PRE 32 Stereo Preamplifier

The PRE32 is an upgradable audiophile pre-amplifier designed to match the Primare A34.2 and all Primare power amplifiers. It features the comprehensive OLED display and control parameters established by the EISA award-winning I32 integrated amplifier. The PRE32 is housed in a heavy gauge alloy steel chassis, and incorporates two pairs (L/R) of low-noise balanced XLR inputs and 4 pairs of RCA inputs. In addition there are two pairs of RCA outputs and a single pair of balanced XLR outputs, as well as a record output, RS232, trigger, IR and RF inputs. The option of an upgrade board offering MEDIA/streaming connections such as USB, iPod, LAN etc., is provided.

Audiophile Topology

All signal paths are fully balanced and as short as possible. All signal treatments (source selection, volume and channel balance trims) are performed purely in the analogue domain. Unbalanced inputs are converted to balanced signals by a conversion stage buffered by the excellent sounding Burr Brown OPA2134 op-amps and fed to volume and balance controls employing closely matched NJW1195 attenuators in a balanced configuration. Source selection is via high performance signal relays. Balanced signal transmission means that two identical signal lines are used to carry the same signal with opposite phase. Any noise is common to both lines, is present in equal amounts and with identical phase. At the receiving end a (differential) receiver retains the opposite phase signals (music) and rejects the common phase ones (noise) leaving

only the pure original signal. Balanced circuits therefore keep the signal as free as possible from interference.

The four (L/R balanced) single-ended 16dB gain stage modules are fully separated. Each has its own proprietary PCB, incorporating a custom designed copper heat sink, which also acts as a shield. The gain module layout incorporates ultra-short signal paths and only the finest discrete components such as MOSFET transistors, MELF resistors and polypropylene capacitors. Active, well-balanced current sources are used instead of passive resistor networks. The PRE32 is DC coupled from input to output. There are no capacitors in the signal path. Instead active DC servos are used to compensate for any DC present, ensuring that the outputs are always free from DC components. All the front panel control components are kept well separated from the analogue part of the PRE32 by the front panel’s intuitive design: the electronics are placed between the

front panel and the main steel chassis.

Ultra low-power standby

The PRE32 incorporates a very low eco mode for standby. Power consumption is just 0.2W. In order to minimise high frequency components originating from the standby power supply (high performance switch-mode) when the PRE32 is in operation, the standby supply is switched off when the PRE32 is powered up, and a discrete linear power supply consisting of only the finest discrete power supply components and an Rcore mains transformer, takes over. Analogue and digital power supplies are kept well separated. For the analogue side a discrete ultra-fast voltage regulation circuit using discrete power transistors is used. The power supply capacitor bank is large (25.000uF) and for lower ESR and best performance, is divided between many smaller capacitors. These measures have produced extremely good THD+N and S/N ratio figures for the PRE32.

Upgradeable Design

A media upgrade will be available, which offers up to 24 bit/192 kHz streaming of files from Internet, NAS or PCs, as well as Internet radio content and also digital audio input from a range of devices including CD players, smart phones, personal players, sat boxes etc.

UPGRADE

A high quality aptX Bluetooth upgrade for the PRE60 preamplifier, NP30 network player and the MM30 equipped network streaming versions of the I32 integrated amplifier and PRE32 pre-amplifier. It takes the form of a small internal circuit board and external antenna (for improved reception), which installs easily, the threaded antenna input replacing the FM/DAB terminal on the MM30 fascia and using a vacant (pre-prepared) portal on the back panel of the PRE60 and NP30.

For compatibility with Primare’s high-performance audio design, the receiver-only module supports high quality Bluetooth via aptX, AAC, MP3 but rather than use an integrated DAC (as employed by other BT upgrades) the output is fed to the product’s own Sample Rate Converter and up-sampled to 192kHz for optimum performance through the existing high resolution DACs. In this way Primare’s Bluetooth Upgrade is among the most audiophile available, adding excellent Bluetooth sound quality to the convenience of wireless Bluetooth connections.

Following an easy software update via the PrimareApp, the BT input is added to the product control menu in a discrete BT section, which allows for the renaming of the input for the product display and the also the BT connection. The OLED display will show the device name and also indicate if the device supports AAC or aptX.

Bluetooth Product features

- Supports aptX, AAC, MP3 for high quality Bluetooth audio.

- The upgrade comes with an external antenna for better reception.

- The Primare BT Upgrade is a receiver only. The incoming signal is fed to the product’s SRC, is

up-sampled to 192kHz and then runs through the product’s high performance DACs.

- Installation is easy; software update is through the PrimareApp or from the MENU.

- BT input is added to the product MENU, BT-input name and Bluetooth name are editable

- OLED display will show device name.

- If the device supports AAC or aptX it will pop up on the OLED display.

Easy User Interface

An easy set-up menu is available via the PRE32’s graphical display, which is dimmable in four steps. The display auto-dims after a few seconds and returns to programmed brightness at the touch of a control. Set-up includes power-up volume, input re-naming (up to 6 characters), input disabling and trim function (volume and balance

MM30 DAC/Media Module

The Media Upgrade adapts the EISA award-winning I32 integrated amplifier and the recently introduced PRE32 stereo amplifier for audiophile streaming, internet radio and gapless audio playback, through integration with UPnP devices such as PC/Mac/NAS iPod®, iPad®, iPhone® or USB thumb drive. It’s a genuine 24/192 DAC board including coax, TOSLINK, USB-A and USB-B inputs (incorporating an asynchronous master clock for low jitter), and a high resolution coax output. The I32 and PRE32 can be purchased with or without media upgrade. Primare Control Apps will be available for iPhone/iPad and Android.

Features

External Inputs:

- 1 Coax input at 192kHz

- 3 Toslink inputs at 192kHz

- (1 antenna input for DAB or FM signals – future upgrade)

- 1 asynchronous USB-B input allowing playback of 192kHz audio from a computer

- 1 asynchronous USB-A input, allowing the device to play audio from USB/Iphone

- 1 Coax output transmitting at 192 kHz. Always connected to the active input source.

Inputs selectable from I32 and PRE32

Each input will have its default name, but can be renamed by the user (up to six characters) in the same way as any other input in the I32/PRE32 display architecture. The inputs are selected using the C23 remote control or the front panel input selector switch.

- Coax input

- Toslink 1-3

- USB-B input (from computer USB interface)

- USB-A input, allowing the device to play audio from USB/Iphone

- MEDIA input – this input must be selected to play streaming media.

- DAB+/FM – (this is a future board upgrade)

The media module can be controlled by an external App:

- Switch to the MEDIA input

- Use either the Primare App (for Iphone®/Ipad®, or the Android version) or any generic UPnP App.

- Some features, like playing media from USB thumb drive, USB-connected Iphone, Ipod®, Ipad®, and playing vTuner, require the use of the Primare App.

Network connection

The Media board can be connected to a wired or wireless network. Network settings can be found under general settings, and allow the user to:

- scan for wireless networks

- explicitly name a network SSID

- Configure DHCP or Fixed IP
