Description

Palmer PMAIN Passive 2-Channel Line MergerSometimes it is necessary to send two stereo signals to one device, for example, when two mixing consoles have to drive a stereo power amplifier. In practice, this is rarely possible without ground loops occurring. The Palmer main solves this type of problem. It mixes two stereo input signals via a resistor matrix, whereby the input pair A is galvanically isolated by a transformer in order to avoid ground loops. The Palmer main works purely passively.

Sometimes it is necessary to send two stereo signals to one device, for example, when two mixing consoles have to drive a stereo power amplifier. In practice, this is rarely possible without ground loops occurring. The Palmer main solves this type of problem. It mixes two stereo input signals via a resistor matrix, whereby the input pair A is galvanically isolated by a transformer in order to avoid ground loops.

The Palmer main works purely passively. The result is a particularly low noise floor and a neutral sound. Thanks to large transformers, it can handle high-level signals up to +20 dBu without distortion. The transformers also make it possible to assign the input pair A unbalanced while the output signal remains balanced.

The passive mode of operation without a power supply makes the Palmer main particularly reliable and failure-proof. The aluminium/steel housing and XLR sockets are also best suited to the rough everyday life on stage. The Palmer main merge box solves typical sound reinforcement problems in the simplest way with uncompromised sound quality.

Good fit
Color: Light Grey, Size: Medium
A nice vest and a true slim fit. Good quality for the price and no satin back, the material is used for the whole vest, allowing it to be worn without a jacket and still look smart. I am 6' 3" and 200lbs with a slim build, the Medium size fit like a glove, snug but not tight as a waistcoat should be.

Good Fit, Fold Lines
5'9, around 125-130 pounds, and the Small fit me just fine. Adjuster strap provides a great range of... adjustment. Good waistcoat if you are looking for something quick and cheap. With it being cheap, however, the material suffers. Due to it being folded while in shipping, there are seem lines going down the sides of the waistcoat which make it poke out and look awkward.
