JBL SA750 (75th Anniversary Edition)

Audio Section

Integrated Stereo Amplifier & Streamer: In honor of their 75th anniversary, JBL has crafted the SA750 integrated amplifier with retro styling, commemorative badging, vintage teak-wood veneer side panels, and thoroughly modern features, connectivity, and amplification. The SA750 is inspired by the classic JBL SA600 amplifier from the 1960's, updated with high resolution streaming audio, wireless connectivity, Dirac Live room correction, and Class G amplifier technology.

Class G Amplification: The JBL SA750 ntegrated amplifier utilizes Class G amplifier technology that is both clever and efficient. Class G amplification implements multiple power supplies rather than just a single supply. If a dynamic signal is received that goes beyond the capability of the first power supply, the secondary supply is gradually brought in up to full rated power output as required. This gives a very efficient design as additional power is only used when required. The first power supply is of lower power and within this region runs in pure Class A, which has no crossover distortion. As the secondary supply is only used when required, extreme levels of power are possible because very little energy is wasted in the amplifier as heat when it is not being used. Without control this power would be ill-used, so multiple output devices within the amplifier keep a tight grip on the loudspeaker at all times, ensuring your listening experience never lacks dynamics and detail.

• 8-Ohm Power Rating: 130 watts x 2 channels @ 20-20kHz into 8-ohms
• 4-Ohm Power Rating: 200 watts x 2 channels @ 20-20kHz into 4-ohms

High Resolution DAC: The JBL SA750 integrated amplifier utilizes a 32-bit ESS Sabre DAC (ESS9038K2M) with support for 2ch digital music audio files up to 24-bit/192kHz, providing audiophile-grade high-resolution sound quality. The SA750 allows you to choose between a number of DAC filters to suit your listening preference and application. You can choose between the following -

• Brick Wall: No phase shift, but introduces both pre and post ringing artefacts.
• Apodizing (Default): A compromise between phase, frequency response and ringing. Its main advantage is that it removes most of the ringing that has been introduced upstream in the recording process when the original material was recorded and mastered.
• Corrected Minium Phas Fast Roll Off: Low pre-ringing and the phase response varies at higher frequencies. There is more post ringing compared with linear phase and apodizing filters.
• Minimum Phase Slow Roll Off: No pre-ringing artefacts but can introduce phase shifts at higher frequencies. It has less post ringing than the Minimum Phase Fast Roll Off, but this is still higher than the linear phase filter options. Very high frequencies in the last half octave of the filter pass band will be slightly attenuated.
• Minium Phas Fast Roll Off: No pre-ringing and the phase response varies at higher frequencies. There are significantly higher amounts of post ringing compared with the linear phase filter options.
• Linear Phase Slow Roll Off: Low and equal levels of pre and post ringing. No phase shifts but can introduce high frequency aliasing at a higher level than linear phase fast roll off. Very high frequencies will be slightly attenuated.
• Linear Phase Fast Roll Off: Higher and equal levels of pre and post ringing compared with linear phase slow roll off. No phase shifts and with minimal high frequency aliasing compared with slow roll off.

MQA Support: The JBL SA750 features a full MQA decoder, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording in the highest possible sound quality. At this level of playback you are hearing what was created in the studio - with precise file and platform-specific DAC compensation and management. MQA is supported via UPnP and USB.

Dirac Live Room Correction: There is a proprietary automatic loudspeaker setup function, known as Dirac Live, built into the JBL SA750. Using a computer application (for Windows & Mac), Dirac Live attempts to set all the essential speaker settings for all the speakers in your system. It also calculates room equalization (Room EQ) filter values to remove some of the worst effects of resonant frequencies in the listening room. The integrated amplifier comes with a calibration microphone which should be inserted into the microphone input of the supplied USB sound card and then into a USB socket on a Windows PC or Mac computer that connected to the same network as the JBL integrated amp and positioned at the main listening position. This microphone picks up the special calibration tones generated by the speakers when Dirac Live is run. The integrated amp then analyzes the signal and computes - Speaker Type, Speaker Distance, Speaker Level, and Room EQ. You can store up to three Dirac EQ curves in the SA750.

