User manual PRO-JECT BOX S

[. . . ] INSTRUCTIONS FOR USE Pro-Ject Phono Box S Dear music lover, thank you for purchasing a PRO-JECT AUDIO phono amplifier. In order to achieve maximum performance and reliability you should study these instructions for use carefully. ! Warning of a hazard for the user, the unit or possible misuse. [. . . ] Never place any naked flame sources, such as lighted candles on or near the device. The product shall not be used in damp or wet locations, next to a bathtub, sink, swimming pool or any other similar conditions. ! Settings Use the dip switches at the bottom of the unit to set input gain, input capacitance and input impedance. To find out which type your cartridge is please consult the literature accompanying your cartridge. The literature for cartridges should also specify the correct input impedance (low-output MC cartridges) and the correct input capacitance (high-output MC and MM cartridges), into which the cartridge is designed to work. If in doubt please consult your dealer. ! To alter settings the unit must be disconnected from the power supply and the amplifier.

Make all connections whilst the phono amplifier is disconnected from the power supply. Take care to connect the left and right channels correctly. The right channel is usually marked red, the left channel black or white. Do not connect the phono amplifiers output to a phono input (sometimes labelled gram, disc or RIAA) on the amplifier. Never use any other power supply than the one supplied with the unit. Connecting the record player Connect the tonearm signal lead to the In of the phono amplifier. The earthing wire may be connected to the screw terminal if you encounter hum problems when using the record player. Connection to the amplifier Connect the Out of the phono amplifier to a line input (such as AUX, CD, Tuner, Tape or Video) on your amplifier. Mains power connection Connect the low voltage plug from the power supply to the Power 18V " socket of the phono amplifier before connecting the power supply to the mains. Stand-By The button on the front panel of the unit alternately turns the power on or returns it to standby mode. The blue LED above the stand-by push button shows that the unit is switched on. 4 © Audio Trade GmbH · Pro-Ject Phono Box S · Revision 2013. 1. 15 Technical specifications Pro-Ject Phono Box S Typical for low output MC cartridges, B typical for MM or high output MC cartridges * Input capacitance is irrelevant for low-output MC cartridges Input impedance: 10ohms, 100ohms, 1kohm A Input capacitance / impedance: 100pF, 200pF, 320pF and 420pF */47kohms B Together with other input impedance settings without any influence!Input gain: 40 and 43dB B / 60 and 63dB A Noise floor: 94dB (A weighted) at 40dB and 43dB input gain 75dB (A weighted)at 60dB and 63dB input gain THD: <0, 01% at 40dB and 43dB input gain <0, 05% at 60dB and 63dB input gain RIAA-equalisation curve accuracy: 20Hz - 20kHz / max. 0, 4dB Subsonic filter: at 20Hz with 12dB/octave Input: 1 pair RCA/phono sockets Line-level output: 1 pair RCA/phono sockets Outboard power supply: 18V/500mA DC, suitable for your country's mains supply Power consumption: 85mA DC, <1W in standby Dimensions W x H x D (D with sockets): 103 x 36 x 104 (115)mm Weight: 570g without power supply A Potential incorrect use and fault conditions No signal on one or both channels: No connection between player and phono amplifier or amplifier.
