Balanced or unbalanced isn’t the question here. BALUS stands for Balanced-Unbalanced. Due to the stereo TRS jacks used in the PLI05, it can cope with both balanced and unbalanced signals. The PLI05 is so to say the PLI02’s little sister. Both boxes can be used to convert balanced to unbalanced and both use so called line isolating transformers to realize a galvanic separation. They are connected between mains powered devices to reliably prevent ground loop hum. The PLI02 was designed for use with XLR connections and for low impedances (600 Ohms). The PLI05 on the other hand with its jack connector is better for higher impedances. It covers a wide range from 600 Ohms to over 10 k Ohms. The attached diagrams for harmonic distortion, frequency- and phase characteristics demonstrate this quite
clearly. To prevent loss of level make sure that your input impedance is not higher than the output impedance. Both devices are suitable for high levels of up to +20dBu.

Inline Transformer IA-2
The model IA-2 line matching transformers !S designed to properly match a low impedance signal to a low impedance source. The advantage of "ground lift" switching allows to optmize hum problems.

AR-133 Ενεργό di-box με phantom και μπαταρία
The unit includes phantom power and battery supplies as standard. Should the phantom power from the console fail or be accidentally switched off, the AR-133 automatically switches over to the internal 9V battery providing uninterrupted use.
The unit is housed in a rugged aluminium extrusion case, with robust polyurethane end-cheeks which give the AR-133 a very distinctive look.
Input connectors are both 1/4" jack sockets and an XLR socket, the latter meaning that the AR-133 can be used to convert unbalanced signals to a balanced output on XLRs throughout.
The arched case allows cables to run back underneath the unit from the end for neat cable management.
Input attenuation is 0, -20 or -40dB, making the box suitable for instrument, line or amplifier levels on inputs. On the output side, a ground-lift switch is provided for quick solutions to ground-loop problems.
The AR-133 uses an enhanced version of the same audio path as the AR-116, now regarded by many people as a reference standard. The sound quality is legendary, particularly on acoustic and bass guitars.
Numerous applications can be satisfied by the AR-133. For example, as well as the traditional guitar use, the AR-133 can be used with keyboards, DJ consoles, amplifier outputs, and other electronic sources.
An additional bonus is the ability to use the AR-133 as an active balancing device.
Active DI-Box SM-60
The electronic Direct-Injection Box SM-60 allows direct connection of electronic music instruments such as keyboards, synthesizers, electric and electronic pianos, etc. with mixing consoles in PA-systems and in recording studios. The SM-6 is designed for applications, where a passive DI-Box does not perfom satisfactorily, i.e., where the output level of a passive DI-Box is too low for the microphone input section of the mixing desk. Because the input impedance of the SM-6 is above 5 MOhm, instrument outputs are not loaded or in any other way adversely affected. The voltage ratio from input to output is 1: 1 and is always sufficient for connection with any microphone input. Input connectors are 1/4" phone jacks, output connector is a Switchcraft D3M; output is 600 Ohms, transformer balanced. The output level may in certain cases overload microphone inputs - the line input section of the mixing console must then be used for connecting the SM-6. The unit operates with a 9 V battery or phantom powering from 24 to 48 volts.
