Description

With Klimax Solo 500, our latest top-tier innovations powerfully coalesce into the best compact monoblock amplifier we have ever made.

Klimax Solo 500 features novel and original Linn technologies which combine to produce staggeringly low distortion measurements, with superb signal-to-noise ratio and incredible efficiency (voltage rail control).

In a normal setup, one hears the accumulation of interactions between speaker and amp – a combination of non-ideal characteristics which result in artefacts heard in the music. Linn’s focus on relentless minimisation of distortion within the amp, and unilaterally consistent output, means that Klimax Solo 500 introduces negligible harmonics or background noise to the music signal.

Linn’s unique combination of digital and analogue expertise has allowed them to optimise and linearise every internal stage of the amplifier to consistently produce exceedingly high performance.

Installation

We recommend that your Klimax Solo 500 power amplifiers are unpacked, installed and adjusted by an authorised Linn retailer.

To get the best from your Solo 500 Amplifiers, it is important that they be positioned and wired correctly.

Unpacking

• We recommend that you retain the packaging in case you need to transport your power amplifiers at a later date.

• Take care when unpacking to avoid damage to the case.

Connections & Operation

Low power state

In normal operation, not using the 12V trigger, the power amplifier will go into low-power-state after 20 minutes of no audio. Any signal on the XLR or RCA will quickly bring the power amplifier out of low-power-state and start playing.

Front panel

1. POWER SWITCH - Switches the power ON/OFF 2. Linn Roundel - To show the current status of the Solo 500 power amplifier

Linn Roundel

Mains power OFF

Initial power on or programming state

150px Full power ON and operational

150px Going into low-power

Low Power state After 20mins of no audio (Waiting for audio signal or 12V trigger)

Waking up from low-power Going into low-power-state is the reverse of this motion.

Fault/Error state

Back panel

1. MAINS INPUT - To connect to the mains electricity supply.
2. EARTH TERMINAL -for use in countries without mains earth in power cable.
3. POWER OUTPUT - 4 mm terminals for connecting to the loudspeaker.
4. BALANCED INPUT/OUTPUT ¹'(XLR-Line level)
5. RCA INPUT/OUTPUT ¹ RCA-Line level
6. INPUT SELECT - To connect XLR or RCA inputs.
   
7. SERVICE PORTS ² - Covering Exakt & USB sockets (These are ONLY used for Service options.)
8. Brightness & Auto-Standby, - Switched brightness levels for the front panel status roundel and auto-Standby options
9. # 12V trigger³,- To remotely bring the amplifier in/out of lower power state using a 12V control signal.
10. FALLBACK - T0 force the Solo 500 in to software fallback mode for programming.

Notes:

¹ The IN/OUT sockets are hard wired together to allow amplifier daisy-chaining.

² Exakt sockets & USB-C sockets ONLY for Software update, configuration setup.

³ Check #12V Trigger section below

12V Trigger

The 12V Trigger input trigger interface, which can be linked with other devices to switch into / out of a low power state.

• When low, the power amplifier goes into a low-power-state.
• When 12V is applied to this input, this brings the power amplifier out of low-power-state and ready to play within 1second.
• However, if 12V has been applied, but there has not been an audio signal for an extended period of time, this will put the power amplifier into low-power-state.

Auto-Standby settings

This allows more settings in the Auto-Standby function and overall power used.

3: No auto-standby. (Never enters Low-Power mode)

2: "Shallow" auto-standby after 20 minutes without a signal. Almost immediate audio upon waking up.

1: "Deep" auto-standby after 20 minutes without a signal. Audio will take a few seconds before waking up.

LED brightness control

Control for front panel roundel brightness

3: Maximum brightness.

2: Mid-level brightness.

1: Minimum brightness.