Analog Direct Mode: The JBL SA750's Analog Direct Mode lets you bypass certain elements of the integrated amp's audio processing to allow for a purer listening experience. The Analog Direct Mode bypasses the ADC (Analog-to-Digital Converter), DSP, (Digital Signal Processor), and DAC (Digital-to-Analog Converter) to allow the analog signal to be sent directly to the preamp stage for the purest signal path possible.

Processor Mode: Processor mode can be assigned to the rear-panel line-level analog inputs. In this mode, the volume of the integratd amp is set to a fixed level. This mode allows the use of the SA750 in conjunction with an AV receiver in a combined home cinema and two channel listening environment. You can specify the required volume level for the Processor Mode input; the default is volume is 30.

Analog Inputs: The JBL SA750 integrated amplifier is outfitted with six total analog inputs; including three rear-panel line-level stereo RCA inputs, a front-panel line-level 3.5mm Aux input, and two rear-panel Phono inputs (MM/MC).

• Line-Level Inputs: The JBL SA750 is equipped with a total of four line-level analog inputs. There are three line-level stereo RCA inputs on the rear-panel and a 3.5mm Aux input on the front-panel.
• Phono MM/MC Inputs: The SA750 provides Phono inputs and a pre-amp stage to work with the low-voltage output from either a MM (moving magnet) or MC (moving coil) cartridge. Each cartridge type has a dedicated input on the rear-panel

Optical & Coaxial Digital Inputs: The JBL SA750 integrated amplifier is outfitted with two optical (toslink) digital inputs and two coaxial (RCA) digital inputs that support 2ch stereo PCM audio.The optical digital inputs support 32kHz, 44.1kHz, 48kHz, 88.2kHz, and 96kHz sampling frequencies; while the coaxial digital inputs support 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, and 192kHz sampling frequencies.

USB-A Port: The rear-panel USB-A port (5V/1A) supports playback of a variety of music files store on a USB MSC (mass storage class) device, such as a thumbdrive or HDD (hard disk drive). An external HDD will require a separate AC power supply. Supported music files include MP3, WMA, AAC, WAV, and FLAC (up to 24-bit/192kHz); as well as MQA audio files. The USB device should be formatted in FAT 12 or FAT 32.

Outputs: The JBL SA750 integrated amplifier is outfitted with a set of binding post speakers outputs to connect a pair of loudspeakers, a set of stereo RCA preamp outputs to connect to an external power amplifier, and a headphone jack output for connection of a set of headphones.

• Binding Post Speaker Outputs : The JBL SA750 is equipped with a set of binding post speaker output terminals that will accept bare wire (up to 10AWG), pin-connectors, spade-lugs, and banana connectors (single only). You will need to remove the plastic inserts from the binding-post terminals to use banana plugs. The binding post terminals are gold-plated for excellent audio signal transfer. You can connect a pair of 8-ohm or 4-ohm loudspeakers to the SA750 integrated amp.
• Stereo RCA Preamp Outputs: The integrated amplifier has a set of stereo RCA pre-out that let you use the SA750 as a dedicated pre-amplifier or as part of a bi-amplified system.
• Headphone Jack Output: The front-panel 3.5mm (1/8") headphone jack accepts headphones with an impedance rating between 16-ohm and 2k-ohm. When a set of headphones is connected to the headphone jack, the integrated amp's speaker outputs and preamp outputs are muted by default. You can configure the integrated amp's speaker and preamp outputs to remain active when headphones are connected.

Max Volume: You can limit the maximum volume when the SA750 is switched on or comes out of Standby. The SA750 comes on at this stored volume setting if the last used (possibly very loud) volume exceeds this value. You can also limit the maximum volume setting the SA750 can be turned up to for the hardwired or wireless input sources. This is a useful feature to prevent accidental overdriving of low power-handling speakers. These max volume settings are stored in memory and recalled each time the unit is powered up.
