog and digital signal paths. Bluetooth 5.4 and High-Resolution Digital Inputs Qualcomm Bluetooth 5.4 enables high-resolution wireless streaming with low latency and robust connection stability, bringing modern convenience to a high-fidelity signal chain. USB and Optical inputs support playback up to 192kHz / 24-bit, ensuring the GFP-915SE is fully compatible with the highest-quality digital sources available. All digital paths are managed through low-noise circuitry to preserve signal integrity from source to output. Phono Stage and Analog Source Integration The GFP-915SE integrates a full MM/MC phono stage with RIAA accuracy of ±0.25dB from 20Hz to 20kHz, making it a complete solution for vinyl playback within a high-performance system. Seven analog inputs provide comprehensive source management for CD players, streamers, tuners, and other line-level components. Every analog connection is routed through precision signal paths and shielded circuitry to minimize noise and preserve the natural character of each source.

(7.1 kg) Shipping Weight 20 lbs. (9.05 kg) Frequently Asked Questions What is the Adcom GFP-915SE? The Adcom GFP-915SE is a high-performance stereo preamplifier featuring triple simultaneous amplifier output support (Main 1 unbalanced, Main 2 unbalanced, and balanced XLR), an MM/MC phono stage, Qualcomm Bluetooth 5.4, USB and Optical digital inputs up to 192kHz/24-bit, and seven analog inputs. It is available at Vinyl Sound in Buffalo, NY. What does triple amplifier output support mean on the GFP-915SE? The GFP-915SE provides three independent output paths that can operate simultaneously: an unbalanced Main 1 output, an unbalanced Main 2 output, and a balanced XLR output. This allows the preamplifier to drive three separate power amplifiers at once — useful for bi-amping, adding a dedicated subwoofer amplifier, or distributing audio to multiple zones without additional signal splitting hardware. What phono cartridge types does the GFP-915SE support? The GFP-915SE includes a built-in phono stage that supports both Moving Magnet (MM) and Moving Coil (MC) cartridges. Input sensitivity is 3.5mV for MM and 25mV for MC, with RIAA equalization accuracy of ±0.25dB from 20Hz to 20kHz. Signal-to-noise ratio on the phono stage is 95dB or greater for both MM and MC. What digital sources can connect to the GFP-915SE? The GFP-915SE accepts digital audio via USB and Optical inputs, both supporting playback up to 192kHz / 24-bit resolution. In addition, Qualcomm Bluetooth 5.4 enables high-resolution wireless streaming from smartphones, tablets, computers, and other Bluetooth-enabled devices with low latency and stable connection quality. Can the GFP-915SE be used for bi-amping? Yes. The GFP-915SE's three simultaneous output paths make it well suited for bi-amping configurations where separate power amplifiers drive the high-frequency and low-frequency sections of a compatible loudspeaker. Main 1 and Main 2 unbalanced outputs and the balanced XLR output can each be routed to a dedicated power amplifier without any additional signal splitting hardware.
